Description
Specification

The RH-AUDIO 5 Zone USB/BT/FM/RDS/DAB/DAB+ Mixing Amplifier provides the solution of Digital audio broadcasting (DAB+), the signals of which are transmitted in-band, on-channel (IBOC). Several stations can be carried within the same frequency spectrum. And with outstanding features including improved sound quality, reduced fading and multipath effects, enhanced immunity to weather, noise, and other interference, and expansion of the listener base by increasing the number of stations that can broadcast within a given frequency band.

Designed with a 2U height housing including removable rack mounting brackets, and overall 70/100-volt and 4/8 ohms(Ω) loads and featured an industry leading 5 zoned 100-volt load solution.

A variety of audio source options have been engineered into these amplifiers including MP3 player of connecting an external USB drive, wireless Bluetooth receiver, five microphone interfaces, and two aux RCA ports.

120/240/350 watts of amplifier power is available, with provided an audio output to 5 different zones within the venue, each zone has its own separate switch on/off manually operated on the front panel, and each zone has its own LED indicator, shall light green for on.

Built-in CHIME and SIREN circuitry with push button and volume control on front panel. Microphone input (MIC1) fitted on front panel features muting function by overriding the other inputs of MIC2,MIC3 AUX1,AUX2 with 0~30dB attenuation.
