Welcome to the The XONE:V6 is an audiophile rotary club mixer that sets a new quality benchmark. It is an echo of the earliest days of pro audio when pioneering individuals hand crafted outstanding products free from the constraints of cost and time. We revisited the basics of audio circuit design restoring the simple purity of a minimum signal path meticulously constructed from the finest discrete components.
Channel Controls INPUT 4 LINE PHONO 18 6 3 0 3 10 6 6 Input channels are provided. Each has switchable inputs for two stereo sources. CH1-4 provide line and phono (RIAA) inputs. CH5 and 6 feature valve preamps and have two switchable line sources each. All channels provide insert points for patching in additional equipment. Internal jumper options let you change the gain settings and switch out the RIAA equalisation.
INPUT 5 18 6 3 0 3 10 Level Adjusts the input sensitivity from fully off to its maximum +10dB gain. Correct use of this control makes it impossible to overload the input preamp. Adjust it so that the meter averages around ‘0’ with loudest peaks up to ‘+6’. Note that there are internal option jumpers to reduce the maximum gain available to +6 or 0dB.
Microphone Controls A DJ microphone can be plugged in. A professional quality balanced dynamic vocal type is recommended. Phantom power can be internally enabled if a condenser type is preferred. The mic can be switched into the master mix, booth mix, and routes to the cue monitor. An insert is available for patching in processors such as a limiter or compressor. 2.5kHz Mic on/off Switch the microphone into the master mix using the ON/OFF toggle switch.
LEFT MIX LEVEL Master Controls The Master is the main output that feeds the house sound system. An overall level control together with 2-band equaliser is provided. External processing equipment such as a limiter or house EQ can be inserted into the master mix signal path. Main meter Two lamp-illuminated moving coil VU meters display the left and right signals. The needle movement accurately follows the VU (volume unit) standard. It displays the average signal level.

Channel Connectors Each channel has two stereo inputs. CH1-4 provide line and RIAA inputs. CH5 and 6 provide two line inputs. L A L R LINE A R PHONO/ LINE L and R inputs RCA phono sockets. The PHONO input provides gain and RIAA equalisation for turntable cartridges. Note that CH1-4 have internal option jumpers to disable RIAA if you want to use the inputs for additional line sources. The LINE inputs have a maximum gain of +10dB to accept signals as low as -10dBu.
Microphone Connectors MIC INPUT The microphone input is used for the DJ microphone. A hi-pass filter is built in to reduce low frequency handling noise, popping and proximity effect. An insert point is provided for patching in processors such as a compressor. Mic input MIC INSERT Balanced XLR, pin 2 hot. Maximum gain available is +60dB. We recommend you use a rugged, professional grade, dynamic microphone specifically designed for the vocal application.
MASTER INSERT R MASTER OUT -2dBu Master Connectors The master mix to feed the house system is available on two pairs of sockets, XLR and TRS. A pre-EQ insert point is provided for patching in processors such as house equaliser and protection limiter. Insert Unbalanced TRS (stereo) jack wired tip = send, ring = return, sleeve = common ground. With nothing plugged in the signal is passed through internal switch contacts within the socket. The insert operates at -2dBu.
Booth and Record Connectors RECORD -10dBV L BOOTH The XLR booth output feeds the DJ’s booth amplifier / loudspeaker system. The record output can be used to make a stereo recording of the performance. Booth output Balanced XLR wired pin 2 hot. Output level is +10dBu when the BOOTH level control is fully clockwise and the VU meters read ‘0’. The booth output is not affected by the MASTER EQ or level control. Connect to the amplifier input or speaker processor if one is used.

Installing the Power Supply Unit To avoid damage to the power supply unit internal assemblies do not mount it on to any surface subject to resonance or vibration. For permanent fixing, screw or bolt the power unit to a vertical surface using 6x fixings as shown. This ensures optimum cooling and performance. The fixing holes are 5mm diameter. 256mm (10") 79mm (3 1/8") 202mm (8") 79mm (3 1/8") Check that the mains power switch is in its off (O) position. Plug in the IEC mains lead.

