AE-2 PORTABLE HEADPHONE AMP
| The HeadAmp AE-2 is our
new portable headphone amp. The AE-2 has the ability
to drive just about any headphone in the world, from 16 to
600 ohm impedance.
The AE-2 looks and feels like a solid brick. The front
panel consists of a pair of 3.5mm audio jacks (a headphone
output and an audio input) located on opposite sides of the
panel for convenient placement of cables. In the
center is the volume knob and a pair of mini red LEDs
indicating power and charge status. Everything is
labeled with precise laser engraving and won't ever fade or fall off. |

The amp's power switch - a slide-type designed
to be difficult to accidentally flip while located in a bag or
pocket - along with the DC adapter jack and a pair of RCA inputs are
located on the back panel. While the amp does have two inputs
(the RCA and the 3.5mm inputs), only one should be used at a time.
The other jack can then be used as a loop/tape output.
| A gain switch
is recessed underneath the amp and allows the AE-2 to be set
for up to 3 different gain levels. At any gain level
and with any headphone, you'll find the AE-2 to have a
completely silent background. A Lithium-Ion battery pack powers the AE-2. Lithium-Ion
batteries have a greater power density than NiMH or NiCad
rechargeable batteries resulting in a 30 hour battery life -- about
3 times longer than a 9V NiMH battery. Lithium-Ion batteries
are also excellent for audio, their low impedance able to supply
large amounts of current quickly. |

An included DC adapter charges the
internal batteries - it takes about 3 hours for a full charge from
empty, and the amp can be used while charging. The use of the
DC adapter while charging does not induce any hum or hiss into the
audio as the amp remains on clean regulated power. The AE-2 has
a safer, smarter and more sophisticated charging system than most
amplifiers.
