The TOA A-9240SHM2CU is a 2U rack-mount digital matrix mixer and power amplifier built for permanent installation in commercial facilities, corporate environments, houses of worship, education campuses, and public address systems. Its modular architecture accepts TOA 9000M2 series and legacy 900 series input modules, allowing integrators to tailor the signal chain to the specific demands of each project without committing to a fixed I/O count at purchase. With a single 240W power amplifier channel running at 70V, the unit is well-suited for distributed speaker systems covering multiple zones from one rack space.

For systems integrators, the A-9240SHM2CU reduces rack complexity by consolidating DSP, routing, and amplification into a single chassis. Onboard parametric EQ with 30 TOA loudspeaker presets, high-pass and low-pass filters, compressor control, and up to 40ms of delay provide the processing depth needed to tune an installation without an external DSP. RS-232C connectivity enables direct integration with AMX and Crestron control systems, and four contact closure inputs and outputs support basic trigger-based automation. Scene and paging memories simplify day-to-day operation for non-technical staff. Settings are stored internally and recalled from the front panel, making the unit straightforward to hand off after commissioning.
