The PLC-9K4 delivers 9000W in a 17-pound, 1U chassis. Capable of delivering 900W into 16-ohms (symmetrical and asymmetrical channel loading), and 1600W into 8-ohms (symmetrical and asymmetrical channel loading), 2000W into 70V, and 2-ohms (symmetrical), 2250W into 100V and 4-ohms (symmetrical), 2500W into 70V and 2-ohms (asymmetrical), 3200W into 100V (symmetrical) and 4-ohms (asymmetrical), 4000W into bridged pair 4-ohms (symmetrical) and 4500W into bridged pair 8-ohms (symmetrical), this loudspeaker controller packs new levels of power into minimal rack space.

The PLC-9K4 is equipped with 4-channels of Dante / AES67 audio-over-IP digital I/O via 3 configurable network ports, including one PoE port. Each port can be configured for audio-only, control-only or dual operation.

The PLC-9K4 can drive up to 32 Theory 16-ohm loudspeakers in Lo-Z mode, or over 400 (!) in Hi-Z mode. You read that right, 400+ Theory speakers from a 1U chassis!

The PLC loudspeaker controllers are deployed within Powersoft Armonia+ System Configuration Software in the exact manner as Powersoft Unica amplifiers, so deploying a Theory PLC system is completely seamless within the already-familiar Armonia+ workflow.

Full API and modules for popular control systems like Q-SYS™, Symetrix™, and Crestron are available.

KEY FEATURES:

1U 4-Channel Amplified Loudspeaker Controller with Dante & AES67
Based on Powersoft Unica™ Platform
Seamless System Setup within Powersoft Armonia+ System Configuration Software
Cloud-based Control and Monitoring via Powersoft MyUniverso™ 2.0
Proprietary Theory Loudspeaker Presets for All Models
4× 2250W; Total Power: 9000W
Drives LoZ and 70V/100V on all channels
3 Configurable 1Gb Network Ports w 1x PoE
Easy Swap USB Key Amplifier Restore
All-Channel Power Sharing

AVAILABLE SOON! - JUNE 2026
