    Digital Designs S4 Staggered 4ch amplifier

    Item(s) for Sale:
    Digital Designs S4 Staggered 4ch amplifier



    Item(s) Description/Condition:
    Selling my Digital Designs S4 four channel amplifier to make room for more stuff. The amp is in good condition aside from the normal slight scratches on the mounting tabs and some on the body. Other than that the amplifier is in perfect working condition. One of the RCAs was not putting out so I sent the amp back to Digital Designs for the repair and they also performed a full check up prior to returning the amp back to me. The amp is in perfect working condition. Since the repair the amp had been used for three weeks. This amp is great with the staggered output. Perfect for running powering the front stage and bridging the rear for subs.


    The S-Class amps have more of everything, more power, higher slope xovers, high grade pots and components. This amp class is aimed at the more complex installations where higher channel power, finer control and more precision is needed. The S-Class amp circuit uses higher capacity power supplies, bigger transformers, higher damping factor and higher current flowing PC Board's than the C-Class circuits. This amp class is further divided into two different chassis types. The S Class are full sized chassis amplifiers for high wattage applications and the SS Class are small chassis amplifiers where space is in short supply but sound quality is still a priority. The S-Class brings higher end design into affordable price points.

    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.

    Re: Digital Designs S4 Staggered 4ch amplifier

    It would go well with my S2 and my Z-Se, but unfortunately I have no room/use for it....

    Bump for a great amp.
