Frequently Asked Questions - ALTI4M Audac
How do I connect the ALTI4M speaker to an amplifier?
Use the screw terminals on the back of the speaker. Connect the amplifier output wires to the corresponding + and - terminals, ensuring proper polarity. Recommended amplifier power: 30-60 W RMS per channel at 8 ohms.
Can the ALTI4M be used outdoors?
The ALTI4M has an IP33 rating, which means it is protected against rain and splashing water, but not against immersion. It is suitable for covered outdoor areas like patios or verandas.
What is the recommended mounting height for the ALTI4M?
For optimal sound dispersion, mount the speaker at ear height when seated (approximately 1.5 to 2 meters from the floor). Adjust the tilt to direct sound towards the listening area.
How do I clean the ALTI4M speaker?
Use a soft, dry cloth to wipe the speaker cabinet. For stubborn dirt, slightly dampen the cloth with water. Do not use solvents or abrasive cleaners, as they may damage the finish. Clean the grille with a vacuum cleaner on low setting.
What is the difference between the ALTI4M and ALTI6M?
The ALTI4M features a 4-inch woofer, while the ALTI6M has a 6-inch woofer. The ALTI4M is smaller and lighter, suitable for smaller rooms or as surround speakers, whereas the ALTI6M provides higher output and deeper bass for larger spaces.
Can I paint the ALTI4M to match my interior?
Yes, the speaker cabinet and grille can be painted. Use a water-based acrylic paint. Remove the grille and mask the drivers before painting. Lightly sand the surface for better adhesion.
What type of cable should I use for installation?
Use stranded speaker wire of 14-16 AWG (2.5-1.5 mm²) for distances up to 50 meters. For longer runs, use thicker wire to minimize resistance. Keep cables away from power lines to avoid interference.
Is the ALTI4M compatible with 70V/100V distributed audio systems?
The standard ALTI4M is an 8-ohm speaker for low-impedance systems. For high-impedance systems, use the ALTI4M-HI model (if available) or add an external line transformer (e.g., 70V/100V) rated for at least 30W.
How do I adjust the tilt of the ALTI4M after mounting?
The bracket allows both horizontal and vertical tilt. To adjust, loosen the mounting screws slightly, position the speaker, then retighten. Avoid overtightening to prevent damage to the bracket.
Does the ALTI4M come with a warranty?
Yes, the ALTI4M comes with a 5-year warranty from Audac against manufacturing defects. This covers parts and labor. Register your product on the Audac website to activate the warranty.
