Soundcraft Vienna 2 1990 - Grey

Soundcraft Vienna II Channel Strip, Input Module RS5506 RS5508.

Got around 30 for sale,all packed and sealed in a box.

1 The sensitivity of both the XLR and HIGH IMPEDANCE (HI-Zjack) inputs is

adjusted by the SENS control. Both inputs are electronically balanced. The XLR

sensitivity is -2dBu to -70dBu and+ I0dBu to -20dBu (switched range). The High

Impedance input sensitivity is+ IOdBu to -20dBu.

2 The 48V switch enables 48V phantom power to be fed to the m1c input.

Modules may be optionally fitted with transfom1er coupling - refer to your dealer

for suitable transformers.

3 When the RNGE (Range) switch is depressed to lower sensitivity range of the

input is selected to allow line level signals to be used. The signal is taken from the

input XLR, unless a jack is inserted into the Hl-Z socket, when the signal from the

jack is used instead. Note that when the RNGE switch is released, the HI-Z input

socket cannot be used.

4 The Phase 0 switch reverses the phase of the selected input to compensate for

conflicting microphone position or for crossed wiring. This switch should normally

be released.

5 The High-pass Filter control is swept 20Hz - 400Hz. It has an OFF switch at

the ACW end of its rotation to switch the filter out of circuit.

Equaliser 

6 The Equaliser has four swept bands and is placed in circuit by pressing the EQ

switch. When switched out of circuit, its input is grounded. All 4 bands have

+/-15dB of cut and boost.

The HF section has a 20: I frequency range ratio covering )kHz to 20kHz. The Q

is fixed at about I. Cut and boost is by a centre detented control. The response is

normally shelving, but can be switched to peak/dip by the BELL switch.

The HMF section offers a 20: l frequency range ratio covering 600Hz to l 2kHz.

The Q is normally 1.3, but depressing the HI-Q switch gives a value of 2.6. Cut

and boost is by a centre detented control.

The LMF section offers a 20: l frequency range ratio covering 150Hz to 3kHz. The

Q is nonnally 1.3, but depressing the HI-Q switch gives a value of .6. Cut and boost

is by a centre detented control.

The LF section has a 20: I frequency range ratio covering 20Hz to 400Hz. The Q

is fixed at about 1.4. Cut and boost is by a centre detented control. The response

is normally shelving, but can be switched to peak/dip by the BELL switch.

Auxiliary Sends

7 Eight Auxiliary Sends are provided. Each has a rotary LEVEL control, and is

sourced from the post-fader signal, but may be switched pre-fade by individual PRE

buttons. The pre-fade signal source for Auxes 1-7 may be taken post-mute, pre-mute

and post-EQ, or pre-EQ and pre-insert. The source selection is by internal push-on

jumpers. The pre-fade signal for Aux Send 8 may be independently set post-mute,

or set to follow the pre-fade source for Auxes 1-7.

Three ON switches activate the sends for Auxes l & 2, 3 to 6, and 8. Aux 7 is always

active.

Direct Output

8 A post fade (nominal +4d8u) electronically balanced Direct Output is provided

on a rear panel jack socket. Provision is made for an output transformer to be

installed - refer to your dealer for suitable transformers.

Pressing the DIR switch replaces the post-fade channel direct output with the signal

from the Aux 8 pot, following the pre or post selection via the PRE switch.

Group Routing

9 The Routing Matrix is above the panpot, and allows the channel post-fade

signal to be fed to the eight Group and three Mix busses, which are all differential

with balanced drive for maximum noise immunity.

10 Routing to the L & R busses is by the L/R switch. These busses are sourced

after the centre detented active PAN control , but before the PAN switch, and are

therefore always affected by the panpot. When the MONO switch is pressed, the

pre-pan signal is routed to the mono bus.

11 Pressing PAN switches the PAN POT into the groups circuitry and allows

left/right panning between odd and even groups respectively.

7 Signal monitoring LEDs

12 A multi-point peak detector illuminates the red PEAK LED when there is a

level of +14dBu or greater at four critical places in the signa_l chain: the output of

Mic/Line amplifier, the wiper of the EQ switch and the output of the fader buffer

amplifier.

13 A green -30dB LED illuminates when a level of -30dBu or greater is present

at the output of the Mic/Line amplifier to show that the channel is active.

Channel Fader, Status and Mute

14 The channel fader sets the level sent to the mix, group busses and post-fade

outputs and has a gain of+ l OdB at the top of its travel.

The illuminated, mechanically latching SOLO and CUT switches, in conjunction

with the 8 MUTE bus switches control whether the channel is ON or muted.

When pressed, the LEDs in the selected mute switches glow, indicating readiness

to accept a Master mute. If the channel is muted via a Master mute bus, the

channel's CUT switch flashes to indicate that a non-local mute is in operation.

15 Pressing the CUT switch will always mute the channel via the soft muting

circuit.

16 If a MUTE bus is selected, pressing the corresponding mute master (located

on the Master module) will mute the channel in the same way as the CUT switch.

17 If SOLO-IN-PLACE (SIP) is not selected on the Master Module, pressing

the SOLO switch feeds the channel signal to the PFL bus and changes the central

monitoring over to the selectedcd channel without muting any other channels.

If SIP is selected, pressing the SOLO switch cuts all other inputs, unless they are

isolated by the SAFE switch. This switch may be internally set by jumpers to act

as a Solo safe, Master Mute safe or both. The factory default setting is both.

Pressing the SOLO switch on a channel that is set SOLO SAFE or BOTH SAFE

whilst SIP is selected will AFL the channel in stereo. AFL changes the monitoring

over to the selected channel without muting any other channels.

VCA Grouping (RS5508 only)

18 The VCA version of the console has 8 VCA GROUPS. Selection is by a

thumbwheel switch. Only I VCA group can be active on each channel (positions

I to 8) at any one time. See 'VCA Group/Output Group/Stereo Input Module' later

in this manual for a full description of the VCA system .

When the thumbwheel is set to the blank position, the VCA system is inactive, and

the VCA is electronically bypassed .
