Safety Information
- Electrical Safety: Always ensure that all power to audio equipment is turned off before making any connections. Incorrect wiring can cause damage to your equipment or pose an electrical hazard.

Setup
This section guides you through the installation of the in-ceiling speakers and the connection of the speaker selector.
1. Speaker Installation
- Choose Location: Select appropriate locations in your ceiling for each of the eight speakers. Ensure there are no obstructions (e.g., electrical wires, plumbing, studs) behind the chosen spots.
- Cut-out: Using a template (often included with speakers or available from manufacturer), carefully mark and cut a circular opening in the ceiling. The recommended cut-out dimension is 6 1/2 inches (16.5 cm) in diameter with a depth of 2 5/8 inches (6.7 cm).
- Wiring: Run speaker wires from the location of your speaker selector to each speaker opening. Ensure sufficient length for connections. Strip approximately 1/2 inch (1.2 cm) of insulation from the ends of the speaker wires.
- Connect Speakers: Connect the positive (+) terminal of the speaker wire to the red terminal on the speaker, and the negative (-) terminal of the speaker wire to the black terminal on the speaker.
- Mount Speakers: Insert the speaker into the cut-out. Most in-ceiling speakers use a dog-leg mounting system. Tighten the mounting screws evenly until the speaker is securely fastened to the ceiling. Do not overtighten.
2. Speaker Selector Connection
The speaker selector allows you to connect up to four pairs of speakers to a single stereo amplifier/receiver and control their volume independently.

This image displays the main components of the Pyle KTHSP85p system: the central speaker selector unit and two of the eight in-ceiling speakers. The speaker selector features individual volume controls for each zone.
- Connect Speakers to Selector: Connect the speaker wires from each pair of in-ceiling speakers to the corresponding 'Speaker Output' terminals (Zone 1, Zone 2, Zone 3, Zone 4) on the rear of the speaker selector. Ensure correct polarity (+ to + and - to -). Each zone will accommodate two speakers (one left, one right).
- Connect Amplifier to Selector: Connect the speaker output terminals of your stereo amplifier or receiver to the 'Amplifier Input' terminals on the rear of the speaker selector. Again, observe correct polarity.
- Power On: Once all connections are secure, you may power on your amplifier/receiver and the speaker system.
Operating
The Pyle KTHSP85p system is designed for straightforward operation.
- Zone Selection: The speaker selector unit features individual buttons or switches for each of the four zones. Pressing a button will engage or disengage the speakers in that specific zone.
- Volume Control: Each zone on the speaker selector has an independent rotary volume control knob. Turn the knob clockwise to increase the volume for that zone and counter-clockwise to decrease it.
- Master Volume: The overall system volume is controlled by your connected amplifier or receiver. Use the individual zone volume controls for fine-tuning the sound level in each room.
Maintenance
Proper care will ensure the longevity and performance of your speaker system.
- Cleaning: Dust the speaker grilles and the speaker selector unit regularly with a soft, dry cloth. For stubborn marks, a slightly damp cloth can be used, but ensure no moisture enters the unit.
- Avoid Liquids: Do not spray cleaning liquids directly onto the speakers or selector.
- Environmental Conditions: Keep the system away from extreme temperatures, direct sunlight, and high humidity.
Troubleshooting
If you encounter issues with your Pyle KTHSP85p system, refer to the following common problems and solutions:
- No Sound from a Zone:
- Ensure the specific zone button on the speaker selector is engaged.
- Check the volume knob for that zone; it may be turned down completely.
- Verify all speaker wire connections for that zone at both the speaker and the selector.
- Confirm the amplifier/receiver is powered on and playing audio.
- No Sound from Any Zone:
- Check the connections between your amplifier/receiver and the speaker selector.
- Ensure your amplifier/receiver is powered on and its volume is not muted or set too low.
- Verify the audio source connected to your amplifier/receiver is functioning correctly.
- Distorted Sound:
- Reduce the volume on both the speaker selector and your amplifier/receiver.
- Check for loose or shorted speaker wire connections.
- Ensure the impedance of your speakers (8 Ohms) is compatible with your amplifier and the speaker selector (handles 100 Watts per channel with minimum 8 Ohms).
