The Plena Universal Amplifier is a mono mixer amplifier with 4 input channels. Each channel has 3 possible input
connections and a direct XLR output. You can adjust volume and tone level for each channel. The 4 input channels
and the cascade input are mixed to one master signal. This master signal is available on the XLR and DIN output
(mic. level). Additional outputs are the tape out and cascade out.
All pre-amplifier channels and the master output can be monitored with a headphone.
