The PJB BigHead is not big at all. In fact, it is barely larger than an iPhone. The “Big” is about the sound. It functions rst as an awesome bass headphone ampli er with 2 band EQ ( +/- 18db @ 60 Hz and +/- 18dB @ 5KHz) set for optimization of all kinds of bass instruments.
Unlike consumer electronic MP3 players and smart phones that have very small power output of around 20 milli-watt to drive headphones, the BigHead has more than 10 times the power. This contributes to a far more exhilarating listening experience with increased resolution and dynamics. Even if you are just listen- ing to music, the BigHead will be a great improvement to your regular headphones, adding more listening pleasure.
A more important function of the BigHead is being a digital and analog recording tool, boasting the nest BURR BROWN digital components. The USB out is 48KHz 16Bit digital conversion. In other words, recording your bass onto Pro Tools will give you exactly what you wish for and absolutely nothing else.
Maybe you need an analog pre amp. The Big Head can do that too. It will provide up to 12dB of gain and bet- ter than 96dB signal to noise ratio. Just use the headphone out jack to feed an amp or mixer. It also has an internal lithium-ion rechargeable battery that is fed by its USB jack and can be charged with any computer or appropriate cell phone charger. Each charge provides up to 8 hours of play.
