Setup and Installation
The Herdio HCS818 speakers are designed for easy flush mounting in walls or ceilings. Follow these steps for proper installation and wiring.
Speaker Installation
- Choose Location: Select a suitable location in your wall or ceiling, ensuring there are no obstructions (e.g., electrical wires, pipes) behind the surface.
- Mark Cutout: Use the provided cutout template to mark the exact cutting area on your wall or ceiling.
- Cut Opening: Carefully cut the marked opening using an appropriate tool (e.g., drywall saw). The cutout diameter is 8.07 inches (20.5 cm).
- Remove Speaker Grill: Gently pry off the speaker grill using a small flat-head screwdriver or a similar tool.
- Insert Speaker: Insert the speaker into the cutout opening.
- Secure Speaker: Tighten the speaker clips with screws. These clips will pivot outwards and clamp onto the wall/ceiling material, securing the speaker in place.
- Replace Grill: Once the speaker is securely mounted and wired, carefully place the speaker grill back onto the speaker.
Speaker Wiring
The HCS818 speakers are passive and require an external amplifier for operation. Ensure your amplifier is compatible with 8-ohm speakers.
- Prepare Wires: Use the provided speaker cables. Identify the positive (red) and negative (black) wires. Strip a small amount of insulation from the ends of each wire.
- Connect to Speakers: Connect the red (+) wire to the red terminal on the speaker and the black (-) wire to the black terminal. The speakers feature depressible terminals for easy connection.
- Connect to Amplifier: Connect the other end of the speaker cables to the corresponding positive and negative speaker output terminals on your external amplifier. Ensure correct polarity for all connections.
- Power Supply: Plug your amplifier into a power supply.
Note: These speakers are passive and require an external amplifier to function. This model does not include an integrated amplifier.
