What is the difference between the ACS-40T and the ACS-40TS?
The ACS-40TS features a transformer tap selector switch on the rear of the loudspeaker, allowing quick adjustment for 70V/100V distributed audio systems. The standard ACS-40T requires manual wire changes on the transformer terminal.
Can the ACS-40TS be used outdoors?
No, the ACS-40TS is rated IP30, which makes it suitable only for indoor installations. For outdoor use, consider a weatherproof loudspeaker from the Martin Audio Adorn range.
How do I select the correct transformer tap on the ACS-40TS?
Turn the tap switch on the rear of the speaker to match your amplifier output voltage (70V or 100V) and desired wattage. For example, if your system is 70V and you need 10W, set the switch to the 10W tap.
What is the recommended ceiling cutout size?
The required ceiling cutout for the ACS-40TS is 180 mm in diameter. Ensure the ceiling thickness is between 5 mm and 25 mm for proper clamp engagement.
Is the grille paint-friendly?
Yes, the grille is made of perforated steel with a white finish. You can repaint it to match your decor. Use a light aerosol spray paint and avoid blocking the perforations.

Martin Audio provides a 5-year limited warranty against defective materials and workmanship. Register your product online to activate coverage.
How do I connect the ACS-40TS to a 70V amplifier?
Connect the amplifier output to the speaker's barrier block. Set the tap switch to the 70V section and choose the desired power. For 8-ohm operation, set the switch to Bypass and connect directly to the 8-ohm positions.
What should I do if there is no sound from the speaker?
Check the tap switch position, verify all wiring connections are secure, and test with a multimeter for continuity. Also ensure the amplifier channel is not muted and the source level is turned up.
Does the ACS-40TS include a back box?

Can I use the ACS-40TS as a stereo speaker?
Absolutely, the ACS-40TS works well as a left or right channel in a hi-fi or background music system. Use the Bypass mode and connect directly to a stereo amplifier rated for 8-ohm loads.
