Calrec Hydra2 AL5870

Calrec Hydra2 AL5870

2 x Mic/Line In with Splits (XLR)

The AL5870 provides 2 balanced mic/ line level analogue inputs to the Hydra2 network along with a pre-gain analogue 'split' output for each input in a 2 slot-wide module. The 2 Input connectors are female XLR, the 2 'split' outputs are male XLR.

The pre gain analogue split outputs are active, irrespective of the Hydra2 interface card status, as long as the I/O box is powered.

Front panel LEDs indicate audio signal presence for each input and split output, lighting green for signals above -60dBFS.

Each input also has front panel LED indicators which light red when 48V phantom power is on.

This module supports phantom power detection, allowing for power to the mic input to be controlled by the device being fed from the split output. This feature is enabled per input / split using PCB mounted DIP switches fitted to the card. When active, if +24V DC or greater is detected on a split output (i.e. phantom power is being fed by the device connected to the split), the card will automatically switch its own phantom power to the corresponding mic input. If phantom power has been switched in this way, the 48 V LED indicator will briefly blink off approximately every two seconds.

The standard modular I/O status LED flashes green once the card has booted and lights solid green once a connection between the card and the Hydra2 interface has been established.
