4.1 Tools Required
- Drill with appropriate hole saw (4-inch diameter recommended for speaker cutout)
- Wire strippers
- Screwdriver (if needed for junction box access)
- Voltage meter (for verifying 70V line)
4.2 Installation Steps
- Power Disconnection: Before beginning any work, ensure that the power to the circuit where the speaker will be installed is completely disconnected at the main breaker.
- Location Selection: Choose a suitable location in the ceiling, ensuring there are no obstructions (e.g., joists, pipes, electrical conduits) behind the mounting area.
- Cutout Creation: Using a 4-inch hole saw, carefully cut a circular opening in the ceiling at the chosen location.
- Wiring:
- Run the 70V audio cable from your amplifier to the speaker cutout.
- The C160W features solder lug inputs. Strip approximately 1/4 inch of insulation from the ends of the audio cable.
- Carefully solder the positive (+) wire from the 70V line to the positive (+) solder lug on the speaker, and the negative (-) wire to the negative (-) solder lug. Ensure secure connections.
- The speaker has a built-in 70V transformer with various taps. Select the appropriate wattage tap (e.g., 5W, 10W) based on your system's design and desired output level. Connect the 70V line to the selected tap.
- Speaker Insertion: Gently push the speaker into the cutout. The spring-loaded mounting clips will automatically pivot outwards and secure the speaker firmly against the ceiling surface.
- Final Check: Once installed, ensure the speaker is flush with the ceiling and securely held.
- Power Reconnection: Reconnect power to the circuit and test the speaker.

4.3 Painting the Speaker
The C160W features a paintable white finish. If you wish to match the speaker to your ceiling color, use a high-quality, non-abrasive paint. It is recommended to remove the grille before painting to ensure even coverage and prevent paint from clogging the speaker cone.
5. Operating Instructions
The Yorkville C160W speaker operates as part of a 70V constant voltage audio distribution system. Once properly installed and connected to a compatible 70V amplifier, it will reproduce audio signals from the amplifier.
- Power On: Ensure your 70V amplifier is powered on and configured correctly.
- Audio Source: Play audio from your connected source (e.g., music player, microphone for paging).
- Volume Control: Adjust the volume level using your 70V amplifier's controls. Individual speaker volume cannot be adjusted directly on the C160W.
- System Design: The overall sound level and coverage will depend on the number of speakers, their placement, and the total wattage output of your 70V amplifier.
6. Maintenance
The Yorkville C160W speaker requires minimal maintenance.
- Cleaning: To clean the speaker grille and housing, gently wipe with a dry, soft cloth. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the finish or internal components.
- Inspection: Periodically inspect the speaker for any signs of damage or loose connections. If any issues are found, disconnect power and consult a qualified technician.
