THE CHASSIS SYSTEM
INTRODUCTION
The Vision is available in three frame sizes; 19" (14 module positions), 38, and 46 module positions.
The basic frame has two blank modules, both located on the extreme left and right of the frame.
An exception is the 19" rack frame, which does not have blanks on either side.
The extreme left and right blanks on the larger frames cannot be used for input modules as they conceal mechanical
constructions.
The frame 38 will fit 40 input modules ( mono, stereo, group, matrix or master modules).
The frame 46 frame will fit 48 in/output modules.
The master section in the 19" rack version needs to be installed on the far right side of the console.
In other frames the master section and all other modules can be installed wherever most suitable, but the request
must be made at the time of ordering.
Vision manual page:7
2. THE MASTER STANDARD/DELUXE MODULES
2.0 Master section description
The Vision has two master modules which are completely modular.
All inputs and outputs are located on the back of the console. The paragraphs below give a
description of each module section.
2.1 Control Room Monitor Section
The Solo section is a soft switching circuit that automatically brings in the soloed channel
when a solo switch is activated. When The SIP switch is in the down position, all solo switches
on the input modules are in the stereo-in-place mode when activated. A LED indicator is
also fitted next to the SIP switch to show when a solo circuit is activated.
The master Aux solo switches do not react on the SIP switch, they shall always be AFL. ( After
Fade Listen). in the Control Room Monitor output and Headphone outputs.
Above the CRM pot, there are the two CRM signal sources. With these switches in the up
position, the CRM will monitor the stereo main outputs which is the sum of all the input
channels assigned to the master plus the group output modules.
The Vision has two dedicated unbalanced +4 dBv or -10 dBu tape return inputs which can be
wired to the outputs of stereo master machines, cassette machines, CD players, or DAT
recorders. Utilizing any of these switches enables play-back or post tape monitoring of a master
mix.
The CRM
level controls the total outgoing level to the control room monitors amps.
The Vision has two CRM systems intended for use with large monitors and near field monitors
which are switchable via the
CRM 2
switch.
2.2 Mono output
The Vision has a separate stereo summed balanced mono output with its own level control.
The output is wired post master left/right inserts.
2.3 Oscillator section (de-luxe master module)
A single 1 kHz frequency, low distortion, phase shift type oscillator is fitted. (more frequencies
are optional)
There is a front panel accessible level control with which to adjust the oscillator for precise
alignment of the console and tape machines. The level ranges from infinity to +20 dB.
The oscillator is either routed to the stereo mix busses and Aux send busses
(ALL) or exclusively to the AUX 1 and 2 busses. This switching is coupled to the Talk back switching.
NOTE:
The CRM will dim 20dB when the oscillator and or Talk back is active.
2.4 Master/channel meters.
The Vision master is fitted with peak reading, high resolution, LED bar meters with attack and
release times which conform to world standards. The attack is 10msec. for a 20 dB range and the
release is 1 .5msec.
NOTE:
Peak reading meters give a reading 6 dB below the actual level when using a sine wave. For example, +4 dBu
at the output connectors would give a reading of -6 dB on the meter using the oscillator.
Vision manual page:8
0dB on the meters equals +10dBu on the outputs!
If V.U. reading led bars are ordered, they will have attack and release times of 300msec. and a
+4 dBu level on the output connectors will give a 0 dB reading on the meter.
Measuring the +4 dB output level of the channel or master with a AC voltmeter would give a 1.22 volt
reading. The LED meter would actually be reading -6 dB on the scale. When monitoring program
material, you will see higher levels on the peak reading meters.
2.5 Talkback section
The talkback section allows all communication functions from the control room to the
Aux Sends and
GROUPS.
The unbalanced talk back input (wired balanced) can be routed to the 4/8 aux sends, all group outputs
and main outputs by activating the
ALL
switch. The Aux 1-2 switch only routes the TB signal to
the Aux 1-2 busses. In both cases the CRM output is dimmed by 20 dB.
The talkback switch is a momentary type which allows you to talk to the above mentioned outputs.
2.6 Auxiliary masters
The auxiliary master sections are identical in function. The first module controls the Aux send busses 1,
2, 3, & 4 and the second module controls Aux send busses 5, 6, 7, & 8. Each Aux master pot controls
the sum of all channel or group aux send busses. The solo switch sends the (post fader) aux buss
signal to the control room monitors. The master SOLO LED indicates the activated solo switch.
2.7 Phones section
The
PHONES
section performs in a similar way to the CRM section.
The phones output simply follows the control room monitor output but with its own level control.
2.8 Stereo return sections
The Vision console has a stereo return control in both the master output modules.
