AESAK series Datasheet

AK Series

AK series power amplifier provides the best choice for those who have the limit in space and long time in full power amplification application, for the high quality Class D technology power module in AES, also with 2U rack. At the same time, the efficient Class D power amplifier module provides unprecedented sound quality.

Features

  • Class D power modules.
  • Highly sensitive CMRR balanced inputs for improved noise rejection.
  • Maximum stability even at continuous full-power operation on 2Ω loads.
  • XLR input and signal link connectors.
  • SpeakON NL4 and binding post output connectors.
  • Input sensitivity selector on the back panel (32dB / 1v / 0.775v).
  • Routing mode selector on the back panel (stereo / bridge-parallel).
  • Channel independent temperature, protection and clip warning indicators on the front panel.
  • Channel independent power and -5dB / -10dB / -20dB / signal presence indicators on the front panel.
  • Parallel and bridge indicator on the back panel.
