OPERATING THE MC-6

MODE / AUDIO IN

REFERENCE Menus

These both menus are offering access to the whole functionality of the

MC-6.

The »MODE« menu in combination with the »AUDIO

IN« menu are offering

generally all available conversion modes together with the corresponding

digital audio formats. The system makes sure that only useful combinations

of conversion modes and proper audio formats are accessable. Therefore

both menus act together in different combinations.

The REFERENCE menu supplies all necessary synchronization options for the

corresponding conversions modes and the use of the internal sampling rate

converters (SRC). Due to the fact that both menus act together, regardless

if only format conversions or format and sampling rate conversions need

to be done, we will have a look on both together for any function which is

being described in the following.

The menus »STATUS« and »REF CLOCK

IN« are for control of the MC-6‘s

operation status only. They are not accessable for adjustments.

General Operation Procedure

The MC-6 menu is strictly organized aligned to generally usual handling

procedures when inserting such a box into your studio‘s data stream. So,

you can split up all of the necessary adjustments in three steps, which leads

to the following three questions for the basic operation of your MC-4:

1) What kind of conversion should be executed → MODE?

2) Which digital audio format(s) should be involved as source(s) → AUDIO

IN?

3) Which clock source do I need for my prefered operation → REFERENCE?

After these general decisions are made, your MC-6 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.

X-SRC = crosswise conversion between two formats and clock rates

BI-DIR = bidirectional conversion, between two formats only

UNI-DIR = unidirectional conversion, from one format to all others

SRC = above mentioned conversions with SRC

MODE

AES3 = AES3 between 25.0kHz and 200.0kHz

S/P-DIF op = S/P-DIF optical between 25.0kHz and 200.0kHz

AES3id = AES3id between 25.0kHz and 200.0kHz

S/P-DIF co = S/P-DIF coaxial between 25.0kHz and 200.0kHz

WCLK

Continuous Clock Supply

When setting up your MC-6 for the

first time, you will recognize that

within the »REF CLOCK

« menu the LED at

»44.1«, under »1« lights constantly. This is

due to the MC-6‘s continuous clock supply

function.

When no input signal is available, the MC-6

supplies at all digital audio outputs blank

frame signals, the Word Clock output carries

a corresponding Word Clock reference

signal. Thus, connected devices receive

immediately valid clock signals at their ap-

propriate inputs after starting up the whole

studio set-up. The initial clock rate of all

outputs is 44.1kHz.

When loosing the external clock reference

signal during operation, the MC-6‘s PLL

synthesizer lock the internal reference clock

oscillator on the clock rate which is nearest

to the lost one to provide stable reference

signals to the connected devices.
