Crown CTD-4125 Four-Channel 125W Power Sharing Amplifier with DSP and Dante

The CTD-4125 covers four zones from a chassis that takes half a rack space and one rack unit. Each of the four channels runs 125W with all channels driven, and power sharing lets a single channel reach 500W when its neighbours are idle, so a lobby, a bar, a patio and a main room can share one amplifier without sizing every channel for the loudest zone.

Dante inputs and outputs put the amplifier directly on an audio network, and DSP on board handles room and speaker tuning with factory JBL SpeakerTunings for supported cabinets. Outputs are switchable between low impedance and high impedance, so distributed 70V/100V lines and 8 Ohm pairs can live in the same rack, and configuration runs through a web UI over the network.
