2 WCLK IN

OUT

The above BNC connector (IN) receives a Word Clock or so-called »Super

Clock« signal as master clock reference for the SRCs. The below BNC con-

nector (OUT) transmits a low-jitter Word Clock signal based on the internal

clock base or the selected external clock reference signal. If format con-

versions only are carried out, the WCLK output sends a Word Clock signal

extracted from the selected digital audio reference signal.

The impedances of both connectors are 75 Ω (BNC connectors, female).

3 ADAT

These two optical inputs receive digital audio multichannel signals incom-

pliance with the Alesis ADAT

format. Input »A« alone accepts ADAT

signals up to 50.0kHz. For receiving ADAT

signals with higher clock rates

up to 192.0kHz, both inputs »A« and »B« are used simultaneously (Toslink

connector, EIAJ standard).

4 AES3 IN + OUT CHAN 1– 8

This interface receives and transmits 8 channels of AES3 digital audio sig-

nals each in compliance with AES3 –1992 (R1997). Alternatively, the 8 inputs

can also be feeded with S/P-DIF digital audio signals aligned to IEC60958.

The input and output impedances are 110 Ω. The pin assignment of the

25pin D-Sub connector complies with Yamaha, AKAI, Mackie and others, too.

5 ADAT

OUT

These two optical outputs transmit digital audio multichannel signals in

compliance with the Alesis ADAT

format. Eight channel ADAT

with up

to 50.0kHz clock rate are sent to both optical outputs, enabling a signal

doubling. For transfering ADAT

signals with higher clock rates up to

192.0kHz, both outputs »A« and »B« are used to split the ADAT

signal, as

described on page 16, under »SMUX2 + SMUX4« (Toslink

connector, EIAJ

standard).

6 S/P-DIF IN/OUT

These interfaces function as receiver and transmitter for S/P-DIF digital

audio signals in compliance with the IEC 60958 standard. Their func-

tion depends on the selected operation mode, which is displayed on the

front panel. The impedances of all connectors are 75 Ω (Cinch connectors,

female).

7 MAINS IN, Power Switch + Power Inlet

This is the main switch for switching the device on and off. Be sure to

make all connections (especially the supplied power cable) properly before

turning on the switch. Heed the SAFETY INSTRUCTIONS at the beginning of

this manual.

Connect the supplied power cable here. Make sure that the power switch

is turned off before connecting the power cable to this inlet and to the

power outlet. Line voltages within the range of 90…260V with a frequen-

cies between 47...440Hz can be applied. The internal power supply will

automatically make all necessary adjustments.
