AJ7003 is a three-channel power amplifier with a class AB circuit design.
It's elaborately designed for the commercial market, such as multi-function
halls, conference rooms, restaurants, shopping malls, and so on.
AJ7003 has 3 individual channels, one for bass, and two for satellites.
It's easy to make a 2.1 sound system with AJ7003.
Outstanding Sound System
The bass channel of AJ7003 can work stably at 2Ω load with the power up to 1600W.
It means AJ7003 can drive two subs.
Adjustable Crossover Point
Both the left and right channels of the AJ7003 have rotary crossover. The user can
adjust the frequency between 70Hz - 120Hz according to the characteristics of the
audio system to create an ideal audio system.
Configurable Sound Effects
Users can connect more audio devices through the RCA connector on the back
a panel of the Aj7003 and configure different sounds according to their own taste.
