The PLENA all-in-one mixer amplifier is a versatile solution for public address, emergency announcements and back-ground-music (BGM) requirements. This high-performance device is easy to install and operate.

Typical applications of PLENA all-in-one 180W mixer amplifier include use in supermarkets, restaurants, schools, retail chains, canteens, places of worship, gymnasiums etc where BGM provides the right atmosphere, at the same time announcements can be made clearly and with ease.

System overview :
The All-in-one amplifier is mixer amplifier with inbuilt music source.The All in one unit can provide hours of uninterrupted music from USB or SD flash memory.The unit also has a built in FM tuner with presets. To ensure for optimum performance, the All in one unit has no moving parts, such as hard drives that can fail or wear out. The unit is supplied with an IR remote control for controlling the music source.The unit can be rack mounted by using the brackets that can be procured seperately.

Functions :
Microphone and line inputs :
The mixer amplifier has four microphone inputs. Separate level controls are available for all the inputs. For all the inputs (except Aux input), phantom power can be switched on to provide power to condenser microphones. Inputs 1 and 2 can be configured between line and mic level sensitivity. Inputs 3 and 4 are for connecting microphone only. Microphone inputs 1 and 2 have a combo connector so that both XLR and 6.3mm TRS connectors can be used for connecting microphones.Other microphone inputs are standard XLR connector.

Music source and music input :
The unit has one music input and an internal music source. There is a source select button on the front panel to select between auxiliary input and internal music source.The internal music source plays MP3 files from an SD/MMC card or USB device with a capacity of up to 32 GB. The player will automatically search and play all playable MP3,WMA files and has repeat and random play modes. The following formats are supported: MP3,WMA files with bit-rates from 32 kbit/s.

FM Tuner :
The digitally controlled FM tuner uses a frequency synthesizer for accurate capture of radio stations and has five presets to store favorite radio stations.

Integration :
A 100V emergency/telephone input 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 music input and mic/line inputs. The unit also has a line output to add booster amplifiers for larger systems with more output power.The unit has a 24VDC input for backup power supply.The unit has a RJ45 connector for integrating with the PLE-2CS Call station.

Outputs :
An LED VU meter monitors the master output. A headphone socket, below the VU meter, provides the mixer output. The power is directly available on 100V constant voltage connections and on a low impedance connection for a 4 ohm load.The line out provides the line level mixer output through the XLR connector.

Zones :
The mixer amplifier has two zone outputs. The music can be switched on and off in the zones via the front panel. Announcements from the PLE-2CS two-zone call station can be routed to zone 1 or zone 2, or both. Announcements from the Telephone/100 V input is routed to both zones and can override the microphone and PLE-2CS signals.
