PDS series

Rack-mount subwoofer-amplifier

models in the series
- PDS-500S / 250S switching power
- PDS-500T / 250T transformer

The AIM™ PDS series, in options of 500w or 250w, is low-profile, powerful mono-channel amplifier created for mounting onto 19-inch cabinet to produce strong power of low frequency sound with high dynamic range
All the power amplifiers in the PDS series are class-D and driven by high efficient switching power supply (SMSP) for low weight and less heating, or toroidal (core) type of transformer for long persistence of power delivering.
The PDS amps are featured with modern DSP function for presetting, storing and quick retrieving of the amplifiers’ main parameters such as crossover frequency and slope, EQ, phase, volume, for the optimum acoustic refinement.
The PDS models are crafted to be slim of 1U, which saves great amount of the valuable space available in the 19-inch cabinet.
Being ECO friendly all the PDS amplifiers are with power saving function, which turns the amplifiers into standby automatically when audio signal is off.
The overload / shortage protection circuitry protects the amplifier from being destroyed if it’s
mis-connected or misused.
