NANOBASS X4
COMBO AMPLIFIER
(Keyboards-Guitar-Bass)
Thank you for purchasing the NANOBASS X4. A great deal of dedication and
passion went into designing and building this no-compromise, high performance
combo amplifier.
It was conceived to be a dedicated amplifier for the “connoisseur” bassist.
Reading and following this manual will enable you to get the best performance
from the amp and ensure its longevity.

OVERVIEW OF THE (X4)
The NANOBASS is a single channel combo amplifier for multiple instruments such
as Bass, Guitar, ukulele, violin, E-drum .that has an 6.35 Jack input socket
for instrument, an 3.5 stereo jack auxiliary input for iPad/iPod, or drum
machine, and a 3.5 stereo jack for your headphone. It features 3 band EQ that
is perfectly tailored for your instruments, it also can play music with the
Blue Tooth(5.0 with aptX HD) function.
Using our extensive R&D facility which includes the largest anechoic chamber
in the bass guitar amplifier industry and the KLIPPEL transducer measurement
system (it uses lasers!), we were able to develop the perfect 4 inch
loudspeaker. We analyzed the neodymium magnetic system, the cone behavior at
all frequencies in 3D representation, cone suspension and frame, etc., until
we had achieved a transducer beyond what anyone would have ever thought
possible. Then we looked at the acoustic loading using the acoustic simulation
software and calculated exactly the full power cone displacement at every
frequency.
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 PIB 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
acoustic damping materials to prevent cabinet coloration 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.
Audio front end on the Amp system of NANOBASS is one ADC chip PCM1861 from
Texas Instrument. With special configuration, 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 TASS805 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 resolution sound. With low-ripple
switch-mode power supply and integrated DSP-based active 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 distortion and higher resolution Bluetooth audio
playback than what traditional SBC can provide.
NANOBASS may be built for practice 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 tiny cube.
AMPLIFIER FEATURES

FUNCTIONS OVERVIEW
-
Input Jack
This is a high impedance input and is designed for all passive and active -
Input Level Control
Different instruments and also different playing styles and even players will affect the signal level so adjust this control so that the signal overload Clip light does not light up. This optimizes the best signal to noise ratio between amp and instrument and will give you the full extent of the amplifiers tone and power. -
Clip Light
when the power amplifier is overloaded and causes distortion, the CLIP light will light up in red. -
Auxiliary Input(3.5mm stereo)
This is a stereo mini jack and can accept any signal from iPod, iPad, smartphone or drum machine. -
Auxiliary / Bluetooth level control & Mode select
Rotate: Increase or reduce the input level for AUX and Bluetooth;
Press: switch AUX/BT input mode, keep press will disconnect the Bluetooth. -
Aux/BT mode Indicator
Blue light steady lit: Bluetooth;
Green light steady lit: Aux input.
Note: For initial pairing, the blue light will Rash when Bluetooth input is selected, after pairing is successful, the blue light will be steady lit. -
Headphone lack
You can use any kind of stereo headphones on this jack but remember you will only sound good in your headphones if they are high quality. -
Bass Control
Boosting or cutting this will have significant effect on the weight of the -
Mid Range Control
Boosting or cutting Mid-range. -
Treble Control
Boosting or cutting treble. -
Master Volume
This controls the volume of instrument input. -
Power Switch
This switches off the amplifier from the DC supply but AC signal will still be in the external supply. We advise that you disconnect the power supply from AC source if you do not intend to use the NANOBASS for long periods of time. -
Power Indicator
Will light up when you have power cable connected and amp switched on.
NOTE: When power is on, the indicator will light up, if no signal come in the standby mode will activate after 30 minutes, the power indicator LED will light up with red. When a signal
come in from INPUT or AUX socket, the amplifier will restart in about 2 seconds. -
AC INPUT SOCKET
Connects the amplifier to the AC power supply.
NOTE: TURN THE VOLUME DOWN on the NANOBASS before plugging in your instrument.
TRANSPORTING AND STORING THENANOBASS
When transporting in a vehicle, it is recommended that you use an external
case or heavy-duty cover to prevent it being damaged by falling over or other
objects falling on it.
When Storing:
- Keep in a dry location preferably at room temperature.
- Do not store in temperatures below -20 Degrees C or above 40 Degrees C.
- Do not allow it to get wet. If this occurs, never turn it on in this condition.
