AV Receivers

An AV receiver is the control centre of your home cinema: it receives picture and sound signals from source devices, decodes multichannel audio formats such as Dolby Atmos and DTS:X, distributes the picture to the TV or projector, and drives all the speakers with its own power amplifiers – all in one housing.

Why an AV receiver

If you want to cover everything from stereo to big surround sound with a single device, there's hardly any way around the AV receiver. It bundles preamp, power amplifiers, video switching and room calibration into one component. Instead of separate building blocks, you connect TV, Blu-ray player, games console and streaming box via HDMI and let the receiver handle the rest – including automatic room calibration that adapts the sound to your room.

What matters

The number of channels is decisive: 5.1 is enough for classic surround, 7.2 or more is needed for Dolby Atmos with ceiling channels. Look for enough HDMI inputs with a current standard (8K, 4K/120Hz for gaming), power per channel matched to your speakers, and a good calibration system. At HD Zürisee in Wädenswil we look together at which receiver suits your room, your speakers and your sources – and on request we take care of installation and calibration on site.

Who it's for – and straight talk

The AV receiver is for anyone who wants home cinema and music from one box, without stacking components. If you're after a pure stereo setup for music, you're better served with an integrated amplifier. If you want maximum sound in large rooms, you combine an AV preamplifier with separate multichannel power amplifiers.

Straight talk: More channels on the spec sheet don't help if the speakers and the room don't play along. Better seven well-calibrated channels than eleven badly placed ones. Manufacturers' power specs are often best-case figures – what counts is stable interplay with your speakers.

Verdict: The AV receiver is the heart of almost every home cinema – versatile, future-proof in its range of connections, and remarkably adaptable to the room thanks to calibration. The right choice stands and falls with channel count and HDMI equipment.

Frequently asked questions

How many channels do I need?

5.1 is enough for classic surround. For Dolby Atmos with height effects you need at least 5.1.2, i.e. two additional ceiling channels. More channels only pay off once the room is large enough and you can place them cleanly.

What's the difference between an AV receiver and an AV preamplifier?

The receiver has the power amplifiers for the speakers built in. The AV preamplifier doesn't – it needs separate multichannel power amplifiers. Preamplifier plus power amplifiers bring more power and flexibility, but cost more and need more space.

Do I need the latest HDMI connections?

If you want to play a current games console in 4K at 120Hz or feed in 8K, yes. For pure movie watching in 4K, older HDMI standards are enough too. We'll tell you honestly what you actually need.

What does automatic room calibration do?

It uses a microphone to measure how your room sounds and corrects the delay times, levels and frequency response of the individual speakers. This noticeably lifts the sound quality – especially in rooms that aren't optimally furnished. On request we carry out the calibration for you on site.

Can an AV receiver play music in stereo only?

Yes. Many models have a Pure Direct or stereo mode that uses only the front speakers and bypasses sound processing. However, it usually doesn't quite match the sound quality of a good, pure stereo integrated amplifier in the same price range.

Why buy an AV receiver from HD Zürisee?
