How to Set Up a Home Cinema System with an AV Receiver: A Step-by-Step Guide

You've bought an AV receiver, a set of speakers, and a display. Now you need to actually make them work together. This is the step-by-step guide to setting up a home cinema system with an AV receiver — the wiring, the configuration, the calibration, and the small choices that decide whether the system sounds great or just okay.

For the planning step before this (room, screen, speaker layout, receiver choice), see our home cinema setup guide. For receiver picks themselves, see our best AV receiver buying guide.

Step 1: Position the Speakers First

Before any cable goes anywhere, place the speakers. Get this right and everything else gets easier:

• Front L and R — equal distance from the centre of the screen, angled slightly inward toward the main listening position. Tweeters roughly at ear height when seated.
• Centre — directly below (or above) the screen, on-axis with the listening position. Aim it slightly upward if it's below ear height.
• Surrounds — to the sides of the listening position, roughly at ear height or slightly above, ideally angled to fire across the seats rather than directly at them.
• Rear surrounds (7.x systems) — behind the listening position, roughly equal distance apart, similar height to side surrounds.
• Heights/ceiling speakers (Atmos) — follow Dolby's recommended positions. For full placement detail, see our Dolby Atmos speaker placement guide.
• Subwoofer — corner-loaded boosts bass; mid-wall placement is more even. The 'subwoofer crawl' (put the sub at your seating position, play bass, walk the room, place the sub where it sounded best) finds the best location for your specific room.

Step 2: Wire the Speakers

Keep speaker wiring tidy from the start — the time spent here pays back forever:

• Maintain polarity. Every speaker has a + and − terminal. Wire them the same way at both ends. A swapped speaker sounds 'off' in ways that are hard to diagnose later.
• Use adequate cable gauge. For runs under 5m, 16AWG is fine. Over 5m or for heavy bass, step to 14AWG or 12AWG.
• Banana plugs or bare wire — either works. Banana plugs are tidier and easier to disconnect; bare wire is cheaper. Don't use one without proper preparation — fraying causes shorts.
• Label both ends with the channel (FL, FR, C, SL, SR, etc.). When something needs troubleshooting later, you'll thank yourself.

Step 3: Wire HDMI

HDMI is the spine of the system. A few principles save trouble:

• All video sources go into the receiver. Console, Apple TV/4K streamer, Blu-ray player, set-top box — each into an HDMI input on the receiver.
• One HDMI cable goes from the receiver to the display, ideally to the display's HDMI 2.1 / eARC input.
• Use cables rated for your bandwidth. 4K/60Hz HDR needs 18Gbps (HDMI 2.0). 4K/120Hz HDR, 8K, and full Dolby Atmos via eARC need 48Gbps (HDMI 2.1). 'Ultra High Speed' certified cables are the safe choice for 2.1.
• Keep cable runs short. Long passive HDMI runs (over 5m) get unreliable at high bandwidth. For longer runs, use active optical HDMI.

Step 4: Connect the Subwoofer

The sub connects to the receiver's subwoofer pre-out (SW or LFE) via a single RCA cable. Two notes:

• Use a proper sub cable — a basic RCA is fine for short runs; for longer runs use a shielded cable to avoid hum.
• Set the sub's own crossover dial to maximum (or 'LFE'). The receiver handles the crossover, and having both filters active causes a notch in response.

For multiple subs, modern Audyssey, ARC, and Dirac all support independent calibration of each sub, which is significantly better than running two subs in mono. Use separate pre-outs if your receiver has them.

Step 5: Set the Speaker Configuration in the Receiver

Power on. In the receiver's setup menu, tell it what speakers are connected:

• Set channel configuration (5.1, 5.1.4, 7.1.2, 7.1.4, etc.)
• Set each speaker's size: Small for everything but the largest floorstanders, regardless of how big the speaker actually is. 'Small' means 'send the bass below the crossover to the subwoofer'. This dramatically improves the system's headroom and bass cleanliness
• Set crossover frequencies: 80Hz is the THX-recommended default and works for most modern speakers. Smaller speakers may need 100–120Hz
• Confirm the subwoofer is detected and on

Step 6: Run the Auto Room Correction

Every modern AV receiver includes auto room correction — Audyssey (Denon/Marantz), Dirac Live (high-end Denon/Marantz, NAD, others), ARC Genesis (Anthem), or YPAO (Yamaha). This is the single largest free sound quality improvement you'll make. To do it well:

1. Quiet the room. Fridge off, fans off, windows closed, no people moving.
2. Mount the microphone at ear height at the main listening position. Most kits include a small tripod or table mount — use it.
3. Take multiple measurements. Most systems prompt for 6–8 positions around the seating area. Do them all — not just one.
4. Don't shortcut. Audyssey/ARC/Dirac calibrations take 20–40 minutes and require patience. Skipping positions or rushing degrades the result.
5. Save the result. Most systems let you save the calibration profile. Do it.

For serious results, a measurement-grade microphone (UMIK-1) plus a Dirac Live upgrade if supported by the receiver is the single biggest sound improvement after the speakers themselves.

Step 7: Check and Adjust by Ear

Auto-calibration is a starting point, not a finish line. After it runs:

• Play known reference material — a film you know, a music track you know. Listen for tonal balance, dialogue intelligibility, surround envelopment.
• Adjust subwoofer level by ear. Auto-calibration sometimes runs subs hot or cool. Trust your ears for the final 2–3dB of trim.
• Listen at different volumes. A system that sounds great loud should also sound balanced quiet — if it's mush at low volume, something's wrong with the bass crossover or sub level.

Step 8: Configure HDMI and Audio Pass-Through

In the receiver settings:

• Enable HDMI eARC on the output to the display. This carries Atmos and high-bitrate audio back from apps running on a smart TV.
• Set HDMI input/output naming so the inputs read 'PS5', 'Apple TV', 'Blu-ray' instead of HDMI 1/2/3.
• Enable 4K/120Hz pass-through if you have a gaming console and a compatible TV/projector.
• Disable any extra processing modes you don't need — Pure Direct or Pure Audio for stereo music; turn off DSP enhancements for film content unless you specifically prefer them.

Step 9: Network the Receiver

Connect the receiver to your network — wired Ethernet is far more reliable than Wi-Fi. This enables firmware updates, streaming services, AirPlay/Chromecast, and multiroom features. Run firmware to the latest version once connected.

Step 10: Document the Setup

Five minutes of documentation now saves hours of troubleshooting later. Write down:

• Which source is on which HDMI input
• Speaker channel labels and cable colours/IDs
• The calibration profile name you saved
• Any non-default settings you changed

Common First-Time Setup Mistakes

• Setting speakers to 'Large' in the receiver because the speakers are physically large. Almost always wrong — set to 'Small' and let the sub handle bass.
• Leaving the sub's own crossover engaged. Causes a notch in bass response. Set sub's crossover to maximum.
• Skipping room correction or running it once carelessly. The biggest free improvement — don't skip it.
• Cheap HDMI cables on long runs. Intermittent dropouts and 'no signal' issues almost always trace back here.
• Mismatched speaker polarity. Imaging sounds vague and bass thins out. Check + and − at every connection.

The Order Matters

Speakers placed → cables run → sources connected → configuration set → room correction → listen and adjust. Skip steps or do them in the wrong order and you'll spend more time troubleshooting than enjoying the system.
