Frequently Asked Questions - FF 120T Extron

How do I connect the FF 120T to an amplifier?

Connect the amplifier output to the speaker input using a Speakon cable or bare wires to the barrier strip. Ensure the amplifier is off during connection. Match impedance (8 ohms) and do not daisy-chain more than 2 speakers per channel.

What is the recommended placement for optimal sound?

Place the speaker at ear level, away from walls or corners to avoid bass boom. For stereo, form an equilateral triangle with the listening position. Ensure the speaker is securely mounted.

Can I use the FF 120T outdoors?

The FF 120T is designed for indoor use only. Exposure to moisture or extreme temperatures may damage the speaker. If outdoor use is required, provide weather protection.

How do I clean the speaker grille?

Use a soft, dry cloth to dust the grille. For stubborn dirt, lightly dampen the cloth with water and mild soap, then wipe gently. Do not use solvents or abrasive cleaners. Ensure no liquid enters the driver.

What is the power handling of the FF 120T?

The RMS power handling is 120 watts, with a peak of 240 watts. For best performance, use an amplifier that delivers 100-150 watts RMS per channel at 8 ohms.

Can I mount the speaker on a wall?

Yes, the FF 120T includes a surface-mount bracket that allows wall or ceiling mounting. Follow the instructions to secure the bracket to a solid structure, then attach the speaker.

What should I do if the speaker produces distorted sound?

Check the amplifier settings: ensure it is not clipping. Verify connections are secure. Test with a different audio source. If distortion persists, inspect the speaker for damage. Reduce volume to avoid further harm.

Is the FF 120T compatible with low-impedance (70V/100V) systems?

No, the FF 120T is a low-impedance 8-ohm speaker. It is not designed for constant-voltage (70V/100V) systems. Use with a standard amplifier.

How do I place the speaker in a multi-room setup?

Connect each speaker in parallel, ensuring total impedance does not drop below the amplifier's minimum rating (e.g., two 8-ohm speakers in parallel = 4 ohms). Use a speaker selector switch if needed.

What is the warranty period for the FF 120T?

Extron warrants the FF 120T for three years from the date of purchase against defects in materials and workmanship. Contact Extron support for warranty claims.

USER MANUAL FF 120T Extron

This setup guide contains installation information about the Extron FF 120T Flat Field® speaker. This speaker is designed for use in plenum rated ceiling spaces and can be dropped into a standard 2 feet by 2 feet or 2 feet by 4 feet (with supplied cross bars) false ceiling tile space on a T-bar grid.

WARNING: May result in serious injury. Installation and service must be performed by authorized personnel only.

Factors to Consider Before Installation

• All wiring and electrical connections must conform to all applicable building codes and local ordinances.
• Installation in a plenum-rated environment requires plenum rated cable or conduit.

Wire Gauge Table

	Number of Wires per Connection Point	Maximum Wire Gauge
8Ω Configuration	1	12 AWG
	2	14 AWG
70 V/100 V Configuration	1	14 AWG
	2	16 AWG

- If using secondary support cables, the installer provides the cables.

Installation

1. Disconnect power — Power down all attached devices before proceeding.
2. Remove and cut ceiling tile — Remove the ceiling tile where the FF 120T will be installed. Cut out a 12-inch section from either end of the tile where the speaker will be installed, as shown below.

24" x 48" Ceiling Tile 24" x 24" Ceiling Tile

1. Install the T-rail — Install the T-rail crosspiece into the ceiling opening up against the cut tile.

1. Transformer cover plate — Loosen, but do not remove, the two screws on the top of the transformer cover plate, as shown at right. Next, slide and remove the transformer cover plate, which is installed with the transformer side down.

2. Using Flexible Conduit — When using flexible conduit, insert the conduit into the cover plate opening using an appropriate conduit adapter, and secure the conduit to the plate as shown below.

1. Distributed audio system (70 V or 100 V) or direct connection —

2. if wiring a 100 V or 70 V distributed system and using the transformer, proceed to step 7.

3. if bypassing the transformer and wiring directly from the amplifier, proceed to step 9.

4. Connect cables from the amplifier to the transformer on the FF 120T transformer cover plate.

a. Pull the wires from the amplifier through and out of the conduit, if a conduit is used.
b. Route the two wires from the amplifier through the cover plate hole to the transformer side. See the wire gauge table on page 1.
c. Strip 3/16" (5 mm) from the wire ends and keep the wire end strands together by twisting them. Do not tin the wires.

d. Secure the wires to the appropriate taps on the captive screw connectors of the 7-connector terminal block (on the transformer side of the cover plate) as indicated on the tap label (see the note below). The black negative (-) wire attaches to the "COM" terminal, and the red positive (+) wire attaches to the desired terminal tap (see the diagram at right).

NOTE: Observe the 70 V or 100 V system designation as indicated on the tap label.

e. Use a small flat blade screwdriver to tighten the terminal block screws.
f. To wire additional speakers, route speaker wires from the second speaker through the cover plate hole to the transformer side. Twist the black negative (-) wires together and the red positive (+) wires together before inserting them into the terminal block. Additional speakers can be daisy-chained this way, as shown at right.

1. Connect wires from the transformer to the speaker.

a. Keep the wire strands together by twisting them (do not tin the wires).
b. Connect the red positive (+) wire to the + speaker terminal and connect the black negative (-) wire to the - speaker terminal as shown in step 9b below.
c. Proceed to step 10.

1. See the following block diagram.

a. Route the wires from the amplifier to the speaker using the same procedure for routing speaker wire (and conduit if applicable) through the transformer cover plate as described in steps 4 through 7b (see the wire gauge table on page 1). Strip 3/16 inch (5 mm) from the ends of the two speaker wire leads (+ and -) coming from the amplifier. Keep the wire strands together by twisting them (do not tin the wires), and secure the wires to the input terminals of the speaker while observing the correct polarity.

b. Connect the red positive (+) wire to the + speaker terminal and connect the black negative (-) wire to the - speaker terminal, depending on whether one or two speakers are being connected, as shown below.

One Speaker

Two Speakers

1. Replace the transformer cover plate and tighten the two cover plate screws that were loosened in step 4.

2. Set the speaker on top of a T-rail making sure to hide the edges behind the grid rail.

1. If secondary support cables are being used, install them (see the illustration below).

ATTENTION: DO NOT allow any slack in these support cables.

NOTE: Observe all applicable building codes and local ordinances when installing the speaker.

ATTENTION: Repeated bending of the tab may cause it to break off.

a. Temporarily remove a ceiling tile adjacent to the speaker and set it aside.
b. Connect a secondary support cable through the secondary attachment point, and attach it to one of the bendout tabs located on either side of the speaker.
c. Attach the other end of the cable to a sturdy part of the building (studs, roof struts, and so on).
d. For additional secondary support cables repeat as needed (see the FF 120T User Guide for further details).
e. Replace the ceiling tile removed in step 12a.

1. Check all wiring before powering up the amplifier.
