FRONT PANEL FEATURES
Input Jacks
– Designed to accept a standard ¼ inch mono phone plug. For
best results use a high quality shielded cable to connect your instrument to
the amplifier. Two inputs are provided – one each for active and passive
basses. If your bass has a battery, use the active input.
NOTE: Batteries do wear out. So it’s a good idea to check the battery in
your bass before using your amp. Then, check it regularly (monthly) to make
sure it’s still good.
Gain Control
– Regulates the first gain stage of the preamplifier and
controls the amount of signal available to the system.
Three Band Tone Controls –
Divides the audio spectrum into three bands:
Bass, Mid, and Treble. The Bass and Treble controls are shelving type
filters. The Mid control is a band pass type filter. These controls give you a
broad general control of the tone shaping.
Effects Loop
– If you want to use outboard effects processors, use these
jacks to SEND to and RETURN from your effects. This loop is for use with
“rack mount” effects only. If you are using “stomp box” style boxes, plug
your bass into the effects box, and then from there into the Input.
Master Volume
– Controls the main stage sound level and the Head Phone
outputs.
Headphone Jack
– Accepts a standard ¼ inch stereo or mono headphone
plug. It can also be used as a Master Output send to slave another amplifier.
DC Indicator
– When lit, this blue LED shows the power supply is
operating, and your amplifier is ready to use.
Mains On/Off Switch
– This switch turns the system power ON or OFF.
