Ω load. Even though it will operate into that low an
impedance load,
we do not recommend
a 2
Ω load for standard configuration. The 800 is designed to
work most efficiently and effectively into a 4
Ω to 8 Ω load configuration.
Front Panel Controls and Features
Note: Level Controls go from what the incoming signal level is, down to off. Gain Controls can
amplify the incoming signal level to a much higher level.

Main Signal Input Jack
The Main signal input is located on the left side of the front panel. It is a standard ¼
” jack configured
for monaural operation. The input impedance is 500K Ohms.
Please note:
The rear input jack
connection switches through the front input jack. They can each be used separately but not together
at the same time.
Mute To Tune
The Mute to Tune switch is green in the normal on or (out) position. When pressed in (Mute is
engaged) the switch will change color to red indicating the mute is engaged, and the audio signal is
no longer going to the output amplifier. The Tuning Jack on the rear panel retains signal. The DI will
not have signal present at its output when the Mute is engaged.
Gain Control
The Gain Control is used to match the amplifier to your bass and playing technique. Turn the Gain
Control up to the point at which the green set level LED comes on and flashes on the stronger notes.
That will set your signal level to be in the sweet spot in the gain chain. That will get you the best
sound and lowest noise combination.
Shape Control
The Shape Control is a complex curve that boosts low end, scoops out the low midrange and has a
genteel rise toward the treble frequencies. It is very handy for enhancing the tone curve for popping
or slapping. It also works well in the studio for giving you a quick way to change or shift to a different
tone emphas
i
s. Be careful not to over use it in live playing conditions as the mid scoop can make it
difficult to cut through if you use too much of the effect.
