This RH-AUDIO high-power audio amplifier is a device that amplifies electrical signals that have been adjusted to an appropriate volume and tone sent from the mixer or pre-amplifier, give high power outputs 1000/1500/2000 watts optional, specially designed for big installations where large number of speakers are required in a variety of commercial and industrial installations.

When they run power through miles of cable, they minimize resistive power loss by running the power as high voltage and low current. To do this, this amplifier uses a step-up audio transformer at the power station and a step-down transformer at each speaker's location. This reduces power loss due to the heating of the power cables.

The same solution can be applied to audio communications in the form of a constant-voltage system of typically 100 volts and 70V. Such a system is often used when a single power amplifier drives many loudspeakers through long cable runs (over 60 feet) for P.A., paging, or low-SPL background music.

With universal balanced XLR and 1/4" plug jack for picking up the signal from audio mixer and preamp, while a group of outputs for extra power amplifiers. And features many of the same comprehensive protection circuits typical, complete protection is provided for output short circuit, overload, high temperature, peak current limiters with individual level led indicators on the front panel.

Its rack ears allowing the unit to be mounted into a 3U rack space. All the sophisticated features make these amplifiers fairly ideal for PA systems with applications such as paging the announcement, background music and audio broadcasting in convention-halls, shopping centers, dining rooms, and recreation areas etc.
