DPA-300D/DPA-600D: Power Amplifier

-Various line-up by output 

DPA series is a product maximizing the efficiency of PA digital amplifier and its stable operation is possible. Various lineups by channel & output demanded from the market are configured and you can install the product by considering the size and installing environment. 

-Efficient and rational digital amplifier 

Inter-M’s digital amplifiers can output higher power even with remarkably lower power consumption than conventional analog amplifiers, has less heat, and is light in weight. Therefore, you can establish economic and environment-friendly system as effective saving in installing space and costs comparing to analogue amplifier.

-Perfect support for DC 24V power supply for emergency broadcasting 

The DPA series is designed with an AC / DC dual power supply that allows DC 24V supply through the battery even if AC power fails due to power outage. Since the DC power supply is an emergency power supply, it operates regardless of whether the power switch is ON or OFF. Also, when AC power is restored normally during DC power operation, it is automatically switched to AC power and driven. 

-Emergency broadcast can be played through priority input 

With the Priority function of the DPA series, alarm broadcasts can be configured to be output automatically in an emergency. When a contact is input to the PRIORITY terminal on the rear, the signal input to the PRIORITY terminal is output prior to the PGM input.

-High S/N, low THD for fine, clear sound reproduction 

The DPA series is a high quality commercial amplifier that can reproduce crisp, detailed sound without noise with high S/N of over 100dB and low THD of less than 0.1%. Therefore, it is very suitable for BGM playback, which is considered to be important in PA system recently, and is useful in large-scale franchise stores such as shopping malls, department stores, banks, and the like. 

※ S/N : This is a value that indicates Signal to Noise. The higher the value, the less noise can be reproduced. 

※ THD : Abbreviation for Total Harmonics Distortion. The higher the value, the more distortion can be reproduced. 

-Operation indicator LED to check status at a glance

SIG, -10dB output level, Clip, Protect, etc., can be intuitively monitored through LED lighting status and color by AC / DC power supply, STBY status, and each channel. In addition, through the volume of each channel on the front of the product, independent volume can be adjusted for each channel. 

-AC REMOTE that can turn on / off the power remotely 

Using the AC REMOTE terminal on the back of the instrument, you can turn the power of the DPA series ON / OFF at a long distance. When the DPA series is OFF, the power is turned on when the contact is input to the AC REMOTE terminal, and when the contact is turned on, the device is turned off. 

-Excellent protection with protection circuit 

The DPA series is equipped with various protection circuits such as OVP(Over -Voltage Protection), UVP (Under-Voltage Protection), Limiter* and OCP(Over-Current Protection) to detect and block I/O voltage higher or lower than the specified voltage range. This allows you to safeguard your equipment in extreme situations to prevent failures. 

* Limiter : DPA-900S/1200S Only 

※ Caution: Please check the impedance of the speaker line prior to use.
