The Studio-D SQ MINI Amplifiers
With the new Studio-D SQ MINI amps you get the sound quality that other companies
offer only in their big competition amps (and better than many of them) in a incredibly
compact chassis. But these little beasts aren’t just small, and they aren’t just powerful.
They had to earn the Zapco name before we put them into production.
They have all the advanced features you would expect... and more. Thanks to a brand
new technology, we are able use the NXP Class D solution to get amazing power and
performance in a incredibly compact chassis with over 90% efficiency.
The Mini-Amps Series includes two 4-channel amps with 50 Watts RMS/Ch @ 4Ω (ST-64D
SQ MINI), and 95 Watts RMS/Ch @ 4Ω (ST-104D SQ MINI) at less than 0.5% distortion, and
a 530 Watts Mono amp (ST-501D SQ MINI).
The ST-64D and ST-104D have also the HD Bluetooth Module port, so you can fire up the
music on your phone, tablet, or other Bluetooth smart device. Equipped with crossover
controls, high and low inputs, sub outputs, etc... they are the perfect choice for any
application where the minimum space is important. Efficiency is also very high, so they
are optimal for powerful system in electric cars.

A new level of Sound Quality
Zapco has a reputation for sound quality that is unsurpassed. It is our dedication to sonic
purity and our passion for performance that built that reputation. With all the new
amplifiers coming into the market, none has been any threat to Zapco's standing as the
premiere amp and processor company for pure sound quality.
Just check out the audio competition scene. The pros know what to use to win.
Competition amps however, do not come cheap, and not everyone wants to compete.
The challenge then, was to put Zapco's 40 plus years of experience to use in the
development of an amplifier that would bring Zapco sound a line of products for every-
day use and that everyone could afford. And the studio line is just that amplifier. In the
time it has been out it has built a reputation as the best sounding amp in the class.
Of course, not everyone buys strictly by sound (although they should). Maybe it's the
wrong color, maybe it's too big... or too small. But one thing is constant. Everyone who
hears the studio amps agrees; it sounds better than any other product in the class.
History of the Studio Series
Perfection cannot be achieved. But that does not make its pursuit less valuable. Zapco is
committed to making every product we make better than the last. We introduced the
ST-X amps in 2013. In 2015 we improved the PCB design and upgraded components to
make the sonically improved ST-X II.
Three years ago we introduced the Studio SQ amplifier to take affordable sound quality
to a new level. We added the proprietary RCA connectors from the Z-LX amplifiers,
changed the capacitors to a higher end audio cap, and made a few other small changes.
All this takes took the Studio sound to a new level of sonic performance for an affordable
amplifier.
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.

ST-64D MINI
What makes the MINI amps truly amazing are their extremely small sizes.
The ST-64D MINI measures only 15,1 cm (6”) x 8,6 cm (3,4”), and the ST-104D MINI is only 23,6 cm (9,3”) x 9,5 cm (3,7”).
