1 »WCLK OUT 1– 3«
These 3 pairs of Word Clock outputs transfer all standard Word Clock rates and Word Clock
×
256 for older digidesign Pro-
Tools™ systems. Their numbering is aligned to the apropriate menus on the front panel. The individual BNC connectors are
pairwise marked as »A« and »B«, which allows for, e.g. simple documentation of the connected devices. The impedances of all
connectors are 75 Ω (BNC connectors, female).
2 »S/P-DIF OUT 4«
These two S/P-DIF outputs, available as optical and coaxial interfaces, transmit an optical (»OP«) and unbalanced electrical
(»CO«) S/P-DIF digital audio or blank frame signal in compliance with the IEC 60958 standard. The coaxial interface impedance
is 75 Ω. (RCA connector), the optical interface offers a Toshiba Toslink
TM
connector, EIAJ standard. Its numbering is aligned to
the apropriate menu on the front panel.
3 »AES3/11 OUT 5«
This AES/EBU output transmits a transformer-balanced electrical digital audio or blank-frame signal in compliance with AES3-
1997 (revision of 1992) or AES11-2003 (revision of 1997). Its numbering is aligned to the apropriate menu on the front panel.
The output impedance is 110 Ω (XLR connector, male).
4 »AES3/11 IN«
This AES/EBU input receives a balanced electrical digital audio or blank-frame signal in compliance with AES3-1997 (revision of
1992) or AES11-2003 (revision of 1997). The input impedance is 110 Ω (XLR connector, female).
5 »S/P-DIF IN«
These two S/P-DIF inputs, available with optical (»OP«) and coaxial (»CO«) interfaces, receive an optical and an unbalanced
electrical S/P-DIF digital audio or blank frame signal in compliance with the IEC 60958 standard. The coaxial interface imped-
ance is 75 Ω. (RCA connector), the optical interface offers a Toshiba Toslink
TM
connector, EIAJ standard.
6 »WCLK + 10.0M IN«
This input can receive a Word Clock, a Word Clock
×
256 as well as a 10.0 MHz reference clock signal. The impedance of the
connector is 75 Ω (BNC connector, female).
8 »MAINS IN«, Power Mains connector (IEC)
This is the main switch for switching the device on and off. Connect the supplied IEC power cable to the device‘s mains con-
nector. Make sure that the power switch is turned off before connecting the device to your power source finally. Line voltages
within the range of 90…260 V with a frequency of 50 or 60 Hz can be applied. The internal power supply will automatically
make all necessary adjustments.
