Set Up
INPUTS - The V-01 Series amplifiers allow you to use two types of input connectors per channel, a XLR jack for balanced connections
and a 1/4” female jack that will accept balanced and unbalanced connectors. Use these connections to connect the output signal from
a mixer, cross-over or EQ to your V-01 Series amplifier. A balanced connection is recommended for cable runs longer that 20ft. When
constructing your own XLR cables follow the pin configuration describe below for proper connections. For cable runs shorter than
20ft. you may choose the 1/4” unbalanced input option. The 1/4” unbalanced input option may be more convenient for most users
due to the abundant supply of prefabricated cables available at your local audio dealer. You may use the two XLR “Input Thru” jacks
to jump a parallel connection to another amplifier or other device. For Example: Connect a XLR cable to the input of channel one. You
may now connect a XLR cable from the channel one “Input Thru” jack to the input jack of another amplifier’s channel one input. This
will reduce the use of “Y” cables.

OUTPUTS:
Binding Post/Banana Plug - Connect your speakers to the binding post outputs on the rear of the amplifier. The speaker wire may
be connect by bare wire (directly connected, usually for permanent connections), banana plug, or spade connec-
tor. Connections are made to Channels 1 and 2 output’s for stereo mode or across the red terminals of Channels 1
and 2 for Mono Bridge Mode.
Important Notice: Although a speaker will operate with the positive and negative leads plugged into either termi-
nal on the amplifier binding post, be sure to plug the negative lead into the black terminal and positive lead into
the red terminal. Ensuring proper polarity will avoid speakers being out of phase, that can cause a loss of bass

response.
Important Notice: Banana Plugs - When connecting your speakers to the amplifier using banana jacks; Be sure that the red and black
caps on the binding post are completely screwed in. Insert the banana jacks into the caps of the binding post, be sure that the banana
jack is inserted securely to avoid the risk of it popping out.

When connecting your speakers to the amplifier using bare wire; Unscrew the red and
black caps on the binding post, be sure not to completely remove or unscrew the red
and black caps. Strip back the wire insulation 1/2” (13mm). Insert the bare wire into the
hole that was reveled by unscrewing the binding post cap. After inserting the wire into
the binding post hole, screw the binding post cap down on the wire. To reduce the risk of
shock or damage to your amplifier, be sure that the wire connected to one binding post
does not come in contact with that of another.
Typical speaker output using bare wire. Insert
bare wire into the binding post and tighten.
Spade Connector: (Figure 8)
When connecting your speakers to the amplifier using spade connector; Unscrew the red and black caps on
the binding post, be sure not to completely remove or unscrew the red and black caps. Insert the spade con-
nector in to the binding post and tighten the caps down on the spade connector. To reduce the risk of shock
or damage to your amplifier, be sure that the wire connected to one binding post does not come in contact
with that of another.
When connecting your speakers to the amplifier using banana jacks; Be sure that the red and black caps on
the binding post are tighten down completely. Insert the banana jacks into the caps of the binding post, be
sure that the banana jack is inserted securely to avoid the risk of it popping out.
Mono Bridge Connections:
Figure 10
Mono bridge operation connections will follow the above descriptions however, when operating in mono
bridge operation the speaker connections will run between the two positive (red) leads. Use channel two pos-
itive output terminal for the negative connection and the channel one positive output terminal for the positive
connection.
Typical speaker output using
spade connectors. Insert
bare wire into the binding
post and tighten.
Stereo Connections Using the Neutrik Speakon output connectors:
Recent regulatory requirements in Europe have outlawed the use of the dual banana plug and force amp users to terminate their speaker
cables with spade lugs or bare wire ends. This is not advantageous to most users that want to reconfigure their systems or quickly
change out an amp. The Neutrik Speakon® connector provides the most convenient solution to this problem, eliminating the need for
spade plugs or bare wire end cables. Major speaker manufacturers have been using Speakon connectors on their products for years,
so chances are you are ready to use the Speakon connection. With Speakon connectors, you can connect straight from the amplifier
to the speaker. The Speakon connector used on this amplifier meets all known safety regulations. Once wired correctly, the connector
cannot be plugged in backwards, causing the type of inverted polarity situations that have become common with banana hookups. This
connection will provide a safe, secure and reliable method of connecting your speakers to your new amplifier. You can purchase the
Speakon® NL4FC connectors from your local audio dealer.

