Description
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.
Features:
- 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
