CONTROLS AND CONNECTIONS
DUAL STEREO MULTIEFFECTS DSP
With 56-bit internal DSP and 24-bit Delta-Sigma conversion, the
two internal effects (205 programs each) provide high performance
digital audio processing combined with extremely easy operation.
26
2-Line (E1 and E2) Liquid Crystal Display. Shows the numbers
◗
and the names of the currently selected program.
27
E1/E2 BUTTON: it allows operating on E1 or E2 lines on the
◗
LCD (E1 and E2 are the two groups of effects).
28 PROGRAMS selection knob: allows selecting one of the
◗
205 programs available for each of the two effects (E1 and E2).
29 LOAD BUTTON: allows loading and activating the program
◗
selected with the PROGRAMS knob.
= shows that the selected program has been loaded.
= shows that the selected program has not been loaded yet.
30
INPUT LEVEL: 5-segment input level LED indicator.
◗
A good setting of the effect sends (E1 and E2) on each channel will
produce continuous lighting of the green LED segments, while the
red segment must flash only occasionally.
◗ If the red LED is continuously lighted it indicates signal overload
and it is necessary to reduce the effect send volumes (E1 and E2)
on individual channels.
31 TONE control: turning this control clockwise produces a
◗
gradual decrease in high frequencies. Fully anticlockwise the re-
sponse is flat.
32 A / B / C / D / E / F: monitor sends (pre-fader). They allow to
◗
adjust the level of the stereo effect in the monitor outputs.
33 BAL: balance. Allows to adjust the level of the stereo signal
◗
in the L and R master outputs.
34 ON: effect on/off button, with green LED indicator.
◗
35
VOLUME faders. They control the effect's volume on master
◗
outputs.
connections:
◗
36 EFF FT/SW - MUTE: jack sockets for connection of remote
◗
footswitches. They allow remote control enabling/disabling of the
built-in effect processors. This is possible only when the "ON"
buttons are pushed. The red LED indicators light when the effects
are 'off' (muted).
EXTERNAL EFFECTS SENDS AND RETURNS
37
1 / 2 EXT. EFF. SEND: level controls for the external effects
◗
sends. They adjust the level of the signals at the 'EFF SEND 1' and
'EFF SEND 2' jack outputs. These signals are the mix of the E1 and
E2 controls of all input channels.
Each one of the two STEREO RETURNS features:
38
VOL: adjusts the volume of the return signal sent to the
◗
master L/R outputs.
39 BAL: stereo balance of the external effect. Allows to adjust
◗
the level of the stereo signal of the effect in the L and R master
outputs.
40
A / B / C / D / E / F: monitor sends controls.
◗
They set the level of the external effect return in the two monitor
outputs.They depend on the volume control (38).

ENGLISH
connections:
◗
41
EFF SEND 1/2: jack output socket for the external effects sends.
◗
42 STEREO EFF RET 1/2: jack inputs for the stereo external
◗
effect return.
• The EFF RET L and R inputs are standard stereo line inputs. You can thus
use them to connect any line signal (such as the L/R outputs of a second
mixer, instruments, expanders...)
Connect the inputs of the external effects to the EFF SEND 1/2
◗
sockets.
Connect the L and R outputs of the external effects to the
◗
L and R EFF RET 1 and EFF RET 2 inputs of the effects return.
• For a mono effect connect its 'only effect' output to the 'L / mono' socket.
Use the E1 and the E2 controls on each channel to adjust the
◗
quantity of channel signal to be sent to the external effects, the
EFF SEND 1 and EFF SEND 2 controls (37) to adjust the quantity
of signal to be sent to the EFF SEND 1 and EFF SEND 2 outputs.
Use the A, B, C, D, E, F, VOL and BAL controls (40, 38, 39) to adjust
the effect return level in the monitor 'A', 'B', 'C', 'D', 'E', 'F' outputs
and in the master 'L' and 'R' outputs.
On the channels where the external effect is not desired turn the
effect send (E1 or E2) knob fully anticlockwise.

AUXILIARY OUTPUTS SECTION:
This section includes 6 identical channels (A, B, C, D, E and F).
The following description is valid for each of them.
43 A / B / C / D / E / F outputs level: 12 segment LED array gives
◗
istantaneous reading of A, B, C, D, E and F outputs level.
44 HIGH / MID kHz / MID dB / LOW: 3-band Equalizer with
◗
parametric control of the mid range for the A, B, C, D, E, F monitor
outputs. The High and Low controls act on fixed frequency bands,
the Mid control allows to choose the frequency to be boosted or cut.
HIGH: adjusts the amount of boost or cut in the high frequency
range (±15dB@15kHz). Turning the control clockwise increases the
amount of high frequencies, counter-clockwise decreases it.
The response is flat at the center position.
MID kHz: chooses the frequency to be boosted or cut (0,18÷3kHz).
MID dB: adjusts the amount of boost or cut (±15dB) in the frequen-
cy choosen by means of the MID kHz control.
Note: If the MIDdB control is set at '0' (centre) there will be no alteration
in the mid frequency band (independently of the MIDkHz control setting).
LOW: adjusts the amount of boost or cut in the low frequency
range (±15dB@50Hz). Turning the control clockwise increases the
amount of low frequencies, counter-clockwise decreases it.
The response is flat at the center position.
45 PFL: this push-button allows to check the level of the aux
◗
output signal by means of the PFL level indicator (57) and to listen
to it on headphones, even if the fader is closed. It is so possible to
adjust the aux mix and output equalizer without sending it to the
output. If more than one PFL switch is on, the phones amplifier and
the PFL LED indicator will receive the sum of the selected signals.
Note: To allow headphone listening of a PFL signal, the PFL switch of the
master module's headphone amplifier (56) must be pressed.
46 A, B, C, D, E and F output level fader.
