4. Setup and Installation
4.1. Speaker Overview
The OSD Audio C1070V features an 8-inch woofer and a 70V transformer for commercial audio systems. It includes a white metal grille for a discreet appearance.
4.2. Mounting
The C1070V speaker is designed for in-ceiling installation. It has a product dimension of 3.15"D x 12"W x 12"H.
For typical assembly, follow these steps:
- Cut a round loudspeaker clearance hole of 11.5" (292mm) in the ceiling tile.
- If using a back box (sold separately), ensure it is compatible with the C1070V.
- Mounting holes are 11.25" (286mm) center to center, with 4 tapped holes.
- Insert the speaker into the cutout, ensuring it is securely fastened. For suspended ceilings, consider using metal frames (e.g., Bogen TB-8) for additional support, as the speaker may be too heavy for ceiling tiles alone.
4.3. Wiring (70V Connection)
The OSD Audio C1070V is designed for 70V constant voltage audio systems, allowing multiple speakers to be daisy-chained to a 70V powered amplifier. The speaker includes wattage taps via a front dial and rear indicator for easy setup.

Connect the appropriate wires from your 70V amplifier to the speaker's terminals based on your desired wattage setting. Ensure all connections are secure to prevent signal loss or damage.
5. Operating Instructions
Once installed and wired, the speaker will operate as part of your 70V audio system.

If you experience issues with your speaker, consider the following:
- No Sound: Check all wiring connections from the amplifier to the speaker. Ensure the amplifier is powered on and functioning correctly. Verify the correct wattage tap is selected.
- Distorted Sound: Ensure the amplifier's output level is not too high, causing clipping. Check speaker wiring for shorts or loose connections.
