The Plena Mixer Amplifier is a high performance, professional public address unit for mixing up to six separate microphone/line signals, and any one of three separate music signals.
The volume of each microphone/line signal can be individually adjusted to obtain the required mix; the mixed output is controlled via the master volume control and separate high/low tone controls. The unit is easy to use, and provides a crisp call or clear music. The amplifier also has enhanced features such as ducking level control, priority, labelling, and setting indicators.
All Microphone/line inputs can be switched between microphone level and line level sensitivity. The inputs are balanced but can also be used unbalanced. Phantom power can be selected via a DIP switch to provide power to condenser microphones. Input channels 1 and 2 can take priority over all other microphone and music inputs:
- Input 1 can be activated by contact closure on a PTT (push to talk). A chime can be configured to precede an announcement.
- Input 2 can be switched automatically if a signal is available at the input, for example. if someone speaks into the microphone (VOX activation).
A telephone/100 V emergency input with VOX activation is also provided for easy integration with another PA system or a telephone paging system. It has its own volume control and overrides all other inputs, including the call station and inputs 1 and 2.
