7.1 Level Metering
The Telos Two includes two LED dual level meters. As is customary with digital
equipment these are peak reading meters with the topmost segment representing
0dBfs (digital 0). The following block diagram indicates where the metering takes
place. Note that all metering occurs in the digital domain. The metering is designed
so that the highest peak reading persists for a few seconds to aid in perceiving short
peaks. As with any digital system there is no level beyond 0dBfs and you must not
attempt to exceed that level or severe distortion will result.
