ꢀ.3 The Amplifier
TECTON amplifiers are fitted with Switched Mode Power Supplies (SMPS),which
significantly reduces the weight and size (only 2U) of the amplifier. Using SMPS,
the 2 symmetrical supply voltages (ꢀ symmetrical supply voltage for TECTON
22.2 and TECTON 14.2) of the power amplifier are more stable than the power
supplies used in conventional amplifiers.
The TECTON is a Class-H power amplifier with a power output of:
TECTON 38.4 ꢀ900 W per channel @ 4Ω
3800 W in Mono-Bridge @ 8 Ω
3800 W in Parallel-Mono @ 2 Ω
TECTON 32.4 ꢀ600 W per channel @ 4Ω
3200 W in Mono-Bridge @ 8 Ω
3200 W in Parallel-Mono @ 2 Ω
TECTON 24.4 ꢀ200 W per channel @ 4Ω
2400 W in Mono-Bridge @ 8 Ω
The TECTON 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 TECTON allow access to the functio-
nality.
2400 W in Parallel-Mono @ 2 Ω
TECTON 28.2 ꢀ420 W per channel @ 2 Ω
2840 W in Mono-Bridge @ 4 Ω
Since some of the externally mounted controls have multiple functions, it is
important that users should familiarise themselves thoroughly with the entire
range of controls.
2840 W in Parallel-Mono @ ꢀ Ω
TECTON 22.2 ꢀꢀ40 W per channel @ 2 Ω
2280 W in Mono-Bridge @ 4 Ω

3.2. On/Off Switch
3.3 Mounting
The On/Off Switch is a rocker-type switch. It is located on the right side of the
front panel. To turn the amplifier on,push in on the upper part of the switch.This
initiates start-up by activating the inrush current limiter. During power up the
Clip and Signal LEDs from both channels will light up in red for a few seconds.To
turn the amplifier off, push in on the lower part of the switch.
Use four screws and washers when mounting the amplifier to the front rack rails.
For mobile use, the amplifier should also be secured using the ꢀ9” mounting
elements on the rear panel.

NOTE:This switch does NOT disconnect the amplifier from mains.
Make sure the mains power socket or an alternative disconnect device is
near by and easily accessible.
The switch initiates start-up by activating the current limiting function.
As soon as the power amplifier is connected to the mains power supply, a vol-
tage is supplied to both the line-filter and the fused input of the controllable
rectifier. Disconnecting the amplifier from the main power supply can only be
achieved by physically separating the amplifier from the mains by pulling the
mains plug. The mains plug therefore has to be freely accessible. Disconnect
the mains plug from the mains during a lightning storm or when the amplifier
remains unused or unsupervised for a prolonged period of time. Alternatively,
you can disconnect the amplifier via an external all-pole disconnection from
the mains.
If a power cut occurs while the amplifier is switched on, it will restart automati-
cally once the power supply has been restored. All settings operation prior to
the loss of power will be maintained.

3.4 Cooling
3.6 Mode Indicators
Under normal operation of the power amp, overheating should never be a
problem. 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.
On the front panel there are two yellow LEDs to indicate the mode that is set. In
stereo mode (2-channel) none of them will be lit. In Parallel-Mono the (PM) LED
will be lit and in Mono-Bridge, the (MB) LED will be lit.
The efficiency of the cooling will depend on the immediate environment (e.g.
an enclosed rack, direct sunlight). If the amp is installed in a case, the open area
at the back of the case must be at least ꢀ40 cm².This area should be in line with
the amp.
If this can not be achieved a forced ventilation system has to be used.
3.5 Ground Lift
The input signal ground (pin ꢀ for all 4 XLRs) is connected to the ground of the
mains supply. In order to avoid ground loops, this connection can be separated
via a resistor. The ground potential of the power amp and the ground of the
loudspeaker always remain connected to the ground of the mains supply
regardless of the setting of this switch.

The output terminals of the two channels are configured in parallel using an in-
ternal relay.The (single) load is connected either to the output of channel A or to
that of channel B (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.The chan-
nel B-Input is inactive – turn the volume of channel B down to zero.
This mode is useful when, for example, 3 identical loudspeakers are to be
operated with the same power.

