Rear Panel Features

1. Cooling Vents.
Front to rear forced airflow.
Do not distruct air vents.
WARNING! Do not use switch 2 or 4
during operation. Only switch them
when amplifier is switch off!
2. Crossover Frequency Range
Selector to select the range of the filter
frequency.
x1 = 45-960Hz, x10 = 450-9600Hz
3. Crossover Frequency
Adjust the crossover frequency.
4. Filter Selection Switch
HIGH= High pass filter
LOW= Low pass filter
BYPASS= No filter, full range
5. Unbalanced 6.3mm Stereo Jack inputs.
Two 6.3mm jack female input connector
for connecting a signal source (mixer etc.).
6. Balanced XLR inputs.
Two 3-pin female XLR input connector for
connecting a signal source (mixer etc.).
7. Limiter Switch
Limiter for the automatic level limitation.
8. Mode Switch.
The amplifier can use 3 different modes:
stereo, bridge & parallel (mono). Choose
one of these functions:
Stereo mode: Standard left/right stereo
mode.
Bridge mode: This mode combines both
amps on one channel which results in
double power on this channel. Connects
the signal to the left input channel and the
output level can now be adjusted with the
left volume control.
9. Ground Lift Switch.
Allows circuit and chassis grounds to be
separated in case of problems with earth
loops (hum).
10. Bridge Speaker Outputs NL4.
Minium load in bridge mode 4 Ohm. Pin
+1 & +2 = + output, Pin -1 & -2 = - output
11. Binding Post Output Jacks.

channel. Minium load in bridge mode 4
Ohm.
12. Stereo Speaker Outputs NL4.
Minium load in stereo mode 2 Ohm. Pin
+1 & +2 = + output, Pin -1 & -2 = - output.
13. Mains Power Cable
To connect to a mean power socket (220-
