Kurzweil K2600 ADAT IO OPTION - RELEASE NOTES REV A User Manual

Part No. 910407, Rev. A
K2600 ADAT I/O Option User’s Guide / OS 4.1 Release Notes
This document explains how to use the K2600 ADAT Digital I/O Option (KADT26) and also provides release notes
for Version 4.1 of the K2600 Operating System. The ADAT Digital I/O Option requires version 4.1 or higher of the
K2600 Operating System.
The K2600 ADAT Digital I/O Option provides 8 channels of digital input and output in the ADAT Optical format.
An optical AES Out connector is also provided (AES In is available on the Sampling Option). This option must be
installed by a qualified Kurzweil service center.
Cable Connections
Use standard optical link cables (TOSlink) to make ADAT and AES connections. Although the format is different,
the same type of cable is used for each type of connection.
When you use ADAT In, the K2600's ADAT Out cable must also be connected to the sending device. The K2600
must be the “master,” and the other device(s) must "slave" to it. Output sample rate (and therefore input as well) is
fixed at 48 kHz.
Output Signal Routing
The output signal routing from the ADAT Option is as follows:
A Left -> ADAT channel 1
A Right -> ADAT channel 2
B Left -> ADAT channel 3
B Right -> ADAT channel 4
C Left -> ADAT channel 5
C Right -> ADAT channel 6
D Left -> ADAT channel 7
D Right -> ADAT channel 8
