This is a used unit in excellent, working condition. It has lived in a rack, but rack is not includedThe Mackie DL32R delivers 32-channels of powerful digital mixing that is wirelessly controlled from your iPad. It features convenient direct-to-drive multi-track recording/playback and an ultra-compact 3RU rackmount design that lets you ditch the snake once and for all. Fully loaded with DSP on each of the 32 Onyx+™ mic pres and 28 busses, the DL32R provides the power needed for professional applications. The Mackie Master Fader™ control app offers intuitive control over everything, including the ability to digitally recall each and every setting for incredibly fast setup.Mackie DL32R Features:32-Channel Wireless Digital Mixer:32 Onyx+ recallable mic preamps with wireless control14 Fully-assignable XLR outputsStereo AES digital outputTotal recall of all settings3U Rackmount design ready for road or installCard slot for Dante Expansion Card (card sold separately)Wireless Mixing:Complete control from your iPadNo set FOH position - mix from anywherePersonal monitor mixing via iPad, iPhone or iPod TouchSupports up to 10 separate iOS devices at onceMultiple engineers can work from a single mixerDitch the snake - place the mixer anywhereMulti-Track Recording & Playback:32x32 USB 2.0 audio interface for Mac- or Windows-based PCs24x24 recording/playback direct to USB 2.0 hard driveWireless control over all direct-to-disk recording/playback functionsRecord the show for later mixdownPlay back intermission music and backing tracksPerform a virtual soundcheckAmazing recording interface for the studioUtilize Mac- or Windows-based audio plug-ins in a live environmentFully-Loaded DSP:36 input channels with 4-band PEQ + HPF, gate and compression32 stereo-linkable input channels4 stereo-linkable return channels28 output busses with 4-band PEQ + HPF/LFP, 31-band GEQ, comp/limiter and alignment delay14 stero-linkable aux sends6 stereo-linkable matrix busses6 stereo-linkable subgroupsMain L/R busses6 VCAs and 6 mute groups3 Stereo FX processors with dedicated sends and returnsFull I/O routing with A/B sources per channelModern and Vintage options per processorMaster Fader Control App:Intuitive and easy to masterFast navigation with view groups and overviewQuick setup with tons of factory and user-definable presetsAccess limiting prevents unwated adjustmentsComplete offline operationEasy and frequent updates via App StoreMackie DL32R Specifications:General Digital:Sample Rate:  48 kHzA/D/A Bit Depth:  24-bitSystem Latency - Analog Input > Main Bus > Analog Output:  1.5 ms0 dBFS Reference:  +22 dBuFrequency Response:All inputs to all outputs:  +/- 0, -1 dB, 20 Hz - 20 kHzDistortion (THD):Mic input to main output, 1 kHz, -1 dBFS:  < 0.005%Noise / Dynamic Range / Signal-to-Noise Ratio:Equivalent Input Noise (EIN), 150 Ohm Termination:  -128 dBuCrosstalk:Analog XLR input-input:  < -105 dB @ 1 kHz (min. gain), < -80 dB @ 1 kHz (max. gain)Analog XLR / TRS output-output:  < -100 dB @ 1 kHzSignal-to-Noise Ratio (ref +4 dBu, one channel and main fader at unity, A-weighted):  92 dBOutput Noise, Muted Output (A-weighted):  -90 dBuDynamic Range:Analog Input to Analog Output (one channel and main fader at unity, A-weighted):  109 dBAnalog Input (unity gain, to analog clipping, -60 dBFS signal, A-weighted):  111 dBAnalog Output (unity gain, to analog clipping, -60 dBFS signal, A-weighted):  111 dBCMRR:  > 70 dB @ 1 kHz (60 dB gain)Analog Inputs 1 - 32:Connectors:1 - 24:  XLR Balanced25 - 32:  Combo XLR / TRS BalancedXLR Mic Pre:  Onyx+Input Impedance:1 - 24:  3 kOhms25 - 32:  3 kOhms mic (XLR), 30 kOhms line (1/4" TRS)Max Input Level:XLR:  +21 dBu1/4" TRS:  +30 dBuGain (digitally controlled analog):XLR:  0 to 60 dB (3 dB steps)1/4" TRS:  -20 to 40 dB (3 dB steps)48V Phantom Power (XLR):  48 VDC, 10 mA max per mic, with up to 16 simultaneously. 5 mA max per mic, with up to 32 simultaneously.
