It is a power amplifier with four independent output channels, each directly connected to a speaker, without any front-end signal processing function. This design allows the amplifier to focus on amplifying the signal without any signal processing or adjustment, ensuring the purity of the signal and high fidelity sound quality.
Characteristics of Four Channel Pure Rear Stage Amplifier
Pure signal: Due to the lack of pre-processing function, the four channel pure post amplifier can provide the purest signal amplification, avoiding distortion and noise that may be introduced during signal processing.
Independent adjustment: Each channel can be adjusted independently, suitable for multi-channel systems such as home theaters or professional audio systems, ensuring consistent and interference free sound performance for each channel.
High power output: Usually used in situations that require high-power driving, such as professional stage performances, large audio systems, etc., it can provide stable high-power output.
