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!

INSTALLATION

Content of the Box

The unit was packed carefully. Nevertheless we recommend to check the content directly after opening the package:

1 x MC-7 1 x Power cable 4 x Rubber feet 1 x Manual

Placing the Device

The unit should be set up as closely as possible to the devices to which it will be connected, so as to avoid excessive cable lengths. Use the 4 rubber feets enclosed with the appliance and stick them symmetrically on the bottom side of the unit to protect the enclosure and supporting surface from being damaged.

The device can be mounted into a standard 19“ rack and will require 1 unit. In this case, the rubber feet cannot be attached. Install the device so that one unit of rack space is left free both above and below the device to allow for sufficient ventilation! The mounting depth including the terminals is 160 mm/6.7“. Another 60 mm/2.4“ should be added for the required cables.

Additional slide-in rails on the rack inside are recommended for safe installation. This will also avoid long-term mechanical deformation of the housing.

The condition of the packaging material and the device should be checked carefully additionally. If there are any damages please refer to SAFETY INSTRUCTIONS, Initial Operation, and WARRANTY REGULATIONS.

Before installing the unit the section SAFETY INSTRUCTIONS located at the beginning of this manual

should be read carefully.

Never expose the device and accessories to rain, moisture,

direct sunlight, or excessive heat produced by radiators, heaters, or spot lights! Sufficient air circulation in the environment of the device must be ensured!

Wiring the Word Clock interfaces

To allow for the synchronization of signals, the interfaces of all devices involved must be properly connected to each other, so as to ensure a logical signal flow. Always be sure to connect the Word Clock output of the MC-7 to the corresponding input of the device you wish to synchronize. Cable lengths should be kept as short as possible to minimize signal losses and/or interferences!

For the transmission of Word Clock signals electrical, unsymmetrical cables with a resistance of 75 Ω and BNC connectors on both ends are used. Typi- cally, such cables are marked »RG-59U, RG59B/U«.

Additionally, you should make sure that the Word Clock inputs to be con nected to the MC-7’s outputs have a 75 Ω terminating resistor! Most Word Clock inputs allow for enabling/disabling the termination with a so-called »termination-switch«, which may be located on the outside or inside of the device.

For devices which have no termination of the Word Clock input, e.g. RME Hammerfall with Word Clock i/o, Alesis BRC or M-Audio ProFire Light bridge, you can use an additional BNC-T piece to terminate the input. Plug the T piece with its center connector into the input of the receiving device. Then, connect the cable coming from the MC-7’s Word Clock output to one of the lateral connectors, and the other connector of the BNC-T piece to a 75 Ω resistor forming the BNC termination.

Basically, you should avoid »looping through« Word Clock leads by means of passive BNC-T pieces to preserve the signal quality, as level drops will be the result. If there is no other way to wire your set-up, please make sure that all Word Clock inputs (except for the last device in the chain) have their terminations disabled! In a serial Word Clock chain only the last clock input should have a termination! Never connect more than three devices in series to one output!

It is imperative that the lengths

of all cables connected are largely

ensure that all devices will be synchronized in phase (exception: cable tolerances).

Please make sure that the cable used has a resistance of 75 specifications! If a cable with a different resistance is used, a dramatic deterioration of the signal quality can be the result! In this case, the perfect synchronization of all devices involved could be impaired.

We recommend using high-grade cables with a good shielding. A length of max. 10 meters (approx. 30 feets) should not be exceeded!

MUTEC offers optical cables of various lengths that have been specifically tested for the transmission of S/P-DIF signals. Ask your local dealer for those cables!

Wiring the AES/EBU and S/P-DIF Interfaces

Since some manufacturers offer optimized cables for the transmission of digital S/P-DIF and AES/EBU audio signals, it will be a good idea to ask your retailer for specific cables.

Especially when working with high AES/EBU clock rates well shielded

clock lines are imperative to avoid increased radiation! Standard cables are normally useable for clock rates up to 50.0kHz. Special shielded cable material should be used for transfer of higher clock rates.

MUTEC offers optical cables of various lengths that have been specifically tested for the transmission of S/P-DIF and ADAT™ signals (retailers and distributors only)!

Connect the AES/EBU interfaces with the help of balanced electrical cables equipped with XLR connectors on both ends. The specifications stipulate a specific cable resistance of 110 Ω (ask your retailer for a confirmation of this value when purchasing the cables).

Connect the coaxial S/P-DIF interface with the help of unbalanced electrical cables equipped with cinch connectors on both ends. The specifications stipulate a specific cable resistance of 75 Ω (ask your retailer for a confirma- tion of this value when purchasing the cables).

Connect the optical S/P-DIF interface with the help of Toshiba TOSLINK™ compliant optical fiber cables. Here, you can use both plastic and glass fiber-based cables. When using plastic fiber cables, lengths of 10 meters should not be exceeded, so as to ensure the reliable transmission of signals. Glass fiber cables can transfer data reliably even over greater distances.

OPERATING THE MC-7

REFERENCE + CLK MULTIPLIERS Menus

These both menus are offering access to the whole functionality of your MC-7.

The »REFERENCE« menu contains of two LED raws. With help of the first, left LED raw you select the input reference for distribution or signal conversion. The second LED raw within this menu signalizes special functionalities which can be added to the distribution or conversion process. Therefore both menus act together in different combinations.

The »CLK MULTIPLIERS« menus allow for adding clock rate multipliers individually to the 4 Word Clock output pairs as well as to the AES3/11 and S/P-DIF outputs. Their numberings are aligned to the output numbers.

The menus »STATUS« and »CLOCK IN« are for control of the MC-7‘s operation status only. They are not accessable for adjustments.

