Product Overview
THE TOA 900 SERIES are 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-924MK2 (240W) Single Channel Power Amplifier is 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 25V, 70V and 8Ω plus a direct low-impedance mode if non-transformer operation is required.
Other features include a direct input, selectable input sensitivity, low-cut switch and protection circuitry.
The 900 Series Power Amplifiers are UL and cUL Listed and carry a five-year warranty.
