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, regardless 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 contemporaneous 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 unique and outstanding digital audio clock distributor and converter enabling to handle every clocking issue in your studio set-up with ease!

MC-7 Features

Distributes and converts Word Clock, AES3/11 and S/PDIF Extracts and re-generates clock signals out of digital audio signals Improves audio quality of connected devices Handles Word Clock rates from 32.0kHz up to 192.0kHz/768.0kHz Supports so-called Super Clocks for older Digidesign ProTools systems Offers 4 inputs and 11 outputs in total Protects from reference signal dropouts Supplies interruption-free output signals AES11, Grade 1, internal reference clock (0.5ppm) Easy to configure Compact case size fits in every studio set-up Built-in international power supply

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 available 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 panel. For adjusting these outputs see chapter OPERATING THE MC-7.
