Communications Systems | PLE‑1MAxx0‑EU Plena Mixer AmplifierPLE‑1MAxx0‑EU Plena Mixer Amplifierwww.boschsecurity.com u 4 microphone/line inputs, plus 3 music source inputs u 100 V and telephone input with priority & VOX u Announcement only output, 3-wire volume override u Voice-activated emergency override u Wide range of power (30, 60 and 120 Watts) These Plena mixer amplifiers are high performance, When one or both inputs are configured to have professional public address units with modern state of priority, the amount of attenuation (reduction) of the the art features. They are easy to use, taking the cinch inputs, can be set between ‑2 dB (little complexity away from the user and putting it where it attenuation) or -∞ dB (mute). This provides a talk-over belongs, inside the equipment. Providing a crisp call or or voice-over function. Input channels 1 and 2 also clear music is as easy as turning on the radio. feature selectable speech filters to enhance the clarity The amplifier is also surprisingly affordable, without of announcements. sacrificing features such as ducking, priority and Music inputs flexibility. Separate music inputs are available with their own Functions input selector and volume control. The user can choose a music source like a CD player or radio (like Microphone and line inputs the PLN-DVDT), and set the level of music. All Mic/line inputs can be switched between microphone level and line level sensitivity. The inputs Personalized settings More unique features are available such as detachable are balanced but can be used unbalanced. Phantom labels where the user can write the names for inputs, power can be switched on to provide power to music sources and zones. These labels can then be condenser microphones. mounted on the front, protected by the clear window. Another useful feature is to indicate preferred settings Input channels 1 and 2 can take priority over all other on the front panel by inserting colored pins at the microphone and music inputs: preset levels of all knobs. You can then instruct a user • Input 1 can be activated by contact closure on the to set all the controls to the silver pins to configure PTT (push to talk). A 2-tone chime can be configured the system for their particular use. A second user can to precede an announcement. set all controls to the red pins for their configuration. • Input 2 can be switched automatically if a signal is fed to the input i.e. if someone speaks into the microphone (VOX activation).
2 | PLE‑1MAxx0‑EU Plena Mixer AmplifierIntegration Installation/Configuration NotesA telephone / 100 V emergency input with VOXactivation is provided for easy integration with anotherPA system or a telephone paging system. It has its ownpreset volume control and overrides all other inputs,including call station and inputs 1 and 2.The unit also has a line output to add amplifiers forlarger systems with more output power. This outputcan be switched to music only, for example, so thatmusic on hold can be provided for the telephonesystem.Power Rear viewThe mixer amplifiers come in 30, 60 and 120 Watt Parts Includedoutput power. This power is directly available on 100 Vconstant voltage connections and on a low impedance Quantity Componentsconnection for an 8 ohm load. Moreover, the amplifiershave a separate 100 V call-only output channel for 1 PLE-1MAxx0-EU Plena Mixer Amplifieraddressing areas where only priority announcements 1 Power cordare required. The call-only output can also be used for3-wire remote, volume control override. 1 ManualOutput status 1 Set of 19”mounting bracketsAn LED VU meter monitors the master output.
