PLENA all-in-one 180W Two Zone Mixer Amplifier

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.
