The AMS8-1AAM/75, similar in features and as the AMS8-1AM, 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 AMS8-1AAM/75 has four 75 Ohm, unbalanced AES digital audio inputs on BNC connectors and four analog streo inputs on 3-pin screw terminal pluggable connectors. Four AES output signals that are copies of the input signals are provided on the rear panel on BNC connectors. A reference input for DARS is provided on a 75 Ohm, unbalanced BNC connector. The AMS8-1AAM/75 is equipped with a Ward-Beck demux module capable of handling both SD and HD SDI signals with embedded audio. The demux module provides a re-clocked copy of the input digital video signal as well as a copy of the AES group that is selected for monitoring. The unit provides an analog stereo output that is a copy of the signal being fed to the integral speakers. This stereo output may be configured to follow the front panel speaker level control or to be a fixed line level output. The SERIAL COMM DB9 connector includes GPI and GPO inputs that may be used for tally and external control functions.
The versatile AMS8 series monitors may be field configured to suit the monitoring needs of a particular operation or location, using a combination of the eight segment LED dot-matrix readout, the eight lighted pushbuttons and the two rotary shaft encoders with integral pushbutton switches. Ward-Beck has developed an intuitive scheme to ease programming of the AMS8 series monitors. Features that can be readily programmed to assist in monitoring include: creating preset monitoring configuration, creating an infinitely variable proportional stereo mix-down of multiple audio channels, providing global control for monitoring and enabling voice-over on Dolby signals.
