QA SERIES More
Product overview:The QA series is a compact, lightweight amplifier designed for advanced touring and stationary installations. The QA series can also be configured to match a variety of load impedances, allowing customers the flexibility to customise different speaker models and scenarios. Power for QA series applications is a new solution for weight and size. The high efficiency of the heat dissipation system integrated with the patent heat dissipation technology makes the weight 40% lighter than the traditional power amplifier of similar power.

Detailed introduction

Protection function is available, short circuit, overheat, overload, overcurrent, output dc, soft start, current fuse protection, transformer overheating protection

Intelligent constant power technology

When the load connected to the amplifier is lower than the rated range, the output power will be controlled intelligently and will not be increased.

Resonance soft switching technology

It is specially designed for high quality and demanding professional power amplifier, also known as zero voltage on and zero voltage off technology, to eliminate the di/dt impact caused by conventional power supply switch.

Class D circuit with advanced technology

Class D circuit, the work effectiveness of 93%, can easily push 16 Ω ~ 2 Ω load, unique design protection to promote a great work in a safe operating area. HiFi fever circuit level.

The switching power supply is specially equipped with series parallel double loop power supply resonance technology

Effectively prevent the power source radiation to the tone interference, better than the power frequency transformer output wave type, more delicate and soft tone.

Humanistic aesthetic design

This is a completely refreshing unique appearance design, the entire front structure into a three-dimensional three-dimensional shape space, giving a strong visual sense of movement.

Wide operating power supply voltage

Wide working power supply voltage 160V~240AVC, all-weather protection to solve the equipment does not work and damage caused by voltage fluctuation.

1. It is specially selected to match the highest end push-to-tube with excellent performance in the United States, so as to make the dynamic response and timbre performance more outstanding and exquisite, and it is a rare hi-fi restore circuit.

2. The new high temperature automatic compensation constant temperature technology, when the working temperature rises to a certain level, the circuit automatically intelligent detection and adjustment, so that the machine work in the safe temperature range, to ensure the safety of the machine in any environment.

3. Special audio power supply for power amplifier, with double ring resonance and resonance soft switch technology, make the whole machine safe and stable, dynamic performance is better.

4. IC adopts pure imported components with low noise and extremely high sound reduction, high precision resistance, capacitance to ensure the delicate performance of the circuit and zero drift.

5. The high-density copper radiator used in aviation, together with the unique thermostatic intelligent temperature regulation circuit, can easily reduce the working temperature of the machine to the lowest level and ensure the high stability of the machine.

6. Passed the national compulsory safety 3C certification

7. The new high temperature automatic compensation constant temperature technology, when the working temperature rises to a certain level, the circuit automatically intelligent detection and adjustment, so that the machine works in the safe temperature range, to ensure the safety of the machine in any environment.
