Frequently Asked Questions - WA40 NUVO

How do I connect the WA40 to my TV?

Use an optical or coaxial digital audio cable from your TV's audio output to the corresponding input on the WA40. Alternatively, you can use analog RCA cables if your TV has them.

Can I control the WA40 with my smartphone?

Yes, download the NUVO app from the App Store or Google Play. Connect the receiver to your home network via Ethernet or Wi-Fi (if supported), then use the app to select sources and adjust volume per zone.

How many speakers can I connect?

The WA40 supports up to 4 zones, each with a pair of speakers (8 ohms recommended). You can connect 2 speakers per zone for a total of 8 speakers.

What should I do if there is no sound?

Check that the receiver is powered on and the correct input source is selected. Ensure speaker wires are securely connected and not shorted. Verify volume is not muted and is turned up. Try a different source or cable.

Can I use the WA40 outdoors?

The WA40 is designed for indoor use only. Do not expose it to rain, moisture, or extreme temperatures. For outdoor speakers, use weatherproof models and keep the receiver in a dry location.

How do I reset the WA40 to factory settings?

With the unit on, press and hold the 'Menu' button for 5 seconds until 'Factory Reset' appears on the display. Confirm with the 'Enter' button. The receiver will restart with default settings.

What is the Bluetooth range?

The Bluetooth range is approximately 30 feet (10 meters) in open space. Walls or obstacles may reduce the range.

Can I use different music sources in different zones?

Yes, the WA40 supports independent source selection for each zone. You can play Bluetooth in zone 1, radio in zone 2, etc.

How do I update the firmware?

Check the NUVO website for firmware updates. Download the file to a USB drive, insert it into the USB port on the WA40, then navigate to 'Settings > Firmware Update' via the front panel or app.

The remote control is not working. What can I do?

Replace the batteries in the remote. Make sure there are no obstructions between the remote and the receiver's IR sensor. Check that the receiver's IR input is not blocked. If the issue persists, try resetting the remote by removing batteries for 30 seconds.

NV-WA40W

Installation and User Guide

Introduction

The NV-WA40W-AMP is a versatile 40-watt in wall zone amplifier perfectly suited to a variety of tasks. Its design allows two line level sources to be permanently wired into the back panel as a switchable input A or B, and two optional front panel stereo mini inputs allows any local source to be easily amplified to dedicated speakers.

The WA40W-AMP fits in educational classroom settings, doctors' offices, hotels, and many other installations where a compact, inexpensive amplifier solution is needed.

NV-WA40W-AMP Front Panel features

1. Volume: These buttons increase and decrease the signal output of the amplifier.
2. A/B: This button toggles between the A and B hardwired inputs on the back panel or the individual front panel inputs. Use of the front panel inputs will override those on the back panel.
3. IR Sensor: The WA40W-AMP is capable of receiving IR (Infrared) light signals from the NuVo wireless remote control. This enables the power, volume and A/B source selection to be done wirelessly.
4. Audio Inputs: Two stereo inputs are available for front panel use with any device that provides a stereo line level signal.
5. Power: This button turns the amplifier on and off as a toggle function.

NV-WA40W-AMP Back Panel Features

1. DC Input: This 16V DC, 2.81A input connects to the included power supply. Once connected, the power supply can plug into any AC power source.
2. Speaker Output: The speaker output section terminates with standard audio wire. This provides the amplified audio signal to the attached speakers. The NV-WA40W-AMP is designed for a pair of 4-ohm speakers or a single stereo speaker rated at 4-ohms per channel.
3. Audio Inputs A and B: These inputs allow up to two line level sources to be permanently hardwired into the back panel. Selection for source playback is made through from the front panel A/B button or the wireless remote control. The inputs are automatically overridden when one of the front panel audio inputs is used.

NV-WA40W-RC Remote Control (sold separately)

1. Volume: These buttons increase and decrease the signal output of the amplifier.
2. A/B: This button toggles between the A and B hardwired inputs on the back panel or the individual front panel inputs. Use of the front panel inputs will override those on the back panel.
3. Power: This button turns the amplifier on and off as a toggle function.

Installing the NV-WA40W-AMP

Step 1: Choose the desired location of the WA40W-AMP. It is designed to fit into a standard 35mm deep UK back box. The WA40W-AMP dimensions are a standard 50 x 50mm UK size, and has a screwless trim plate kit included in the package. Make the appropriate cutout for the mounting back box. The amplifier itself is compatible with standard 50 x 50mm wall plates. Note that a standard size Decora®* trim plate is available in regions where the standard Decora mounting box is installed, such as North America.

Step 2: Define the best location for the speakers that will be connected to the WA40W-AMP amplifier. These can be in wall, in ceiling, floor standing, or bookshelf speakers, but should not present less than an 4-ohm load to the amplifier. 16-gauge speaker wire, either two or four conductor, is recommended for this purpose. The wire should be routed to the cutout for the WA40W-AMP for termination into the back of the component, as shown in fig. 1.

Fig. 1

* Decora is a registered trade mark of the Leviton Corporation.

Step 3: Along with the speaker wire, route the power supply to the same cutout and terminate the positive and negative leads at the back of the WA40W-AMP, as shown in fig. 2.

Fig. 2

Step 4: Connect the optional back panel audio inputs. There are two hardwired audio inputs on the back of the WA40W-AMP. They are labeled Input A and Input B. Two individual audio sources can be wired to these inputs simultaneously. The actual source for playback is selected from the front Panel A/B button, or from the A/B button on the wireless remote control.

To make the termination, strip the left, right and ground leads on the input side of a stereo RCA or stereo mini, 3.5mm audio cable. Terminate those leads into the appropriate screw down terminals on the WA40W-AMP.

Step 5: When the desired inputs on the WA40W-AMP are complete, screw the mounting plate into the installed back box.

Step 6: Snap the WA40W-AMP into the installed mounting plate and install the screwless trim plate over the entire assembly.

The WA40W-AMP is now ready for operation. When it is turned on, the ON LED will light. Any incoming signal wired to the back panel will be amplified to the attached speakers. When an audio source is plugged into one of the front panel 3.5mm inputs, it will automatically override the back panel inputs.

The WA40W-SPK Speakers

The NV-WA40W package includes a pair of 0n-wall speakers. These are easily mounted to any wall using the included brackets, as shown in fig. 3.

To properly terminate the speaker, strip about 5 to 6mm of insulation, exposing the inner copper wire. Press the desired speaker terminal and insert the stripped portion of the speaker wire, as shown in fig. 4. Be careful to terminate the positive and negative conductors the same at the speakers as you did at the WA40W-AMP amplifier.
