Our product range contains a wide range of Headphone Amplifier and Plate Amplifier
Headphone amplifiers as referred to here are commercially available separate devices, sold to a niche audiophile market. These devices allow for higher possible volumes and superior current capacity compared to smaller, cheaper amplifiers that are used in most audio players. In the case of the extremely high-end electrostatic headphones, such as the Stax SR-007, a specialized electrostatic headphone amplifier or transformer step-up box and power amplifier is required to use the headphones, as only a dedicated electrostatic headphone amplifier or transformer can provide the voltage levels necessary to drive the headphones.
Most headphone amplifiers provide power between 10 mW and 2 W depending on the specific headphone being used and the design of the amplifier. Certain high power designs can provide up to 6W of power into low impedance loads, although the benefit of such power output with headphones is unclear, as the few orthodynamic headphones that have sufficiently low sensitivities to function with such power levels will reach dangerously high volume levels with such amplifiers.
A plate amplifier is a power amplifier that is built on a flat board for installation inside of a speaker. Like any power amplifier, a plate amplifier takes line-level signals and increases their power level to be able to drive a speaker. Unlike a standard musical amplifier, many plate amps have limited frequency response, befitting their typical use as a subwoofer amplifier. Plate amplifiers typically have a face plate with inputs, outputs, controls, and a power connection, along with exposed components on their other side. They are usually designed to be mounted inside the enclosure of a subwoofer, which is a specialized speaker designed to reproduce bass and subsonic frequencies. While store-bought subwoofers include their own amplifiers, hobbyists who build their own subwoofers cut a hole in the back panel of their unit and screw the plate amplifier into it. This hides the plate's exposed components while leaving its controls and inputs available. Typically the only connections on the interior side of the plate amplifier is a pair of speaker terminals which are used to connect the amplifier's main output to the subwoofer driver.
