15. PB200 1” TITANIUM HF DRIVER LEVEL CONTROL (ENCLOSURE)
In the back of the PB200 there is a small jack plate with a level knob for the HF Driver. This level
control adjusts the volume of the HF Driver and does not effect the 15” woofer.
The HF Driver level control is another way to increase or decrease the highs coming from your bass.
If more highs are desired, the HF Driver level can be turned up (clock wise), or turned off if a warmer
sound is desired.
Note: One thing to consider with the HF Driver volume is the direction
the cabinet is facing. Because the combo amplifier’s HF Driver is less
that two feet off the ground, the listeners seated in front of the amplifier
may be getting more of the HF Driver volume than you (the player) stand-
ing in front of the amplifier. So be conscious of the volume and direc-
tion of the HF Driver when adjusting.
16. PB200 SPEAKER CONNECTION (ENCLOSURE)
The 15” speaker cabinet is 8
Ω
and designed to handle 200 watts. This allows the cabinet to be plugged
into the bridge output of the PB200 (This should already be done from the factory). In using the bridge
output of the PB200, a full 160 watts will be delivered to the 8 ohm speaker.
If a case comes up where less power is needed or if the amplifier is too sensitive or loud, the combo
cabinet can be plugged into one of the other two jacks labeled 4 OHMS MIN. This will deliver 50 watts
at 8 ohms instead of 160 watts, reducing the power and sensitivity of the amplifier.

opened) and the amplifier runs as normal. The GATE control sets the amount of input signal required
before the gate opens. It is best to set this level with one hand on the bass strings not playing and then
turnning the gate level control to where the gate LED just comes on. Then start playing, if the gate does
not open fast enough, turn the GATE control counter clockwise until it feels comfortable. If the gate jumps
in and out of gating when not playing, turn the control clockwise until it stops. This may need to be
repeated several times until the desired gating action is achieved. Changing the level on your guitar will
affect the setting of the noise gate.
8. PB200 5 BAND POST SHAPE EQUALIZER
5 band’s of the GRAPHIC EQ have been custom shaped and selected for the bass guitar. The levels and
tonal shaping of each band are customized individually unlike a standard graphic EQ to increase its use-
fulness and sweeten the sound of each band. Here are some references for the individual sliders to help
relate the frequencies in hertz to perceived sounds.
• The 80Hz slider is for the ultra lows. Often used in the cut region to boost or reduce the low end.
• The 250 Hz slider is for the mid-low bass. The bass has a great deal of sound here, so this slider can
change the sound drastically. Slide it up and down to hear what you like.
• The 500Hz slider is for the mid-bass frequencies. Like the 250Hz silder, there is a great deal of bass
guitar here also.
• The 800Hz slider is for the bass guitar’s high mids. This is where the mids start to get snappy, but they
can also get honky.
• The 2KHz slider is for the bass guitar’s highs. The crispy high’s in slap bass playing start in the range
of this slider.
ADJUSTING THE GRAPHIC EQ SLIDERS:
The best way to use the GRAPHIC EQ is to set all the sliders to their center detent positions. When the
sliders are in this position, they do no affect the audio signal. After playing in this “flat” setting for a few
minutes, raise one silder (to boost) and play a broad range of notes to hear the change. Then lower the
same silder pass the center detent (to cut), play a few notes to hear the change and return the slider to
the center position. Try this with each silder to hear what they do, then go back and adjust them together
if needed for your sound.
9. POWER LED AND SWITCH
The power LED indicates when the amplifier is on and ready to use.
10. HEADPHONE/LINE OUT JACK
The 1/4” jack can be used for mono headphone or a line output to feed a mixer or power amp.
11. SEND JACK (EFFECTS LOOP)
The SEND jack is the output of the preamp. This jack, used in conjunction with the RETURN jack, makes
up the external effects loop. The SEND jack is designed to put out the proper level for the input of an
external effects processor.
12. RETURN JACK (EFFECTS LOOP)
The RETURN jack completes the effects loop in conjunction with the SEND jack. This jack is designed
to recieve signals from an external effects processor. When something is plugged into this jack it goes
directly into the power amp portion of the bass amplifier and breaks the connection between the bass
preamp and the internal power amp.
13. SPEAKER OUTPUT JACK(S)
The PB100 features 2 speaker output jacks designed for a single 8
Ω
speaker or a multiple of speak-
ers that are wired for a total impedance of 4 ohms.
The PB200 features 3 speaker output jacks. 2 jacks are label 4
Ω
MIN. which are driven by two separate
amps rated at 80 RMS watts each. You can use one or both of these jacks at the same time with loads as
low as 4 ohms delivering 80 watts each for a total power of 160 watts.
A third jack labeled BRIDGE 160W 8
Ω
MIN. takes the 2 internal power amps and ties them together to
produce a bridged amp delivering a total of 160 watts into 8
Ω
. In order to use this jack, nothing can be
plugged into either of the 4
Ω
jacks. If a 4 ohm speaker is used in the BRIDGE jack, the amp will go into
protect mode and shut down. If this happens, change the speaker to 8
Ω
.
14. AC POWER & FUSE
The detachable AC POWER CORD supplied is designed to operate with one type of voltage (the European
230V export model uses a CEE-7 plug cord set). Check the rear power cord label for the proper voltage.
Plug the cord into a grounded “3” prong” power source. No attempt should ever be made to defeat or
use the amp without the ground connected.
The FUSE is located internally above the AC connector cord. To check or replace the fuse, remove the
power cord. The fuse type is a 250V Fast Blow rated at 5A for 120V or 3A for 230V models.
