FIRST TURN ON
• Connect the passive loudspeakers, using cables with speakON connectors (4-5 outputs), depending on
impedance, max rated power, and amplier mode. Select the amplier MODE (5).
• Connect the inputs, using balanced cables with XLR connectors (6-7 input). Select the inputs
sensitivity (4).
• If needed, link the input LINK connectors, to relaunch the signal to a second amplier.
• Set the level knobs (8, 9) to the minimum level.
• Connect the mains cable (socket 1), turn on the amplier (11).
• Adjust the level knobs (8, 9), while the audio signal comes from your source.
INPUT SENSITIVITY / OUTPUT MODE
The user can select the input sensitivity and the output mode of the amplier.
The input sensitivity can be selected from (0.775 V, 1 V, 32 dB), depending on the charaterisctics of the
source.
The amplier can operate in three different modes:
- brigde (combines two input signal into one output signal to reach a higher power rating)
- parallel (route one input signal two both the outputs)
- stereo (the default mode, CH1 input is routed in CH1 output, CH2 input is routed in CH2 output)
See the upper table and the main tech specs for a further explanation.
