Want to bring your music listening experience to a new level? Simply put a Micro Amp between your music source and favorite headphones and let the beautiful music come flooding in. Designed to bring fine audio electronics into in an affordable & space-saving amp, the Micro is ready to inhabit any tiny nook on your desktop, nightstand, or any other listening place where you have access to AC-power. (For battery-powered, mobile listening please check out our HeadRoom Portable Micro Amp.)
Sure it sounds great, but the HeadRoom Micro Amp is also an all-singing, all-dancing, fully-featured headphone amp & pre-amp. The Micro Amp uses top-shelf true 'Class A'-biased electronics and the discrete-component Walt Jung Diamond buffer-based output amplifier electronics of our pricier Desktop Amp, but employs smaller 1/8" (3.5mm) connectors and smaller controls to fit it all into this tiny package. The Micro Amp is a Class-A, DC-coupled amp (no capacitors in the signal path) so you know the sound will drive even the most power-hungry headphones effortlessly. The HeadRoom Micro Amp has a headphone jack on the front, but it also has a pre-amp jack on the rear panel that you can use as a volume-controlled audio source for a power amp or your powered speakers. It also has two line inputs that are switch selectable from the front panel for easy switching between sources (an iPod and a computer, for example). A front panel gain control switch allows you to adjust the volume ranges to easily control headphones of a variety of impedances and efficiencies; and, of course, our famous HeadRoom Crossfeed circuit that improves the audio image on headphones very subtly and carefully.
The Micro is enclosed in an amazingly sturdy and lustrous black anodized aluminum enclosure with urethane bezels (the rubber piece around the front and back panel). The bezels handily act as bumpers protecting the amp, and they allow you to securely stack the Micro Amp and the Micro DAC units together. All HeadRoom Micro Amps are hand-built in Montana, USA.
An external AC power-supply 'brick' comes included with the HeadRoom Micro Amp. An upgraded international-use Astrodyne Power Supply is optionally available for audiophiles wanting to fully maximize the audio performance of the Micro Amp. The Astrodyne works anywhere on the planet you can find an outlet [from 100V ~ 240V] so it makes a great accessory for frequent travelers. Plus, the Astrodyne also improves upon the sound quality when compared to the 'stock' power supply.
*The Micro Amp does NOT include any interconnect cabling. To hook up your Micro Amp to a portable audio player, you will need a mini 1/8"-to-1/8" (3.5mm) interconenct cable. We recommend the Cardas 6 inch or 12 inch mini to mini cables. For longer runs, we suggest the Cardas 1 meter or 2 meter versions. If you are using an audio source with RCA outputs, the Straightwire 0.5 meter MusiCable cable will work great, or simply browse all of our cables.
The Micro Amp is 1.5" (3.8cm) high, 3.5" (9 cm) wide, and 4.5"(11.5cm)long. It weighs only 8.8oz (250 grams). The HeadRoom Micro Amp is hand-built in Bozeman Montana USA.
