Stage Box; Stage Box Description; Card Function Overview - SoundCraft VI6 User Manual

STAGE BOX

The Stage Box contains 12 Slots for 6U-high Audio I/O Cards, a GPIO/LED Card and the MADI HD Card
which contains the Stage Box-to-Local Rack connection.
Slots are labelled from left to right A-L, and the connectors on the cards are numbered from top to bottom
1-8. These labelling references are used by the patching system (see chapter 11) when the user wishes to
patch the connectors to input channels or output busses.
The primary power supplies and the ventilation monitoring connector can be found on the rear panel.

Stage Box Description

Primary power supply
The primary power supply connects directly to the IEC inlet and provides a full range ac inlet, converting
100V to 240V ac to 24V dc. The Stage box can hold up to two power supplies, providing redundancy for
those that require it.
Audio I/O Cards
The following cards are supported.
8 X Mic/Line Input cards each providing eight electronically balanced Mic/Line Input channels,
each with digitally-controlled analogue gain, a 20dB pad, a 80Hz low-cut filter, and phantom
power.
4 X Line Output cards, each providing eight line output channels.
Optional Cards
AES Input card, providing 8 AES input channels (replaces 1 Mic/Line Input card).
AES Output card, providing 8 AES output channels (replaces 1 Mic/Line Output card).

Card Function Overview

Input card
Input cards handle 8 x mic amp, phantom power, pad, analogue low pass filter, phase reverse and A to D.
The card has an internal ID, which indicates whether it is input or output and analogue or digital. This
means that the system can automatically recognise if the card configuration has been changed.
Output Card
Output cards handle 8 x D to A. The card has a set of relays, which will mute the outputs if the power fails.
The module type is identified by the internal ID of the module.
Normally 4 output cards are fitted, giving 32 outputs, however, more cards, up to a maximum of 8 cards
giving 64 outputs, can be fitted if input cards are removed.
LED/GPIO/Status card.
Handles GPIO, which is controlled remotely from the Control Surface. The inputs are on opto-isolators and
the outputs are open collector transistor outputs. The card also has status indicators for power rails, clock
status and IO, and a RECONFIG button which must be pressed if the card configuration has been changed.
MADI HD link card
This card provides audio and control connection with the Local Rack via MADI. The corresponding MADI
card in the Local Rack transmits the clock for the Stagebox down the MADI stream. The second input on
the card can be used to increase the sample rate to 96KHz, provide a redundant connection to the Local
rack or to connect to a second system if two consoles are to be used for a monitor/FOH configuration. The
