Description
Calrec Hydra2 AD5781
Calrec offers a range of fixed format analogue I/O units, with various quantities of inputs and outputs available via either XLR or EDAC connectors.
All fixed format analogue inputs accept mic and line level signals.
Input impedance is automatically switched dependent on the gain setting of each input.
The gain of each input can be controlled from -18 to +78dB remotely from any mixing console on the network that has been granted access.
The impedance can be set globally to changeover at +18, 20, 22 or 24dB of input gain.

Phantom power
Phantom power can be switched on or off to each mic / line input remotely from any mixing console on the network which has been granted access.

Analogue reference level
The analogue-to-digital, and digital-to-analogue conversion level is set globally across the Hydra2 network. The most common values used are +4dBU analogue = -20dBFS digital, and 0dBU analogue = -18dBFS digital.

* Ports are labelled 'L' & 'R', however all ports can be used as discrete and independent mono if required. In addition, any two ports, not just adjacent ones, can be paired together for stereo processing within mixing console DSP.
