Why must use
Inter-M
digital amplifiers?
High Performance
DPA-SERIES amplifier shows up superior and uncomparable performance to any other digital
power amplifier in domestic and overseas market.
We offer S/N and THD which have more excellent performance compared to the same level of
other companies’ digital amplifier. Also, it is economically feasible because it consumes lower
power.
※ S/N : The value is Signal to Noise. The more the figure is high, the more clean sound can play
without noise.
※ THD : This is the abbreviation of Total Harmonics Distortion. The more the figure is low, the more
clean sound can play without distortion.

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. Also, there are many choices by offering diverse amplifier outputs such as
360W, 600W, 900W, 1200W with 1~4 channels amplifiers.
High Efficiency
All DPA-SERIES AMPLIFIER occupies a small space for installation
compared to the existing analog amplifier by designing as 2 unit size.
And it is able to design economical system which provides high
efficiency by minimizing spaces and power consumption with
low-power drawing and various channel setup.
It occupies rack spaces of 12 unit once 4 channel is composed
of the existing analog amplifier, but the space can be saved more
because only 2 unit rack spaces are needed once DPA-300Q
uses 4 channel amplifier. Also, it is very economical compared to
analog amplifier in the aspect of power consumption once only 1/7
level of power consumption is ready to be used.
