Class D amplifier circuit, the efficiency of the whole machine is equal to the digital amplifier, and the sound quality and timbre are not achieved in general.

PHD9600 amplifier has A, B, C, D four channels (4 x 600W / 8 Ω), each channel individually work mode.The PHD9600 amplifier USES the high fidelity acoustic Wima capacitance, the Rubycon power supply capacitor, the German wiring port output, the whole machine has no connecting line to make the process beautiful, the performance is more stable;In order to obtain the higher product performance, the system high voltage and low pressure signal separate layout;The circuit board adopts the multi-laminar process, and the switching power supply adopts PCM87 series magnetic core.Super power output.The excellent quality of the material and process to ensure the PHD9600 high-fidelity, high damping coefficient of the power amplifier, speaker can apply to all kinds of high power and high part there is a requirement for selective listening to the speaker, is widely used in concert, stadium, concert hall, performing arts center, theater, opera, etc.

A-Guard Protection System

1. Class A protection system is A comprehensive protection system of PHIVID fit-rhyme products, with the best limited circuit;Instead of relying on one-to-one circuits to solve different problems, a-level protection systems focus on and coordinate all protection functions.Therefore, A class A protection system can only be implemented when necessary, which is why the PHD is capable of continuous full power in complex capacitive loads.

2. Intelligent pressure limiting technology, in the case of input 0 to 8V signal, the amplifier can be kept in a linear working condition. 

3. The whole machine adopts SMD element with SMD, and the circuit transmission distance is shorter, eliminating interference and improving audio performance.At the same time greatly reduce the manual operation, product reliability and long-term stability are guaranteed. 

4. The machine power supply section, we set up excellent at almost any cost of active power factor correction PFC, greatly reduce the total power supply current power supply circuitry, eliminate harmful harmonic current, meet with Europe and the United States electric industry electrical demand for power factor, this is a rare in the field of high power amplifier. 

5. Use the company independent research and development of terminal feedback technology and multi-point network absorbing circuit, the damping coefficient of the power amplifier to a staggering 1800 above, which promote the corresponding power amp is easy, natural, a very good sense and control.
