Functions

Power

Bosch Ple-1me120-3in-Mixer Amplifier 120w Usb/Bluetooth come in 240 W output power. This power is directly available on 100 V constant voltage connections and on a low impedance connection for a 4-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.

Inputs

All mic/line inputs can be switched between microphone level and line level sensitivity.
The inputs are balanced, but can be used as unbalanced inputs.
Phantom power can be switched-on to provide power to condenser microphones.

Input channel 1 can take priority over all other

microphone, AUX & music inputs:
• Input 1 can be activated by contact closure on the PTT (push to talk). A 2-tone chime can be configured to precede an announcement.

Music source and AUX input

The unit has an internal music source and AUX input option. The internal music source plays audio files from an USB pen drive (with a capacity of up to 32GB) or streamed through Bluetooth.
The player will automatically search and play all playable audio tracks from the USB pen drive and has repeat/random/all modes.
The following formats are supported: MP3 and WAV files with bit rates from 32 kbit/s.

Personalized settings

Another useful feature is to indicate preferred settings on the front panel by inserting colored pins at the preset levels of all knobs. One user can make use of silver pins to set the controls as per his convenience.
A second user can make use of red pins to set the controls for his particular use.

Output status

An LED VU meter provides output indication. A headphone socket (6.3 mm), below the VU meter, provides the mixer output. For total reliability and ease of use, a limiter is integrated into the output stage to restrict output if the user applies excess signal
