The 100W per channel, four-channel Rane MA 4 amplifier achieves unparalleled power density, reliability and features in a space saving 1U, 19" rack mount chassis weighing only 8 lbs (3.6 kg).

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 1/3 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 requiring 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.

Features

  • Universal voltage, power-factor-corrected power supply
  • Very low inrush current
  • 100W x 4 channels in 1U chassis
    • If you don't need this much power, please see the MA3 Multichannel Amplifier
  • Built-in load monitoring
  • Remote fault reporting and redundancy switching
  • Optional 4-channel 70/100 volt transformers in 1U chassis
  • Adjustable high-pass filters and remote level controllable
  • Advanced dynamics control adjusts for sensitivity setting, load Z and temperature
