Specification

AP series of power amplifier by the unremitting efforts of R & D engineers, the depth of raw materials carefully screened, carefully compared, and then after rigorous testing of aging, to achieve high damping coefficient, ultra-low distortion, high signal to noise ratio, with sensitive overheating management System and safety Perfect protection circuit to ensure that the equipment can work in harsh environments, longer life, work more stable and reliable, you use more peace of mind. In ensuring sound quality but also playing to improve the efficiency of the machinery, making the product to become the first of many engineering products.

A series of five power models to choose from, with a professional input and output interfaces, make more convenient, a variety of operating modes (stereo, mono, bridge) can be used according to the actual situation free to choose.

1. Equipment more secure Excellent convection cooling system.

2. The new line design, greatly improving the efficiency of machinery.

3. Perfect phase response and ultra-wide frequency response.

4. LED indicator clarity, work status at a glance.

5. Professional HI - FI (high fidelity) design, the sound performance of natural.

6. Very high industrial design requirements, reasonable layout, safe and reliable, the whole body simple.

AB main channel operating mode (stereo, mono), with low cut, input level selection. Bass channel has a high cut, phase, ultra-low frequency adjustment and other functions. When used according to the actual situation free to choose. Multi-function, multi-channel machine design, suitable for a variety of different occasions, voice transmission and PA requirements.