SPEAKON ASSEMBLY: You will need a pair of Neutrik Speakon® NL4FC
connectors. You will also need high-quality two or four conductor speaker
cable, a pair of needle-nosed pliers and a 1.5-mm Allen key to assemble the
Speakon connectors to your speaker wire. To assemble the Neutrik Speakon
NL4FC connector, complete the following steps:

OPERATING MODES: Always configure your amplifier operating mode before beginning operation. If you want to change it dur-
ing performance. You must decrease the gain controls to their lowest levels to protect the speakers from any popping noise.
Stereo Operation - Page 18/Figure 17 details an example of a typical stereo set-up. Connect your inputs into channels one and
two of the amplifier. Connect your speakers to the outputs on the rear of the amplifier. Be sure that your front gain controls are turned
down to their lowest level (full counter-clockwise). Turn your amp on. Turn your input source level up. Use your front gain controls to
regulate the output volume. Be sure not to raise the volume to the clip level, however an intermittent clip signal is acceptable.
Mono Bridge Operation - Page 18/Figure 18 details a mono bridge set-up. Be sure your amplifier and all other audio equipment
is powered down. Flip the Stereo/Mono Bridge switch to the Mono Bridge position. Connect an input signal to channel one. Connect
your speaker across the red output binding post, or pin 1+, 2+ of channel one speakon output jack on the rear of your amplifier. Turn
your equipment on (your amplifier should always be the last item you turn on). Apply an input source signal to your amplifier. Turn
channel two gain up. Use the channel one gain to regulate your amplifier output.
Bridged-Mono Mode Caution - The voltage across the output terminals of a bridged V-01 Series™ amplifier may equal or exceed
100 volts RMS and may be as high as 130 volts. Use fully insulated CLASS ONE wiring, and the load must be rated for up to 2500 watts
(@4 ohms)
Parallel Mono - “Parallel ” ties the two channel line inputs together so that they will both be driven by the same signal, without the
need for external jumpers or wiring. Both amplifier channels will operate independently. Though they carry the same signal, their gain
controls affect only their respective channels, and they both must use their respected speaker outputs. Never attempt to parallel the
speaker outputs, this may cause serious damage to your amplifier! This mode is recommended when using the V-01 Series™ to run
bass speakers, to achieve better low end. To run in parallel mono mode connect your system as you would if you were going to run in
stereo mode. Then flip the mode switch to “MONO.” Be sure the amp is off or the power is disconnected before making any changes.
Subwoofer Mode - This mode sends low frequencies to your speakers without the use of an external cross-over. The subwoofer
operation can be operated in stereo, mono, or bridge mono modes. Change the different operating modes by flipping the mode switch
on the rear of the unit to your desired operating mode. Also, set the subwoofer mode switch to the subwoofer position. Use the frequency
selector to adjust the subwoofer output frequency from 20Hz to 200Hz. The different subwoofer modes are listed as follows;
Bridge Subwoofer - This operation allows you to get the most possible power out of your amplifier for the sole purpose of running a
high powered subwoofer loudspeaker in mono. To avoid amplifier overheating, never run the amplifier below 4 ohms in this mode. In
this mode you may use the frequency adjustment on the rear of the amp, to control the frequency output level. Frequencies may be
adjusted from 20Hz to 200Hz. Page 17/ Figure 15 details a typical Bridge Subwoofer set up.
Stereo Subwoofer - This operation is similar to the Bridge Subwoofer operation but in stereo. This operation allows you to run several
subwoofers down to a minimum of 2 ohms. To avoid amplifier overheating, never run the amplifier below 2 ohms in this mode. Set up
this mode as you would a standard stereo set up. Be sure both channels are set to “SUBWOOF.” In this mode you may use the frequency
adjustment on the rear of the amp, to control the bass frequency output level. Frequencies may be adjusted from 20Hz to 200Hz. Page

