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. Three high quality magnetically screened speakers are used to provide high SPL audio reproduction with system limiting.
