TOA Electronics F-160W - Manual (Page 5)

6. IMPEDANCE CHANGE (HIGH-IMPEDANCE MODELS ONLY)
Because the following models have a built-in matching transformer, connect them to the amplifier with a
high-impedance (70 or 100) line output.
F-160GM, F-160WM, F-160WP, F-240GM and F-240WM
Input impedance can be switched in five steps, as
shown in the table at right (factory-preset to 330
ohms). To change, set the rotary switch to the
desired impedance using a screwdriver blade.
[Note]
When using the 100 line, never set the impedance to
170 ohms. The speaker itself or the power amplifier
may be damaged.
7. REAR COVER USAGE
F Series speakers feature a rear cover that cleanly
conceals the speaker terminals on the rear panel.
To remove the cover, insert a finger in the line feed
slot and pull the cover away from the speaker. To
reattach, simply snap the cover back into place.
If required, the positioning of the cover's line feed
slot can be easily reversed by snapping the cover on
"upside down".
Model F-160WP must be mounted with the line feed
slot facing down.
