Input Filter
Boosts your system’s response by matching the amplifier’s range to your speakers. Prevents speaker
bottoming and low-frequency muddiness. Each channel is separately adjustable: 50 Hz for most compact
full-range speakers; 30 Hz for subwoofers and large full-range systems; and OFF for studio monitoring.

Clip Limiter
When the RMX is pushed to extremes,the clip
limiter automatically finds the exact point of
overload and keeps the amplifier in its “Peak
Zone,” preventing severe distortion without
reducing performance.
The low-frequency filter and clip limiter are
independently adjustable for each channel.
Thermal Management System
Provides continuous variable speed fan for quiet
operation. Rear-to-front air flow keeps amps
and racks cool.
