HYDRA2 ANALOGUE OUTPUT SPECS
Digital - Analogue
Conversion
24 Bit
Output Balance
Electronically balanced. 20Hz to 20KHz, better than -35dB, typically -45dB
Output Impedance
<40 Ohms
Distortion
-1dBFS @ 1kHz - Better than 0.006%
-20dBFS @ 1kHz - Better than 0.003%
-60 dBFS @ 1kHz - Better than 0.3%
Frequency Response
20Hz to 20kHz +/- 0.25dB
Notes Analogue output for 0dBFS matches input setting into >1kOhms (+24dBu max into 600 Ohms)
Digital to Digital
(AES3) Distortion
-1dBFS, 20Hz to 10kHz - Better than 0.0001%
Digital to Digital
(AES3 with SRC) Distortion
-1dBFS, 20Hz to 10kHz - Better than 0.0002%
Frequency Response
(Analogue Input to Output)
20Hz to 20kHz +/- 0.5dB

* Note: These latency figures are for a system with a single Router/DSP core rack. Add 2 samples for each input, and 2 samples for
each output, for each additional core rack in the relevant part of the signal path.
