The KLR Series
KLR-Series amplifiers are high-efficiency, lightweight high power amplifiers incorporating
the latest amplifier technologies.
The series provides a power range of 1000 to 2500 watts per channel at 2 ohms (20Hz-
20kHz, 1% THD). The KLR series is available in 2 channel versions at four power points.
All models will drive 2, 4, or 8 ohm loads.
*The KLR 3200 can also be used as a two channel 70V distributed output amplifier
providing up to 800W per channel. For 70V applications, Ashly recommends setting the
amplifier’s HiPass filter switch to 50Hz (see page 5).
