5.0 POSSIBLE ERROR SOURCES/
TROUBLE-SHOOTING
The
BassKick
is not getting any power:
-
Check the mains cable to see if it is connected properly.
-
The mains fuse is defective. Replace the fuse with another
identical fuse. If this fuse also blows, consult your Hughes
&
Kettner dealer.
The
BassKick
is connected properly, but no sound is
audible.
-
The GAIN and/or MASTER controls are turned all the way
down. Dial in a higher setting.
-
You have patched in an effects processor and you either
connected the cords incorrectly or the device is off. Check
out the FX signal chain.
-
You have plugged into the headphones jack, which
automatically switches the internal speaker off. Disconnect
the headphones.
When accessed, the LINE OUT jack causes annoying hum.
-
The connected device’s input circuit is unbalanced and an
electrical or magnetic field is causing interference. Use a
balanced input or situate the cables to reduce interference to
a minimum.
-
The grounding of the connected devices are causing a
ground loop. Do not sever the ground of the connected
devices under any circumstances! Attempt to solve the
problem by severing the ground on one side of the balanced
cable you are using to connect the devices (line cable). If
this doesn’t eliminate the noise, you must ensure the
connection is galvanically separated by routing the signal
through a
DI
box.
You have patched the LINE OUT signal to a mixing console,
but the sound coming through the PA or recording device is
totally distorted.
-
The mixing console’s balanced input is not set to line level.
Set the level accordingly at the mixing console. If for some
reason this is not possible, patch the signal to an unbalanced
line input at the mixing console or use a connecting cable
featuring an integrated voltage divider (available from your
local dealer or PA service company).
BassKick 707 only:
The amp’s output level seems too low.
-
The overall impedance of the connected cabinets is well
above 4 ohms. In order to access the amp’s full output
power, connect an additional cabinet in parallel or have a
technician rewire the cabinet. Ensure the overall impedance
is never below 4 ohms.
-
A device connected to the effects loop is reducing the
signal level. Adjust the signal level via the device’s
input/output control.
BassKIck 505 only:
The amp’s output level seems too low.
-
A device connected to the effects loop is reducing the
signal level. Adjust the signal level via the device’s
input/output control.
-
If you have connected an additional 8-ohm cabinet and the
output level is still too low, you can patch the signal to an
additional power amp/cabinet system via the LINE OUT
jack.
