DATA SHEET
General Description
The 100 watt per channel, four-channel MA 4 amplifier achieves
unparalleled power density, reliability and features in a space
saving 1U, 19 inch rack mount chassis weighing only eight
pounds (3.6 kg). A universal-voltage switching power supply
provides near perfect Power-Factor, reducing peak currents to
⅓ compared to non power-factor-corrected supplies. A long list
of unique features ranging from constant load power to built in
automatic redundancy switching to advanced dynamics control,
qualify the MA 4 for the most demanding fixed installation
applications. The MA 4 excels in music & paging systems, small
conference rooms and speech reinforcement applications requir-
ing multiple amplifiers. Advanced dynamics control algorithms
adapt to changes in temperature, load impedance and sensitivity
setting.
The result is a truly plug-and-play amplifier that ensures
excellent signal integrity at all times.
