PROFESSIONAL SOUND SPEAKER SYSTEM
Model F-5 us
General description
The Toa F-5 is a full-range, bass-reflex type speaker having a 4-inch
(10 cm) speaker with 10-watt power handling capacity. Small in size,
it can be easily mounted on the wall. Push terminals are provided on
the rear panel for high impedance applications. By changing the internal wire connection this speaker can also be used for low impedance applications.
Installation
Using the supplied wall mounting pattern for correct positioning, drive two wood screws
or anchor bolts into the wall surface to a head height of less than 0.3" (8mm). Then insert
two fixing holes on the speaker's rear c o ve r onto the screws or anchor bolts for mounting.
(The pattern is printed on a flap of the carton box containing this speaker.)

The F-5 is factory-preset to 10 watts (490 ohms). Follow the instructions below to change
the wattage.
Remove four screws on the rear and detach a baffle board from an enclosure.
Change the connection of a red input lead from the prewired tap to that of desired im-
pedance (wattage). In this event, tighten the connection.

For low impedance applications, remove a red lead and a black lead
connecting between the matching transformer and speaker unit. Then
connect both leads from the input terminal directly to the speaker unit.
(Connect the red lead to " + " terminal of the speaker unit.)
