VORTEX POWER AMP SERIES  
P.8  
1.3 The amplifier  
The VORTEX has been designed as an intelligent and powerful product for  
performing specialised tasks within a complex audio system. Users can adapt  
the power amp to meet their specific audio requirements before use. Controls  
mounted on the front and the rear of the VORTEX allow access to the  
functionality.  
The VORTEX is a Class-H power amplifier with a power output of 3 kW per  
channel / 2 Ohm load (6 kW in mono / 4 Ohm load) for VORTEX 6, 2 kW per  
channel / 2 Ohm load (4 kW in mono / 4 Ohm load) for VORTEX 4 and 1300 W  
per chanel / 2 Ohm load (2,6 kW in mono / 4 Ohm load) for VORTEX 2.6.  
It is supplied by Switched Mode Power Supplies (SMPS).These SMPS’s radically  
reduce the weight and size (only 2U) of the amplifier. Using SMPS, the 3 -  
symmetrical supply voltages (2- symmetrical supply voltages for VORTEX 2.6)  
of the power amplifier are more stable than the power supplies used in con-  
ventional amplifiers.  
Since some of the externally mounted controls have multiple functions, it is  
important that users should familiarise themselves with the entire range of  
controls and programmable features before using the power amp.  
If you have questions about features of the VORTEX power amp that are not  
covered by the basic descriptions in this manual, CAMCO would be pleased to  
offer you further information. Alternatively, contact your dealer/distributor.  
The VORTEX also uses a microprocessor for controlling and monitoring the  
power amp. Controlling a power amp designed for use in modern sound  
systems, has four main advantages over more traditional power amp systems:  
Reduced Distortion  
Improved Noise Characteristics  
Integrated Remote Control  
Indication of protection or failures by different LED sequences

3.2 Precautions  
NOTE:This switch does not isolate the appliance from mains.  
It initiates start-up by activating the inrush current limiter.When the amp is  
connected to mains, only the line-filter and the input of the silicon controlled  
rectifier (fused) are energised.  
When mounting or connecting the amp always disconnect it from mains.  
3.3 Mounting  
Use four screws and washers when mounting the amplifier to the front rack  
rails. Rear support is also recommended, especially in mobile and touring use.

3.4 Cooling  
3.6 Wiring  
Under normal operation of the power amp, overheating should never be a  
problem.The temperature of the cooling air will depend on the immediate  
environment (e.g. an enclosed rack, direct sunlight) and on whether the front  
filter is clogged. If the amp is installed in a case, the open area at the back of  
the case must be at least 140 cm².This area should be in line with the amp.  
If this can not be achived a forced ventilation system has to be used.  
The air is taken in from the front and out through the back, it is of course  
essential that while the power amp is running air is able to circulate around  
it freely.  
3.6.1 SPEAKON Connection

3.5 Ground Lift  
The input signal ground (pin 1 for all 4 XLR’s) is tied to the ground potential  
in the mains supply. Opening the ground lift switch causes this connection  
to be broken.This allows ground loops that sometimes occur in practice to  
be eliminated.The ground potential of the power amp and therefore of the  
loudspeaker outputs is independent of the switch setting and remains at the  
ground potential of the mains supply.

The output terminals of the two channels are configured in parallel using an  
internal relay.The (single) load is connected either to the output of channel 1  
or to that of channel 2 (as if in stereo).While the total output of the amplifier  
remains the same and the output voltage level is also the same as in stereo  
operation, the minimum impedance that can be connected is reduced by half  
due to the fact that current capability is doubled. Only Channel A-Input is  
active. This mode is useful when powering 3 speaker cabinets in parallel. A load  
balancing is achieved in this case.  
The second channel processes the same input signal, but with reversed phase.  
The (single) load is connected between the two positive channel outputs using  
a suitable connected SPEAKON connector.While the total output of the ampli-  
fier remains the same, both the available output voltage and the minimum  
impedance that can be connected are doubled, as compared with stereo oper-  
ation. Only Channel A-Input is active. A signal feeding Channel B will have no  
effect on the output.  
NOTE: For parallel mono operation, to prevent damage of one SPEAKON  
connector and to reduce loss of power because of contact or cable  
resistance, it is highly recommended to wire speaker loads using  
both 2 channel SPEAKON connectors with all contacts connected.

