The Phil Jones Bass Bighead Pro (HA-2) is a premium, multi-functional device engineered for musicians and audio engineers who demand tonal purity.
Studio Grade Audio Interface & Preamp
A significant step up from its predecessor, the HA-1, the Bighead Pro functions as a high-resolution headphone amplifier, an instrument preamplifier, and a sophisticated digital-to-analog converter (DAC).
It provides a high-performance audio solution for silent practice, studio tracking, and mobile recording, making it an indispensable tool for serious bassists and multi-instrumentalists.
At the heart of the HA-2 is a high-resolution USB audio interface capable of handling pristine PCM playback at sample rates up to 384 kHz with 24-bit resolution.
It also supports DSD playback at 2.822 MHz and 5.644 MHz, ensuring the ultra-low distortion and maximum transparency required for critical listening.
For analog performance, the unit features selectable passive and active instrument inputs paired with a dedicated 2-band EQ.
This allows users to shape the tone of their bass or guitar before the signal reaches their headphones, a recording desk, or an external powered amplifier.
Rechargeable Dynamo, Built for Travel
Designed for maximum portability, the Bighead Pro is housed in a compact chassis that weighs just 290 grams.
It runs on an internal lithium-ion rechargeable battery that offers up to 8 hours of continuous playtime.
The battery conveniently charges via standard USB power in under 3 hours, meaning it can be powered up using a laptop or a mobile phone charger.
With a powerful 300mW per channel output, it easily drives high-fidelity headphones ranging from 16 to 64 Ohms, ensuring a full and dynamic soundstage wherever you choose to play.
