The Bosch PLE-10M2-US 2 Charcoal Channel Plena Mixer is a high performance, professional public address mixer with modern state-of-the-art features. Combined with the PLE-1P120-US or PLE-1P240-USamplifiers, you can build an easy-to-operate yet powerful and flexible public address system. All this without sacrificing features such as ducking, priority and flexibility. The mixer fills a wide variety of public address requirements yet is surprisingly affordable.
All mic/line inputs can be switched between microphone level and line level sensitivity. The inputs are balanced and can also be used unbalanced. Phantom power can bewitch on 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 the PTT (push to talk) input or the input can be switched automatically if a signal is fed to the input, i.e., if someone speaks into the microphone (VOX activation).A 2-tone chime can be configured to precede an announcement. Input 2 also has a VOX possibility. When one or both inputs are configured for priority, the attenuation of theRCA input signal can be set between -2 dB (little attenuation) and -infinity dB (mute). This provides a talk-over or voice-over function. Input channels 1 and 2 also feature selectable speech filters to enhance the clarity of announcements.
Labels and colored pins
More unique features are available such as detachable labels where the user can write the names for inputs, music sources and zones. These labels can then be mounted on the front, protected by the clear window. Another useful feature is to indicate preferred settings on the front panel by inserting colored pins at the preset levels of all knobs. You can then instruct a user to set all the controls to the green pins to configure the system for their particular use. A second user can set all controls to the red pins for their configuration.
A telephone / 70 V emergency inputs with VOX activation is provided for easy integration with another PA system or a telephone paging system. It has its own preset volume control and overrides all other inputs, including call station and inputs 1 and 2.
The mixer has two zone outputs. The music can be switched-on and off in the zones via the front panel and optional wall panel. Announcements from the PLE-2CS two-zone call station can be routed to zone 1 or zone 2, or both. Announcements from the tel/70 V input or inputs 1 & 2 are routed to both zones. Input 1 can be used for a PLE-1CS allcall call station or any other microphone or call station with a PTT contact. The unit also has a line output to connect the preamplifier output before zone selection, making it possible to create a third zone. This output can be switched to music only, for example, so that music on hold can be provided for the telephone system. Loop-through input and output connections enable external sound processing equipment (e.g., an equalizer or Plena feedback suppressor) while maintaining a balanced connection to the amplifiers.
