This setting allows to input a S/P-DIF digital audio signal between 32.0kHz
and 192.0kHz at the optical input. Its clock rate will be displayed in the status
menu »CLOCK
IN «. The S/P-DIF input signal will be regenerated and converted
into Word Clock, AES11 and S/P-DIF coaxial and transfered to the correspon-
ding outputs simultaneously.
A S/P-DIF digital audio input signal will be standardly output as S/P-DIF blank
frame signal for synchronization purposes at the optical and coaxial outputs.
Similarly, the digital audio data will be not transfered to the AES3/11 output,
but only the clock reference data.

There are also two further function options available when feeding in an
S/P-DIF optical signal: »HOLD« + »REF PASS«.
When pressing the SELECT key for a further time, you can activate the
»HOLD « function which leads to a fail-safe output of all outgoing signals.

When pressing the SELECT key again, you can activate the »REF PASS« func-
tion. This special function regenerates and transfers a S/P-DIF optical input
signal to the format-same output. In this case, the S/P-DIF output signal in-
cludes all digital audio data for further use within your studio set-up, while
the other outputs supplying phase-aligned clock reference signals.
S/P-DIF optical + REF PASS
When feeding in a S/P-DIF optical
digital audio reference signal and
using the REF PASS functionality, the digital
audio signal will be only available at the
format-same S/P-DIF coaxial/optical outputs.
There will be no digital audio format con-
version to the AES3/11 output! The AES3/11
output transmits the AES11 blank frame
signal only. *
While processing the S/P-DIF signal, the PLL
synthesizer circuit extracts the clock out of
the S/P-DIF signal, is re-generating it and is
supplying it to all WCLK outputs. The WCLK
output pairs can be multiplied individually
by using the CLK Multipliers as mentioned at
page 19.
*) If you need to convert the S/P-DIF format
into AES3, please use the MUTEC MC-1 or
MC-1.1. These converters are especially made
for AES3 to S/P-DIF, and vice versa, digital
audio format conversion.
