Flat / X-over switch allowing the 'satellite' speaker
systems, connected to the stereo output (2), to receive a
full-range signal or the upper audio range only. In both
conditions the signal is affected by the volume control (5)
❚
Button up (crossover off). 'Flat' mode: the output signal is
'full bandwidth'.

Button pushed (crossover on): X-over mode': 100Hz

20kHz
high pass filter output signal (100Hz, 24dB/ oct.).
NOTE: to avoid misoperation, this button is recessed: use a tip
(pen or pencil) to switch it.
2
2 unbalanced XLR male sockets for the stereo output.
3
2 balanced XLR female sockets for the stereo input.
4
2 balanced XLR male sockets for the 'link' outputs
allowing parallel connection of active speaker systems.
5
Input level control.
Allows to adapt the input sensitivity of the built-in power
amplifier to the output level of the mixer.
If you are using a Montarbo mixer (or any other mixer having
an output level of 0dB), turn this control fully clockwise to its
maximum setting.
6
Ground/Lift switch: this switch allows to lift signal ground
from chassis ground (but the chassis is still connected to the
safety ground). This allows to lower annoying hums caused
by 'ground loops' when more units are connected.
7
Mains power switch.
8
Built-in fuse.
9
Power supply socket with male Power Con
®
connector.
For the preparation of the cable for the Power Con
®
connector see page 13.
