4CH Professional Power Amplifier

The DSA-500Q is a high-power 4-channel professional amplifier that can deliver high performance in environments such as school auditoriums, music rooms, government offices, cultural centres, and religious facilities that require high-quality sound.

You can input 4 analogue audio channels and Dante™ digital audio, and you can use the built-in DSP to tune the system to suit your environment for better sound quality.

In addition, high efficiency digital amplifier technology and various protection circuits enable stable operation.

Features

• High quality CLASS-D 4CH Professional Amplifier
  DSA-500Q is a High Performance Class-D Power Amplifier using SMPS power and can reproduce high-quality audio in various environments such as auditorium and performance hall.
• 4CH Dante™ Digital Audio Input
  You can input 4CH Dante™ digital audio through the network port and 4CH analog audio inputs.
• Built-in DSP
  Parametric 8 band EQ, crossover filter 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
  You can use the Butterworth / Bassel / Linkwithz-Riley filter to adjust the frequency band required for your speakers.
• Unlimited preset creation for environment-optimisation
  Up to 10 presets can be saved to the internal memory of the device. In addition, environment parameters can be saved to a PC as a file via the PC GUI and can be easily managed without restriction on the number of files.
