How to Wire Your Home Theater for Dolby Atmos on a Budget

Introduction

Installing a Dolby Atmos home theater can seem intimidating, especially if you're trying to do it affordably. However, with some planning and effort, it is possible. In this guide, I'll walk you through the basics of wiring a Dolby Atmos home theater on a budget.

Equipment Needed

Here is the basic equipment you'll need:

• AV receiver - This is the heart of your home theater system. Look for one that supports Dolby Atmos and has at least 5.1.2 channels. Entry-level models start around $300.

• Speakers - For a basic 5.1.2 Dolby Atmos setup, you need left, center, right, surround left, surround right, and two height channels (also called Dolby Atmos enabled speakers). Start with bookshelf speakers, which are cheaper. Plan to spend $75-150 per pair.

• Speaker wire - Use 16 or 14 gauge oxygen-free copper wire. You can find spools of it for around $40.

• RCA cables - To connect your AV receiver to your TV/media sources. Budget $1-2 per cable.

• Speaker wire terminals - Banana plugs or pin connectors make connecting wires to speakers easier. About $10-20.

• Conduit and wall plates - For running speaker wires through walls. Around $20-40 total.

Planning the Installation

Proper planning is crucial for a clean, functioning system. Here are some tips:

• Make a sketch of your room including speaker placements following Dolby Atmos guidelines.

• Measure wire runs and add 2-3 feet extra per run.

• Plan conduits/wire routes avoiding sources of EMI like appliances.

• Label wires and terminals to avoid confusion.

• Consider buying wire in bulk and use coupon codes when purchasing gear.

Running the Speaker Wires

Here is how to neatly run the speaker wires:

• Use conduit to protect wires going through walls. Feed wire through carefully.

• For surface wiring, adhere wire to baseboards/ceiling with clips. Avoid high traffic areas.

• Label wire ends clearly (+ and -) with tags. Tape ends for safety.

• Leave ~6 inches of extra wire at the end of each run for connections.

• Test each wire run for continuity before connecting anything.

Connecting the Equipment

Follow these steps to connect up your system cleanly:

• Attach banana plugs or pins to wire ends. Follow labeling system.

• Connect wires to corresponding speaker terminals tightly. Observe polarity.

• Neatly organize wires at the back of the receiver using velcro ties.

• Plug source devices like Blu-ray player into proper input jacks.

• Use HDMI cables for video sources and digital audio connections.

• Connect TV using HDMI ARC input to simplify cabling.

Configuring the AV Receiver

To finish up:

• Set up speakers according to their positions in the Dolby Atmos speaker layout.

• Adjust speaker distances so sounds from different speakers arrive simultaneously.

• Set speaker sizes depending on the type of speakers used.

• Adjust listening mode for Dolby Atmos playback.

• Fine tune with speaker calibration tones.

• Enable HDMI Control to automatically switch inputs.
