- 1. Communications Systems | PLE‑2MAxx0‑EU Plena Mixer Amplifier PLE‑2MAxx0‑EU Plena Mixer Amplifier ▶ 6 microphone/line inputs plus 3 music source inputs ▶ 100 V, telephone and a call station input with priority & VOX ▶ 2 zones and announcement only output ▶ Voice activated emergency override ▶ High output power 120 and 240 Watts ▶ 2-tone chime built in (7 more chimes optional with call station) ▶ Outputs for line out, music only out and insert point ▶ 24 V backup input with built in 24 V charger ▶ Separate tone controls for microphones and music sources These Plena mixer amplifiers are high performance, When one or both inputs are configured to have priority, professional public address units with modern state of the the amount of attenuation (reduction) of the cinch inputs, art features. They are easy to use, taking the complexity can be set between ‑2 dB (little attenuation) or -∞ dB away from the user and putting it where it belongs, inside (mute). This provides a talk-over or voice-over function. the equipment. Providing a crisp call or clear music is as Input channels 1 and 2 also feature selectable speech easy as turning on the radio. filters to enhance the clarity of announcements. The amplifier is also surprisingly affordable, without Music inputs sacrificing features such as ducking, priority and Separate music inputs are available with their own input flexibility. selector and volume control. The user can choose a music source like a CD player or radio (like the PLN-DVDT), and set the level of music. Functions You can set the desired sound for the music source Microphone and line inputs separate from the mic/line inputs. So if the music needs boosted low frequencies, this does not lead to muddy All Mic/line inputs can be switched between microphone sounding voices from the microphones. A truly unique level and line level sensitivity. The inputs are balanced but feature in its class. can be used unbalanced. Phantom power can be switched on to provide power to condenser microphones. Personalized settings More unique features are available such as detachable Input channels 1 and 2 can take priority over all other labels where the user can write the names for inputs, microphone and music inputs: music sources and zones. These labels can then be • Input 1 can be activated by contact closure on the PTT mounted on the front, protected by the clear window. (push to talk). A 2-tone chime can be configured to precede an announcement. Another useful feature is to indicate preferred settings on • Input 2 can be switched automatically if a signal is fed the front panel by inserting colored pins at the preset to the input i.e. if someone speaks into the levels of all knobs. You can then instruct a user to set all microphone (VOX activation). the controls to the silver pins to configure the system for their particular use. A second user can set all controls to the red pins for their configuration. www.boschsecurity.com

Certifications and Approvals Power These Plena mixer amplifiers come in 120 and 240 Watts Safety acc. to EN 60065 output power. This power is directly available on 100 V EMC emission acc. to EN 55103-1 constant voltage connections and on a low impedance EMC immunity acc. to EN 55103-2 connection for an 8 ohm load. Moreover, the amplifiers have a separate 100 V call-only output channel for addressing areas where only priority announcements are required. The call-only output can also be used for 3-wire remote, volume control override.
