Plena Mixer Amplifier | Installation and User Instructions | Description
An LED meter monitors the master output before the
zone selection. This signal is also present on the
headphone connector below the output meter. For
total reliability and ease of use, a limiter is integrated
into the output stage to restrict output if the user
applies too much signal.
