Frequently Asked Questions - QSA 112.0 FBT
How do I connect the QSA 112.0 to an amplifier?
Use the NL4 SpeakON connectors on the back panel. Connect the amplifier output to the input connector, and if linking, use the second connector to loop to another speaker. Ensure the amplifier is off before making connections.
What amplifier power is recommended for the QSA 112.0?
A recommended amplifier power of 300 to 600 W RMS per channel at 8 ohms is ideal. This provides enough headroom without risking damage to the drivers.
Can I use the QSA 112.0 outdoors?
The speaker is not weatherproof. Avoid exposure to rain, moisture, or extreme temperatures. If used outdoors, provide adequate shelter and protection from the elements.
How should I position the speakers for best sound?
Place the speakers at ear level or slightly above, angle towards the listening area. Avoid corners and walls to reduce bass buildup. For stereo, position them equidistant from the listening position.
How do I clean and maintain the speaker?
Use a soft dry cloth to wipe the cabinet and grille. Do not use water or cleaning agents, as they may damage the finish or components. Check and tighten any screws if needed.
Can I mount the QSA 112.0 on a wall or ceiling?
Yes, it has rigging points for flown installation. Use appropriate mounting brackets and safety ropes. For pole mounting, insert the speaker onto a sturdy speaker stand rated for its weight.
What is the impedance of the QSA 112.0?
The nominal impedance is 8 ohms. When connecting multiple speakers, ensure the total load is compatible with your amplifier's specifications.
Does the speaker come with a built-in crossover?
Yes, it has a passive crossover network that splits the audio signal between the woofer and tweeter. This allows you to use a single amplifier channel per speaker.
Can I replace the drivers if they are damaged?
Yes, the woofer and tweeter are replaceable. Contact FBT or an authorized dealer for genuine replacement parts. Disconnect power and remove the grille and mounting screws to access the drivers.
How do I ensure the speaker is safely installed?
Always use rated rigging hardware and follow the included safety guidelines. Check all mounting points for tightness and secure accent-proof cables. For overhead installation, use a secondary safety chain or wire.
