InterM DSA-300E amplifier

DSA-300E is a multi-channel amplifier for pro audio that is made based on technology from the Best Patent awarded DPA digital amplifier technology. It provides an optimum solution for dispersion in a multi-broadcast system as it can output a maximum of 300 W×8CH(4 Ω) or 600 W×4CH(8 Ω) by connecting the output in Bridge mode.
SKU: DSA-300E Category: Tag:
  • HIGH PERFORMANCE 8 CHANNEL CLASS-D POWER AMPLIFIER – High performance Class-D Professional Amplifier has up to 2400W (300W×8ch) power output.
  • SMPS (SWITCHING MODE POWER SUPPLY) POWER SCHEME – High efficient, light weight SMPS power system is utilized.
  • POWERFUL AND DETAILED SOUND QUALITY – High S/N ratio and Low THD reproduces powerful and detailed sound.
  • COMPLETE PROTECTION CIRCUITS – Complete circuit protection is activated in case of amplifier overheating, output shorting, overload, over power and DC output.
  • OPERATION INDICATOR LED – LED display to check the operating status (ACT, STBY, POWER, SIG, CLIP, PROT, BRIDGED)
  • BALANCED INPUT – This connection is used to ensure the lowest noise operation which eliminates the common noisefrom the cable.
  • STEREO / BRIDGED MODE SELECT – There is STEREO MODE that outputs input signals of each channel independently. The BRIDGED MODE binds CH1 and CH2 as one which enables bigger output than done in STEREO MODE.
