AESPCM series parameters

PCM series

PCM series amplifiers are AES’ flagship series of two-channel SMPS amplifiers. The R&D department, which has been developed for more than 15 years, has the most advanced technology in the application of audio power amplifiers, so that the PCM power amplifier can transmit huge power density and present perfect sound in a lightweight 2U rack (the highest power PCM20, per channel 4600W @ 20) . This ultra-high performance and ultimate efficiency, through SMPS regulated power supply and AES patented Class™ power amplifier module, makes the PCM amplifier series a world-class touring sound reinforcement application.

feature

  • SMPS powered.
  • High performance Class I™ amplifier module.
  • High CMRR balanced input for enhanced signal-to-noise rejection.
  • Top electronic accessories.
  • Maximum stability is maintained under continuous full power operation under 2Ω load.
  • Separate channels on the front panel have temperature, protection and peak clipping warning lights.
  • Independent channel power indicator and -5dB / -10dB / -20dB signal indicator on the front panel.
  • The rear panel has a power circuit breaker.
  • Rear panel sensitivity switch selection (32dB / 1V / 0.775V).
  • Three modes on the rear panel (Stereo/Bridge/Parallel)
  • Rear panel XLR input sockets and link sockets.
  • SPEAKON NL4 output socket on the rear panel.
