Inter-M DPA-430H เครื่องขยายเสียง Digital PA Amplifier

DPA-430H is a quad channel 300W amplifier70/100v capable of delivering a total 1200 watts of Power respectively housed in 1 RU 

compact chassis. 

These Class D amplifiers offer High power in reduced size and weight. The combination Class D type amplification

circuitry combined with SMPS (Switch mode Power Supplies) creates a high efficiency amplifier offering reduced power consumption

and low heat dissipation. 

The DPA-430H offers 4 channels of High impedance Ideal for applications where high power and large quantity of long-line speaker

installation is required such as Airports Arena, shopping malls, transportation stadiums or any large scale facilities.

Feature

- 1U Rack Size

- Multi channel power amplifier, 300W x 4 channel (100V/33.3Ω  or 70V/16.3Ω )

- Independent SMPS power supply for each channel

- Low power consumption, low heat dissipation and light weight

- High pass filter switch (–3dB at 65Hz/400Hz)

- Protection circuitry (over heat, over current, speaker short, DC output)

- Balanced input
