Dayton Audio DTA-1 Class D AC/DC Battery Powered Mini Amplifier 15 WPC
Don’t let the compact size fool you—Dayton Audio’s DTA-1 mini amplifier is a serious piece of audio gear. A proprietary Class D amplifier chip enables the DTA-1 to be 88% efficient while still producing pristine, high-resolution output. This makes the DTA-1 amp an obvious choice for powering high efficiency single driver speakers. Up to 15 watts of power per channel is on tap to drive desktop and bookshelf speakers, for the ultimate portable hi-fi setup at home or in your office.
The Dayton Audio DTA-1 can run off of 8 AA batteries for total portability, or the included switching power supply (with quick-release US and European style plugs) for stationary use. A rear mounted 3.5 mm stereo (1/8″) audio input is provided. The amplifier also includes a 6″ long, coiled male-to-male 3.5 mm cable for making connections to iPods, MP3 players, PCs, and portable CD or DVD players. Spring-loaded push terminals are incorporated for quick speaker wire termination. Intelligent short-circuit and over-temperature protection ensure amplifier longevity. The Dayton Audio DTA-1 is the perfect replacement for the now unavailable Sonic Impact 5066 NIB Class D amplifier. Dayton Audio has taken the technology developed for the Sonic Impact 5066 and perfected it in this hand-held digital amplifier. Includes 12 VDC, 2A power supply.
