Description The MixWizard4 12:2 from Allen & Heath is a versatile, all-purpose professional mixing console with 100mm faders. The console features 8 mic/line inputs with inserts and direct outputs, six auxiliary outputs, two full channel dual stereo inputs, two stereo returns and two built-in FX engines with 20 presets.Channels 1 through 8 feature mic/line inputs with balanced XLR and TRS jacks with 48V phantom power for plugging in microphones and instruments, each with a 4-band EQ with sweepable mids. They each also feature a peak indicator, -20dB pad, six aux send knobs, pan knob, channel mute and a high-pass filter that attenuates frequencies below 80Hz by 12dB per octave. The mixer also includes two channels with dual stereo inputs that can be used separately, mixed together, or split and routed so that one feeds the other.Channels 1 through 8 also feature inserts that can be used for inserting processing equipment into the signal chain such as compressors, outboard EQ and delay units. Furthermore, they each have direct outputs that can be sent to a multi-track hardware recorder or computer audio interface for tracking live performances. The console’s six aux sends use balanced TRS output jacks that can be used to feed stage monitors, outboard effects and other gear. In addition, the MixWizard4 12:2 is equipped with two stereo returns with TRS inputs that feature separate gain knobs. These allow for returns from outboard effects or input from external audio devices such as CD or MP3 players to be mixed to the stereo bus.Features19″ rack mountable8 mic/line inputs with balanced XLR/TRS jack, insert and direct output100mm fadersDedicated mono output fader – can be switched to provide an L R mono feed for a center or fill speaker, or sub bass feed6 aux sends – 2x pre fade / 2x switched / 2x post fadeL and R main outputs – XLR outputs with inserts2 stereo returnsIndependent A-B output for feeding 2-track recorders, monitor wedges and more4-band EQ with 2 swept midsTwin FX engines with 20 FX presetsTri-color, 12-segment bar graph metering 48V phantom powerFootswitch connector (mutes/unmutes the ST1 FX Return)Signal and peak LEDsLamp socketSpecificationsMixerNumber of Analog Input Channels12Number of Mic Preamps8Analog Output Channels1 x Stereo Master Output 1 x Mono Master Output 1 x Stereo Control Room/Monitor Output 6 x Mono Aux Send Output 8 x Mono Direct Output 1 x Stereo Headphone OutputMetersMain Meter: 12-Segment LED Channel Meter: 2-Segment LEDMeter RangeMain Meter: -30 dB to 16 dB Peak/Clip Channel Meter: -12 dB to 16 dB Peak/ClipMeter Calibration0 VU on Meter = 4 dBu at Main OutputSignal ProcessingGain/Trim RangeMic Input: -60 dB to 10 dBu Line Input: -40 dB to 10 dBu Stereo Input: -16 dB to 20 dBu Stereo Return: -6 dB to 20 dBu (Balanced) -2 dB to 20 dBu (Unbalanced)Input Pad-20 dBEQ ParametersMono Channels: High: ±15 dB at 12 kHz (Shelving) Hi-Mid: ±15 dB at 500 Hz to 15 kHz, 1.8 Q (Semi-Parametric) Lo-Mid: ±15 dB at 35 Hz to 1 kHz, 1.8 Q (Semi-Parametric) Low: ±15 dB at 80 Hz (Shelving) Stereo Channels: High: ±15 dB at 12 kHz (Shelving) Hi-Mid: ±15 dB at 2.5 kHz, 1.8 Q (Semi-Parametric) Lo-Mid: ±15 dB at 250 Hz, 1.8 Q (Semi-Parametric) Low: ±15 dB at 80 Hz (Shelving)FiltersInput Channels: High-Pass: 80 Hz, 12 dB/OctaveBuilt-In EffectsYesPerformanceHeadroomChannel:  21 dB Main Mix:  23 dBFrequency Response10 Hz to 30 kHz ±0.5 dBMax Input Level 30 dBu (Mono)Output LevelXLR Main Output: 4 dBu (Balanced, Nominal) 26 dBu (Balanced, Max) Aux Output: -2 dBu (Balanced, Nominal) 21 dBu (Balanced, Max) Direct Output: 0 dBu (Balanced, Nominal) 21 dBu (Balanced, Max) 1/4″ Alt Output: -2 dBu (Balanced, Nominal) 21 dBu (Balanced, Max)I/O ImpedanceMic/Line Input: 2 Kilohms (Pad Out) > 10 Kilohms (Pad In)<br /> <b>Stereo Input:</b><br /> > 10 Kilohms<br /> <b>Stereo Return:</b><br /> > 10 Kilohms (Balanced)<br /> > 2 Kilohms (Unbalanced)<br /> <b>Main Output:</b><br /> < 75 Ohms<br /> <b>Aux Output:</b><br /> < 75 Ohms<br /> <b>Direct Output:</b><br /> < 75 Ohms<br /> <b>Alt Output:</b><br /> < 75 Ohms 10 Kilohms (Pad In) Stereo Input: > 10 Kilohms<br /> <b>Stereo Return:</b><br /> > 10 Kilohms (Balanced)<br /> > 2 Kilohms (Unbalanced)<br /> <b>Main Output:</b><br /> < 75 Ohms<br /> <b>Aux Output:</b><br /> < 75 Ohms<br /> <b>Direct Output:</b><br /> < 75 Ohms 10 Kilohms Stereo Return: > 10 Kilohms (Balanced)<br /> > 2 Kilohms (Unbalanced)<br /> <b>Main Output:</b><br /> < 75 Ohms<br /> <b>Aux Output:</b><br /> < 75 Ohms 10 Kilohms (Balanced) > 2 Kilohms (Unbalanced)<br /> <b>Main Output:</b><br /> < 75 Ohms 2 Kilohms (Unbalanced) Main Output: Aux Output: Direct Output: Alt Output: Headphone Output: CrosstalkFader Off: EIN-127 dBNoise Floor SNR-99 dB (Residual Output Noise, RMS 22 Hz to 22 kHz) -87 dB (LR Unity Fader Mix Noise, RMS 22 Hz to 22 kHz)THD NConnectivityAnalog Inputs8 x XLR 3-Pin Balanced Mic Input 8 x 1/4″ TRS Balanced Line Input 4 x 1/4″ TRS Balanced Line Input (2 Stereo Pairs) 8 x 1/4″ TRS Balanced Stereo Input (4 Stereo Pairs) 8 x 1/4″ TRS Channel Insert 2 x 1/4″ TRS Main InsertAnalog Outputs2 x XLR 3-Pin Balanced Main Output 1 x XLR 3-Pin Balanced Main/Mono-Summed Output 1 x 1/4″ TRS Balanced Aux Output 8 x 1/4″ TRS Balanced Direct Output 2 x 1/4″ TRS Balanced Alt Output 1 x 1/4″ TRS Headphone OutputPhantom Power 48 V, Selectable On/OffPowerAC Input PowerUniversal: 100 to 240 VAC, 50 / 60 Hz (T 630 mA L 250 V)AC Power I/O1 x IECPower Consumption45 W (Maximum)Lamp Power12 VDCPhysicalRack MountableNoRackmount Size10 RUDimensions20 x 20.9 x 7.7″ / 507 x 530 x 194 mm (Desk-Mounted) 19 x 4.8 x 17.5″ / 483 x 122 x 444 mm (Rack-Mounted, with Underside Connectors) 19 x 7.6 x 19.6″ / 483 x 193 x 497 mm (Rack-Mounted, with Rear Connectors)Weight24 lb / 11 kgPackaging InfoPackage Weight30 lbBox Dimensions (LxWxH)24.5 x 23 x 13.5″
