Unidirectional Format Conversion from:
S/P-DIF coaxial to AES3, AES3id, S/P-DIF optical + coaxial
17
This setting allows to convert an S/P-DIF coaxial source signal (see under
»AUDIO
IN«, »S/P-DIF co«) unidirectionally (see under »MODE«, »UNI-DIR«)
into AES3, AES3id, S/P-DIF optical and S/P-DIF coaxial simultaneously. The
sampling rate will be displayed in the »REF CLOCK IN« menu. The incoming
S/P-DIF coaxial signal will be re-clocked and transfered to the format-same
S/P-DIF coaxial output. Thus, the original input signal is not lost and available
for further use!
Under »REFERENCE« the »S/P-DIF co« option is selected automatically. Ple-
ase see the grey box on page 16 for more information.

This setting allows to convert an AES3 source signal (see under »AUDIO IN «,
»AES3«) unidirectionally (see under »MODE«, »UNI-DIR«) into AES3id,
S/P-DIF optical + coaxial 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, 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)
Inputs of AES3, AES3id, S/P-DIF op, S/P-DIF co, each 25.0kHz – 200.0kHz
32.0kHz –192.0kHz, internal clock oscillator
To activate a clock source enter the »REFERENCE« menu and press the »SE-
LECT« button repeatedly. When the external reference clock signal can be
locked by the internal PLL circuit, the first blue LED »LOCK« in the
»STATUS« menu will light constantly. The clock rate of the selected clock
source is then displayed in the »REF CLOCK
IN « menu with help of the first
LED row, marked with »1«.

Locking so-called
»Super Clocks«
Your MC-6 is able to lock to so-
called »Super Clock« (SCLK) reference
signals. These clock signals are used
preferably for older digidesign ProTools™
MX systems. Specified are only two clock
rates, 11.2896MHz + 12.288MHz which are
the x256 multiple of the Word Clock rates
44.1kHz and 48.0kHz.
When locking to one of these Super Clocks,
the rate will be inverted displayed in the
»REF CLOCK
IN« menu. Due to this, the LED
in front of the corresponding base clock
rate, that means Word Clock rate, does not
light while all other LEDs light (see exam-
ples below).
