CONTROL ELEMENTS AND TERMINALS

MC-8 + MC-8.1 Front Panel 

(both panels are equal)

1 

POWER

This red LED lights up when the unit is switched on with the rear panel 
POWER switch.

2 

MENU 

This key selects one of the available function menus.

3

 SELECT 

Use this key to select a function within a specific function menu.

4

 MODE 

This menu allows to select all conversion and splitting functions with or 
without SRC functionality in a logical manner.

5

 REFERENCE 

This function menu allows to select the master clock reference for synchro-
nization of the SRCs.

6

 STATUS 

This menu indicates various signal statuses of the incoming clock reference 
for the SRCs. 

7

 REF CLOCK 

IN

This menu indicates the clock rate of the selected reference clock signal.

8

 AES11 

IN

This input receives a balanced digital AES11 blank frame signal in com-
pliance with AES11–1997/2003 as master clock reference for the SRCs.  
Alternatively, an AES3 digital audio signal in compliance with AES3 –1992 
(R1997) or a S/PDIF digital audio signal aligned to IEC60958 can be input as 
well. The input impedance is 110 

Ω

 (XLR connector, female). 

9

 WCLK IN + OUT 

The above BNC connector (IN) receives a Word Clock or so-called »Su-
per Clock« signal as master clock reference for the SRCs. The below BNC 
connector (OUT) transmits an low-jitter Word Clock signal based on the 
internal clock basis or the selected external clock reference signal. The im-
pedances of both connectors are 75 

Ω

 (BNC connectors, female).

9

Refer to the OPERATIONS chapter for more 
information.

Differences between AES3 and AES11

Both standards, published by the Audio 
Engineering Society (AES), are based on the 
same interface, commonly called as AES/EBU 
interface which uses XLR connectors.

The AES3 standard carries both, the digital 
audio data and the reference clock informa-
tion. The AES11, also known as ‚blank frame 
signal‘, does not carry any digital audio 
data, but only the reference clock informati-
on for synchronization.
