GUITAR RIG KONTROL Hardware Reference – 41
7.1.3 Noise
Audible hum can have several reasons, some of which are listed below:
►
Single-coil pickups are prone to collecting electrical interferences. Humbucker pickups
produce much less hum, which is why they got their name.
►
Your guitar is too close to electrical equipment. To reduce this type of hum, move the
guitar further away from the equipment.
►
The guitar’s volume knob is set to a low level. Turn the knob up. If your guitar has
more than one volume knob, make sure to check all knobs.
►
You are using a non-shielded or broken guitar cable. Your guitar’s shielding may also be
insufcient. Try replacing the cable with a shielded model rst. If this does not help, you
should consider having your guitar’s electronics serviced and shielded by a professional.
If you are experiencing hiss, the input level at the RIG KONTROL preamp might be too
low. Turn up the instrument’s volume or increase the input level on the RIG KONTROL.
For more information on setting the input level, see section 4.4 (Windows XP/ Windows
Vista) or section 5.4 (Mac OS X) of this manual.
7.1.4 Ground Loops
Ground loops (usually perceived as a hum or buzz) are a common problem when multiple
electrical devices are connected to the same power circuit. The following steps should
help to eliminate them:
►
Disconnect all devices that you are not currently using, e.g. peripheral devices you
may have connected to your computer (external data storage, CD burners).
►
Hook up a DI box behind the RIG KONTROL outputs. Most of these boxes have a
ground lift switch, which allows breaking the ground loop and eliminating the noise.
