Input levels are shown on 4 high-resolution, tri-colour bar graph meters with user adjustable colour transition points & peak-hold facility. Six standard user selectable scales & ballistics are also provided.
Analogue input and output levels can be independently adjusted. The audio source feeding the speakers is provided as a line output and to a headphone front panel socket.
High quality magnetically screened speakers are used to provide high SPL audio reproduction with system limiting.
This monitor also provides alarm facilities for audio over/ under level, sustained anti-phase and video loss.
An RS232 port provides remote control of all switch and alarm functions..
