All the ARX SX series of amplifiers are designed around
'over-specified' Toroidal power transformers and Heavy
duty diode bridges.
To retain dynamic range under even the heaviest load
conditions, the SX series all utilise large multi capacitor
arrays for high peak current outputs.
All models can be switched to run in bridged mono mode.

How Much Power?
Choose the amplifier power output that’s just
right for your application from our Power Chart.
Please Note:
When comparing amplifier power
ratings, remember that these are true RMS pow-
er ratings and should not be confused with the
unsustainable peak ratings often claimed by
other amplifier manufacturers.
