ADDA 1 - Stereo Analogue to Digital and Digital to Analogue Converter

Signature Series/Digital Converters

The Signature ADDA 1 is a broadcast specification, bi-directional, analogue to digital, and digital to analogue audio converter.
The analogue inputs and outputs are available separately on balanced XLR connections, or unbalanced RCA phono connections.
The digital inputs and outputs are available separately in three formats:
- 3 pin XLRs using AES
- RCA phono plug using S/PDIF
- optical connectors using TOSlink
The digital output is 24 bit and can be selected to be from 44.1kHz to 192 kHz.
The DARS (Digital Audio Reference Signal) can also be input on a separate 3 pin XLR input, or via the word clock input on a BNC connection.

The front panel features a 6.35mm stereo jack socket for headphones monitoring, with a full size pot to adjust the volume level. A front panel screen shows current operation mode and allows configuration of all unit parameters.
Power is provided by an internal switch mode power supply, with a wide input range. There is also an input for external 12v DC power. The 12v DC input can be connected to the optional Signature PS1external DC Master Power Station, for situations where a redundant power supply is desirable.
