THE TOA 900 SERIES is widely recognized as the industry standard in installed sound system amplification. When reliability and performance are critical – such as in paging and music distribution for airport, hospital, and industrial sound systems – you can count on the TOA 900 Series to perform consistently, day in and day out.
The P-906MK2 (60 W), P-912MK2 (120 W), and P-924MK2 (240 W) Channel Power Amplifiers are engineered for high performance with wide frequency response, very low noise and distortion, and excellent output regulation. A single module slot allows you to easily configure custom configurations using TOA plug-in modules with an extensive array of features and connector types. Outputs include transformer-isolated 25 V, 70 V, and 8 ohm plus a direct low-impedance mode if non-transformer operation is required. Other features include a direct input, selectable input sensitivity, a low-cut switch, and protection circuitry. The 900 Series Power Amplifiers are UL and cUL Listed and carry a five-year warrant.
