MASTER SECTION:
36 ➤ A / B: two 10 segment LED arrays give istantaneous reading
of A and B outputs levels.
37
➤
HF / HM / LM / LF: 4-band equalizer.
• HF: adjusts the amount of high frequencies.
•HM and LM: adjust the amount of mid-high and mid-low frequen-
cies.
• LF: adjusts the amount of low frequencies.
38
➤
A/B MONITORS: volume faders for the A and B monitor
outputs.
39
➤
L / R: two 10 segment LED arrays give istantaneous reading of
L and R outputs levels.
40
➤
L/R MASTER: volume faders for the left and right master
outputs.
41
➤
10-band stereo graphic EQUALIZER.
42
➤
EQ/FLAT: equalizer on/off switch.
43
➤
MONO: level control for the mono preamplifier output
(pre-master).
44
➤
TAPE IN: sets the level of the signal at the 'Tape in' socket of
the mixer.
45 ➤ PHONES: level control for the phones output.
46
➤
POWER: mains power switch.
● connections:
47
➤
A / B monitors: A and B monitor outputs with jack sockets.
■
Connect the A and B output sockets to the inputs of the self-
powered stage monitors. Adjust the A and B monitor send controls
on each channel, the tone controls (37) and the volume faders (38)
on the 'MONITORS' section. Each output can drive up to 10 parallel
connected powered monitors.

OUTPUTS L/R: output sockets for the internal power amplifiers.
Miniumum load impedance for each amplifier is 4
Ω
.
■ Connect one or two 8 Ohms speakers to each output.
Never use the internal power amplifiers with loads below 4 Ohms.
Adjust the volume fader on each channel as well as the L/R master
volume faders.
Note : Each output is fitted with 2 jack and 1 XLR sockets (parallel connected)
and features electronic and thermal protections, delayed power-up sequence,
automatic trouble-shooting and forced cooling.

➤
L/R INSERT: these stereo jack sockets allow to connect an
external equipment (e.g. a graphic equalizer, a limiter, an audio
processor) directly to the L/R master outputs. They are post-master
controls.
☛
see fig. 3 A page 21
These sockets can also be used as preamp-outputs for connecting
powered speakers or external power amplifiers. It is possible to use
the line and power outputs at the same time. Take out the signal
from the insert sockets by means of two stereo jack plugs, in which
you have previously joined the RING with the TIP (see example in
page 49) and send it to the inputs of the active speakers by means
of mono jack plugs.
☛
see fig. 3 B page 21
Note : If you plug mono jack into the stereo insert sockets, the power outputs are
automatically excluded.
50
➤
MONO: mono output (pre-master) for the connection to
mixers, studio consoles or any auxiliary equipment, external power
amplifiers or powered speaker enclosures. The mono output is not
affected by the master controls and has its own volume control.
☛
see fig. 5 page 22
51
➤
L/R TAPE IN/OUT: PIN in-out sockets. They allow connection
to stereo tape recorder.
■
Connect the L/R TAPE OUT sockets to the inputs of the tape re-
corder (line in) and the outputs of the tape recorder (line out) to
the L/R TAPE IN sockets of the mixer. If the TAPE IN inputs are not
used, it is suggested to keep the volume control fully closed, to
keep output noise to the minimum value.
■ For playback: switch the recorder to play and adjust the TAPE IN
volume control on the mixer (and the output volumes of the tape
recorder, if available).
■ For recording: switch the recorder to the 'record' mode and
adjust the input volume of the tape recorder. Set the output
volume control of the tape recorder to its lowest setting. In case
your tape recorder has no output volume control, disconnect the
cables from the TAPE IN sockets. The signal sent to the tape
recorder is unaffected by the L/R master faders settings.
Note : The L/R Tape inputs accept any line signal. You can thus use them as 2
extra line inputs to connect instruments, expanders or the L/R outputs of a mixer.
