The AMS8-2AE, similar in features and operation to the AMS8-2A, is a compact, two 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 AMS8-2AE has four digital audio inputs. 110 Ohm balanced inputs are on 3-pin pluggable screw terminal connectors and 75 Ohm unbalanced inputs are on BNC connectors. An internal switcher allows the operator to toggle between the two banks of four balanced and unbalanced inputs. A reference input for DARS is provided. This may be 110 Ohms, balanced, via a 3-pin pluggable screw terminal connector or 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.
