PRO SERIES DL451
DL451 is a 3U 19" modular configurable rack mount I/O unit with provision for 3 DL4 Series interface cards and up to 24 audio inputs and 24 audio outputs. With two AES50 network ports and two Ethernet control ports providing dual redundancy, plus a MIDI Interface (In, Out, Thru), the DL451 is the ideal partner to all MIDAS PRO Series digital consoles, enabling a digital snake connection from Front of House to stage or to provide additional local I/O at the console mix position.
Modular Expansion Cards
Five DL4 Series card options are available for DL451:
DL441 - 8 Analogue Mic/Line Input Card with MIDAS Microphone Preamplifiers
DL442 - 8 Analogue Line Output Card
DL443 - Analogue 8 Input, 8 Output Card with ¼ " TRS Connectors
DL444 - Analogue 8 Input, 8 Output Card with MIDAS Microphone Preamplifiers and D-Type Connectors
DL452 - AES3 Digital 8 Input, 8 Output Card with Sample Rate Conversion
DL451 can accept up to 3 of these cards in any combination. The DLIO-BP blanking plate is also available as an accessory should not all card positions be populated.
Digital Audio Networking
SuperMAC (AES50-Compliant) digital audio networking technology from KLARK TEKNIK simultaneously provides high channel counts, ultra low and deterministic latencies, sample-synchronous and phase-aligned networked clock distribution, error detection and correction, network redundancy, and ease of deployment and use – to meet the demanding requirements of live concert touring.
DL451 is compatible with all MIDAS PRO Series digital consoles and audio system engines, as well as with any other 96 kHz-enabled AES50-equipped devices.
Remote Console or Front Panel Control
All configuration settings for DL451 can be set either remotely from the mixing console, or directly via the intuitive and easy to understand front panel. DL451 features a front panel LCD display with intuitive menu navigation for all configuration options with LED status indicators, which provide clear feedback of operational status over wide viewing angles and distances. Clear indication is provided showing power supply output rail condition and AES50 and Ethernet network connection status and activity.
External Control Ports
DL451 features two General Purpose (GPIO) 25-pin D-type connectors for external device control, one for inputs and the other for outputs, which are opto-isolated to ensure galvanic isolation and avoid ground loops. External trigger events received via the input port are relayed to the PRO Series control centre, and external devices can in turn be triggered from the output port in response to scene change messages inserted in the console automation show file running in the control centre. An industry-standard MIDI interface (In, Out, Thru) is also provided to send and receive MIDI messages which can also be used in conjunction with the control centre’s automation system.
Built for the Road
Featuring a rugged steel 3U rackmount enclosure, the DL451 is designed for the rigours of live concert touring. Premium Neutrik connectors are used to ensure reliable network connections, night after night.
Auto-ranging universal switch-mode power supply
DL451 features a universal power supply, which is auto-voltage sensing for use on a worldwide basis.
