Description
Besides integrated amplifiers RH-AUDIO also manufacture power amplifiers,which boost current gain by receiving
the lower-power audio signals from preamplifier or mixer to drive the connected loudspeakers.
The rack mount power amplifieris assembled with all the elements in a 2U chassis offering 350/450/650 watts,
available with either 70/100-volt or 4 to 16 ohms(Ω) loads.
The power amplifiers features XLR and 6.35mm input sockets also a group of link output to supply audio signal to additional 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.

Note:
Select only one output terminal of 70V,100V or 4-16 Ohms to be with COM.
Never use two "hot ends" to join together.
If other outputs are needed,please use the LINK output to connect another power amplifier.
Installation of Rack Mount Power Amplifier
Front amplifier is generally connected to the pure post stage amplifier, the front amplifier is used to amplify the voltage, the pure post amplifier is used to the amplify the current, the front amplifier is the link equipment between the various sound source devices and the power amplifier, as the output signal electrical level of the sound source equipment is low, the power amplifier can not work properly. The function of the front amplifier is exactly to amplify the signals.
The front stage is the voltage amplifier, which is also the part that influences the timbre the most in the whole equipment. The post stage is the current amplifier which is the real power amplifier part and has great influence on the dynamic and low frequency control power. The general power amplifier should be called the front and the post stage combined mixer amplifier. If we just talk about the technology, the front stage is more demanding than the post stage, which is more difficult to be done well. If you want to add special power lines, we shall not add good power lines in the post stage because the current of the post stage is large, we should add these good lines in the front stage.
The front stage includes the matching of input impedance, the amplification of the input signal voltage, the sound enhancement circuit of some amplifiers, the tuning circuit of the tone, etc. The post stage is mainly responsible for the amplification of the frequency, which is mainly the amplification of the current. Therefore, the quality of the front stage of the power amplifier is directly related to the quality of the power amplifier.
The front stage is mainly used to provide appropriate audio electrical level signals for the post stage and adjust the sound quality such as the high and low bass effect, the left and right channel volume and so on. The post stage, commonly known as pure post stage, it simply amplifies the audio signals provided by the front stage to provide enough power to drive the commercial pa speakers.
