2. Overview
The 1 x 7-Zone Audio Module links up to seven pairs of
speakers to a single input source. It works with standard
stereo speakers and has screw-type connectors. This
module should be installed in one of the Pure Home
Networking Boxes (JHN1014A, JHN1020A, JHN1030A,
or JHN1040A).
3. Installation
3.1 Tools You’ll Need
• Wire strippers
• Small standard screwdriver
3.2 Cable Handling Guidelines
• Do not route telephone cables through the same
cable holes as the AC power cables.
• For safety, separate all telephone cables from
parallel AC power lines by at least 6 inches
(15.2 cm) whenever possible. Avoid kinking the
cable.
• Do not attach cable tie-downs too tightly. The
cable-fastening hardware should not compress
the cable sheath.
• Do not bend the cable sharply. Place the cables
properly in the cable management after passing
them through the holes, since the edges of the
hole can compress or damage the cable sheath.
• When installing an individual module in the Pure
Home Networking Box, place it above or below
the interfacing module (if possible). This will
eliminate excessive cable crossing.
• For your safety, do not use this or any electrical
product near water (unless it is specifically
designed for wet areas). Do not install wiring
during thunder and lightning storms.

3.3 Attaching a Module to the Module Bracket
Using the MDU Module Bracket with (2) MDU and
(1) CATV Module Openings, 1 Unit, Full Size
(JHN2030A) is optional. To install it, snap the module
into the bracket. Then press the pushbuttons on the
bracket to lock the module in place. If you choose not
to use the module bracket, go straight to Section 3.4.
3.4 Installing a Module in the Pure Home Networking Box
1. Determine the area for installation.
2. Position the metal tabs on the left side of the
module at a 45-degree angle and slide them into
the rail holes on the Pure Home Networking Box.
3. Insert the metal tabs on the right side of the
module into the rail.
4. Press the button to fasten the module to the Pure
Home Networking Box.
3.5 Removing a Module from the Pure Home Networking Box
1. Press the button and hold it in while pulling the
module from the Pure Home Networking Box.
2. Swing the module out.
3.6 Basic Configuration
The audio module supports up to 7 zones from one
single source. A zone is defined as a set of speakers.
1. Using the appropriate wire stripping tool, strip
the speaker cable to 1⁄2inch (1.3 cm).
2. Connect the right and left output from the main
audio source to the module’s right and left
input screw-down terminal.
3. Connect speaker cables to the right and left
outbound screw-down terminals leading to the
speakers or volume controllers.
4. Join the cables neatly together with cable ties using
the cable management channel anchoring
points.
NOTE
Be sure to correctly connect the positive and negative
speaker wires. Cross-connection will result in distortion and
poor sound quality.
