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-
