The portable mixer amplifier is a professional public address unit with state-of-the-art features,which is built on class-D platform
The amplifier is easy to use,taking the complexity away from the user and putting it where it belongs,inside the equipment
Providing a crisp call or clear music is as easy as turning on a radio
Offering the essentials of public address in an affordable package
The portable mixer amplifier is designed to meet the requirements of the people who are on the go
It has an inbuilt music player which can support audio streaming through Bluetooth or USB/TF card and also supports FM
An IR remote control is supplied with the unit to control the music source
The amplifier can be powered either with a 12/24V battery source or via a power adapter,which is supplied with the unit
It is equipped with two microphone inputs,microphone input-2 comes with a phantom power supply option
It also has an AUX input option for connecting external audio sources
It also supports ducking,by which the background music automatically fades away when there is a live announcement from any of the microphone inputs and is automatically restored after the announcement,avoiding the manual intervention of the operator
The ducking option is variable and it can be switched off based on the user requirements
The processor in the amplifier monitors the speaker output line
In case there is a short circuit or overload in the speaker output line,the amplifier isolates the amplification circuit and enters into self-protection mode and the user is informed with a fault indication
The amplifier also monitors the battery status
If the connected battery output goes low,the amplifier will detect this and the user will be informed with a battery low indication:If the battery output goes below the threshold value,the amplifier will isolate the output and protect the battery from draining any further
The rear of the amplifier is equipped with a replaceable DC fuse for further protection
Features
Bluetooth,USB,FM and TF card slot for audio streaming
Variable ducking option
Supports 12/24V battery power supply
Low battery indication
Phantom power supply support
Functions
Power
The mixer amplifier comes with 30 watt output power
This power is directly available on a low impedance connection for a 4 ohm speaker load
The amplifier has a ducking feature,which will suppress the background music whenever there is a live announcement from any of the microphone inputs and the ducking levels can be varied based on the requirements from 0 dB,-6 dB to -24 dB,and MUTE(off)
The mixer amplifier can be connected to a higher capacity of power amplifiers with the help of line output
The amplifier is designed to suit application areas like retail outlets,small cafes/restaurants,election rallies,promotion campaigns,yoga centers and gyms,hence being the right choice for small and medium installations
Inputs
The amplifier is equipped with two balanced microphone inputs
The microphone input-2 is supported with phantom power supply with ON/OFF selection switch
Microphone input-1 is supported with 6.3mm TRS connector and microphone input-2 is supported with a combo connector
Music Source And AUX Input
The unit has an inbuilt music source module and AUX input option
The module streams audio from USB pen drive or from a TF card (supported capacity up to 32GB) or FM,the user can also stream the audio through Bluetooth
Amplifier Status
When the amplifier is powered on,the power LED ring lights up in green and this indicates that the amplifier is in normal operating condition
If the LED ring changes to red,it indicates that the speaker output line is in short state or overloaded condition
Once the speaker output line is rectified,the amplifier resumes and the LED ring status will change to green
The amplifier also monitors the battery status
If the amplifier is powered with a battery source,the battery ON indication LED will turn on
If the battery voltage level goes low,a battery low indication LED will blink and the outputs will be reduced by 3 dB
If the battery voltage levels goes further low - below the threshold values, the amplifier shall mute the outputs to prevent the battery from draining further
