OVERVIEW OF THE BP-200 AMPLIFIER
The BP-200 is a D-Class power amplifier and a pure class A single channel pre-amplifier
housed in a machined aluminum/steel enclosure. D-Class amplifiers are highly efficient
and therefore produce far less heat than the conventional class AB amplifiers. The
compactness and light weight allows this amplifier to be carried in the musician’s
instrument gig-bag.

FEATURES
• A switchable input, for active (high-output) and passive (high pickup impedance)
basses.
• Single switch ACTIVE/PASSIVE/MUTE.
• Variable input sensitivity control to match instrument output with amplifier.
• Input overload indicator.
• Sub sonic filter to reduce excessive loudspeaker cone motion.
• Dedicated 3-Band EQ for total tonal control of instrument.
• Headphone out jack.
• Balanced line out with pre/post EQ and ground lift switches.
• Pre amp output (Line Out jack).
• Neutrik high-current socket can accommodate ¼ jack or a Speakon plug.
• Main Power on/off switch.
• IEC AC input 100-240 volts AC. (Operates on all world voltages).

FRONT PANEL AND BACK PANEL OVERVIEW
1.INPUT /MUTE SWICTH
Top Position: Mute On
Middle Position: Low sensitivity for mainly active basses. For basses with onboard
electronics. Input matched for low signal to noise ratio and optimum transfer of
electrical signal from modern high-end active basses.
Bottom position: High sensitivity for passive basses that do not have active
electronics, suited for older ‘vintage’ basses. This setting is precisely matched to high
impedance pickups enabling them to faithfully reproduce the true frequency and
dynamic range of the instrument.

2.INSTRUMENT INPUT JACK
This is a standard ¼ inch mono jack socket.
For the best possible sound, we recommend you use the PJB BI-12 instrument
cable as it has very low self-capacitance and absolute shielding resulting in
greater transparency of sound and less noise than other instrument cables.

3. LED CLIP/MUTE INDICATOR
Green is Mute, Red is overloaded input.
4. INPUT LEVEL ADJUSTMENT
This is a fine-tuning adjustment (+/- 10dB) to get the precise match from your
bass to the amp. When the RED LED is continuously lighting up, reduce the level
on the input level control.
5. BASS EQ CONTROL
6. MID RANGE EQ CONTROL
7. TREBLE EQ CONTROL
8. MASTER VOLUME CONTROL
This is the master volume control and it controls how much power you send to
your speakers as well as the line out socket on the back of the amp. When setting
up your tone or plugging in your instrument, you should keep this control at a low
level. All instruments are different when it comes to how much output is from the
pickups. Likewise for players, depending on how hard or soft you play. Note this
control is a true “Audio Taper” control so that the level position may be set higher
compared to other amps that use a “Linear Taper” control. The “Audio Taper
control has far more precision in controlling your output and uses the full rotation
to control level, unlike Linear controls that just use the first few degrees of turn
and give the impression the amplifier has more volume than what it actually has.
9. AUXILLARY INPUT SOCKET
10. HEADPHONE OUT SOCKET
We recommend the PJB H850 headphones as they were designed for bass and
high-fidelity music reproduction. They are a perfect match to the BP-200.
When a headphone is connected to the jack, the speaker output will be
disconnected and the sound from you speakers will be muted.

11. LED POWER ON INDICATOR
12. BALANCED LINE OUT
This is an ultra-low impedance (200Ω) balanced line out for use with recording or PA
mixing consoles. This output is not controlled by the volume control. Changing the
level on your instrument, or input level will however, vary the DI output.
13. BALANCED LINE OUT GROUND LIFT SWITCH
Sometimes AC Hum is induced into a sound system due to that both PA and bass amp
are connected to different ground potential (known as ground loop). This switch
disconnects the amps grounding to PA or recording system to eliminate this hum.

14. BALANCED LINE PRE/POST EQ
This switches the EQ in or out on balanced line. You may choose the tone you have
on your amp to go into the PA or for recording or you can use external EQ on
mixing console the signal is sent to.
15. LOUDSPEAKER OUTPUT
The BP-200 amplifier will work on any load from 16Ω down to 4Ω, which is the safe
maximum load for this amplifier. This socket accepts both Speakon and ¼ inch jack
plugs. Do not use a standard instrument cable as these are not designed to work
as speaker cables. If you use this type of cable the sound quality will be severely
degraded. Use a proper speaker cable with 12-to-16-gauge wire. The shorter the
speaker cable is, the better the sound quality will be as shorter cables have less
resistance For Speakon type cables, we recommend that you use PJB SS-3 or the
Higher Performance SS-4 high current speaker cables. These dedicated high-
current, low-resistance cables. Using inferior, higher resistance cables will greatly
impair the performance of your system.
16. AC INPUT SOCKET
This accepts grounder IEC cables. This amp can work on any AC voltage from 100-
250volts.
17. POWER ON/OFF SWITCH
This switches the main power on and off in the amplifier.
OPERATION & POSITIONING
TURN THE VOLUME DOWN on the BP-200 before plugging in your instrument.
Connect the speaker or speakers to the BP-200. For best results with this amplifier
you should use PJB loudspeaker cabinets and PJB cables. We highly recommend
the PJB SS-4 speaker cables for amplifier to cabinets. As they have virtually no loss
so there is maximum transfer of power from amplifier to speaker.
Try not to excessively boost the EQ on bass frequencies as this may hurt your
speakers.
If you hear that your speakers are distorting and the overload indicator is on,
TURN DOWN THE VOLUME CONTROL!
The BP-200 amplifier is rated as 210 watts into 4 ohms but that does not mean it is
the maximum output power. This is the output power without audible distortion.
Hard driving the BP-200 can cause it to over power beyond 300 WATTS with
distortion. It is always a good idea to have speaker power handling to be double the
amplifier power rating. If the amp is subjected to some kind of overload signal, then
the speakers won’t blow.
For the best possible sound, we recommend you use the PJB BI-12 instrument cable
as it has very low self-capacitance and absolute shielding resulting in greater
transparency of sound and less noise. Using this cable will give a richer tone to your
instrument.
