Expand your headphone monitoring capabilities with the addition of this 4-channel Headphone Amplifier from Monoprice! This amplifier features four 1/4" (6.35mm) amplified headphone outputs, each with its own independent volume control. It features an extremely clean amplifier circuit, which produces a signal-to-noise ratio greater than 98dB. It accepts line-level audio input over the stereo RCA jacks on the back or headphone level through the optional 1/4" TRS jack. A switch on the back allows you to choose a mono or stereo output. The amplifier is powered by the included 12 VDC/500mA AC adapter.
