The installation package version of the MIDAS PRO9 Live Audio Mixing System is designed for live sound reinforcement such as in concert venues, theaters, houses of worship, broadcast, tours, and more. The system requires the Pro9 version of the MIDAS DL371 modular, upgradeable, remote DSP processing engine (sold separately) connected via Cat 5e cabling to a networked system of up to 11 discrete I/O devices depending on the user's specific I/O requirements. A redundant N+1 processing card can be added to the DL371 DSP engine as a backup, in the event that a card within the 371 fails. Live performance digital console control center with up to 88 simultaneous input channels 35 time-aligned and phase-coherent mix buses 40 bit floating point processing with 96 kHz sample rate HyperMAC and AES50 networking allows up to 288 inputs and 294 outputs @ 96 kHz sample rate HyperMAC router with 192 bidirectional channels over copper and optical fiber Provides dual redundant snake connection to DL371Pro6 Audio System Engine Snake connections up to 500 m with optical fiber or 100 m with CAT5/5e cable 10 VCA (variable control association) and 8 POPulation groups Up to 36 assignable 1/3 octave KLARK TEKNIK DN370 graphic equalizers Up to 8 multi-channel digital signal processing effects engines 29 MIDAS PRO motorized 100 mm faders 2 daylight viewable 15" full color TFT display screens Fully interpolated touch sensitive controls Optional wireless remote control with MIDAS MIXTENDER App for iPad* Three bay auto-ranging universal switch-mode power supplies with N+1 redundancy Designed and engineered in England Over 40 Years of audio mixing console R&D Comprehensive latency management Custom Interpolation algorithms Comprehensive automatic time alignment of audio 70 microseconds of latency per link (hop) via KLARK TEKNIK"S SuperMac implementation VCA and Population Groups VCA and POPulation groups both have assignable color coding and digital write-on buttons VCA Groups allow access to all the channel faders belonging to any of the VCA groups at the press of a switch POP (POPulation) groups can contain any combination of channels that you want to access instantly at the press of a switch VCA and POP Groups encourage the development of a mental picture, or "Mind Map", of the whole system Selecting a VCA or POP group will bring all of the members of that group to you, rather than you having to go looking for them Input channels can be viewed either by scrolling the input faders or by pressing the EXTEND button, which will populate the VCA faders with additional members of that POP group Equalization Fully interpolated controls 4-band parametric EQ 4 different filter types Dynamics Processing XL8 dynamics processing 4 different input compressor algorithms 5 different output compressor algorithms A wide choice of dynamics processing Surround Sound Quad 4-Channel - L-R front plus L-R rear LCRS 4-Channel - L-R-C plus single rear channel Quad 6-Channel - L-R-C plus sub plus L-R rear FX 40-bit floating-point audio processing Custom-designed FX processors Internal FX processors operate within MIDAS' automatic latency compensation Automation 1000 snap shot scenes Scene-specific routing Scene store and recall can be ''scoped'' MIDI inputs and outputs provided Software versions forward and backward compatible Show files compatible with any MIDAS digital console Patching 288 inputs x 294 outputs (max. capacity) point-to-point routing anywhere within the network 56 mic / line inputs with MIDAS mic preamps Up to 80 simultaneous-input processing channels 16 Group / Aux & 16 Matrix - 32 Mixes in ''monitor'' mode 35 sample-synchronous, phase-coherent mix buses Sample Synchronous Audio Uses automatic latency management system for internal processing and compensation for additional A/D & D/A conversions when connecting analog inserts to synchronize samples and insure phase coherency of the outputs Analog Potentiometers Uses analog potentiometers as opposed to mechanical encoders to access the processing algorithms Display Screens Features five high-resolution displays that remain visible even in direct sunlight to provide visual feedback for channel strips, system information, 3rd party applications Detail Panel Area Features a vertically-oriented channel strip layout with configurable controls and multicolor LCD channel select buttons Microphone Preamplifiers Uses discrete component design with a warmth similar to that found on the MIDAS XL3, XL4, and Heritage consoles with separate analog remote gain and digital trim controls for gain staging Navigation Mode FLIP Navigation: selecting an output flips the input fader to become the input channel that sends levels to the selected output FX Navigation: deploys a patched internal FX processor to the display screen and maps the ASSIGNABLE CONTROLS to the FX processor GEQ Navigation: selects an output which has a GEQ assigned and present the GEQ on the VCA faders MCA Navigation: deploys the MCA faders of a selected output to the VCA fader bank. In conjunction with Advanced mode, MCA navigation mode controls the contributions of their members to the currently selected bus. Areas A and B Facilitates dual operator use for two independent stereo solo systems with: 4-Channel Configurable "Area B" for dual operators Mixtender iPad App Provides wireless remote control for key functions of the console. The App automatically selects the right console type so there is no difficult setup procedure. With the app you can monitor ALL input and output metering simultaneously in real time, and you can remotely EQ any speaker mix with one of the console's on-board KLARK TEKNIK DN370 GEQs. The app also provides simple, fast local stage mix adjustment by accessing the consoles' MCA (Mix Control Association). Multiple iPads can be used simultaneously and each one can be locked to a single mix, so artists can create their own monitor mixes without changing any other console settings. The app is free to download from Apple's App Store Third Party System Integration Provides an Ethernet tunnel between the stage and mix position with additional bandwidth using HYPERMAC digital snakes, Cat 5e, and the fiber optic option for third party data transfer via standard Ethernet traffic, MIDI message, and GPIO (general Purpose Input and Output signaling) Compatible I/O Units DL251 Fixed Format I/O Unit DL252 Fixed Format I/O Unit DL351 Modular I/O unit DL431 Input Splitter unit DL441 Analog Input card DL442 Analog Output card DL443 TRS card DL444 D-Sub card DL451 Modular I/O unit DL452 AES/EBU card Compatible Accessories DN9331 - Graphic Controller DN9610 - AES50 Repeater DN9620 - AES50 Extender DN9650 - Network Bridge DN9696 - AES50 Audio Recorder
