The versatile HA-2 is the second model in the Bighead series and is a step up model of the popular HA-1 Bighead with added technology and features. The HA-2 is a high resolution USB audio interface that supports PCM playback with up to 384 KHz sample rate/24 bit resolution. On DSD playback, sample rates of 2.822MHz and 5.644 MHz are supported, making it the ideal choice for musicians and engineers that desire high performance and the purest sound quality.

This audio juggernaut is a rechargeable lithium ion dynamo that is ideal for use in practice or recording situations. It also functions as a headphone booster amp as well as a preamp to drive powered amplifiers. The HA-2 has both passive and active instrument inputs with a 2 band EQ that is ideal for guitar and bass, yet versatile enough for use with other instruments. On top of this, it has an internal lithium-ion rechargeable battery that is fed by its USB jack, so any computer or appropriate cell phone charger can charge it in less than 3 hours, but it can play for up to 8 hours.
