INTRODUCTION

Thank you very much for purchasing the 

MC-1.1+, Digital Audio Format 

Converter, from MUTEC! 

General Function Description 

The MC-1.1+ is a multifunctional, high-performance digital audio format 
converter for AES3, AES3id and S/P-DIF. Using latest digital audio circuit-
ries and low-jitter PLLs, the MC-1.1+ enables to improve and re-stabilize 
incoming digital audio signals, while converting and splitting those to the 
corresponding outputs. all audio formats can be processed up to 192.0kHz. 

The MC-1.1+ helps you to interconnect devices which use different digital 
audio formats and incompatible interfaces. The format conversion process 
does not only the necessary electrical conversion but also a format conversi-
on of the reference signals in compliance with the specifications which are 
standardized by the Audio Engineering Society (AES) and the International 
Electrotechnical Commision (IEC).

Dual low-jitter PLL circuitries allow to run two signal paths independently for 
realtime bidirectional format conversions. Additionally, the MC-1.1+ provides 
two outputs for each digital audio format which enables the use as signal 
splitter or distribution amplifier.

Various uni- and bidirectional operation modes, 4-way signal splitting, 
SCMS processing or signal status detection make the use of the MC-1.1+ 
possible in a wide range of applications.

Features

AES/EBU3, AES3/EBUid and S/P-DIF optical/coaxial interfaces in one box. 
Uni- and bidirectional format conversions from 32.0kHz to 192.0kHz bet-
ween AES3/11 and S/P-DIF. 
Simultaneous format conversion to all output formats while allowing 
the original signal to pass through. 
Signal improvement by low-jitter audio PLLs. 
AES3/11, AES3id/11id and S/P-DIF optical/coaxial signal splitting. 
SCMS processing and status analyzing. 
NONE-PCM and DTS bitstream detections. 
Easy configurable. 
User‘s settings will be stored after switching-off. 
Rack space saving 1/2 19“ case allows for mounting two devices in one 
rack unit. 
Built-in international power supply.

Applications

Interconnection of consumer and professional digital audio devices. 
Realtime bi-directional signal transfer and format conversion between 
send/returns of digital mixing consoles and effect processors. 
Uni- or bi-directional interconnection of computer-based sound cards 
with professional digital audio equipment. 
AES3/AES11 and S/P-DIF signal splitting and distribution. 
Digital audio signal refreshing. 
SCMS coding of digial audio productions to protect those against illegal 
copying. 
S/P-DIF optical/coaxial status analyzing.
