The TOA 800D Series mixer amplifier is engineered for systems integrators and AV professionals designing installed PA systems in schools, offices, retail environments, and commercial facilities. Each unit combines a full-featured input mixer with a Class D power amplifier stage, eliminating the need for separate components and reducing rack space without sacrificing control flexibility. With four balanced microphone inputs featuring switchable phantom power, two auxiliary inputs, and two expansion slots for 900 Series modules, the system supports up to eight inputs in a single rack unit. Both 70V high-impedance and low-impedance speaker outputs are available, making the amplifier compatible with distributed speaker systems as well as direct-drive installations. The series is available in 120W, 240W, and 480W output ratings to match the coverage demands of small conference rooms through large open-plan facilities.

Onboard DSP handles dynamic feedback filtering, three-band parametric speaker EQ, and input tone controls, reducing the need for outboard processing in typical installs. Assignable input priorities and a built-in defeatable pre-announce chime support structured paging workflows without additional equipment. A dedicated IP control protocol enables remote monitoring and management via a software application, giving facilities teams visibility into system status from a network connection. A PFC power supply and Class D amplification keep operating efficiency high under continuous use. The rack mount kit is included, and an optional MT-251H-Q output transformer supports 25V distributed systems where required.
