Zapco ST-5X II
The square, low profile chassis also means it will be easy to trim out for a great looking installation so your system will look as awesome as it sounds. And speaking of sound...This is a Zapco amplifier and sound is what it’s all about. These are Class A/B Zapco amplifiers.
The Studio-X have the same high quality caps, op-amps, and bi-polar outputs that made the C2K and Reference series amps the industry standard for sound quality.
Product Details
There are six full range amplifiers in the Studio-X series and all are Class A/B and all use
bi-polar output devices for the smoothest possible sound. And, all are packed with all those features you want. Common features of the ST-X amplifiers include variable HP/LP/ Full Range electronic crossovers, variable bass boost, variable gain by channel pair, speaker level input, heavy duty positive lock terminal blocks and preamp outputs to daisy chain out to the next amp in your system without having to add more RCA cables. And the most important feature shared by all the ST-X amps is the legendary Zapco sound quality, developed with over 40 years of experience.
For 2015 we have done something truly unique with the ST-4X II, we have taken this top seller and tweaked it to create the ST-4X SQ for the customer who appreciates the finer points of the music and wants to invest a little extra for a more “live” sound. We did this by upgrading the caps and op-amps and making few other changes. The SQ version will have a more open sound and a more precise sound stage. We also used Tiffany style panel mount RCA connectors on the SQ for a solid signal transfer.
This year we bring you the Studio-SQ III series with a new high efficiency finned chassis and temperature controlled fans to assure that your amplifier plays all day long with no problems of overheating, even when you get that urge to really boogie. And with the new chassis, we even made a few tweaks to the internal components to take the sound quality up another notch.
With the new Studio-X SQ III you get the sound quality that other companies offer only in their big competition amps (and better than many of them) in a new fan cooled aluminum heat sink for improved efficiency and reliability, with 70W RMS/Channel @ 4Ω and 95W RMS/channel @ 2Ω (100W/Ch. @ 4Ω and 150W/Ch. @ 2Ω for the ST-6X SQ III). You also get plenty of features, like 12dB/octave multi-function crossovers, bass boost, variable gain and even pass-through RCA outputs so you can daisy chain amps.As for performance, the Studio-X SQ III gives you more than power. These amps have less then 0.1% THD+noise and over 95dB signal to noise for multi-ch. amps; less then 0.1% THD+noise and over 100dB signal to noise for mono amps.