3.7 Input Signal Chaining  
The input signals to the XLR connectors can be hard-wired in parallel using  
a switch on the E.U.I. (See 3.6.2, Switch 1, 5.1, Extended User Interface and 5.1.1,  
Input Signal Parallel Switch).This serves as a replacement for an external short  
XLR female - XLR male cable for parallel linking the signal inputs.  
Switch S1  
CAUTION:  
Linking channels together can cause damage to system components if for  
example two inputs are used with separate ‘LF’ and ‘HF’ feeds.  
If the amplifier is to be used for ‘LF’ and ‘HF, ensure this switch is set to  
STEREO Mode before switching on.

4.1 Precautions  
improved noise characteristics.The implementation is comparatively simple:  
the volume potentiometers pass the relevant control information (quieter or  
louder depending on the adjustment made to the potentiometers) to the  
microprocessor.The microprocessor then adjusts the power amp output using  
various strategies implemented in software. In addition to improved technical  
parameters, this approach allows a significant reduction in the number of  
components and circuits required.  
Only connect the VORTEX amplifier to a appropriate AC circuit and outlet,  
according to the requirements indicated on the rating plate label.  
The volume pots are also used to set the CAI-address.  
(See 5.2.3, CAI Address Settings)  
NOTE: Even under normal conditions the mains current can reach levels  
(up to 60 A / 230 V and 120 A / 115 V); this could cause lamps to  
flicker if connected to the same mains as the amp.The impedance of  
the AC circuit should be less than 0,157 Ohms to avoid flicker according  
to EN61000-3-11. Ask / inform your local power provider. Don’t even  
think about measureing this with your ohmmeter.This may damage your  
meter, caution - high voltage hazards!

4.2 Controls  
4.2.1 Volume Control  
4.2.3 Limiter Switch  
A microprocessor-controlled DCA (Digital Controlled Attenuator) with a control  
resolution of 12 bits per channel is integrated into the signal path.This means  
that the signal is not subject to an A/D followed by a D/A conversion with  
associated losses. Each channel is governed by a linear potentiometer with 41  
notched settings.These settings have been selected to correspond to human  
hearing characteristics (logarithmically) and therefore guarantee an optimal  
range of settings for practical applications. Each channel can be set individually  
except when operating in mono mode whereby only ChA is active.  
This switch is located at the rear of VORTEX. It allows you to set the mode of  
the limiter.There are three modes:

4.3 Indicators  
4.3.1 On / Failure Indicators  
Under normal operation, after the amp has started, the green power LEDs are  
permanently lit. A variety of different sequences of flashing LEDs are used to  
indicate other operating states and errors in one of the channels of the  
power amp. (See 6.0,Trouble Shooting)  
The green section is subject to analogue control.The brightness is proportional  
to the output current in the channel.The LED is visibly lit above around 1 Amp,  
while full brightness corresponds to the maximum rated current. If the LED is  
lit red only, no load is applied to the outputs or Clip is active with a duty cycle  
of more than 10 %.  
When under load, there is also a certain current that flows when controlling  
the power level; the green section will be lit appropriately. If the power level is  
taken to the limit, the green and red sections will appear mixed, resulting in a  
shade of yellow that depends on the current. If the microprocessor detects a  
clip signal with a duty cycle of more than 10 % within a time interval of 50 ms,  
then it suppresses the green section so that the clip LED appears only red.  
Careful analysis of the various dependencies when comparing channels that  
are subject to identical control (possibly in several different power amps) will  
allow conclusions to be drawn about the inherent impedances. This can aid  
the detection of incorrectly wired components and faults in loudspeakers at  
an early stage.  
4.3.2 Signal Indicators  
The green signal LED is illuminated when the voltage level at the output  
reaches approx. 4 V; this corresponds to a power of approx. 4 W at an  
impedance of 4 Ohms.

