OVERVIEW OF THE BP-800 AMPLIFIER
The BP-800 is a high power 800 wa D-Class power amplifier and a pure class A single
channel pre-amplifier housed in a machined aluminum enclosure.
D Class amplifiers are highly efficient and therefore produce far less heat than the
convenonal class AB amplifiers. Therefore no cooling fan is required in this design
which makes the amplifier an ideal unit for low volume operaon and studio work.
The physical shape and light weight allows this amplifier to be carried in the musician’s
instrument gig-bag

FRONT AND BACK PANEL DESCRIPTION
1. POWER ON INDICATOR
2. MUTE/ACTIVE/PASSIVE SELECTOR SWITCH
3. OVERLOAD INDICATOR
4. INSTRUMENT INPUT JACK
Bass instrument in here.
5. LOW BASS EQ CONTROL
This will adjust the fundamental tones of E and A strings on 4 string basses and B,
E & A on 5 string basses.
6. HIGH BASS EQ CONTROL
This will adjust the fundamental tones of D and G-strings on 4 & 5 string basses.
7. MID RANGE EQ CONTROL
8. LOW TEBLE EQ CONTROL
9. HIGH TREBLE (PRESCENCE) EQ CONTROL
10. AUXILLARY STEREO INPUT JACK
11. HEADPHONE OUT SOCKET
This jack accepts 3.5mm stereo headphone jacks. When a headphone is connected
to the jack, the speakers will be muted.
12. INSTRUMENT INPUT LEVEL
13. AUXILLARY INPUT LEVEL
14. MASTER VOLUME CONTROL
15. BALANCED LINE OUT XLR SOCKET
This is a 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 will however, vary the DI output.
16. PRE/POST EQ BALANCED LINE OUT
17. GROUND LIFT BALANCED LINE OUT
This allows the grounding of balanced out socket to be disconnected. This is useful
if you are experiencing hum caused by grounding loops/problems.

18. LINE IN: TO POWER AMP BYPASSING THE PRE-AMP
19. LINE OUT
FROM PRE-AMP, can be used for driving a second amplifier
20. FX SEND
Line out to FX pedals or FX rack unit.
21 FX RETURN
Line in from output of FX pedals or FX rack unit.
22. SPEAKER OUTPUT:
The BP-800 amplifier will work on any load from 16Ω down to 4Ω, which is the safe
maximum load for this amplifier. The jack sockets are in parallel so connecng two
8Ω speakers will result in a 4Ω total load. We recommend that you use PJB high
current speaker cables; which are dedicated high-current, low-resistance cables.
Using inferior cables will greatly impair the performance of your system, even more
so if you are running a 4 ohm speaker load.
Just to avoid any confusion, a speaker that has low impedance has a greater load
on the amplifier. So a maximum load refers to minimum speaker impedance as more
current is flowing through the amplifier’s output stage, speaker cables and cabinets.
23. MAIN POWER ON/OFF SWITCH
24. AC INPUT
AC (IEC) SOCKET can plug in from 100 VOLTS to 240 VOLTS.

OPERATION & POSITIONING
TURN THE VOLUME DOWN on the BP-800 before plugging in your instrument.
Connect the speaker or speakers to the BP-800. 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 distorng and the overload indicator is on, TURN
DOWN THE VOLUME CONTROL!
The BP-800 amplifier is rated as 800 was into 4 ohms but that does not mean it is
the maximum output power. This is the output power without audible distoron.
Hard driving the BP-800 can cause it to put over power beyond 1000 was with
distoron. It is always a good idea to have speaker power handling to be double the
amplifier power rang. 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 resulng in greater
transparency of sound and less noise. Using this cable will give a richer tone to your
instrument.
ALWAYS USE A HIGH QUALITY GROUNDED AC POWER CABLE. NEVER USE THIS
AMPLIFIER WITH THE GROUND CONNECTION REMOVED.
TRANSPORTING AND STORING THE BP-800
When Storing:
• Keep in a dry locaon preferably at room temperature in the gig bag.
• 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 condion.
• Do not leave the BP-800 permanently connected to a power source.
Transporng
Always use a protecve case, gig bag or cover to prevent damage.
