Overview
The Plena PLE-2MA120-EU and PLE-2MA240-EU are professional public address mixer amplifiers designed to simplify complex audio management. With features like adjustable priority, voice activation, and music input management, these amplifiers ensure clear and reliable audio for a variety of environments. They are ideal for applications that require both background music and voice announcements, such as retail spaces, conference rooms, and public venues.
Functions
Microphone and Line Inputs:
- Balanced Inputs: The six microphone/line inputs can be configured for either microphone or line level sensitivity. Phantom power can be applied for condenser microphones.
-
Priority Inputs:
- Input 1: Can be activated with a push-to-talk (PTT) contact, with an optional 2-tone chime.
- Input 2: Automatically activates with signal input (VOX activation), ensuring smooth transitions for voice announcements.
- Priority settings allow attenuation or mute of non-priority inputs for talk-over or voice-over functions.
- Speech Filters: Enhance announcement clarity by filtering low frequencies and harsh high frequencies.
Music Inputs:
- Separate Volume Control: Three music inputs with their own volume controls and input selectors.
- Optimized Tone Controls: Adjust tone separately for music and mic/line inputs, ensuring the best sound quality for both speech and music.
Personalized Settings:
- Detachable Labels: Users can label inputs, music sources, and zones for easy identification.
- Preset Control Pins: Colored pins allow users to set controls to specific levels for different configurations, making it easy to switch between settings for various uses.
Tone Controls:
- Mic/Line Tone Control: Boosts vocal warmth while reducing rumble and harshness.
- Music Tone Control: Enhances bass and cuts rumble, providing better music reproduction.
- Special Contour: Adjusts frequencies to address real-world sound system challenges.
Emergency and Call Station Inputs:
- Emergency Override: 100 V and telephone emergency inputs with VOX activation.
- Call Station Integration: The call station input has priority, and announcements can be directed to zones as needed.
Zone Control:
- Two Zones: Allows for independent control of music and announcements in two different areas. Music can be turned on or off in each zone.
- Flexible Routing: Announcements from microphone inputs or the telephone input can be routed to both zones, with the ability to prioritize specific zones.
Output Monitoring:
- LED VU Meter: Monitors master output levels.
- Headphone Output: Allows for pre-zone monitoring of output before it’s sent to the zones.
- Limiter: Ensures the output does not exceed a safe level, preventing distortion or speaker damage.
