Overview
Just like its predecessor (the DLC-250.4), the DLC-250.4d is small but mighty and it’s now even mightier with the addition of Dante and AES67. Capable of delivering 250W into 4, 8, and 16-ohms from any channel pair, or 125W into 4, 8 or 16-ohms all channels driven, this little 6.5lb., one-half rack loudspeaker controller packs a punch into minimal rack space. If that weren’t enough, the DLC-250.4d can drive 70V/100V hi-Z loudspeakers direct - no internal transformer required.
The DLC-250.4d is equipped with Dante / AES67 audio-over-IP digital I/O making setting up and deploying even complex distributed audio systems painless and bullet-proof. No bulky analog audio cables are required.
The DLC-250.4d can drive up to 16 Theory 16-ohm loudspeakers in Lo-Z mode, or up to 64 in Hi-Z mode - all from a half rack chassis!
The DLC loudspeaker controllers from Theory can be configured via its on-board web interface accessible via wired Ethernet, or via its on-board Wifi access point and includes matrix mixing, priority audio routing and ducking, parametric EQ, delay, gain and limiter DSP objects to make system optimization easy.
Full API and modules for AMX, Control4, Crestron, Crestron Home, ELAN, Q-SYS, and RTI available.
