  • Description
  • Specification
In the pa system the Preamp RH2011P takes whatever source it gets from microphone,CD/USB player or FM/AM tuner, and prepares that signal with a medium to high output impedance and current for the power amplifier to drive loudspeakers.

The rear panel is designed with three auxiliary inputs of RCA stereo connections,which are converted to mono internally.

And four mono auxiliary outputs are ready to connect four power amplifiers.

Its five 6.35mm jack ports allow for more options on the usage of microphones,one input "MIC1" is fitted on front with precedence over other inputs.

2-band equalizer (bass and treble) allows you to adjust the lower or higher frequency sounds to achieve the ideal performance.

Each auxiliary or mic. input enjoys its individual level control with adjustment knob on front panel,moreover a master level knob controls all inputs.

This preamp has highlighted tone generators of CHIME and SIREN,with pushbuttons on front panel to ensure easy and fast operation.

Fire Alarm Connection:On the rear of the amplifier,there is a 'Priority' input for the direct connection of a fire alarm system.

This will mean when the fire alarm sounds,the amplifier and speakers will mute,ensuring an emergency evacuation can take place.
