INSTALLATION GUIDELINES:
 Install the unit in a well-ventilated location where it will not be exposed to high temperatures or humidity.
 Placing and using the unit for long periods near heat-generating sources such as amplifiers, spotlights, etc.
will affect its performance and may even damage the unit.
 The unit can be mounted in 19-inch racks. Attach the unit using the 4 screw holes on the front panel. Be
sure to use screws of the appropriate size. (screws not provided)
 Take care to minimize shocks and vibrations during transport.
 When installed in a booth or flight case, please make sure to have good ventilation to improve heat
evacuation of the unit.
 To avoid condensation to be formed inside, allow the unit to adapt to the surrounding temperatures when
bringing it into a warm room after transport. Condense sometimes prevents the unit from working at full
performance.
CLEANING THE APPLIANCE:
Clean by wiping with a polished cloth slightly dipped with water. Avoid getting water inside the unit. Do not
use volatile liquids such as benzene or thinner which will damage the unit.
Clean the ventilation holes regularly with a vacuum cleaner. This increases the cooling capacity of the
amplifier fans and helps preventing temperature overheat.
CONNECTIONS
Be sure to turn off the unit before you make changes to the wiring. For the signal inputs we recommend
using the XLR-connections. Use good quality signal cables to ensure excellent audio quality. For the
®
speakers you must use the Speakon outputs. In the description of the unit you will find more information on
how to connect the amplifier.
FUNCTIONS (FRONT)
1. VENTILLATION HOLES: during its operation the amplifier produces heat that needs to be dissipated.
The fans inside the amplifier must be able to evacuate the heat in the most effective way. Therefore is it
very important not to cover any of the ventilation openings as this may result in overheating. Clean the
ventilation holes regularly with a vacuum cleaner. This increases the cooling capacity of the amplifier
fans and helps preventing temperature overheat.
2. GAIN CONTROLS: These potentiometers are used to control the input sensitivity of the amplifier. Each
channel has its own control.
You can use these controls to set the maximum sound level of your setup:
 Turn both controls on the amplifier to the left.
 Put on some music on and make sure the VU meters on your mixer are at 0dB. (from time to time
the red zone is lit)
 Set the Master output from your mixer to maximum.
 Open the Gain controls from the amplifier until the maximum desired sound level is reached.
 Make sure nobody can reach the Gain controls of the amplifier.
You have just set the maximum level the DJ is able to produce. Your neighbors will be glad... (in some
cases the DJ is not )
Note: In Mono and Bridge mode, only the gain control of the left channel is used to adjust the input
sensitivity.

3. OPERATION MODE LEDS: These LEDs indicates the operation mode. Switch (14) on the rear panel is
used to choose one of these 3 possible modes:
 STEREO MODE: Both LEDs are off. This is the most common mode, both channels are working
separately.
 MONO MODE: 'MONO' LED is lit. Basically this is identical to stereo mode but the inputs of both
channels are linked so the output will be mono. In this case you only need to use the input of the
left channel to drive both output channels.
 BRIDGE MODE: 'BRI' LED is lit. Both channels are linked in "bridge mode" to obtain a mono
output with much higher power.
4. SIGNAL LEDS: these LEDs indicate that a music signal is present at the inputs.
5. CLIP LEDS: The LEDs will light up in the following situations:
 When the output signal has reached a high level which can result in distortion (clipping).
Meanwhile the signal limiters are working to keep the distortion low.
 While short-circuit happened in the output section. Turn-off the amplifier, check the speaker and
output wiring to find the problem(s).
6. LIMIT LEDS: [only on DIGIT 2K2 and DIGIT 3K6] these LEDs are lit in the following situations:
 When the output power exceeds the safe working range of the amplifier, the LIMIT LEDs are lit
while the current limiters come in action to reduce the dynamic range (current) of the output and
bring the amplifier back to its safe working range. In this case you are urged lower the input!
 While short-circuit happened in the output section and the amplifier is in protect mode. Turn-off the
amplifier, check the speaker and output wiring to find the problem(s).
7. PROTECT LEDS: The protection LED is on in the following situations:
 During the first seconds after switching on the amplifier.
 When the temperature of the power stage becomes too high.
 In case of a technical defect: DC protection!
 While switching the amplifier off, the "protect led" turns on for a short time.
8. MAINS SWITCH: Used to turn the amplifier on and off. A few seconds after switching on the amplifier it
is ready for operation.
FUNCTIONS (rear)
9. MAINS INPUT with IEC socket and integrated fuse holder, connect the supplied mains cable here.
10. FAN & VENTILLATION HOLES: during its operation the amplifier produces heat that must be
dissipated. The fans inside the amplifier must be able to evacuate the heat in the most effective way.
Therefore is it very important not to cover any of the ventilation openings as this may result in
overheating. On DIGIT 1K0 the ventilation holes are located on the left side, on DIGIT 2K2/3K6 the
ventilation holes are located on the back.
11. L+R SPEAKON OUTPUTS: use these Speakon
(impedance >4ohm) in stereo or mono mode. Wiring of these connectors is as follows:
 POS(+) = Speakon connector PIN1+ and PIN2+
 NEG(-) = Speakon connector PIN1- and PIN2-
12. BRIDGE OUTPUT: use this connector to connect your speaker
cabinet (impedance >8ohm) in bridge mode. Wiring of this
connector is as follows:
 POS(+) = connector PIN1+ and PIN2+
 NEG(-) = connector PIN1- and PIN2-
