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.
