Installation Instructions

General Suggestions

• Installation Position: Speakers are recommended to be mounted at a height of 1.8-2 meters from the ground.
• Speaker Spacing: The optimal interval between speakers is within 5 meters for best performance.

U-Shape Bracket Installation

This bracket allows for vertical installation. The diagram shows the speaker attached to a wall using screws. The rotation angle is approximately ±90°.

Space between Bracket Installation Holes:

• NVS 10500020WS/NVS 10510020WS: 147 mm
• NVS 10520030WS/NVS 10530030WS: 147 mm
• NVS 10540040WS/NVS 10550040WS: 177 mm

Horizontal Installation: The bracket supports both vertical and horizontal mounting. For installation, select an appropriate location on the wall and install two 4mm diameter nails or screws, ensuring a clearance of 4-6mm between the nail cap and the wall. Connect the speaker with the audio cable. Hang the speaker on the bracket, adjust the angle, and tighten the knobs to ensure a secure installation.

Multi-angle Adjustable Bracket Installation

(Only supports NVS 10520030WS/NVS 10530030WS)

The installation involves two parts:

1. Unscrew the bracket knob, separate Part 1 and Part 2.
2. Fix the speaker and Part 1 to the wall. Select the appropriate position for Part 2 on the wall and fix it. (Refer to Fig. 1).
3. Connect the speaker with the audio cable.
4. Attach Part 1 of the speaker onto the sphere of Part 2. Adjust the speaker angle and secure Part 1 and Part 2 with the knob screw. (Refer to Fig. 2).

The multi-angle bracket allows for adjustable angles, with upper angle adjustment up to 10° and lower angle adjustment up to 17°. The overall rotation angle is approximately ±51°.

Rear Panel Details & Power Settings

Power Adjustment Knob

The rear panel features a power adjustable knob and an audio line interface. The knob allows selection of power output and input modes (70V, 100V, or 8Ω constant resistance).

Terminal Settings for NVS-10520020WS/NVS-10530020WS:

Note: When using constant voltage mode, do not set the knob to the 8Ω setting. Adjusting to the "-" position under 100V can cause speaker damage.

Terminal Settings for NVS 10520030WS/NVS 10530030WS:

Note: When using constant voltage mode, do not set the knob to the 8Ω setting. Adjusting to the "-" position under 100V can cause speaker damage.

Terminal Settings for NVS 10540040WS/NVS 1050040WS:

Note: When using constant voltage mode, do not set the knob to the 8Ω setting. Adjusting to the "-" position under 100V can cause speaker damage.
