5. Setup and Installation
5.1 Mounting the Speakers
The VOYZ speakers are designed for wall mounting and come with integrated mounting brackets. Ensure the mounting surface is sturdy enough to support the weight of the speakers.
- Determine the optimal location for your speakers, considering sound dispersion and cable routing.
- Position the speaker against the wall and mark the drilling points for the mounting bracket.
- Drill pilot holes at the marked locations. Use appropriate wall anchors if mounting into drywall.
- Secure the speaker's mounting bracket to the wall using suitable screws.
- Adjust the speaker angle as desired using the swivel knob on the bracket.

5.2 Wiring and Connections
Connect the speakers to your audio amplifier using appropriate speaker wire. Observe correct polarity (positive to positive, negative to negative) to ensure optimal sound performance.
- Locate the red (+) and black (-) binding posts on the rear of each speaker.
- Connect the positive (+) terminal of your amplifier's speaker output to the red (+) terminal on the speaker.
- Connect the negative (-) terminal of your amplifier's speaker output to the black (-) terminal on the speaker.
- Ensure all connections are secure to prevent signal loss or short circuits.

5.3 Impedance/Power Selection Switch
The VZ-B105T speakers feature a selector switch on the rear panel, allowing you to choose between different power taps for 70V/100V constant voltage systems or standard 8 Ohm operation. Ensure the switch is set to the correct position matching your amplifier's output and system requirements.
- 8 Ohm: For standard home audio amplifiers.
- 70V/100V Taps: For commercial constant voltage systems. Select the wattage tap (e.g., 5W, 10W, 15W) that corresponds to your system's design.
Caution: Setting the switch incorrectly can damage the speaker or amplifier. Consult a professional if unsure about your system's requirements.
6. Operation
Once properly installed and connected, your VOYZ speakers are ready for use. Ensure your amplifier is turned off before making connections, then power it on and adjust the volume to a comfortable listening level. These speakers are designed to deliver clear and dynamic audio for a variety of applications.
For optimal sound quality, ensure the audio source is of good quality and the amplifier is not overdriven, which can lead to distortion and potential speaker damage.
7. Maintenance
To ensure the longevity and performance of your VOYZ speakers, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe down the speaker cabinets. For stubborn dirt, a slightly damp cloth can be used, but avoid excessive moisture. Do not use harsh chemicals or abrasive cleaners.
- Outdoor Use: While water-resistant, avoid direct exposure to high-pressure water jets or prolonged submersion. If used in harsh outdoor conditions, periodically check connections for corrosion.
- Inspection: Periodically inspect speaker wires and connections for any signs of wear or damage.
8. Troubleshooting
If you encounter issues with your speakers, refer to the table below for common problems and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound | Loose connections, incorrect amplifier settings, incorrect impedance switch setting. | Check all speaker wire connections. Ensure amplifier is on and input is selected. Verify the impedance/power selector switch is set correctly. |
| Distorted Sound | Overdriven amplifier, damaged speaker wire, incorrect impedance setting. | Reduce amplifier volume. Check speaker wire for damage. Confirm impedance/power selector switch setting. |
| One Speaker Not Working | Faulty connection to one speaker, damaged speaker wire, amplifier channel issue. | Check connections for the non-working speaker. Swap speakers to determine if the issue is with the speaker or the amplifier channel. |
