ControlSpace® EX-4ML
mic/GPIO Dante™ endpoint
Product Description
Optimized for use with the EX-1280C, the EX-4ML Dante™ endpoint,
is a convenient, cost eective solution for connecting up to 4
conferencing microphones over a single cat-5/6 cable. Whether
used under a conference table, daisy-chained with other EX or
endpoints, or standalone in a rack, the EX-4ML adds 4 high-quality
microphone/line inputs, 4 GPI, and 8 GPO to your networked audio
system. Autodiscovery, drag and drop programming, auto-routing,
and simplified logic control in ControlSpace® Designer™ make
configuring the EX-4ML easy. Tasks such as configuring microphone
LED status and microphone mute actions are greatly simplified within
ControlSpace Designer without requiring external control system
programming.
Key Features
• One-cable-from-the table connectivity supports PoE+, Dante™ audio
networking, logic I/O and LED power to maximize ease of integration
• Broad conference microphone compatibility with 4 high-quality
mic/line input channels, each featuring 48V phantom power, 12V
LED power, 1 logic input and 2 logic outputs for interfacing with
microphone pushbuttons and indicators
• Dante™ audio networking for connection to other Dante-enabled
products over Ethernet-based networks
• Dual network and power connectors allow daisy-chaining of multiple
EX endpoints
• Rotatable mounting tabs allow for multiple mounting options
• Low-profile aluminum enclosure with integrated LED indicators for
unobtrusive under-table mounting
• Simplified software configuration via ControlSpace Designer
software. Supports autodiscovery, auto-routing, and logic presets for
microphone LEDs and pushbuttons
• Optional installation accessories include a magnetic mounting plate
for single-handed under-table mounting, a microphone extension
cable, and a 60 W power supply
• Power and signal indicators