The stereo signal is directly assigned to the master left/right busses.
Vision manual page:9
2.9 Master in/outputs
The Vision can be interfaced with external equipment such as two track master machines,
signal processors, headphone amps, and power amps. Interfacing is possible using the connectors
on the master back panels. Listed below are all inputs and outputs for the two master modules.
Partly the connectors are on the back panels of the modules. Some output connectors are mounted
in the frame along with the MIDI interface connectors.
The Standard Master module houses (from top to bottom) the Aux
1 to 4 outputs ( which are ground compensated) and the stereo Aux "A" return jack. Below these
connectors are the master inserts left and
right.
In the Frame of the Vision series
you will find the balanced XLR
outputs of the Left/right and
Mono outputs.
The ground compensated
Control Room Monitor left and
right outputs.
The unbalanced CRM 2 outputs
as well as the unbalanced two
track returns.
On the right side of the consoles frame there are the MIDI in/out/thru din connectors which are needed when the
MIDI mute system is installed and communication needs to be made between external signal processors and /or midi
sequencers. A separate manual is available for the MIDI control module which will be connected to the REMOTE
connector.
The 19" rack version has an internal power supply and the desktop versions have an external power supply fed by a Speakon
connector that can handle a lot of current.
The DELUXE Master module (Aux masters 5 thru 8 and Talkback) has the following connectors on the back plate.
The connectors on this module back plate are the ground compensated Aux 5 thru 8 master outputs and
the Aux B return input. Aux sends 1 thru 8 are used for sending signals within the console to eight different signal
processors such as digital reverbs. These outputs are ground compensated.
Vision manual page:10
3. STANDARD MONO INPUT MODULES
The Vision standard mono input module is a basic input design whereby all signal flow takes place from the
microphone to the direct output as well as to the main left right outputs and group outputs.
3.1 Input section
The input section controls all incoming signals from microphone and line inputs.
A
+48V
phantom power switch for condenser microphones or direct boxes can be silently switched in or out
of the circuit.
LINE
switches the microphone input to line input on the channel.
The line has its own balanced input amp and is controlled by the active (dual) gain control.
When the
GAIN
control is accurately set, it is possible to achieve the very best signal to noise ratio and
maximum headroom required for high quality recordings. This control is for adjusting the
line
and
mic
inputs (with separate electronics), although only one knob adjusts the dual pot.
3.2 Equalizer section
This three-band parametric equalizer is unique in its design. There are three bands, the high and low
with a boost or cut of 16 dB and the mid band is sweep able with a boost or cut of 16 dB.
The
HF
(high frequency) section is a fixed frequency shelving type at 12 kHz with a maximum boost or cut of
16 dB.
The
LF
(low frequency) section is a fixed frequency shelving type at 60 Hz with a maximum boost or cut of
16 dB.
The
MF
(High / Mid Freq.) section has level and frequency controls with variable frequency ranges from 200 Hz
to 7,000 Hz and has a maximum boost or cut of 16 dB. The bandwidth has a Q factor of 1.5.
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.
3.3 Auxiliary Send Section
The Vision standard mono 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.
Aux
iliary 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 3&4
are on single controls with a post fader factory setting. A pre-fader selection is easy accomplished.
The
DIRECT
output follows the post fader signal coming from the fader creating a dedicated aux send for that
channel only. Or it can be used as a multitrack send. The output level is 0 dBu. The output is ground
compensated.
Vision manual page:11
3.4 Channel assign / 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 ach 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 pan-pot to the stereo mix buss while the pan control
pans the signal between the main stereo mix L / R busses and / or the odd and even group summing busses if
assigned.
The Vision's summing amp and internal structure means that it is extremely quiet and distortion free,
therefore a direct button to bypass the amps is not necessary.
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, 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.
Fader section
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.
Vision manual page:12
3.5 Input and Output connectors
Every channel has the following connectors at the back of the housing. The balanced
LINE
input is a stereo
1/4" jack socket:
Tip = hot
Ring = cold
Sleeve = shield
The INSERT is on a stereo jack socket.
Tip = return
Ring = send
Sleeve = shield
The ground compensated
DIRECT
output is a stereo 1/4" jack socket:
Tip = hot
Ring = cold
Sleeve = shield
The
REMOTE
connector is internally wired to a 4 pin connector that can be wired to a
faderstart switch if ordered:
Tip = normally open
Ring = normally closed
Sleeve = centre contact
A balanced XLR connector is for the
MIC input.
Pin 1 = shield
Pin 2 = hot (in phase)
Pin 3 = cold (out of phase)
