radiators or spotlights! The free flow of air inside and around the unit must always be ensured.

Initial operation

Prior to the initial operation of the unit, the appliance, its accessories and packaging must be

inspected for any signs of physical damage that may have occurred during transit. If the unit has

been damaged mechanically or if liquids have been spilled inside the enclosure, the appliance may

not be connected to the mains or must be disconnected from the mains immediately! If the unit is

damaged, please do NOT return it to MUTEC GmbH, but notify your dealer and the shipping com-

pany immediately, otherwise claims for damage or replacement may not be granted.

If the device is left in a low-temperature environment for a long time and then is moved to a room-

temperature environment, condensation may occur on the inside and the exterior. To avoid short-

circuits and flashovers, be sure to wait one or two hours before putting the device into operation.

Power supply

The device contains a self-adapting wide-range power supply supporting the majority of global stan-

dard line voltages within a range of 90…250 V, with no need for making adjustments. Make sure that

your line-voltage source provides a supply voltage within the specified range. In addition, make sure

that the device is properly grounded via the local electric installation.

Please use the enclosed power cord (see packaging) to connect the unit to the mains. Switch the

unit off before you attempt to connect it to the mains. Connect the power cord to the unit, then

to a standard 3-pin mains outlet. To draw the power cord, never pull on the cable but on the mains

plug!

The unit must be grounded during operation!

For information on the power-inlet wiring, refer to the »Wiring of connectors« section in the

appendix. Disconnect the device from the mains when not using it for an extended period!

This symbol, an exclamation mark inside a triangle,

alerts you to important operating or safety instructions

INTRODUCTION

Thank you very much for purchasing MC-7, Word Clock Distribution Ampli-

fier and Audio Clock Converter, from MUTEC!

General Function Description

The MUTEC MC-7 is an extremely flexible, high-performance 8 channel

Word Clock distribution amplifier and audio clock converter.

The MC-7 distributes and converts Word Clock, AES3/11 and S/P-DIF signals.

An incoming reference signal passes latest audiophil-optimized PLL circuits,

to be distributed and output as low-jitter, high-quality clock signal, regard-

less of the condition of the reference signal. Thereby, connected audio

devices will benefit from the MC-7’s signal regeneration abilities, which

improve their sound qualities audibly.

Furthermore, the MC-7 functions as multiplier for the clock rate of the inco-

ming reference signal. Therefore, the outputs can be individually multiplied

by x1, x2, x4, which leads to a very wide range of possible output Word

Clock rates from 32.0kHz up to 768.0kHz. This enables e.g. the contempora-

neous output of an incoming 48.0kHz reference signal with 96.0kHz, 192.0

kHz and as so-called Digidesign Super Clock. A special ‘Ref Pass’ functionality

secures the availability of an incoming digital audio signal for further use.

For live or broadcast use, a special ‘Hold’ functionality can be activated

additionally. This function guarantees interruption-free output signal

supply in cases when the external reference is of insufficient quality or lost

completely. Thus, the MC-7 is predestined to be used as centralized clock

stabilizer and distributor, where reliable signal availability is a must.

Due to its synchronisation features and connection flexibility, the MC-7 of-

fers unique possibilities to provide interconnections between digital audio

devices on a reliable and useful basis. This all makes MC-7 for sure an uni-

que and outstanding digital audio clock distributor and converter enabling

to handle every clocking issue in your studio set-up with ease!

CONTROL ELEMENTS AND TERMINALS

MC-7 Front Panel

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 REFERENCE

This function menu allows to select all acceptable input reference signals

for distribution or conversion. Furthermore, every input reference is avail-

able with two additional options: the »HOLD« function and the »REF PASS«

function. See details in chapter OPERATING THE MC-7.

5 CLK MULTIPLIERS

This functional menu lets you determine the factor by which the basis clock

rate of the incoming reference signal is multiplied additionally. This setting

can be made individually for every Word Clock pair of outputs as well as for

the AES/EBU and S/P-DIF outputs.

6 STATUS

This menu indicates various signal statuses of the incoming reference or

digital audio signal.

7 CLOCK IN

This menu indicates the clock rate of the incoming reference signal. Audio

Clock rates between 32.0kHz and 192.0kHz can be analysed and displayed.

8 WCLK OUT 4

This pair of Word Clock outputs transfers either all standard Word Clock

rates as well as Word Clock x 256 for older Digidesign ProTools™ systems. Its

numbering is aligned to the functional menu »CLK MULTIPLIERS« on the front
