Suggested Settings
Before we look at some s
uggested
settings there are a couple of points
that you should remember ;
1 / Taste in sound is a very
personal thing. What might sound
great to one bass player might not
appeal to another bassist. Therefore
these suggested settings may need
some alterations to suit your own
personal taste.
2 / One of the main influences on
your sound will be your bass. Each
bass displays certain tonal
characteristics, some for example
will sound brighter than others
while others may sound bassier. For
this reason again you may find that
these suggested settings need some
alteration to give the required sound.
Here then follows three simple
settings for the B150 for slap,
fingers and plectrum styles. We
hope that these settings provide you
with a useful starting point to
develop your own killer bass tones.
Please Note : Gain and Volume
should be adjusted to taste.

15. FX Return
For connection from the output of an external
effects processor or floor pedal.
16. Line Out
The Line Out Jack can be used for connection to
home recording equipment for direct recording.
17. D.I. Output with Earth Lift Switch
The D.I. Output is designed for connection to
professional recording or P.A. equipment.
Connecting a piece of audio electrical equipment
which has been earthed to another piece of earthed
electrical equipment, such as an amplifier and
recording equipment, can result in a background
hum. Should this problem occur, the B150 features
an Earth Lift Switch which when used will alleviate
the hum.
18. Power Switch
On/off mains power switch for the B150 with
LED to indicate when on.
B150
Rear Panel Features
1. Mains Input
For connection to the mains. Always ensure that
a good quality mains lead is used and that the plug is
wired in accordance with the regulations of your
country.
The rear panel of the B150 features air vents to
keep the amplifier cool. Care should be taken to
ensure that these vents do not become obstructed
while the amplifier is in use.