4.4 Power Amp Protection Systems  
maximum out of it, switch Speaker Protect off. For all other applications (e.g.  
Full Range) it’s recommended to switch Speaker Protect on.  
4.4.1 Clip Limiter  
If the power amp is overdriven, the clip detection circuit triggers the micro-  
processor.The processor reduces input signal level by controlling the DAC.  
The strategy is implemented in software. For sinusoidal signals the  
microprocessor limits the input signal level with the result that the non-linear  
distortion factor never exceeds 1 %.  
4.4.4 SOA Protection  
Whenever the power transistors leave their Safe Operation Area (SOA), the  
SOA-protection in stereo mode switches back the current rail of the respective  
power stage. In mono modes the rails of both channels are switched back.  
4.4.5 DC Protection  
The clip limiter can work on each channel independently (except in mono-  
operation).  
Each output of the power amp is constantly monitored for persistent DC  
voltage levels. If the 3 V thresholds are exceeded at any of the outputs, the  
channel at that output will be automatically disconnected.The microprocessor  
performs a sophisticated strategy to locate the cause of DC. If short-term DC is  
detected, the amplifier will recover and continue to operate. DC can be located  
in the Output stage, Driver stage or at the input of the amplifier.  
To disable the Clip Limiter, see 4.2.3, Limiter Switch.  
4.4.2 Under Impedance Limiter  
As a result of incorrectly connected or defective loads, under impedance or  
even short circuits may be presented to one or both power amp channels. In  
order to detect an under impedance, the microprocessor calculates the result-  
ant impedance. If an impedance of less than 1.33 ohms/channel is detected, the  
microprocessor limits the signal to the power amp until a subsequent  
measurement indicates that impedance has risen to a safe level.Whenever the  
under impedance limiter is active, the corresponding channel’s power LED is  
turned off. (See 6.0,Trouble Shooting)  
Output stage  
When DC is located in either output stage, the amp stops the main SMPS  
and mutes the amp where DC was detected.The On-LEDs will show a  
different flash sequence. (See 6.0,Trouble Shooting)  
Driver stage  
When DC is located in the driver stage only the defective channel’s output  
stage and DCA are muted.The other channel still works.The On-LED of the  
defective channel will start the flash sequence. (See 6.0,Trouble Shooting)  
4.4.3 Speaker Protect Limiter  
Whenever the Safe Operation Mode (SOA) protection of the power amp  
switches back the current rail there could be a small clipping at the output;  
but the microprocessor is also triggered by this protection and will reduce the  
signal level immediately to minimise the effect.  
Amplifier Input  
When DC is located at the input stage only the DCA of the affected channel  
is muted. (The other channel continues to operate normally). If the DC  
signal at the input vanishes the microprocessor will de-mute the affected  
channel and the amplifier will work as usual again.  
User can decide either to use speaker protect or not.When you use this amp  
for low frequencies (SUB bass / bass) and you want to squeeze the absolute

4.4.6 DC Servo  
4.5.3 Mains Failure Detection  
To Prevent DC-Offset at the Speaker output the VORTEX is fitted with two  
DC-Servos. (Hence there are no capacitors in the signal path!)  
Mains failure detection is always operative.When the mains supply is  
interrupted for about 2 mains cycles, the amplifier will be switched off. When  
the mains voltage returns to a normal value, a soft start occurs.  
4.4.7 Power Amp Over Current Protection  
Over current is permanently controlled in the output stage.There are two  
limiting levels of over current depending on output voltage.These limits will  
be set automatically. This improves reliability without degrading sound quality  
when driving complex loads.  
4.5.4 Fuse Protection  
Depending on the load impedance and type of signal levels, the effective  
mains current can, even during normal operation, reach a level several times  
higher than its nominal value for short periods. Repeated peaks of this nature  
will also cause the average value to increase. In such cases, the internal mains  
fuse and external 16 A circuit breaker acts as abottleneck, and would trip if the  
average current remained too high for an extended period. In order to avoid  
this unsatisfactory operation, the mains fuse is simulated inside the amplifier  
and provides the microprocessor with information. Prior to the point when the  
circuit breaker would trip, a signal is sent to the microprocessor, which then  
instantaneously reduces the signal level. After the known recovery time for the  
fuse has elapsed, the signal is again adjusted to its normal level.This offers  
reliable operation of a 6 kW VORTEX on 16 A Mains at 230 V and  
30 A at 115 V.  
4.4.8 Power Amp Thermal Protection  
The microprocessor uses several sensors in the amp in order to ascertain  
temperature data. If the microprocessor detects a temperature of more than  
85 °C at the heat sinks, the input signal on that channel is reduced.  
The power LED of the overheated channel will start a blinking-sequence  
(See 6.0,Trouble Shooting)  
4.5 Mains Protection  
4.5.1 Inrush Current Limitation  
4.6 Main SMPS Protections  
Within 2 seconds of the amplifier being switched on, the inrush current limiter  
will increase mains current from nearly zero to nominal value.This value  
depends on program material, output level and speaker loads.  
4.6.1 Main SMPS Over Current Protection  
Main SMPS (Switched Mode Power Supply) Transformer current is continuously  
monitored. If over current occurs, the main SMPS immediately stops working.  
Should there be an internal failure, this feature prevents other parts being  
damaged.  
4.5.2 Mains Over Voltage Detection  
Mains over voltage detection is always operative.When the mains voltage  
exceeds approx. 267 V (230 V operation) or 134 V (110 V operation), the ampli-  
fier will be switched off. When the mains voltage returns to nominal value, a  
soft start occurs.  
CAMCO USER MANUAL  
VORTEX POWER AMP SERIES  
P.19  
4.7 Fans  
The fans mounted in the VORTEX operate permanently, but as long as the temperature remains below 40 °C they run at their slowest speed and can hardly be heard.  
The highest detected temperature from either channel controls the speed of the fans: above 40 °C the speed is increased until it reaches its maximum value.  
4.8 Filter Cleaning  
A removable filter system is provided on the air intakes to the cooling system. If the filter becomes clogged, the unit will not cool as efficiently as it should and may  
produce output levels that are lower than normal due to high heat sink temperatures.  
To clean, gently slide the whole plastic filter assembly to the left and release from the front panel. Carefully unclip the outer moulding to reveal the filter. Clean the filter  
with a mild dishwashing detergent and warm water. Once dry, insert the filter back into the cradle and cover with the surround moulding. Slide the whole assembly to  
the right to secure onto the front panel.  
Spare filter assembly’s may be ordered from your dealer.

