SX-48 Sub-Systems 

The SX-48 consists of a number of sub-systems that are described below. 

Base Unit 

The Base Unit includes the metalwork chassis, the front panel, the Power Supply Unit, and the 

motherboard. 

System Boards 

Every SX-48 includes the following system boards: 

MADI 

The MADI board provides an industry standard interface carrying 56* channels of audio at up to 48 
kHz, or 28 channels at up to 96 kHz.  

*Note that only the first 48 channels can actually be used at 48 kHz, because the unit only supports 

that number of analog or AES digital channels. 

Sync 1 

The Sync 1 board provides interfaces for the following synchronization signals: 

Internal (Crystal), AES digital audio, Word Clock , video (PAL or NTSC) and TSCP (Fairlight’s Total 
Studio Connectivity Protocol). 

I/O Boards 

There are four types of I/O boards that can currently be fitted into the SX-48, in a variety of 
combinations. 

AI1 – Analog Input 

The AI1 board provides 8 analog inputs at +4 dBu. 

AO1 – Analog Output 

The AI1 board provides 8 analog outputs at +4 dBu. 

AO1M – Analog Output with Speaker Protection 

The AO1M board provides 8 analog outputs at +4 dBu. It also includes circuitry that prevents pops 
appearing at the outputs on power up and power down, and is therefore suitable for output to high 

power monitoring systems. 

AES1 – Digital I/O 

The AES1 board provides 8 inputs and 8 outputs in AES/EBU format.
