Allen & Heath XONE:4D Advanced Controller Interface

The mixer section is based on the award-winning Xone:92 and features 4 triple-input stereo channels, 3 band total kill EQ, 2 stereo effects sends, 2 VCF filters with LFO, VCA crossfader and dual-rail channel faders, DJ mic and cue monitoring system. The assignable LFO has an editable step-filter function, encouraging creative combinations of the tempo-detecting BPM counter and tap tempo. Each MIDI fader becomes a filter cut-off frequency, enabling users to “draw” their own tempo-locked LFO waveform. A new BPM section includes a 16-bit tempo detecting circuit, which constantly monitors the BPM and outputs a MIDI clock to help synchronize MIDI-controlled music replay software with external source program material. Stereo FX sends can be used with external equipment such as effects units and samplers and both FX sends can be routed to the USB audio system and sent to the PC. The FX2 hardware output can be switched to act as a Main Mix record output. MIDI controller The Xone:4D provides full control of external MIDI devices including the most sophisticated DJ performance computer environments. There are 105 MIDI controls on the mixer surface, and with the use of the shift function, they allow 227 mappable MIDI messages to be sent. The BPM counter provides MIDI start/stop and clock, while a fader pickup algorithm allows seamless movement between the layers. USB soundcard Xone:4D features a 20-channel USB2.0 soundcard, featuring 4 analogue stereo inputs and outputs, transmitting audio at up to 96kHz with 24 bit resolution. It uses USB to interface the mixer audio and MIDI to a PC where the sound may be manipulated in real time using any music software application. The soundcard also produces SPDIF, COAX and optical digital inputs and outputs. A low latency ASIO driver is provided for audio streaming between the 4D and PC, and each mixer channel has its own soundcard input routing switches, allowing flexible output to or from the PC.