Mono Subwoofer - This operation is similar to the Stereo Subwoofer operation but in mono. When running subwoofers it is usually
recommended to run them in mono mode to achieve a cleaner tighter low end. This operation allows you to run several subwoofers
down to a minimum of 2 ohms. To avoid amplifier overheating, never run the amplifier below 2 ohms in this mode. Set up this mode
as you would a standard stereo set up. Be sure both channels are set to “SUBWOOF” and the mode switch is set to “MONO.” In this
mode you may use the frequency adjustment on the rear of the amp, to control the bass frequency output level. Frequencies may be
adjusted from 20Hz to 200Hz.
One Channel Normal/One Channel Subwoofer (BI-AMP) - You may also use your amp to bi-amp your system. You may use one
side of the amp to power a subwoofer and the other side to power a full range speaker. Follow the set up guides listed above to mix
and match your operations.
PROTECTION:
Limiter - The V-01 Series™ series comes with a built in limiter. When the input signal overloads, the “CLIP LED’s” indicate a signal
overload, at this time, the master volume should be lowered to reduce distortion. If the input gain level is not reduced the built-in lim-
iter will activate. During signal overload, the limiter will reduce the input audio signal enough to minimize the amount of clipping. A
limiter takes the gain of an overloading signal and reduces it, the reduction in gain reduces distortion that can cause damage to your
speakers and amplifier. During normal operation below clipping, and momentary clips on peaks, the limiter does not affect the audio
signal and is inaudible. It will allow brief clipping of peaks and will only activate when continuous, hard clipping occurs. During exces-
sive clipping the limiter will reduce the audio signal enough to minimize the amount of clipping. When the input signal decreases
enough that clipping ends, the limiter will deactivate and cease its gain reduction. The limiter has a fixed threshold and can not be
adjusted.
Safe Power Levels at Different Output Loads:
8-Ohm Loads: The amplifier can operate at practically any power level without risk of overheating. However, if it is pushed hard
enough to continually light the “CLIP ” indicator, the amplifier’s average output power can reach 150 watts.
4-Ohm Loads: If the “CLIP” indicator flashes occasionally, the amplifier is approaching its maximum long-term power capacity. If it is
lit about half the time, the amplifier channel will probably go into thermal protection within a few minutes.
2-Ohm Loads: Except for an occasional flash, keep the “CLIP” indicator dark to avoid overheating the amplifier channel. Clipping
should be kept to a reasonable minimum. An amplifier’s peak current draw at full output power into 2 ohms is several times what the
“normal ” draw is, but its various protection circuits will prevent this condition lasting more than a minute or two.
Short Circuit Protection - The V-01 Series™ series amplifiers all come with built-in Output Short
Circuit Protects. The Output Short Circuit Protection protects the output devices of the amplifier
from short circuits and stressful loads. If your speaker lines short, the amplifier automatically detects
this problem and discontinues operation for that channel. If one side of your amplifier becomes
shorted and goes into protect mode, the other side will continue to operate normally. During short
circuit protection, the "Clip" LED and “Protect" LED will light simultaneously indicating amplifier
fault. All channel output during the “Short Circuit Protection" will be interrupted (i.e. no sound out

put). Short Circuit Protection can usually be traced back to the signal output line (i.e. speaker line). Check the line from the output ter-
minal of the amplifier to the speaker. If this line good, check the internal speaker connections and components. A short circuit will usu-
ally be traced to a bad cable or a bad speaker component and is rarely traced to the amplifier itself.
Thermal Protection - Dual variable speed fans on the V-01 Series amplifier provide adequate cooling. During low level output the fans
run at normal speeds. During high output and as heat raises, (exceeding 90°C.), the fans will run at higher speeds to aid the cooling
process. If the heatsink temperature exceeds 91°C., the amplifier will mute until the amplifier cools down. When the amplifier cools
below 90°C., the amplifier will return to normal operations. Be sure not to operate your amplifier below the minimum load ratings to
reduce the risk of overheating problems.
Input/Output Protection - The input circuits are isolated by 10k resistors. An ultrasonic network uncouples RF from the output and
helps keep the amplifier stable with reactive loads.
Operating Voltage (AC Mains) - The serial number label indicates the correct AC main voltage. Connecting to the wrong voltage is
dangerous and may damage the amplifier. Always be sure the source voltage for your areas matches the required voltage for your
amplifier.
Gain Controls - The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to
adjust the amplifier so no “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion
during normal operation.
AMPLIFIER FEATURES:
THRU - Thru will allow the user to daisy-chain one amplifiers signal input into another amplifier. Plug the signal source outputs into the
first amplifier’s input, patch from the amplifier’s THRU jacks to the next amplifier’s input, and so on, daisy-chaining as many amplifiers
as there is no excessive level loss. Is not affected by crossover setting.
GROUND LIFT SWITCH - Applying or lifting the ground switch will change the level for background noise and hum, if the noise level
remains the same in either position, it is better to keep the ground lift switch in the ground position. This will eliminate 60Hz cycle hum
that is sometimes induced when mounting several units in the same rack.
OPERATING VOLTAGE (AC MAINS) - The serial number label indicates the correct AC main voltage. Connecting to the wrong voltage
is dangerous and may damage the amplifier.
GAIN CONTROLS - The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to
adjust the amplifier so no “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion
during normal operation.
LED INDICATORS - Each channel has five LEDS. Two LEDs indicate signal level activity; one green LED and one yellow LED. One red
LED indicates signal clipping. One red LED indicates protections mode for shorts/ overload. One green LED indicates an active signal.
Both channels will also share the center blue LED that indicate the amplifier operating mode.
