ATTENTION!

The following special limitations apply to the console and must be observed in order to maintain safety and
electromagnetic compatibility performance:

POWER CONNECTION

The console should only be operated with the power supply connected to ground via its mains supply connector.

AUDIO CONNECTIONS

The console should only be operated with high quality screened twisted pair audio cables. All connector shells
should be of metal construction so that they provide a screen when they are plugged into the console. All JACK
connector shells should be connected to the cable screen. All XLR connectors should have pin 1 connected to the
cable screen.

ELECTRIC FIELDS

If the console is operated in an electromagnetic field that is amplitude modulated by an audio frequency signal,
the signal to noise ratio may be degraded. Degradation of up to 60dB may be experienced under extreme conditions
(3V/m, 90% modulation).

INSTALLATION

There are a number of points to consider when installing a mixing console. Many of these points will have been
addressed before the console is even unpacked but it is worth repeating them.

POSITION

The console should be located in a convenient space commensurate with the use to which the console is being put.
Ideally a cool area is preferred not in close proximity to power distribution equipment or other potential sources
of interference. Provision should be made for some flat surface surrounding the console to prevent people using it
as a table top.

INTERNAL POWER SUPPLY

he console is equipped with an internal power supply. It must be set for the appropriate line voltage and pluged

T

in to the mains outlet using the supplied cable.

MAINS VOLTAGE SETTING

The console is shipped with a specified mains voltage setting
(see rear panel marking). If the mains voltage is ever changed by
the mains voltage selector at the bottom of the console, the mains
fuse has to be changed as well to the rating matching the selected
voltage on the label.

ADDITIONAL EXTERNAL POWER SUPPLY FOR VENICE 240/320

The power supply should be located as far from the console as the connecting cable will allow. It should be set for
the appropriate line voltage and plugged into the mains outlet using the supplied cable. The external power-supply
overrides the internal supply after power on. The internal supply acts in this case as spare supply.

THE CONSOLE AND THE EXTERNAL POWER SUPPLY SHOULD NEVER BE OPERATED

WITH THE MAINS EARTH DISCONNECTED

Please note that the power supply contains LETHALVOLTAGES and that its rails can produce extremely
large currents which could burn out equipment and wiring if shorted. All testing and servicing should ONLY
be carried out by qualified engineers.

MIDAS VENICE

MONO INPUT

CHANNEL

6

The Venice Mono Channel is
equipped with an XLR input,
which can be used for Mic or
Line level signals up to
+22dBu. An additional ¼ inch
jack socket, provides an input
for line level signals, which re­quire protection against acci­dental 48 volt connection. The
Line input gives 20dB of per­manent attenuation to the input
signal which will allow the con­nection of extreme high line­level signals up to +42dBu.

The HI PASS switch connects
the the 80Hz hi-pass-filter in the
input channel signal path before
the insert point and equaliser.

The HI MID control gives conti­nuous adjustment of boost and
cut from + 15dB to - 15dB with
a 0dB centre detent.

The +48V led monitors if phan­tom power is assigned. The
+48V switch for each channel is
placed on the rear-panel of the
console. It connects +48V phan­tom power to the XLR input con­nector. This is suitable for a
condenser microphone or DI
box.

The GAIN control gives conti­nuous adjustment of the input
amplifier gain from 0dB to
+60dB for the Mic input and

- 20dB to + 40dB for the Line
input.

The TREBLE control gives con­tinuous adjustment of boost and
cut from + 15dB to - 15dB with a
0dB centre detent. The treble
equaliser acts on 12kHz with a
traditional MIDAS shelving re­sponse.

The LO MID control gives con­tinuous adjustment of boost and
cut from + 15dB to - 15dB with
a 0dB centre detent.

The BASS control gives conti­nuous adjustment of boost and
cut from + 15dB to - 15dB with
a 0dB centre detent. The bass
equaliser acts on 80Hz with a tra­ditional MIDAS shelving re­sponse.

The HI MID FREQ control gives
continuous adjustment of the fre­quency range that the hi mid
equaliser acts on from 400Hz to
8kHz with a 1 octave bandwith.

The LO MID FREQ control gi­ves continuous adjustment of the
frequency range that the lo mid
equaliser acts on from 100Hz to
2kHz with a 1 octave bandwith.

The EQ switch connects the
equaliser in the input channel si­gnal path.

7

The FX controls give continuous
adjustment of the post fader level
sent from the input channel to the
FX busses. The level adjustment
is from + 10dB to off with 0dB
at the centre position of the rota­ry control.

The AUX controls give conti­nuous adjustment of the level
sent from the input channel to the
AUX busses. The level adjust­ment is from + 10dB to off with
0dB at the centre position of the
rotary control.
AUX1 and 2 can be configured
globally for pre- or post-fader
operation by pressing the
PRE/POST switch on the appro­priate AUX-rail in the master
section.

The MON controls give conti­nuous adjustment of the pre- fa­der and pre- equaliser signal sent
from the input channel to the
MON busses. The level adjust­ment is from + 10dB to off with
0dB at the centre position of the
rotary control.

The PAN controls the channel
placement within the master ste­reo- or group mix and has a con­stant power law. i.e. - 3dB at the
centre position and 0dB or off at
either extreme setting.

The MUTE switch mutes the in­put channel at all points after the
insert send, including all auxili­ary sends.

8

The SOLO switch sends the in­put channel signal to the PFL /
mono-and AFL / stereo busses.
If the switch is engaged, the
mon1/2 meters are automatically
used for solo metering.

The FADER gives continuous
adjustment of the input channel
level from + 10dB to off.

The SIGNAL (-16dBu) / PEAK
(+16dBu) display monitors the
peak signal level of the pre fader
input channel.

The 1-2 switch connects the post
fader channel signal to the group
1-2 busses via the pan control.

The 3-4 switch connects the post
fader channel signal to the group
3-4 busses via the pan control.

The MAS switch connects the
post fader channel signal to the
master stereo bus via the pan con­trol.
