Owner's Manual
We designed a custom Rectangular Auxiliary Low Frequency Radiator (RALFR®). It also
reduces the cone excursion of the speakers, allowing greater power handling.
The proprietary PJB NeoPower 4-inch speakers have full frequency range to the highest
audio frequencies. Not only does this give greater clarity and transparency to your
instrument, but also a high-fidelity sound to any backing track fed into the auxiliary
input.
The cabinet may be as small as a shoe box, but it is built to the same standards of all
PJB cabinets, heavily braced internally and damped with acousc damping materials
to prevent cabinet coloraon that can kill the true sound of your instrument. What you
hear from the NANOBASS is the closest you can get to how your instrument actually
sounds.
TAudio front end on the Amp system of NANOBASS is one ADC chip PCM1861 from
Texas Instrument. With special configuraon, the ADC is running at 96KHz sampling
rate to get wider frequency range and higher precision from the two analog inputs.
Amplifier system of NANOBASS is built with one piece high-efficient Class-D power
amplifier TAS5805 also from Texas Instrument. The chip is wired in Parallel BTL mode
to drive the woofer, and its 768KHz output PWM carrier frequency is ideal for rendering
high resoluon sound. With low-ripple switch-mode power supply and integrated
DSP-based acve crossover and dynamic range control, the amplifiers provide sufficient
horse power for the speaker driver.
NANOBASS also features an integrated Bluetooth audio receiver, which is built with
Qualcomm's latest V5.0 chipset QCC3031. The chipset can support aptX HD codec,
offering lower distoron and higher resoluon Bluetooth audio playback than what
tradional SBC can provide.
NANOBASS may be built for pracce use, while it sounds a lot more than that. The
sound image it renders exceeds its figure, and you may find it hard to believe the
overwhelming sound wave are coming from such a ny cube.
