Service Manual
Tips and Troubleshooting
As printed in the User Guide
For your safety do not remove the
EARTH
(ground) connection in the power lead of the
console or connected equipment.
☺
Have your
MAINS SYSTEM
checked by a
qualified electrician. If the earthing is solid to
start with you are less likely to experience
problems.
☺
Use high grade
AUDIO CABLES
and
check them for reliable connection. It is well
known that many audio system problems are
due to faulty cables and connectors.
In a club or similar installation strict
SOUND LEVEL
and noise regulations may
apply. Check that your system levels are
correctly set up to comply.
To avoid damage to your hearing start with
the
HEADPHONES
level control at minimum
and turn up only as much as is needed to
maintain comfortable listening level. Do not
drive headphones at high listening levels for
long periods of time.
Always switch connected
AMPLIFIERS
on last and off first to avoid thumps when the
console and connected equipment is turned on
or off.
Reduce level if the red meter
PEAK
led
flashes. These warn you that you are near
clipping which may result in system overload
and distortion. The
XONE:02
provides plenty of
drive and headroom when operated around the
0 to +6 meter points. Check that the amplifier /
speaker system is correctly matched and set up
for correct levels.
☺
If you suspect a console fault
. The
console is the heart of the audio system and is
often suspected faulty when a problem occurs.
Usually the fault is found to be with other
equipment in the system, typically the
interconnecting leads, input sources, or level
matching between equipment. Check for source
problems by unplugging each channel in turn
listening for a change in symptom. To check the
console, isolate it by unplugging all sources and
outputs leaving just headphones and a
reference source such as a CD player
connected.
?
I have plugged in a microphone but it
does not work
. The
XONE:02
is designed to
operate with non-phantom powered dynamic
microphones such as the popular vocal types.
Do not use microphones which require phantom
power. If it has an on/off switch check that it is
turned on. Make sure the front panel LEVEL
control is turned up and MIC ON switch pressed.
?
The signal sounds very distorted with
high level and excessive bass
. Only plug
turntables needing RIAA equalisation into the
PHONO inputs with RIAA selected.
?
There is a hum on the turntable channels
.
Check that the turntable earth strap has been
correctly connected to the console chassis earth
post. Also check that the turntable headshell
and cartridge are correctly aligned and plugged
in.
?
The MIX meters reads fine but the signal
is distorted
. Switch the meters to CUE and
check that the channels are not peaking red. If
they are, the output meter may still read fine if
the fader or master level control is not set fully
up. Reduce the input level control if the channel
meter reads too high.
?
Only one side of the stereo mix is
working
. Check that the VCA PAN control is
not set fully to either L or R. Also check for bad
connections, in particular RCA phono leads and
turntable headshell and cartridge pins.
?
The channel is not working
. Check that
the TRANSFORM switch is not selected. This
mutes the channel.
?
There is feedback
. Check that the
microphone is not placed next to the
headphones or loudspeakers. The mic may pick
up its own signal and feed back. Use the mic
EQ to tune out the range of frequencies likely to
feed back. In loud listening conditions feedback
can sometimes be caused by mechanical
vibration through the turntables into the
cartridge, or even the needle resting on a cued
turntable starting to resonate in the groove of the
record.
?
The crossfader works backwards
. Check
that the reverse switch has not been pressed
and its red LED on. If it is off then check that the
crossfader has been re-fitted the right way round
if previously removed.
?
I have connected a stereo source to a
single input using a Y-adapter but it sounds
bad
. Do not connect more than one output to
the input. These adapters are designed to feed
one output to two inputs, not the other way
round.
?
The level changes when I switch in the
effects
. The effects loop operates at 0dBu line
level. Make sure the external effects device is
set for similar line level and 0dB unity gain.
?
I can hear interference pickup in the mix
.
If you are not using the LINK IN sockets then
make sure the shorting plugs supplied with the
console are plugged in. These short out the
inputs to prevent interference when not in use.
