1 »POWER«

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

2 »MENU«

Use this key to access the different menus.

3 »SELECT«

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

4 »MODE«

This menu allows to select the clock references for internal and external synchronization as well as the reference for external-

ly-referenced digital audio re-clocking. All three LED rows act in functional dependence.

5 »REFERENCE«

This menu allows to select the clock references for external synchronization and audio re-clocking.

6 »CLOCK

OUT«

Here, the basis clock rate for the Word Clock-, the AES3/11- and the S/P-DIF outputs can be selected, while the MC-3+USB

is running in the »INTERN« mode, or is locked to an external 1–10.0 MHz reference, or when a DSD/DoP conversion to PCM

audio is carried out.

7 »CLOCK

MULTIPLIERS«

This menu lets you determine the factor by which the basis clock rate is multiplied additionally. Settings can be made individu-

ally for every pair of Word Clock outputs (»1–2«) as well as for the AES3 (»4«) and S/P-DIF (»3«) outputs.

8 »STATUS«

This menu indicates various signal status of the incoming reference clock or digital audio signal.

AES/EBU & S/P-DIF Interconnections

When working with XLR-based AES3/-11 or RCA-based S/P-DIF audio signals at high sampling rates , well-shielded electrical

cables are mandatory to avoid increased radiation! Standard cables are normally useable for sampling rates up to 50.0kHz.

When interconnecting the optical S/P-DIF interfaces with plastic ﬁber cables, lengths of 10 meters should not be exceeded,

to ensure reliable transmission of your digital audio signals. Glass ﬁber cables may transfer data reliably even over greater

distances while keeping the signal’s performance on a much higher level than plastic ﬁbre cables can do during transmission!

Information

MUTEC offers optical cables of various lengths that have been speciﬁcally tested for the transmission of ADAT™ and S/P-DIF

signals. Ask your local dealer for such cables!