Installing the Console Rack mount The console fits into a standard 19” rack system taking up 4U height. Use 4x M6 bolts with plastic protective cups. These are usually supplied by the rack manufacturer. 441mm (17 3/8") Plinth mount The console can be mounted in a custom built plinth or other furniture. Use the cutting template detail shown here. The dimensions allow for the console cover fixing screws. Secure with 4x suitably long M6 bolts and nuts. Use protective cups to protect the console surface.
Grounding The connection to ground (earth) in an audio system is important for two reasons: • SAFETY - To protect the operator from high voltage electric shock, and • AUDIO PERFORMANCE - To minimise the effect of ground loops which result in audible hum and buzz, and to shield the audio signals from interference pickup.
To ensure safe and trouble-free operation we recommend the following: • Have your mains system checked by a qualified electrician If the supply grounding is solid to start with you are less likely to experience problems. • Do not remove the ground connection from the power unit mains plug The console chassis is connected to mains ground through the power cable to ensure your safety. Audio 0V is connected to the console chassis internally.
Wiring the Cables 26 XONE:V6 User Guide
Connector Types The XONE:V6 uses professional grade 3 pin XLR, 1/4" TRS jack and RCA PHONO sockets. The XLR connection should be used with balanced equipment such as microphones and feeds to balanced signal processors and amplifiers. This has 3 connector pins: Pin 1 = ground (screen), Pin 2 = signal hot (+), Pin 3 = signal cold (-). The male XLR is used for signal output, female for input. The INPUT and OUTPUT JACK connections can be used with balanced or unbalanced line level equipment.
Switching the Console On The XONE:V6 power unit has two mains voltage settings, 115230V and 100V AC. First check that the setting is correct for your local mains voltage. This is marked on the power unit rear panel. The 115-230V setting senses the mains voltage level within the 115 to 230V range and automatically configures the power circuit mains transformer using relays. MAINS INPUT V.
Operating Levels and Meters It is most important that the system level settings are correctly set. The best performance can only be achieved if the system levels are set within the normal operating range and not allowed to peak. Peaking simply results in signal distortion, not more volume. It is the specification of the amplifier and speaker system that sets the maximum volume that can be achieved. The human ear too can fool the operator into believing that more volume is needed.
Internal Option Jumpers The XONE:V6 provides several user accessible internal jumper options. These are for specialist application or user preference and should not normally be needed. The factory default settings should satisfy most applications. The jumpers are plug-on and can be reconfigured quickly. However, it is necessary to remove the console cover to access the internal circuit assemblies. This requires that the console be unplugged and removed from its installation furniture.
Input Channel Option Jumpers Plug on jumpers set the options required. Plug across the two pins to set. Plug on to just one pin to remove. This keeps the jumper available to be re-used later in the future if needed. +10, +6, 0dB GAIN RIAA / LINE JP3 JP1 JP2 JP5 JP6 JP8 JP7 JP4 JP9 JP10 INPUT PCB XONE:V6 User Guide RIAA disable CH1-4. For RIAA gain and equalisation JP2, JP3, JP4 and JP8 are fitted. This is the factory default setting.
Microphone Option Jumper JP2 JP1 A plug on jumper sets the option required. Plug across the two pins to set. Plug on to just one pin to remove. This keeps the jumper available to be re-used later in the future if needed. Phantom power 30V phantom power is disabled when JP1 is fitted. This is the factory default setting. Plug the jumper on to JP2 instead if you wish to turn phantom power on. WARNING Do not connect unbalanced sources or cables to the XLR input when phantom power is applied.
Master Option Jumpers Plug on jumpers set the options required. Plug across the two pins to set. Plug on to just one pin to remove. This keeps the jumper available to be re-used later in the future if needed. Master output level The output level with MASTER control at maximum position and VU meters reading ‘0’ is +4dBu with JP1 and JP2 fitted. This is the factory default setting. To change this to 0dBu remove JP1 and JP2. Access these jumpers from below the console.
VU Meter Bulb Replacement Each VU meter is illuminated using a filament bulb mounted in a clip behind the meter. The bulb is a long life type. If it needs to be replaced procede as follows: VU METER BULBS Unplug the cables and remove the console cover as described previously. Carefully unclip the old bulb. Press in the correct type replacement bulb. Refit the cover. It is best to replace both bulbs at the same time. This ensures that they both maintain similar life. Bulb type 12V 1.
