8.3 HIGH EQ
The High control of the BiX is fixed at with a 2kHz or 4kHz
transition frequency, with a gain range of -15 to +15dB. Again,
this is a fixed shelving type control, which means everything
above the selected transition frequency is boosted or cut.
Otherwise known as the treble knob. If you think your banjo
may be too bright (which it probably is), turn this knob
counterclockwise. If you think your electric 2 string gourd
needs a little more bite, turn this knob clockwise. If you’re not
sure, start turning it one way or the other until it sounds better.

8.4 EQ BASICS
With such a simple EQ section, it’s easy to make quick, broad
adjustments to you instrument’s signal. You won’t really
be able to chase down and make surgical adjustments to a
particular trouble spot, but you’ll find with a little practice you
can easily adjust your tone in a useful way. If your instrument
really requires a more surgical approach (i.e. parametric EQ
control), you can easily insert one into the FX loop.
Here’s a couple of tips for getting a sound you like quickly:
Is your instrument:
Too bright or shrill?
Turn down the HIGH
Too dull or dark?
Turn up the HIGH
Too thin?
Turn up the LOW
Too bassy?
Turn down the LOW
Want more mids?
Turn down the HIGH and LOW controls
and turn up the Gain
Want less mids?
Turn up the HIGH and LOW controls
and turn down the Gain
Further EQ adjustments can be made by the DIP switch
controls on the rearpanel. These settings are explained in the
following section.
8.5 DIP SWITCH CONTROLS
These are small switches (located on the rear panel) and
are designed to be hard to move so they don’t become
inadvertently switched. To move them, use the tip of a guitar
pick, car key or something pointy enough to move it up
and down. Unless you are given to lavishly ample pedicure
tendencies, your fingernail may or may not work. Just be
careful not to use something too sharp as to booger up the
switch.
They select the following:
1. GROUND: Selects between ground (gnd) / ground
lift (iso) for the DI output. Use this switch if you are
experiencing a buzzy, unwanted ground noise on your
signal. This will be due do a ground loop somewhere in
your setup between the BiX and other equipment, amps,
mixer etc… If lifting the ground here does not remedy the
problem, you will need to try to lift the ground of other
equipment in your setup.
2. EQ low freq: Selects between the 2 available Low EQ
transition frequencies – 100Hz (low setting) and 200Hz
(high setting). These numbers represent the point at
which the Low EQ filter is at half of its peak gain. These
settings let you voice the EQ’s performance to your
particular instrument. For example, a Bass may benefit
from EQ control in the lower part of the frequency
spectrum, in which case the 100Hz setting would be
best. Or if you have a fiddle which has very little sound
below 200Hz, the 200Hz setting will be better making
adjustments to the low end of the instrument.

3. EQ high freq: Selects between the 2 available High EQ
transition frequencies – 2kHz (low setting) and 4kHz
(high setting). These numbers represent the point at
which the high EQ filter is at half of its peak gain. So these
2 settings effectively let you voice the EQ’s performance
to your particular instrument. For example, an instrument
with particular EQ needs around and above the 2kHz
range may benefit from EQ control in the lower part of the
frequency spectrum – for an instrument that needs more
cut or boost of upper mids. Or use the 4kHz setting to only
tailor the higher frequencies of an instrument.

As with all EQ settings, the more you know about what
your instrument needs the better off you will be making
adjustments on the fly. We recommend you get to know these
