[QUOTE="ricebowl, post: 8517687, member: 609456"] Digital Designs S4 specs: The S4a is a non-symmetrical output, 4 channel power amplifier. It features two channels with 2 x 100 Watts of power, plus two channels with 2 x 200 watts of power. This allows the amp to make more power where it is needed most. The S4 can be configured to run a variety of systems. The 100 x 2 channels have 24dB/oct high pass, variable from 20Hz - 500Hz. The crossover also uses a 10x frequency switch, this moves the crossover range to 200Hz to 5kHz. There are 4 calibrated dial markings to help frequency settings. The 200 x 2 channel has the same 20-5kHz high pass and 50 - 5kHz low pass, 24dB/oct, with 10x frequency multiplier switch. Each filter has individual on/off switches for ultimate flexibility. A clipping indicator circuit is included to monitor real power conditions. The amp uses separate power supplies for each set of channels. Configurations: * 200 x 2 to power midrange door speakers with variable band pass, 2 x 100 to tweeters with variable high pass. * 200 x 2 to power front component set or coax speakers, 2 x 100 to power rear fill. * 100 x 2 to power front speakers, up to 700 mono to drive rear sub(s). * 3 channel amp, 200 x 3 for surround sound use. * 2 x 150 + 2 x 300 in 2 Ohm stereo use, to power double sets of coax/components. * 2 x 175 + 2 x 350 in 1 ohm stereo use, to power more sets of coax/components. With 3-way variable crossovers and two sets of bridgeable, staggered output channels, you can do anything a system design needs.
