DESCRIPTION
Both models in this PC Series are completely factory assembled
utilizing an eight inch (15 watt program) driver specifically designed
for low level (0.5 to 6 watt) distributed sound systems. This driver in
conjunction with its associated baffle (grille) will provide uniform
dispersion characteristics over a broad frequency range.

The dual (25 and 70 volt) line transformer has a high saturation

response characteristics will not be impaired by saturation. The dual
voltage feature allows the convenience of one model for all line
voltage applications.
voltage applications.
The ‘V’ suffix model has a center baffle mounted, screw driver
adjustable Volume Control. TOA design engineers devised this
control to withstand heat, fumes and contaminants that are
associated with ceiling mount installations. This durable,
conservatively designed volume control will provide a long, noise
free service life. The control shaft is provided without a knob to
prevent unauthorized tampering. Its slotted end allows the
technician to quickly balance system levels without high labor costs.
Both PC models have a nominal 2½ inch (behind the grille) depth
which will allow mounting in most partitions, walls and other
shallow spaces. Mounting holes conform to most standard back
boxes. Assembly components are not separately available.