General Operation Procedure

The MC-7 menu is strictly organized aligned to generally usual handling procedures when inserting such a box into your studio set-up. So, you can split up all of the necessary adjustments in tow simple steps, which leads to the following three questions for the basic operation of your MC-7:

1) Which is my reference signal to be distributed → REFERENCE?

WCLK = Word Clock or so-called Super Clock

AES3/11 = AES3 or AES11

S/P-DIF co = S/P-DIF optical

S/P-DIF op = S/P-DIF coaxial

REFERENCE

2) Do I need increased output clock rates? → CLK MULTIPLIERS?

1 6 5 4 3 2

1 =

2 =

4 =

After these general decisions are made, your MC-7 is configured for optimal operation in your set-up! Due to the fact that the system monitors for useful function combinations, maloperation is not possible.

So, let‘s have a look to the individual functions on the next pages.

Locking so-called

»Super Clocks«

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

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 examples below).

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 information. The AES11, also know as ‚blank frame signal‘, does not carry any digital audio data, but only the reference clock information for synchronization.

This setting allows to input an AES3 digital audio signal or an AES11 re ference clock signal between 32.0kHz and 192.0kHz. Its clock rate will be displayed in the status menu »CLOCK IN«. The AES3/11 input signal will be regenerated and converted into Word Clock and S/P-DIF and transfered to the corresponding outputs simultaneously.

If an AES3 digital audio signal is feed in, it will be standardly output as AES11 reference clock signal. Similarly, the digital audio data will be not transfered to the S/P-DIF outputs, but only the clock reference data for synchronization purposes.

CLK MULTIPLIERS

With help of the clock multipliers (»CLK MULTIPLIERS«) you can add a clock rate multiplication factor to each pair of clock outputs. This is possible in any state of operation of your MC-7. The numbering of the multipliers is aligned to the output numbers. Select the prefered output with the MENU key and choose the needed multiplication factor by pressing the SELECT key accordingly. The factory default is set to x 1.

The above mentioned front panel view shows the following adjustments as example:

Word Clock output pair no. 1 is set to Word Clock output pair no. 2 is set to x 2 Word Clock output pair no. 3 is set to x 256 Word Clock output pair no. 4 is set to x 4 AES3/11 output no. 5 is set to x 4 S/P-DIF outputs nos. 6 are set to x 2

»CLK MULTIPLIERs« 1 – 4 For every Word Clock output pair, nos. 1 – 4, are 4 multipliers available:

1, x 2, x 4, x 256

The multiplication functions »x 1, x 2, x 4« multiply all available basis clocks up to the highest possible Word Clock rate of 768.0kHz (192.0kHz basis clock x

4).

The function »x 256« refers only to the basis clocks of 44.1kHz and 48.0kHz of every incoming reference clock signal to output the so-called Super Clock rates, necessary for older digidesign ProTools™ MX systems. If a reference signal with a different clock rate, like e.g. 96,0kHz or 176.4kHz, comes in, the system identifies the included base clock rate and sets the multiplier accordingly to output only 44.1kHz x 256 or 48.0kHz x 256. The factory default is set at x 1.

Generatable Clock Rates

For a better understanding of the efficiency of the MC-7‘s clock multiplier, please refer to the tables »Generatable Clock Rates« on pages 23-25. There you can see which clock rates and clock signals the MC-7 is able to convert and to output simultaneously.

»CLK MULTIPLIER« 5 For the AES3/11 output no. 5 are 3 multipliers available:

x 1, x 2, x 4

Due to the maximum possible AES3/11 clock frequency of 192.0kHz, the functions of these multipliers are depending on the basis clock rate of the incoming reference signal. The factory default is set at x 1.

Example 1 The incoming basis clock runs at 32.0kHz, 44.1kHz or 48.0kHz:

x 1: AES3/11 output runs at 32.0kHz, 44.1kHz or 48.0kHz x 2: AES3/11 output runs at 64.0kHz, 88.2kHz or 96.0kHz x 4: AES3/11 output runs at 128.0kHz, 176.4kHz or 192.0kHz

Example 2 The incoming basis clock runs at 88.2kHz or 96.0kHz:

x 1: AES3/11 output runs at 88.2kHz or 96.0kHz x 2: AES3/11 output runs at 176.4kHz or 192.0kHz x 4: AES3/11 output runs at 176.4kHz or 192.0kHz

Example 3 The incoming basis clock runs at 176.4kHz or 192.0kHz:

x 1: AES3/11 output runs at 176.4kHz or 192.0kHz x 2: AES3/11 output runs at 176.4kHz or 192.0kHz x 4: AES3/11 output runs at 176.4kHz or 192.0kHz

»CLK MULTIPLIER« 6 Both S/P-DIF outputs, optical and coaxial, transmit same clock rate settings. For the S/P-DIF output pair no. 6 are 3 multiply functions available:

x 1, x 2, x 4

Due to the maximum possible S/P-DIF clock frequency of 192.0kHz, the functions of these multipliers are depending on the basis clock rate of the incoming reference signal. The factory default is set at x 1.

Example 1 The incoming basis clock runs at 32.0kHz, 44.1kHz or 48.0kHz:

x 1: S/PDIF outputs run at 32.0kHz, 44.1kHz or 48.0kHz x 2: S/PDIF outputs run at 64.0kHz, 88.2kHz or 96.0kHz x 4: S/PDIF outputs run at 128.0kHz, 176.4kHz or 192.0kHz

When moving the jumper from position 2 to position 1, the input termination will be switched-off. Therefore, the MC-7 must be connected in a chain, in which a device with terminated input follows. Otherwise you need to use a BNC-T piece in combination with a 75 Ω BNC resistor for terminat- ing the MC-7’s input.
