CLASS T DIGITAL
AUDIO AMPLIFIER

Introduction:
Thank you for your purchase of the Dayton Audio DTA-1 Class T Digital Audio
Amplifier.
Don’t let the compact size fool you; the DTA-1 amplifier has the heart of a serious
performer. Inside the DTA-1 is a proprietary Class T amplifier circuit, designed
to create more efficient and higher quality audio amplification using digital signal
processing, reducing power wasted as heat, meaning more music power to your
speakers. The resulting soundstage, tonal balance and sound quality—combined
with a modest price—makes this pint-sized T-Amp one of the “soundest” audio
amplifier investments you can make!
The DTA-1 is remarkably affordable, yet still delivers a crisp, vibrant signal that
compares to most high-quality linear amplifiers. Perfect for home or at play
applications as the unit operates on eight AA batteries for portable use or the
included AC adapter can be used to power the DTA-1 for indoor use.
