Introduction

Congratulations on your purchase of the AES/EBU Interface from Spirit by Soundcraft. You are
about to enjoy one of the great features of the Digital 328 - Expandability.

The AES/EBU Interface is designed to meet the following requirements:

l As an 8 channel interface to a Digidesign 888 Interface.

l As an 8 channel Interface to any single / multiple AES/EBU source or destination.

The Interface is an external accesory for the Digital 328 and other forthcoming Spirit Digital consoles,
although it may also be used for other applications. The interface provides 4 stereo pairs (8 channels)
of digital AES/EBU which can be routed to and from either of the console TDIF ports.

Operation

Connect the TDIF cable from the Interface to the port required on the console. Select TDIF as the
port type from the Tape Port Select Menu on the Digital 328.

You will now be able to bring in the connections to the interface on Tape Returns 17-24 (Port A), or
25-32 (Port B). The outputs from the interface can be fed directly from the Mic/Line channels by
selecting T.SND DIR on the appropriate channel.

When T.SND DIR is not selected on any of the Mic/Line channels, the ports will be fed with Groups
1-8 sequentially.

Connection Leads

This unit should be connected to the 328 using a standard TDIF cable. These are available through
your Spirit dealer.

Note that the cable must be constructed using 110 ohm digital audio cable.

Front Panel

1 Professional/Consumer audio data format selection switch - when set to Pro mode, the

AES/EBU sample frequency flag is always Not indicated. When set to Consumer mode, the flag is
set to 48kHz, 44.1kHz, 32kHz or Other according to the status of the TDIF sample rate in the Tape.

2 TDIF-1 25-pin female D-type connector - This port is used to transfer the digital audio to and

from the Digital 328, or compatible hardware.

3 Input Error Code Map - This map on the front panel of the unit describes how the unit indicates

the following errors in the incoming AES/EBU datastream:

4 Channel Error Indication - Four sets of three error flag indicators - each set for one stereo AES

input.

5 Clear Error Switch - This will reset the error detection circuit - and clear any errors presently

indicated.

6 Power Indicator - this indicates that the unit is receiving power from the input on the rear panel.

Digital Audio Synchronisation

The interface has no internal clock source, and is always synchronised to the incoming TDIF clock signal.
The external device connected to the AES/EBU device must either be synchronised from the Digital 328
wordclock output, or from the interface AES/EBU output. It is not possible to synchronise the interface
from the AES input.
