Phil Jones Bass BP-800 User manual

BP-800
OWNER’S MANUAL
Thank you for purchasing the BP=800 bass amp. A great deal of dedication and passion went into
designing and building this no-compromise, high performance compact 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 BP-800 AMPLIFIER
The BP-800 is a high power 800 watt D-Class power amplifier and a pure class A single channel pre-
amplifier housed in a machined aluminum enclosure.
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 5-Band EQ for total tonal control of instrument.
• Auxiliary input for other audio sources with volume control.
• Headphone out jack.
• Easier to see, Larger master volume control knob.
• Balanced line out with per/post EQ and ground lift switches.
• Power amp input (Line In jack).
• Pre amp output (Line Out jack).
• FX send/return jacks.
• Neutrik NL4 Speakon out, high-current socket.
• Main Power on/off switch.
• IEC AC input 100-240 volts AC.( Operates on all world voltages).
PANEL OVERVIEW

1. POWER ON INDICATOR
Auto standby function:
When connected to AC power, turn on the power, the power LED will light up with
red, that shows the amplifier is in standby mode.Under standby mode, when the
input socket have a signal was more than 20mV, the power LED will turn green,
that shows the amplifier is working.
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 connecting 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.
25. COOLING FAN
Always allow space to let air circulate through amplifier.
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-04 speaker cable for amplifier to cabinet, as it has
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-800 amplifier is rated as 800 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-800 can cause it to put over power
beyond 1000 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.
ALWAYS USE A HIGH QUALITY GROUNDED AC POWER CABLE. NEVER USE THIS AMPLIFIER WITH THE GROUND
CONNECTION REMOVED.
TRANSPORTING AND STORING THE BP-800
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.
• Do not leave the BP-800 permanently connected to a power source.
Transporting
We recommend to use a protective case, gig bag or cover to prevent damage.