5.1 E.U.I. (Extended User Interface)  
5.1.3 Accessories  
The E.U.I. slot contains the Rear XLR Panel and the Input Signal Parallel switch  
as standard. Other input cards are available (See 5.1.3 Accessories) Always switch  
off and unplug the VORTEX from mains, when working on the E.U.I.  
Different types of filters are available. For further information contact your  
dealer or CAMCO  
5.1.4 What Are The Possibilities Using The E.U.I.?  
The switches described below are not readily accessible and cannot be  
checked visually from the outside. To remove the E.U.I. unscrew the two Phillips  
head screws at the left and right end of XLR-Panel and carefully slide out the  
E.U.I.To refit the E.U.I into the VORTEX, carefully insert the PCB in the guide-rail  
(left/right) and slide it in.  
The E.U.I. is a very powerful interface, which allows access to most of the system  
parameters. For example: volume, input signal, mute, output current, clip signal,  
temperature and more. It makes it possible to utilise filters, remote control,  
signal processing, and more… Please contact your dealer or CAMCO to  
customise the E.U.I. according your wishes.  
Don’t forget to replace the screws!  
5.2 C.A.I. (Camco Audio Interface)  
5.1.1 Input Signal Parallel Switch  
5.2.1 Camco Audio Interface  
If you want to hard-wire the XLR input connectors together on the E.U.I., just  
change from Stereo to Mono using switch S1. Be careful when you do this!  
(See section 3.7, Input Signal Chaining)  
C.A.I. is a bus system, in which all significant device functions can be monitored  
externally and remotely controlled using a master PC. Up to 99 devices can be  
controlled in parallel in each phase of the bus system, which simply consists  
of a two-core insulated cable.The master can serve several phases for larger  
applications. For more information, please contact your dealer or distributor.  
5.1.2 Filter On / Off Switch  
If a filter is present on the E.U.I. this can be activated or bypassed using switch  
S2.  
5.2.2 Wiring  
To connect the VORTEX to your C.A.I. - system use a fully-wired telephone-type  
cable with RJ12 connectors. For longer distances use high grade cable like  
for RS485, DMX512 for AES/EBU digital audio.You can chain several VORTEX  
amplifiers using the second C.A.I. Connector on each amplifier. A linear net-  
work topology is recommend with 100 Ohm termination at its end. Please refer  
to RS 485 specifications.  
5.2.3 C.A.I. Address Settings  
Switch S2  
The C.A.I. address selection procedure will not affect the operation of the  
VORTEX but whilst this procedure is active, the Volume cannot be adjusted by  
using the Pots.  
CAMCO USER MANUAL  
VORTEX POWER AMP SERIES  
P.21  
NOTE: Ensure you return both pots to their original position after address  
selection is complete, otherwise the amplifier will change its volume level  
to the new pot positions!  
These sequences are repeated for 30 seconds (timeout).Then the Power LEDs  
return to their normal function.  
To change CAI address, turn the appropriate Volume Potentiometer to the  
required address (Volume Pot Ch A => TENS,Volume Pot Ch B => UNITS).  
5.2.4 To Activate CAI Address Selection Procedure  
Briefly press the ENTER -Switch.This push button switch (Enter - Switch) can be  
accessed through the 3mm hole in the front panel located between the main  
power switch and the LEDs.  
To adjust the address you can use the scale markings of the  
potentiometers.You will find the digits 0,1,2,3,4,5,6,7,8,9 on the 10 scale  
spacing .  
Enter Switch  
The current selected address will be immediately displayed BUT not automati-  
cally stored or activated! After each turn of pot you have another 30 seconds  
to timeout.You can leave this procedure without saving the new address by  
briefly pressing the Enter-Switch or waiting for timeout (as described above).  
To store and activate the new address you have to press the Enter-Switch for  
3 seconds.This new address is stored in an EEPROM, which holds the informa-  
tion even if the amp is subsequently disconnected from mains. Be sure to  
set the CAI-Master-PC to this new address. If not, the communication will be  
interrupted.  
After briefly pressing the Enter-Switch the actual address will be displayed by  
the power LEDs.  
5.2.5 CAI Status Indicator  
Flashing of Power LED channel A indicates the tens,  
This green LED indicates the presence of communication between PC and the  
amp.  
Flashing of Power LED channel B indicates the units of the address.  
For example: different address setting LED sequences:

