7.0 DUAL GROUP MODULE
The Vision dual group output module is a basic output design whereby all signal flow takes place from the
group summing amps to the group output as well as to the main left right outputs.
7.1 Return Section
The return switch selects whether the input signal for the LEVEL pot is from the group output or from the
RETURN A input on the back of the console.
7.2 Equalizer section
This two-band fixed equalizer is very effective in its design. There are two bands, the high and low are fixed
frequency with shelving characteristics with a boost or cut of 16 dB at 1 2kHz and 60Hz.
The
EQUALIZER
is placed in the monitor path of the subgroup module.
All level controls are center detented making neutral positions easy to establish.
All frequency ranges have been carefully selected following extensive examination of all types of music (and
noise) which makes this equalizer a pleasure to work with. Noise and distortion are kept to an absolute
minimum.
7.3 Sub switch
The SUB switch has several functions which will be explained below.
In the up position the monitor section will follow the signal at the group output and the pan-pot follows the
monitor section.
With the SUB switch in the down position, the monitor section follows the RETurn input and the output of the
level control is sent to the the group mix buss of that same group. At the same time the pan-pot follows the
group output A.
The first set up is mostly used for track laying, The recorded signal is sent to the multitrack from the group
output jack. The group monitor pot and pan-pot follow the signal coming from the tape return A.
The second set up with the SUB switch down is most frequently used in live sound situations, whereby the
grouped signal needs to be directly send via the pan-pot to the main mix buses. An effect return signal
is coming into the group module via the return input and mixed with the "dry" grouped signal prior to the
group fader. So balance between dry and wet signal is always guaranteed.
7.4 Auxiliary section
The Vision group module has two auxiliary send busses. While in the tracking session, some aux sends are used
for feeding the headphones and some are used for effects sends.
Aux
iliary sends
1&2
are on dual concentric controls. The top control is the send control for aux 1 and the
bottom control is the send for aux 2. These Aux busses are normally used for stereo headphone sends in the
tracking session. Each individual aux send can be set pre or post by internal jumpers.
Factory pre-set is Aux 1=post and Aux 2 =pre.
7.5 Level and pan-pot
The group Level pot is fed by the RETurn switch, either from the group output or the Return A input.
The Pan-pot either follows the level pot or the group output dependent upon the SUB switch setting.
The MUTE switch is a momentary switch that controls a silent FET switch to mute the monitor section. The
FET can also be controlled by the optional MIDI mute module.
The
SOLO
switch always receives a pre LEVEL signal coming from the group output or the RETurn input (Tape
replay)
This is independent upon the SIP master status settings in the master module.
A solo indicator LED is fitted next to the solo switch.
The Vision has a high quality 100mm fader. Alps or P&G faders are optionally available.
7.6 Led bar section
The led bar is a peak reading 13 segment led bar following as a factory preset the RETurn signal, thus indicating
the incoming signal from the return input.
The led bar can be set to the group output permanently.
Note: This peak reading device indicates a -6 dB reading below actual level with a steady sinus tone. So when the
ou4dBu, the meter will indicate -6 dB
"The B section is identical to the A section".
