5. Standard stereo input module
This stereo module is a flexible stereo module. This module can be used for stereo keyboards, drum machines,
or any device needing two inputs on one fader. The paragraphs below describe the stereo input module in full.
5.1 Input section
Line B
switches the
Line A
input to the line B input of the channel.
The line has its own balanced input amp and is controlled by the active (dual) gain control.
The input section consist of a stereo
GAIN
control.
The gain control is a dual pot used to adjust the gain of two line amps (balanced stereo input).
The adjustment range is from - 20dB to + 20 dB.
NOTE:
In the line B input an optionally available RIAA phono correction amplifier is available.
5.2 Equalizer section
The three band stereo equalizer was designed for the type of equalization needed for stereo returns.
The high frequency band is a shelving type at
12,000 Hz. The low frequency band is a shelving type at 60 Hz. The mid band has a bell curve at 1 kHz.
Each band has a boost or cut of 16dB.
5.3 Aux and send section
All aux sends are summed stereo signal sends.
The Vision standard stereo module has four auxiliary send busses. While in the tracking session, some aux
sends are used for feeding the headphones and some are used for effects sends. During the mix session, all aux
sends are used for effects sends.
Auxiliary sends 1 is switchable between pre and post fader. This Aux buss is normally used for stereo
headphone send in the tracking session. A PRE switch puts them pre fader for fold back purposes.
Aux 2,3&4 are on single controls with a post fader factory setting. A pre-fader selection is easy
accomplished.
5.4 Channel assign and fader section
The
Channel assign
section allows the user to assign to a maximum of 4 busses. The routing gives selection
to the 4 group modules using two pushbuttons. With each pair of summing amps, you have the choice of
assigning to the odd or even groups using the pan pot.
The
L/R
switch (in the assign section) assigns the signal to the stereo mix buss while the balance control
compensates for any unbalances in the input signal. The Vision's summing amp and internal structure means that
it is extremely quiet and distortion free.
The MUTE switch is a momentary switch that controls a silent FET switch to mute the channel. The FET can
also be controlled by the optional MIDI mute module.
The
SOLO
switch has two modes, stereo pfl (pre fade listen) or a non-destructive stereo solo-in-place
system. Master status switching (located in the master section) selects the “solo in-place” or “PFL” mode for
the entire console. Activating the solo switch in the pfl mode will send the pre-fader signal to the
CRM speakers. In the solo in-place mode, the post monitor pan pot signal is heard. 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. You can use any VCA
Mix Automation System which uses the faders and mute system in the Vision. The channels are prewired for
accepting any VCA automation system.
