Kurzweil K2600 ADAT IO OPTION - RELEASE NOTES REV A, K2600, KADT26 User Manual

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

New Objects included with the ADAT Option

New Objects included with the ADAT Option

K26ADAT.K26 (included on disk with the ADAT option) provides two programs and a KDFX studio for use with
the ADAT option. These objects are described below. Use Disk Mode to load the K26ADAT.K26 file.

Remember that in order to use the ADAT inputs, the source must be synchronized to the K2600. In other words,
the K2600 must provide the master clock signal. This is accomplished by connecting the K2600's ADAT output to
the source's ADAT input.

Program 200: ADAT in 8 mono processes the 8 channels from your ADAT input individually. Press and hold a key,

and use the 8 sliders (A through H) to mix the 8 channels. Use the ModWheel to add Aux reverb to all 8 channels.
Use SW2 to enable Insert FX. If you get tired of holding the key down, you can edit the program's 8 layers and turn
on IgnRel on the Layer page.

Program 201: ADAT in 4 stereo processes the 8 channels from your ADAT input as 4 stereo pairs. Press and hold a

key, then use the 4 sliders (A through D) to mix the 4 stereo signals. Use the other 4 sliders (E through H) to adjust
the Insert FX wet/dry balance. Use the ModWheel to add Aux reverb to all 8 channels. Use SW2 to change Aux
reverb time.

The table below summarizes controller assignments in these two programs.
