THE TOA 900 SERIES are widely
recognized as the industry standard
in installed sound system amplifi-
cation. When reliability and per-
formance 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)
Single Channel Power Amplifiers
are engineered for high perform-
ance with wide frequency
response, very low noise and dis-
tortion, and excellent output reg-
ulation. 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,
low-cut switch and protection
circuitry.
The 900 Series Power Amplifiers
are UL and cUL Listed and carry a
five year warranty.
