INTRODUCTION
Thank you very much for purchasing the MC-4, Digital Audio Format and
Sampling Rate Converter, from MUTEC!
General Function Description
The MC-4 is an extremely flexible, high-performance digital audio for-
mat and sampling rate converter for ADAT
TM
, AES3 and S/P-DIF. All digital
audio signals can be processed with 8 channels and sampling rates up to
192.0kHz, whereas unidirectional and bidirectional conversion modes are
available. Based on latest FPGA designs, the MC-4 achieves levels of perfor-
mance regarding its signal quality, unique flexibility, clocking features and
the 16 channel sampling rate conversion engine (SRC), which are outstan-
ding in today’s industry!
Various operation modes enable the use of the MC-4 in many studio set-
ups. Generally, incoming digital audio signals are converted to all three
audio formats simultaneously, with or without SRC functionality. The SRC
engine can be locked to Word Clock, AES11 and any digital audio input in
both, unidirectional and bidirectional operation modes.
Furthermore, the MC-4 offers an internal, low-jitter clock base with high
accuracy to which the SRCs can be locked to, if no external reference is
available. This enables to run the MC-4 in set-ups where no separate master
clock is available. Furthermore, in this operation mode the MC-4‘s Word
Clock output supplies a low-jitter reference clock signal which is of same
high accuracy as the internal clock base. This can be used e.g. as master
clock reference for the whole studio.
This all makes MC-4 for sure a unique and the most flexible digital audio
multichannel converter in a ½ 19“ case currently available in the market!
