Tips
Using your computer for both track replay and FX
The default configuration for the internal soundcard on the Xone:23C allows for two
stereo channels from the computer and two stereo channels back. The channels from
the computer are primarily used to replay audio files, and channel 1-2 to the computer
us used to record the main mix. Channels 3-4 to the computer are , by default,
connected to the mixers FX send output.
To configure the computer and mixer for both track replay and FX you need to
aggregate the mixer’s soundcard with the built-in soundcard on the computer. On a
Mac this is done in the Audio MIDI utility (see page 12) - on a PC you will need to
download and install the utility ASIO4ALL ( www.asio4all.com ).
Using a 3.5mm to RCA stereo jack lead, connect the headphone socket on the
computer to the FX return on the mixer. Download install the free demo of Ableton
Live ( www.ableton.com ) - and configure it for FX send/return - input to Ableton from
the mixer soundcard 3 - 4 and output to the computers headphone.
You can now play tracks into the mixer from your chosen DAW and use the effects in
Ableton via the mixers FX send/return.
No sound from mixer
Check that the unit is powered on, and that an audio signal is connected to a channel
input.
Check that the Input level controls are turned clockwise at least to the centre position
and that the music sources connected are in the correct inputs (Inputs 1 - 3 for
turntables, Inputs 2 - 4 for CD players).
Check that the EQ controls are in the centre position.
Turn On the Channel CUE switch and raise the input channel LEVEL control until you
see the meters displaying the music signal.
Raise the channel fader, and ensure that the crossfader is towards the channel that is
receiving the audio signal.
Turn up the MASTER, MONITOR or HEADPHONE level controls, depending on what
output your amplifier is connected to, or if you are monitoring through headphones.
External effects unit can’t be heard
Check that the Effects unit is connected correctly (see page 5) and switched on - the
SND on the rear panel of the mixer should be connected to the input socket on the
external effects unit, and the output from the effects unit should be connected to the
RTN.
Check that the EXT - ON switch is on (illuminated RED) and that the channel FILTER
switch is ON (illuminated BLUE).
Signal is loud and distorted
Check that you are using the correct input; i.e. don’t plug a CD player into the PHONO
input….
Adjust the channel input LEVEL so that the meters peak the +3 or +6 LEDs. If the red
+10 meter LED comes on, turn down the channel LEVEL control.
