1 Digital Power Amplifier DPA-O SERIES

2 SUMMARY The DPA- O Series offers both low impedance and High impedance outputs in one package Ideal for applications where high power and large quantity of long-line speaker installation is required. The superior efficiency of a Class-D amplifier means higher power output and greater compactness than an analog amplifier offers. OVERVIEW The DPA-O Series is a amplifier operate in 4 8 ohm/ 70v/ 00v modes and are capable of delivering a total 00 watts of Power. Respectively housed in RU compact chassis, these Class D amplifiers offer High power in reduced size and weight. The combination Class D topology amplification circuitry combined with SMPS (Switch mode Power Supplies) creates a high efficiency amplifier offering reduced power consumption and low heat dissipation. The DPA-O Series offers both low impedance and High impedance outputs in one package 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. Inter-M, PA AMPLIFIER CLASS D Class D audio amplifier offer greater power efficiency over traditional amplifiers. Among their advantages is their reduced physical size and lower heat dissipation. They offer less than 0.% THD, total harmonic distortion with an increased signal to noise ratio to 0dB and a widened frequency response from 50Hz ~ 0kHz Class D audio amplifier offers greater than 90% power efficiency over traditional amplifiers. SMPS - Switch mode power supply provides high efficiency and low weigh. Among their advantages is their reduced physical size and lower heat dissipation. The DPA-O series is fully equipped with a protection circuit against short circuit, overload, power and DC output. Same Powerful Output from a More Compact Amp The superior efficiency of a Class-D amplifier means higher power output and greater compactness than an analog amplifier offers. Only rack units in size, the DPA-O Class D audio amplifier with ECO Digital design offers greater than 90% power efficiency and lower heat dissipation over traditional low efficiency and noise from analog amplifier.

3 Efficiently Compact and Lots of Power Class-D amplifiers overcome the inefficiencies of traditional Class-A or AB amplifiers. The Inter- M DPA-O Class-D amplifiers transform very little power into heat so a higher percentage of the power supply is transformed into the load. This results in a very compact amplifier which needs less input power to produce very high output power. Why Use Class D-Amplifiers Class-D amplifiers deliver more output watts ratio to input AC power than conventional analogue amplifiers. How? The Class-D amplifier s PWM (Pulse Width Modulator) modulates the original audio input signal with a triangulated signal wave which has a much higher fixed frequency. The result is a digital signal which contains both the input signal and a band of frequency components around the modulation frequency. A LPF (Low Pass Filter) then filters out the high frequency pulses and the resulting amplified output signal is then sent to the speakers. Analog Amplifier Digital Amplifier 00% Power Trans. Amp.

4 THD : Total harmonic distortion THD: Total harmonic distortion stands. The lower THD means that the equipment produces a more accurate reproduction by reducing harmonics added by electronics and audio media. S/N : Signal to Noise Ratio S / N Ratio: stands for Signal to Noise Ratio expressed in db. It is a measurement that compares the level of a desired signal to the level of background noise. It is defined as the ratio of signal power to the noise power. The higher the ratio indicates more signal than noise.

This is possible because the amplifier operates in a constant voltage output hence delivering maximum power. The following mathematical formula based on Ohms Law demonstrates the relationship between speaker impedance, power and voltage.
