Ward-Beck AMS8-1AAE/75 Multichannel Audio Monitor
The AMS8-1AAE/75, similar in features and operation to the AMS8-1AA/75, is a compact, one rack-unit, aural and visual monitor designed to handle multi-channel format audio signals. Eight PPM/VU LED bargraphs display signal activity, while a sophisticated multi-speaker system allows operators to listen, with great clarity, to the signal being monitored. The AMS8-1AAE/ has four 75 Ohm, unbalanced digital audio inputs and Four analog stereo inputs on 3 pin pluggable connectors. An internal switcher allows the operator to toggle between the digital and analog inputs. A reference input for DARS is provided (75 Ohms, unbalanced) via a BNC connector. The unit is equipped with a Dolby Decoder card. With the Dolby decoder card added, the four digital audio inputs may be PCM, Dolby E or Dolby AC-3 or any combination of the three signal formats. The auto recognition feature determines whether the signal is Dolby encoded and routes it automatically to the Dolby decoder. When a Dolby encoded signal is being monitored the decoded AES signal group is presented on the four output connectors (75 or 110 Ohm) in the following sequence: OUT 1 - L and R, OUT 2 - C and LFE, OUT 3 - LS and RS, OUT 4 (if present)- LT and RT. Additionally, an analog copy of the L, R, C, LFE, LS and RS signals is provided on the AUX DB25 multi-pin connector.
Metadata extracted from the Dolby signal is provided on the DB9 connector on the rear panel.
