In this conversion mode, the MC-4 accepts
the incoming AES3 or AES11 signals with dif-
ferent sampling rates per stereo input. Due
to this, it is maybe useful also to be able to
select one of the stereo inputs as reference
clock for the internal SRCs!
This setting generally allows to receive an 8-channel AES3 or AES11 signal
with clock rates between 25.0kHz and 200.0kHz. The signal‘s audio format
will be converted into ADAT
TM
or ADAT
TM
/ SMUX2 /4, S/PDIF and AES3 simul-
taneously, as in the previous section described. Additionally to the format
conversion a SRC process is added.
The sampling rate of all outputs now depends on the clock rate of the refe-
rence clock signal, which is selected in the »REFERENCE« menu. The above
example shows »AES11« selected as clock reference.
In this mode, the following clock references are available for synchronizati-
on of the internal SRCs:
WCLK, 25.0kHz – 200.0kHz, SCLK 11.2896MHz + 12.288MHz
AES11, 25.0kHz – 200.0kHz (through separate input at the rear)
ADAT
TM
or ADAT
TM
/ SMUX2 /4, 25.0kHz – 200.0kHz
AES3 IN1– 4, every of the AES3 stereo inputs, 25.0kHz – 200.0kHz
32.0kHz –192.0kHz, internal clock oscillator
To activate a clock source enter the »REFERENCE« menu and press the
»SELECT« button repeatedly. When the external clock reference signal can
be locked by the internal PLL circuit, the blue LED »LOCK
1
« in the »STATUS«
menu will light constantly. The clock rate of the selected clock source is
then displayed in the »REF CLOCK IN« menu under »1« accordingly.

This setting generally allows to receive an 8-channel S/PDIF signal with clock
rates between 25.0kHz and 200.0kHz. The signal‘s audio format will be
converted into ADAT
TM
or ADAT
TM
/ SMUX2 /4 and AES3 simultaneously, as in
the previous section described. Additionally to the format conversion a SRC
process is added.
The sampling rate of all outputs now depends on the clock rate of the refe-
rence clock signal, which is selected in the »REFERENCE« menu. The above
example shows Word Clock (»WCLK«) selected as clock reference, which is
the default setting.
In this mode are the same clock references available for synchronization of
the internal SRCs as previously described.

Does the reference clock signal not
exceed 50.0kHz, both ADAT
TM
out-
puts transmit the same signal and
the MC-4 functions as ADAT
TM
signal splitter.
If the reference clock signal exceeds
50.0kHz, the ADAT
TM
output format will
be automatically changed to »SMUX2«
or »SMUX4«, depending on the reference
signal‘s clock rate. The corresponding SMUX
format of the ADAT
TM
outputs will be dis-
played in the »STATUS« menu.
