3.3 Audio Inputs / Outputs

Analog Audio:

2channel analog XLR inputs and outputs. These XLR connectors are the

balanced analog audio inputs and outputs. Pin 2 is hot (+), pin 3 is cold

(-), and pin 1 is ground.

Digital Audio: 4 channel digital XLR inputs and outputs. Transformer balanced

AES/EBU input and output. Pin 2 is hot (+), pin 3 is cold (-), and

pin 1 is ground.

Audio Expansion1: Expansion Card Slot holds one of the following

A- 4 Channels AES / EBU

B- 2 Channels analog audio

Audio Expansion2: Expansion Card Slot holds one of the following

A- 4 Channels AES / EBU

B- 2 Channels analog audio

3.4 9 Pin Connectors

GPIO: General Purpose inputs and outputs

RS-422-1: Primary serial interface connector to the V1. Connector 1 should be

connected to your edit controller or workstation, while connector 2

is used to connect the optional RCV2 external remote control from

Doremi Labs, Inc.

RS-422-2/ Midi + Biphase:

If all 9 jumpers on J34 are set to the RS422 position, this connector

will be used as a second RS422 port (this is the default setting when the

unit is shipped). If all 9 jumpers on J34 are set to MIDI+BP position, this

connector will be used as a MIDI I/O and Biphase input with a +5V

supply.

3.5 Ethernet Connector

Ethernet: RJ45 connector 100BaseT

3.6 Time Code

Balanced TRS 1/4" input and output connectors for LTC time code. The V1 time code input

accepts balanced signals (tip hot, ring cold & sleeve is ground). If you are feeding an unbalanced

signal to it, both ring and sleeve should be connected to GND. You can use an unbalanced jack

(tip and sleeve) on the time code input of the V1. The V1 time code output is a balanced signal

(tip hot, ring cold & sleeve is ground). If you are feeding it to an unbalanced input, ring should

not be connected to anything. You cannot use an unbalanced jack (tip and sleeve) on the time

code output of the V1. If you connect time code from one V1 to another the cable should be

balanced on both ends.
