Built-in DSP

Parametric 8 band EQ, crossover filtear using HPF and LPF,delay, attack / release adjustable limiter.

Easy control of equipment through front panel with OLED and PC GUI

Using OLED and operation switches installed on the front, and DSA-500Q dedicated software, various parameters can be adjusted.

Easy one-touch front dust filter cleaning

It is possible to remove the front dust filter easily by separating the ventilator on the front of the equipment by one-touch method.

Simultaneous control of multiple amplifiers via PC GUI

The PC GUI allows intuitive manipulation of various functions of the DSP, and simultaneous control of multiple amplifiers through IP registration of the equipments.

Up to 340 ms delay time adjustable

When configuring a system with multiple speakers, you can adjust the Delay function to control the audio transmission time up to 340 msec for clear sound.

Frequency band adjustment using HPF and LPF
