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 amplifer.
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.

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.

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.

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.
