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.

Signature Series Standard Features

19" Rack Mount Ears
A Signature unit can rack mount in a 1U 19” rack, regardless of the size of the unit.  Rack ears are included as standard with every unit.

Front Or Rear Mounting
A Signature unit can be rack mounted via the front panel or if it is more convenient, via the rear panel by simply swapping the rack ears over.

Side Wings For Flat Surface Mounting
A Signature unit has side wings with mounting holes at the top and bottom, allowing flush fixing from above OR underneath.

Internal Switch Mode AC Power Supply
A Signature unit has an internal switch mode AC power supply, allowing worldwide power connections from 100-240v via an IEC socket.

12V DC Power Connection
All Signature units (except PS1) have a 4 pin XLR ±12V DC  socket for connection to the PS1 Power Station.  This can act as the primary or backup power source.

Quick Find Manual
A Signature unit has a QR code attached.  This can be scanned to simply and quickly locate the manual and technical information.
