Frequently Asked Questions - CS 120P Extron
How do I set the tap on the 70V transformer?
On the CS 120P, the 70V taps are selected with the rotary switch on the back can. Choose 5W, 10W, 20W, or 40W, or 8-ohm direct mode.
What are the recommended mounting requirements?
The speaker mounts into a ceiling tile using the included C-ring and tile bridge. Ensure the ceiling and tile can support at least 15 kg to prevent vibration.
Can I paint the grille?
Yes, the grille is paintable. Remove the grille, clean it, apply a thin coat of latex paint, and let it dry completely before reinstalling.
What is the maximum power I can feed to the CS 120P?
It handles 120 W continuous and 240 W peak in 8-ohm mode. In 70V mode, the maximum tap is 40W. Do not exceed these ratings to avoid damage.
How do I connect multiple speakers?
In 70V mode, daisy-chain through the spring terminals. Ensure total wattage on the line does not exceed the amplifier's rating. In 8-ohm mode, parallel speakers with a resulting nominal impedance not below 4 ohms.
Why is there no sound from the speaker?
Check the volume switch and wiring. Verify the transformer tap is correct. Test the driver by connecting a 1.5V battery to the terminals – a click indicates it is working.
How do I clean the CS 120P?
Use a dry microfiber cloth to wipe the grille and housing. Avoid water, solvents, or abrasive cleaners as they may damage the finish.

The CS 120P reproduces frequencies from 55 Hz to 20 kHz, suitable for both background and foreground AV systems.
Does the speaker come with a warranty?
Extron provides a 5-year warranty on parts and labor. Keep your purchase receipt for warranty service.
Can I replace the drivers if they fail?
