DLC-250.4d

Theory DLC-250.4d - amplified loudspeaker controller with Dante and AES67

The Theory DLC-250.4d is a compact, amplified loudspeaker controller designed for professional AV installations. It delivers 250W per channel at 4, 8, 16Ω and 70V/100V without requiring an internal transformer. With Dante and AES67 support, setting up distributed audio systems is fast and reliable – no bulky analog cables needed.

The DLC-250.4d can drive up to 16 Theory loudspeakers in Lo-Z mode or up to 64 in Hi-Z mode, all from a half-rack chassis. Its built-in web interface, accessible via Ethernet or Wi-Fi, enables full DSP configuration including mixing, priority routing, ducking, parametric EQ, delay, and limiters.

Compatible with AMX, Control4, Crestron, Crestron Home, ELAN, Q-SYS, and RTI, the DLC-250.4d is a versatile solution for AV integrators.
