to be changed, refer servicing to qualified service personnel who should refer to the
table below. The green/yellow wire shall be connected directly to the unit's chassis.

WARNING: If the ground is defeated, certain fault conditions in the unit or in the
system to which it is connected can result in full line voltage between chassis and
earth ground. Severe injury or death can then result if the chassis and earth ground are
touched simultaneously.

U.K. MAINS PLUG WARNING

A moulded mains plug that has been cut off from the cord is unsafe. Discard the mains
plug at a suitable disposal facility.NEVER UNDER ANY CIRCUMSTANCES

SHOULD YOU INSERT A DAMAGED OR CUT MAINS PLUG INTO A 13

Quick Start

For those of you who prefer to burn now and read later, we've included this Quick Start section to get you up and running.

Connect Cables:

Connect your bass into the INPUT (located on the rear of the BP-8 Valve). Now run from the OUTPUT(S) of the BP-8 Valve (either Left/Low or
Left and Right/High) to the input of either the bass amp, power amp or mixing board. Using both Left and Right outputs to run into either two
amplifiers or mixing board utilizes the stereo effects capabilities or the special Bi-Amping output available in the BP-8.

Apply Power:

Note: When applying power to the BP-8 Valve, it is recommended that the <OUTPUT> knob be turned down prior to powering up the unit.

Adjust Input

The <INPUT> knob is used to set the amount of signal that is entering the BP-8. It is recommended that the input level be set so that the

<SIGNAL/COMP> LED constantly lights while playing and the <CLIP> LED lights only with the strongest signals.

Adjust Output:

Now adjust the <OUTPUT > level knob of the BP-8 Valve to the desired output level.

Select Preset:

Begin playing your bass and choose any preset by either pressing the Value <UP> or <DOWN> buttons or by pressing the Program/Bank
<UP> or <DOWN> footswitches.

A Quick Tour of the BP-8 Valve

The Front Panel

1) Pedalboard - The BP-8 Valve’s pedalboard consists of six footswitches. The two mode footswitches to the right of the Parameter Matrix

allow you to change from Program mode to Bank mode by pressing the <UP> & <DOWN> footswitches simultaneously. When changing
modes, the appropriate LED will light to indicate whether you are in Program mode or Bank mode. In Program mode, the <UP> and
<DOWN> footswitches allow you to move through Programs, while the four main switches, labeled <1 - 4>, act as toggle On/Off
switches for Compressor, Preamp, EQ, and Mod/Pitch. In Bank mode, the <UP> and <DOWN> footswitches allow you to move through
Banks, while the <1-4> footswitches are used to select Programs. If footswitches <1> and <2> are pressed simultaneously, Tuner mode
will be activated. If footswitches <2> and <3> are pressed simultaneously, the Notch Filter

is selected for editing. If footswitches <3>

and <4> are pressed simultaneously, Bypass mode will be activated.

2) Parameter Matrix - The Parameter Matrix consists of a horizontal group of Effect LEDs and a vertical group of Parameter LEDs. The Effect

LEDs are: Compressor, Preamp, Equalizer, Noise Gate, Wah, Mod/Pitch, Delay and Reverb. This matrix shows you exactly what effects and
parameters are in use.

3) Display Window - The display window shows all current operating and programming information and is comprised of two parts: the

numeric LED displays and the Signal, Clip, and Store indicator LEDs. The first numeric LED in the display window indicates whether you
are in a User (U) or Factory Bank (F). The second and third numeric LEDs indicate the Bank number currently in use, and the fourth
indicates which Program number is currently in use. These numbers change as you scroll through the available Programs. The functions of
the Signal, Clip, and Store indicator LEDs are as follows:

• Signal/Comp - A green LED indicates signal is present in the BP-8 Valve. A yellow LED indicates the signal is being compressed by the

Compressor and can be adjusted by the Compressor’s Threshold parameter.

• Clip - Indicates analog clipping in the BP-8 Valve. Digital clipping can be detected when the third vertical LED from the top of the

Parameter Matrix flashes. Distortion may be heard in the output signal if either analog or digital clipping occurs. If analog clipping occurs,
