    Re: Xtant 403a amplifier pair (two)

    what these amps are capable of?

    Frequency Response 5 Hz to 50 kHz +/– 3 dB
    Number of Channels 3
    Watts per Channel @ 4Ω
    2 x 50 + 1 x 100
    Watts per Channel @ 2Ω
    2 x 100 + 1 x 200
    Stereo Ch. Bridged @ 4Ω
    1 x 200
    Distortion (THD) < .04%
    Signal to Noise Ratio > 100 dB
    Damping Factor > 200 @ 100 Hz with 4Ω Load
    Input Sensitivity 100 mV to 8.5 V RMS
    Unbalanced Source
    100 mV to 17 V RMS
    Balanced Source
    Input to Line Output Gain 0 dB +/–20 dB,
    Selectable in 10 dB Steps
    Line Outputs: Yes
    Crossover CM12HP & CM12LP Included
    Module Ports 4
    for Amplifier and 1 for Line Outputs
    Power Supply Fully Regulated, Pulse Width Modulated
    Operational Voltage 11 to 15 Volts
    Fusing No On-Board Fuse
    Fusing Requirement 60 Amp
    Size (L x W x H) 18.5 x 7.6 x 2.25

    the amps have four channel inputs and three channel outputs. i'm selling them as a pair because they are PERFECT for a 3-way active front stage. you have 50Wx2 for tweeters, 50Wx2 for mids, and 100Wx2 for midbass - and the power is very clean.

    you can assign any crossover or pair of crossovers to any channel pair. no limitation on what channels can do, and jumpers allow for easy bypass when used with an external processor.

    Buyer can ask me any questions anytime. I will continue to offer "tech support" on them and I ask for "first dibs" if the buyer sells them again.

    Re: Xtant 403a amplifier pair (two)

    i would much prefer these go to someone wanting to compete but having 100W for tweeters and 300W for mids will keep up with most SPL systems.

    they are still on ebay. i just got a message on eBay asking to sell just one. I revised the auction to be just one amplifier and will create another auction if someone wants. otherwise, i'll just sell one and keep the other for the wife's car.

    "more power" is relative. the THD is so low on these amps, it's plenty of power. and the power supply can actually keep up. keep in mind some amps can be rated such that only once channel is capable of providing rated output at a time due to the power supply losses - and also note these are fully regulated so you don't lose output just because supply voltage drops. it got louder than I ever needed and didn't get close to clipping. anything louder isn't SQ and is into hearing loss range anyway.
