DESCRIPTION

MIXER
Each of the 4 channels can select one of 3 sources: phono, line or soundcard

audio as shown. RIAA phono preamps are available on channels 1, 2 and 3.

These may be changed to line input by resetting an internal jumper link if

required. Level may be adjusted over a +/- 10dB range if the signal reads too high

or low on the channel meters. The 3-band EQ provides a safe amount of boost

but full cut (kill) for dramatic effect. A mic input with level and 2-band EQ routes

direct to the main mix. The DJ cues the mix using headphones. The mix may be

added to the cue’d channel signal to help the DJ synchronise the beat.

FILTERS

The channel signal may be routed direct to the LR mix or through either of the

two analogue filters. These provide the characteristic Allen & Heath analogue

filter sound with combinations of 3 switched bands, swept frequency, resonance

and tap tempo LFO control. The VCA crossfader affects the filter path when

switched in.

FX LOOPS

Two FX sends are provided. FX1 may be switched pre or post fader, while FX2

is pre fader. The send is typically connected to an effects device or sampler, then

routed back to the mix via one of the two FX return inputs.

OUTPUTS
The balanced XLR mix output feeds the house sound system. The monitor

output follows the main mix and can provide a booth monitor, alternative zone or

recording feed.

BPM COUNTER

Displays the BPM (beats per minute) of a music track entered manually by tapping

a button in time to the music, or automatically by analysing the signal routed to it.

The signal may be routed from the main mix or from an individual channel via the

pre-fade FX2 mix so that the beat may be calculated and checked before the track

is routed to the mix.
The BPM counter outputs MIDI clock so that a slave device such as a hardware or

software sequencer can be synchronized to the timing of a track playing through

the Xone:4D. To aid synchronization the MIDI clock can be momentarily speeded

up or slowed down by operating the PUSH/PULL lever.

UV REACTIVE PAINT
The white artwork on the front panel of the Xone:4D uses a UV reactive layer

and will therefore glow under UV light to improve visibility in low level light

conditions.