4.2.3 Clip LEDs
4.3.3 DC Protection
If the power level is overloaded, the Clip LED will light up.
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 correspond-
ing channel will be muted.If DC was only applied for a short moment,the ampli-
fier will release mute and work as normal. If DC is applied for longer periods or
several short times the amplifier will switch to standby mode.
Switch off the amplifier, wait until the power LED stops flashing and switch the
amplifier on again.
4.3.4 DC Servo
To prevent DC Offset at the speaker output the TECTON is fitted with a DC
Servo.
4.3.5 Over Current Protection
4.3 Power Amp Protection Systems
Over current is permanently controlled in the output stage.There are two limit-
ing 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.
4.3.ꢀ Clip Limiter
If the power amp is overdriven, the clip detection triggers the Attack-Release-
Circuit (ARC). The ARC delivers the control voltage for the gain reduction. Two
different attack modes (fast and slow) could be chosen with the Clip Limiter
switch (see 4.1.4 Limiter Switch).
4.3.6 Thermal Protection
There are several sensors in the amp in order to ascertain temperature data. If
a temperature of more than 85 °C is detected at the heat sinks, the input signal
on that channel is reduced. If the temperature exceeds ꢀ00 °C, the main SMPS
is switched off.
4.3.2 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
channel. In mono modes the rails of both channels are switched back.

4.4 Mains Protections
4.5 Main SMPS Protections
4.4.ꢀ Inrush Current Limitation
4.5.ꢀ Over Current Protection
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.
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.
4.4.2 Mains Over Voltage Detection
Mains over voltage detection is always operative. When the mains voltage
exceeds approx. 267 V (230 V operation) or ꢀ34 V (ꢀ20 V operation), the ampli-
fier will be switched off. The system will try to start in intervals and will return
with a soft start when the regular mains voltage returns.
4.6 Fan
The fan mounted in the TECTON operates permanently, but as long as the
temperature remains below 40 °C it runs at its slowest speed and can hardly
be heard. The highest detected temperature from either channel controls the
speed of the fan:above 40 °C the speed is increased until it reaches its maximum
value.
4.4.3 Mains Failure Detection
Mains failure detection is always operative. When the mains supply is inter-
rupted for about 2 mains cycles, the amplifier will be switched off. When the
mains voltage returns to a normal value, a soft start occurs.
4.4.4 Fuse Protection
The average mains current can peak temporarily, depending on the load im-
pedance and type of signal, at values significant higher than the nominal value
allowed by the fuse protection.
Continuous monitoring of the fuse protection status allows the conditions that
would trigger the fuse protection to be predicted. In order to avoid shut-down
of the amplifier due to current overload, the amplitude of the input signals will
be limited and by hard overloads the amp will be muted for the time.

5.ꢀ E.U.I.2 (Extended User Interface)
5.ꢀ.ꢀ What Are The Possibilities Using The E.U.I.2?
CAUTION! Always switch off and unplug the TECTON from mains, before
making alterations to the E.U.I. card.
The E.U.I.2 is a very powerful interface, which allows access to most of the
system parameters, such as volume, input signal, mute, output current, clip
signal, temperature and more. You can use the E.U.I.2 as a filter, remote control,
signal processing device and more… Please contact your dealer/distributor or
CAMCO to customise the E.U.I.2 according to your wishes.
The E.U.I. card contains the Rear XLR Panel as standard. Other input cards are
available (See 5.1.1 What Are The Possibilities Using The E.U.I.2?).
To remove the E.U.I.2 unscrew the two Phillips head screws at the left and right
end of the XLR-Panel and carefully slide out the E.U.I.2.
To refit the E.U.I.2, carefully insert it. Pay attention that the cable is not clamped.
ATTENTION! Don’t forget to tighten the screws!

Check AC plug.
Confirm that AC outlet works by plugging in another device.
Output Current LEDs are lit
Signal LEDs responding to signal level
Clip LEDs not lit
A faulty speaker or a loose connection could cause this. Check the wiring
and try another speaker.
Indication:
The signal source might be clipping. Keep the TECTON volume pots at
least halfway up so that the source does not have to be overdriven.
Keep the TECTON volume pots at least halfway up and try changing input
sensitivity from ꢀ,4 V to 32 dB or 26 dB with the gain selector on the rear.
Output Current LEDs are lit
Signal LEDs not lit
Make sure the signal source is operating and try another cable.
Check position of volume pots.
Indication:
6.4 Problem: Hiss
Output Current LEDs are lit
Signal LEDs responding to signal level
Check the speaker wiring for breaks.
Try another speaker and cable.
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.
Indication:
Avoid boosting the signal further between the source and the amplifier.
Signal LEDs show red (Protect Mode)
Overheating will cause protective muting. Check for proper ventilation.
If the fan isn’t running the amplifier requires servicing.
6.5 Problem: Squeals and Feedback
Microphone feedback should be eliminated 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.
6.2 Problem: No Channel Separation
Check the mode indicators on the front panel and make sure the mode
selector 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.
