    Dayton Audio’s Small but Mighty DTA-PRO Amp Officially Launches

    [​IMG] (February 27, 2019) Another week, another Dayton Audio product launch. Yesterday, the budget friendly company announced the official release of its DTA-PRO 2.1-channel portable amplifier. This feature rich amp is super compact in size (1.2" H x 5.2" W x 5" D), allowing owners to introduce power and convenience without needing a large amount space.

    At its core, the DTA-PRO is 100 watt Class D amplifier capable of delivering 50 watts per channel (2 channels, 4 ohms, 20Hz – 20kHz). That allows the amp to cleanly drive fairly demanding speakers. But its connectivity options, which include wireless Bluetooth 4.2 with aptX along with PC USB, 3.5mm stereo, coaxial, and digital optical, give the amp the ability to deliver varied playback convenience.

    The DTA-PRO carries an onboard DAC that features a 192kHz/24-bit sampling rate usable with sources connected via coaxial and optical inputs (USB delivers 96kHz/24-bit performance). It also offers a single sub output (2.7 VRMS) for line level connection with a powered subwoofer.

    The included wireless remote gives users access to EQ presets, both bass and treble output adjustments, and track control when sourcing media from digital sources.

    Much like other Dayton products, the DTA-PRO is priced to save you cash. It carries an $196.10 MSRP, but can currently be purchased on parts-express.com for $142.45.

      That's an interesting little amp! The great unknown is the quality of the DAC. I can see that it is a TI DAC on the PE website but a quick search turned up little detail or reviews. I know it is all about the implementation in some respects :-) but more info would be nice.

      The other question is who makes the Class D amp modules? There are a glut of Class D amp modules out there now... some really good... some so so.... A quick glance at the specs didn't yield any clues (unless I just missed it).

      Maybe I shouldn't quibble about something at this price point because on the surface it has incredible specs, functions, and utility!

      Thanks for passing this along! It looks like a good option for a desktop system with passive speakers!

      A quick look around informs me (guesses) that the Dayton Audio DTA-PRO 100W Class D Bluetooth Amplifier with USB Chipset is comprised of SA9023 + CS8416 + TAS5342A + TAS5508C + DAC PCM1808 + NE5532

      SA9023 - USB to Coaxial I2s Processor Chip Support 24 Bit 96k Sampling.
      CS8416 - Cirrus Logic Digital audio receiver that supports sample rates up to 192 kHz
      TAS5342A - Texas Instruments Series Audio Amplifier...
      TAS5508C - Texas Instruments 8-channel digital pulse-width modulator (PWM) that provides both advanced performance and a high level of system integration.
      DAC PCM1808 - Texas Instruments (Burr-Brown?) high-performance, low-cost, single-chip, stereo analog-to-digital converter with single-ended analog voltage input. A 24-Bit Delta-Sigma Stereo A/D Converter
      NE5532 - Texas Instruments Dual Low-Noise High-Speed Audio Operational Amplifier

      Remember TI acquired Burr-Brown in 2000...

      I saw most of that in my quick look as well. I did not know that TI had acquired Burr-Brown however. It's neat to think that Burr-Brown tech is driving the TI DAC side of things... It can't hurt!

      Thanks!!
