Chapter 1: Stage Rack Overview
Stage Rack Features
The Stage Rack provides the primary audio connections to the
Digidesign VENUE system, handling mic/line source input,
and output to monitors and the main speaker system.
The Stage Rack has a flexible I/O scheme that offers the following capacity:
• Up to 48 inputs with remotely controllable mic preamps
and individually selectable Phantom Power
• Up to 48 outputs
Redundant Digital Snake An optional redundant Digital Snake
cable can be run between the FOH Rack and the Stage Rack.
This redundant Snake automatically takes over communication if the first Snake cable fails.
Operational Requirements
Temperature and Ventilation
The Stage Rack unit should be operated away from heat
sources and with adequate ventilation.
Components
Storage
Included Components
The Stage Rack unit should be stored and transported at temperatures not lower than 0 degrees F (–18 degrees C) and not
exceeding 140 degrees F (60 degrees C).
The following components are included in a base Stage Rack
configuration:
• Stage Rack unit with 6 SRI (Stage Rack Input) cards and
1 SRO (Stage Rack Output) card
• AC power cord
Additional Required Components
Operation
The Stage Rack unit should be operated at temperatures not
lower than 40 degrees F (4 degrees C) and not exceeding
115 degrees F (46 degrees C).
Water and Moisture
The following component must be purchased separately:
• Digital Snake cable: this cable can be purchased directly
from Digidesign or assembled by your preferred vendor
using the following cable recommendations.
• Connector (x4): BNC male
The Stage Rack unit should be operated away from sources of
direct moisture and should be kept clear of liquids that might
spill into the units. If condensation is present on the unit,
leave the unit to dry in ambient air for at least one hour before
powering the unit on.
• Cable Type: Coaxial, 75 ohm
• Max Length: 250 ft (76 m) Belden 1885A or
500 ft (152 m) Belden 1694A
Expansion Options
Expanded Stage Rack I/O Each Stage Rack can be expanded
with up to a total of 6 input cards and 6 output cards, for a total of up to 48 inputs or up to 48 outputs.
Additional Stage Rack A second Stage Rack can be added to a
D-Show system, for a total of up to 96 inputs or up to 96 outputs. (A second Stage Rack requires an additional Digital
Snake card be installed in the FOH Rack.)
Cleaning and Maintenance
If you need to clean the surface of the Stage Rack unit, use a
dry cloth. Do not apply any cleaning solutions, spray cleaners,
or abrasives to the surface.
Power Connections
Each power supply in the Stage Rack requires its own power
connection. Each power supply is auto voltage-selecting
(100V to 240V). A modular IEC power cable is provided for
each power supply in the unit.

The Stage Rack I/O section consists of 12 slots that accept
modular input cards or output cards. The first 6 slots (A–F) of
the Stage Rack accept input cards (such as SRI cards) only. The
last 6 slots (G–M) accept output cards (such as SRO cards)
only.

Chapter 2: Connecting the Stage Rack
Connecting the Stage Rack to the FOH Rack
The Stage Rack is connected to the FOH Rack with the Digital Snake cable (available separately from Digidesign).
To connect the Stage Rack and the FOH Rack:
1 On the Stage Rack, connect the Digital Snake cable lead with the white connector sleeve to the Snake 1 In port (this port label
is outlined in white), and the Digital Snake cable lead with the red connector sleeve to the Snake 1 Out port.
2 On the FOH Rack, connect the Digital Snake cable lead with the white connector sleeve to the to the Snake 1 Out port (this
port label is outlined in white), and the Digital Snake cable lead with the red connector sleeve to the Snake 1 In port.
3 If you are using a second, redundant Digital Snake, connect it to the Snake 2 ports on each unit in the same manner, matching
the white connector sleeves to the ports whose labels are outlined in white.
When the units are turned on, the Snake Signal LEDs (marked “Sig”) on the FOH Rack and the Stage Rack light solid to indicate
the Snake connection. If the Snake Signal LEDs flash, a Snake connection has not been established.
If there are problems with the Snake connection, double check that all the BNC connectors are fully secured. If the
problem persists, try reversing the red and white connectors on one end.

◆ Connect analog line-level output destinations (such as
power amplifiers, crossovers, or speakers) to any of the output
connectors on any SRO Card.
◆
Applying Phantom Power to Stage Rack Inputs
Each SRI Card input has available standard 48V phantom
power.
Before connecting or disconnecting a microphone on any
Stage Rack Input, make sure phantom power is turned off
for that input, and the channel is muted.
To apply phantom power to a Stage Rack input source:
1 Target a channel in the ACS section of the control surface.
2 Press the +48V switch in the ACS Input section.
The corresponding channel’s “+48V” LED on the Stage Rack
Input Card lights to indicate phantom power is on.
