Professional-Grade Power Amplification for Installed Sound Systems
The TOA P-906MK2 is a 60-watt single-channel power amplifier designed for highly reliable operation in commercial and industrial environments. As part of the legendary TOA 900 Series, this amplifier is ideal for paging, background/foreground music distribution, and music/message-on-hold applications in airports, hospitals, factories, schools, and other public venues.
Renowned for its long-term reliability, the TOA 900 Series has set the standard in installed sound system amplification. The P-906MK2, along with its higher-output siblings — P-912MK2 (120W) and P-924MK2 (240W) — delivers exceptional audio quality with wide frequency response, low noise, minimal distortion, and excellent output regulation.
The P-906MK2 supports both transformer-isolated (25V, 70V, 8Ω) and direct low-impedance outputs, giving system designers unmatched flexibility. A plug-in module slot accepts a wide range of TOA modules for custom functionality — including mic/line input, remote volume control, mute send/receive, and more.
