OverviewThe ART MX624 Six Channel Stereo Mixer with Two Zone Outputs is a versatile rack mount mixer that combines six independent input channels and routes them to two stereo zone outputs.The first channel can be used to control, via a front-panel switch, a ducking feature for all other channels making it an ideal solution for paging systems. All six channels can accept unbalanced stereo line-level signals. 48v phantom power can be independently assigned for each mic channel. Each channel has independent level controls and can be independently routed to either zone output, both or neither. Separate level, bass and treble controls adjust the sound of each zone output. Two bus inputs allow patching of multiple units when more input channels are needed.The ART MX624 may be used on stage, in the studio, or for permanent install applications including conference rooms, corporate boardrooms, churches, restaurants, small clubs, health clubs and more. A built-in power supply and single high 19-inch rack mount format allows for easy installation and reliable long-term operation.Key FeaturesSix stereo input channels with individual level controls Balanced mono microphone XLRs available on the first three channels Selectable padding on mic inputs Full +48V low-noise phantom power independently switchable for each mic input First channel provides switchable ducking of other channels with selectable parameters Front panel 1/8-inch stereo (TRS) mini-phone plug for portable music player input Two sets of left and right 1/4-inch TS main output jacks with master level, bass and treble controls Two bus input 1/4-inch TRS jacks allow units to be chained to provide extra inputs Rugged 1U rack-mount steel chassis with built-in power supplySpecificationsInput Connections XLR female balanced (Mic, channels 1-3)RCA unbalanced (Line Inputs 1-6, Left & Right)1/4-inch TRS unbalanced stereo (Bus Inputs, Zone 1 & 2)Output Connections 1/4-inch TS unbalanced (Zone 1 & 2 Out, Left & Right)Input Impedance 4k Ω (Mic), 10k Ω (Line), 10k Ω (Bus)Output Impedance 200 Ω (Zone 1 & 2)Frequency Response 20 Hz – 20 kHz (+0, -1 dB) (channels 1-6 in, zone out)Total Harmonic Distortion <0.01% @ 1 kHz, typicalPhase Response All connections are phase coherentSignal to Noise Ratio >90 dB typical (Ref 0dBu)CMRR >43 dB typicalMaximum Input Level -4 dBu, +16 dBu with 20 dB pad (Mic), >25 dBu (Line)Maximum Output Level +20 dBu (unbalanced)Maximum Gain 57 dB (Mic), 31 dB (Line)Ducking Threshold -49.5 dBv (adjustable via rear-panel dipswitches)Ducking Depth 15 dBTone Controls +/-12 dB @ 100 Hz & 10 kHzPhantom Power Switch selectable, +48V DC (regulated and filtered), 7 mA current limiting per legPower Requirements USA: 85-125 VAC, 50-60 Hz, <15WExport units configured for country of destinationDimensions 1.75″H x 19″W x 6″D (44.5mm x 483mm x 152mm)Weight 4.9 lbs (2.2 kg)
