Plena Mixer Amplifier | Installation and User Instructions | Description en | 8

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.
