SIGNAL LED DISPLAY INDICATOR: this green LED indicates a safe operation. The output level will be
between -30 dB and 0 dB.
4
CLIPPING LED DISPLAY INDICATOR: this red LED indicates a state of over-modulation (distortion at
extremely high volumes). In this case check the output signal of your mixing panel and turn down the
GAIN CONTROL. Keep in mind that the amplifier cannot correct any distorted signal.

INPUT CHANNEL A and CHANNEL B: inputs through balanced XLR
Balanced / Unbalanced Input Connection
Both amplifier channels feature a balanced XLR female socket as well as a balanced 6.35 mm
phone jack socket.
Input cables must be screened!
If an unbalanced input signal is to be connected using an XLR plug, a wire bridge must be
inserted between PIN1 and PIN3 (see fig. on the left). For an unbalanced signal output, a
6.35 mm mono jack plug can also be used.
Remark: This amplifier will go into safety mode and switch off when overheated. When this happens, let the
amplifier cool down. The amplifier will be ready to use once the thermal protection is back to its ideal
temperature. This can take as much as 45 minutes.
6. Cleaning and Maintenance
All screws should be tightened and free of corrosion.
The housing and fixations should not be deformed, modified or tampered with; e.g. do not drill extra holes
in mounting supports, do not change the location of the connections…
The electric power supply cables must not show any damage. Have a qualified technician maintain the
device.
Disconnect the device from the mains prior to maintenance activities.
Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or solvents.
There are no user-serviceable parts, apart from the fuse.
Contact your dealer for spare parts if necessary.
