Signature DDA 1:6
1 Input, 6 Outputs, AES Distribution Amp

Features Description Specifications Downloads Ask a Question
  • 1 x AES input, 6 x AES outputs
  • AES can be re-normalised
  • AES can loop straight through un-normalised
  • Front panel headphone connection with level control
  • All I/O on XLR

The DDA 1:6 is a cost effective distribution amplifier for digital AES signals.  Via rear panel XLRs there is a single input and 6 outputs.

The output signals can pass straight through without any normalising.  This is useful if you need syncronisation to be maintained. There is also an option to re-normalise all of the output signals to ensure that all outputs are at the full digital level again.  It is important to realise that re-normalising a digital signal while often desirable, does cost one sample. 

A headphone monitoring position is also provided on the front panel via a 6.35mm stereo jack socket.  This allows monitoring of the incoming audio signal via a variable level pot.

LEDs indicate AES lock or if there is an AES error.

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.
