Crown CTD-8125 Eight-Channel 125W Power Sharing Amplifier with DSP and Dante

The CTD-8125 is the eight-channel ComTech D amplifier, and it fits eight zones into a single rack unit. Every channel delivers 125W with all channels driven, into low impedance or into a 70V/100V distributed line, so a building with eight small rooms does not need eight separate amplifiers or a taller rack.

Power sharing works in two banks: channels 1 to 4 share 500W in any ratio, and channels 5 to 8 share another 500W. That is what lets one busy zone borrow headroom from three quiet ones instead of sizing every channel for the worst case. Dante inputs and outputs put the amplifier on the audio network directly, on-board DSP handles room and speaker tuning with factory JBL SpeakerTunings for supported models including the Control 400 Series, and setup runs in a browser with no proprietary software to install. HARMAN's HControl protocol talks natively to BSS OMNI processors and AMX MUSE controllers, and an API covers third-party control.
