Crane AR2 Automated Audio Router

The Crane AR2 is a 19" / 1-U automated two channel balanced stereo router with manual override. The selected input pair is available as three independent stereo outputs. Output is monitored for audio presence which can be selected to switch to the secondary input or vice-versa during failure. Indication of active primary and secondary inputs are constantly displayed and the selected pair can be programmed to default to the stereo 20 point, 1 dB resolution peak programme meter. The selected pair is also monitored for out-of-phase content. Apart from the ppm, all displays as well as selection buttons are available for remote display/operation. Input gain is adjustable on four multi-turn trimming potentiometers on the front panel. Internal calibration is available for ppm gain as well as for audio detection level.