Indication: On LEDs not lit  
Clip/Output Current Indicators not lit  
Indication: On LED(s) Sequence  
Check AC plug.  
Please refer to the On LED sequence table to find out which  
protection is active.  
Confirm that AC outlet works by plugging in another device.  
High temperature will cause an attenuation of output level so that under  
normal conditions the amp will never mute!  
Indication: On LEDs lit  
Signal LEDs not lit  
DC will cause the amp to mute or shut down.  
Make sure the signal source is operating and try another cable.  
Check Position of Volume Pots.  
Switch off the VORTEX and unplug the source from the amp’s input to  
prevent DC entering the amp via the signal source.Then switch on the  
VORTEX. If the On-indicator shows the same sequence, the amp will need to  
be serviced by a qualified technician.  
Indication: On LEDs lit  
Signal LEDs responding to signal level  
Check the speaker wiring for breaks.  
Try another speaker and cable.  
All other LED sequences that shut down or mute the VORTEX indicate a  
serious internal fault. At this point, turn the VORTEX off, remove AC power  
and have the amplifier serviced by a qualified technician.  
Indication: On LED(s) sequence  
The amplifier is in protective muting. Refer to On LED -  
flashing sequences table to find out the cause for the mute.  
Overheating will cause protective muting.  
Check for proper ventilation. If the fan isn’t running the amplifier requires  
servicing.  
6.5 Problem: No Channel Separation  
Check the mode indicators on the front panel.  
Make sure the mode-switch on the rear panel is in the stereo-position.  
Make sure other equipment in the signal path such as mixers and preamps  
are set for stereo, not mono.  
On the E.U.I., check the Input Signal Parallel Switch is in the stereo-  
position.  
6.4 Problem: No Sound or Sound is too Low  
Indication: On LED not or sporadically lit  
Signal LED off  
Clip/Output Current indicator lit green or red  
Under Impedance Limiter is active.The load impedance is  
abnormally low or shorted.  
Unplug each speaker one-by-one. If the On LED indicates normally when  
you disconnect a cable, that cable or speaker is shorted.  
Take care not to use too many speakers in parallel, which would result in -  
CAMCO USER MANUAL  
VORTEX POWER AMP SERIES  
P.24  
6.6 Problem: Distorted Sound  
Indication: On LED lit  
Signal LED responding to signal level  
Clip/Output Current indicator lit only green  
A faulty speaker or a loose connection could cause this. Try another  
speaker and check the wiring.  
The signal source might be clipping. Keep the VORTEX volume pots at  
least halfway up so that the source does not have to be overdriven.  
Try changing input sensitivity from 1,4 V to 32 dB or 26 dB at the  
Gainswitch.  
6.7 Problem: Music Sounds Frequency Filtered  
If you have installed an optional filter module on E.U.I check the filter  
on/off-switch to be in off-position.  
6.8 Problem: Hiss  
Unplug the amplifier input to confirm that the hiss is coming from the  
source or from a device upstream.  
Erratic or popping noises indicate an electronic fault in the  
offending unit.  
To keep the noise floor low, operate the primary signal source at full level,  
without clipping.  
Avoid boosting the signal further between the source and the  
amplifier.  
6.9 Problem: Squeals and Feedback  
Microphone feedback should be controlled with mixer controls. If noise  
continues to build up with no microphone gain, there is a serious fault in  
the signal processors or cables.Working in succession from the signal source  
towards the amplifier and check each device in the signal path by reducing  
its gain or by unplugging it.
