A source switch selects between Bluetooth and the audio input, which is nice because it prevents someone else’s phone or tablet from overriding the analog input unintentionally. I focused on two measurements. The first was frequency response, which measures how evenly an amplifier reproduces sound throughout the audio spectrum. In car audio, many mid- and upper-range speakers operate at a nominal 4 to 8 ohms, while subwoofers generally run between 1 and 4 ohms. Peak capacities are only relevant at a certain point, and even the advertised RMS doesn't necessarily reflect the exact performance of a given model.

The Tone’s chassis is extremely compact at just 3 7/16 inches wide, so it takes up very little space on a desktop or shelf. Frequency response (how evenly an amplifier reproduces sound throughout the audio spectrum) wasn’t as good (or flat) as we’d like, but because the error occurs at the lowest and highest parts of the audio spectrum, it’s only marginally audible. The main circuit then takes the regulated and readable source and adds volume, equalization, and effects, preparing the new and improved signal for its eventual path to a large cone. I asked the following questions: I concluded by running lab measurements of the amplifiers to confirm (or, as it turned out, deny) their power ratings and other specifications according to Texas Instruments guidelines (PDF). Couple this with its 100 watts RMS per channel output and five input options, including Bluetooth 5.0, and it lives up to its appearance.
