You don’t have to settle for wimpy, muddy sound just because
you’re on the go. The AT-PHA100 Portable Headphone Amplifier is small (width
and length comparable to a smartphone) but packs a powerful punch. Engineered
using select audio components, and enclosed in all-aluminum casing to protect
the circuitry, the AT-PHA100 gives headphones a rich, detailed boost throughout
the sonic range with ultra-low distortion.
The AT-PHA100 is equipped with both analog and digital inputs (3.5 mm jack and
USB micro-B, respectively) and 3.5 mm headphone jack. It also features a
high/low gain switch, machined aluminum volume knob, and five-stage sampling
indicator for digital input. The internal lithium polymer rechargeable battery
lasts up to 14 hours when amplifying an analog signal, and up to 6 hours when
amplifying a digital signal.
The amplifier comes with two rubber bands and a rubber mat for strapping the
unit to a smartphone or other portable device, a 1.0 m USB cable (USB 2.0 to
USB micro-B) and a 10 cm audio cable terminating in a 3.5 mm gold-plated stereo
mini plug at each end.
