FrontPanelFeatures
DualInputJacks–TheleftjackisdesignedforastandardSwitchcraft“280“¼inchplug,from
either a passive or active bass system. Passive systems have been around since the invention of
the electric bass, and active systems typically include a 9-volt battery inside the Bass, or use an
external supply, e.g., some Alembic models.
Thesecond¼inchplugcanbeusedintwoways,andbothinputscanbeutilizedatthesametime.
♦ Therstapplicationisasaline-levelmonoinsert.Theoutputfromanalternativesourcesuch
as a drum machine, CD/tape player, or even a mix from the PA can be added. Set the volume for
the second source using the remote controls. This can be used for practicing or live use.
♦ Thesecond¼jackcanalsobeusedtoprovideanoutputsignaltoyourtuner.NOTE:Sincethe
secondinputdoublesasasignalinput,theMuteSwitchwillkillbothinputs.
MuteSwitchwithLEDIndicator
Thispushbuttonmutestheinputsignal,withtheRedLEDlightingtoindicatemutedoperation.
Sincethesecondinput“tunerout”jackdoublesasaninput,itisalsomutedbytheMuteSwitch.
Gain/Limit with LED Indicator
This control sets the preamp gain of the amp, and sets how much limiting is done when the Limiter
Switch is pushed IN. The Gain Control works in conjunction with the Volume Control (the last
knobontheright).WhileyoumightthinkoftheVolumeControlasa“MasterVolume”itisnot.
Theampisdesignedtonotdistort.Ifyouwanta“FuzzBass”youshoulduseapedalinfrontofthe
amp, or through one of the Effects Loops (back panel).
Limit Switch
The Limiter is engaged when the Limit Switch is pushed IN. In this position, the Limiter will pre-
vent the input signal from exceeding a preset level and is adjusted by the Gain/Limit Control.
A limiter is used to squeeze the sound into a smaller dynamic range. It can be used to restrict
excessively loud signals from going through the amp, such as clicks, and pops when playing a “slap”
bass style. It is also used to “raise” the lower level signals to a higher level by “limiting” the higher
level signals. Its effect is similar to a compressor. But, while a compressor squeezes all the signals
continuously,
