Thank you for purchasing the Factor Electronics C-660TB high performance in-ceiling speakers.
Please read this entire manual to get the most from your C-660TB speakers and ensure proper
Installation. The C-660TB is designed to provide high quality background music and paging in a
variety of Installations like schools, houses of worship, retail, industrial, office buildings and homes.
The C-660TB can be used with high impedance 25/70 volt amplifiers or low impedance 4/8 ohm
amplifiers safely. To insure proper installation please set the wattage tap dial and the wire-in
terminals to the correct settings described in this manual.
The C-660TB includes:
1. Speaker with metal back box
2. Removable grille
3. T-Bar ceiling support
4. Cutout template
Installation T-Bar Ceiling:
1. Use the cutout template to trace a circle in the ceiling tile.
2. Use a sharp blade or saw to cut the hole.
3. Place the T-Bar ceiling support on the back side of the ceiling tile.
4 Place the C-660TB through the cutout.
5. Using a screwdriver or drill fitted with a Phillips bit to tighten the four L-Clamp screws until
the L-Clamps are snug to the back of the T-Bar ceiling support. Do not over tighten!

6.The C-660TB provides an easy way for installers to set and adjust wattage taps with a front baffle
screw terminal. The taps can be adjusted after the speaker is installed in the ceiling. We recommend
Setting the correct taps prior to installation then adjusting the taps after installation only when necessary.
Always set the taps to the 25 volt settings when using a 25 volt amplifier and the 70 volt settings when
using a 70 volt amplifier. Never exceed the wattage rating of the connected amplifier.
Combine the wattage settings of all the speakers in the system to calculate the total wattage.
Example: 10 speakers all tapped at 15 watts = 150 watts. Use an amplifier that provides a minimum
of 150 watts at 25 or 70 volts.
16 ohm Bypass:
This setting bypasses the internal transformer. Never use this setting when connecting the C-660TB to
a constant voltage 25/70 volt amplifier, this will overload the amplifier and possibly void the warranty.
Use the 16 ohm setting when connecting the C-660TB to a low impedance mono or stereo amplifier
with a minimum impedance rating of 4-16 ohms. If you are unsure of how to connect the C-660TB,
please call of e-mail Factor Electronics for technical support.
7. The C-660TB provides a 4 position terminal block connector to connect the speaker(s) to the amplifier.
The terminal block connector provides two + POSITIVE terminals and two – NEGATIVE terminals which
Can be used for input to the speaker and output to another speaker which saves installation time.
Parallel, series or combinations of series/parallel wiring can easily be achieved.
