Digital Power Amplifier DPA Series DPA-300S / 300D / 300T / 300Q / 600S / 600D / 900S / 1200S 13_DPA-SERIES_BR_E.indd 3 13. 11. 8.
Inter-M, the History of Korea PA AMPLIFIER Inter-M has supplied commercial amplifier to domestic and overseas market for about 30 years starting from PA-2500 amplifier in the beginning of business. Inter-M has concentrated on developing/manufacturing commercial amplifier for a long time and our excellent ability to develop the world-class amplifier and produce the best are highly recognized. As a result, we supplied to JBL and YAMAHA which are the major pro-audio enterprises in overseas in the past.
Why Digital Amplifier? The main issue is ‘EFFICIENCY’! Efficiency in amplifier is watt’s ratio to be supplied to achieve the expected output from the amplifier. For example, a 92% efficient amplifier requires about 1300W to be supplied to achieve 1200W output. On the other hand, 50% efficient analog amplifier requires 2400W power. Thus, the existing analog amplifier requires more power to achieve the same amount of outputs.
High Power Inter-M is proud to present high power digital amplifier with rated output 1200W based on amplifier drawing technology accumulated in Inter-M. DPA-SERIES Amplifier has the know-how of Inter-M synthesizing high-efficient and high power SMPS power operation technology which is core technology of digital amplifier and Class-D amplifier technology, so we could overcome the output limitations of high impedance amplifier.
Diverse Line up DPA-SERIES amplifier is ready to display the total 8 kinds of diverse line up from 300W to 1200W, from single channel(1Ch) to quad channel(4Ch) and select amps to suit the use. ·1CH : 300W / 600W / 900W / 1200W (4 Type) ·2CH : 300W + 300W / 600W + 600W (2 Type) ·3CH : 300W + 300W + 300W (1 Type) ·4CH : 300W + 300W + 300W + 300W (1 Type) Thorough Quality Control System The driving force to play a Korean leading sound industry for 30 years is thorough quality control system.
PA (Public Adress) PA DPA SR SR (Sound Reinforcement)) Specialized SMPS Operation Small, Light and High Efficient SMPS Operation DPA-SERIES is greater than 94% high efficient SMPS and greater than 92% high efficient amplifier and has achieved high efficient SMPS and amplifier beyond the limitations of world top-class amplifiers. High Power SMPS Operation beyond PA / SR Ranges A distance between amplifiers and speakers can be long in PA system, so impedance is supposed to be bigger by line.
The relationship between the output of amplifiers and the impedance of speakers Speaker combined impedance value of maximum output in amplifiers or the value of output voltage can be achieved via the following numerical formula. Combined impedance value can be achieved because maximum output voltage is fixed in PA amplifier.
DPA Series DIGITAL POWER AMPLIFIER AC&DC Dual Power Operation AC & DC dual Power operation. Normal power operation via AC 220~240V electrical power input. Amplifier will switch automatically to DC 24V battery backup supply input when AC power is interrupted. Power On/Off Control with Dry Contact The user can control the Power On/Off at a long distance by using a control input. Quad DPA-300Q Priority Program Override Each amplifier module has 2 audio inputs.
