Home Theater Receivers and the Multi-Zone Feature

How to use one home theater receiver in more than one room

A home theater receiver performs several important functions in a home entertainment.

It is used as as a tuner for AM/FM, Satellite, or internet radio. It works as a preamp to controls which audio/video (AV) source is selected, such as a Blu-ray Disc player, DVD player, VCR, CD player, or Media Streamer. And it functions as a multi-channel amplifier that processes and sends sound signals and power to the speakers or subwoofers. Video from sources components can also be routed through the receiver to a TV if desired.

In addition, many home theater receivers serve as a multi-zone audio distribution system.

What Is a Multi-Zone Audio Receiver?

Multi-Zone is a function that allows a home theater receiver to send a second, third, or fourth source signal to speakers or separate audio system in different locations.

This is not the same as connecting additional speakers and placing them in another room, nor is it the same as Wireless Multi-room Audio. Multi-Zone home theater receivers can control either the same or a separate source than the one being listened to in the main room, in another location.

For example, the user can watch a Blu-ray Disc or DVD movie with surround sound in the main room, while someone else can listen to a CD player in another, at the same time. Both the Blu-ray or DVD player and CD player are connected to the same home theater receiver but are accessed and controlled separately via additional onboard or remote control options available on the receiver.

How Does Multi-Zone Work?

Multi-Zone capability in home theater receivers is implemented in three different ways:

  1. On many 7.1 channel receivers, the user can run the unit in the 5.1 channel mode for the main room and use the two spare channels (normally devoted to the surround back speakers), to run speakers in a second zone. Also, with some receivers, you can still run a full 7.1 channel system in the main room, provided you are not using the second zone set up at the same time.
  2. Many 7.1 channel receivers are configured to allow a full 7.1 channel mode for the main room but provide an additional Preamp Line Output. This output supplies a signal to an additional amplifier in another room that can power an additional set of speakers. It allows the same Multi-Zone capability but does not require sacrificing the full 7.1 channel experience in the main room in order to get the advantages of running a system in a second zone.
  3. Some high-end home theater receivers incorporate the ability to run both a Zone 2, Zone 3 or even a Zone 4. On these receivers, preamp outputs are provided for all of the additional zones, which require separate amplifiers and speakers for each zone. However, some receivers will give you the option of running either Zone 2 or Zone 3 using the built-in amplifiers of the receiver. In this type of setup, the user can run the second zone with the internal amplifiers of the receiver, and a third or fourth zone using a separate amplifier. If you are using the receiver to power the second zone, you will still sacrifice the full 7.1 channel capability of the receiver in the main room, and have to settle for 5.1 channel use. In rare cases, a high-end receiver may provide 9, 11, or even 13 channels to work with for both the main and other zones; this decreases the number of external amplifiers you might need for other zones.

Additional Multi-Zone Features

Multi-Zone receivers may include a variety of interesting features, such as the following:

  • Analog audio: While the receiver can utilize both its full audio and video features in the main room, it may be that analog audio-only, or analog+internet radio functions are accessible for Multi-Zone use.
  • Multiple HDMI outputs: HDMI If video functions are accessible for Multi-Zone use, they may be limited to composite video signals. What this means is that while you may be able to access a full high-definition video and surround sound audio source in the main room, only components connected to the receiver using analog stereo or analog video connections may be accessible for use in a second or third zone. However, it is important to note that in some higher-end receivers, it is possible that a component video or HDMI output may be provided for Zone 2 use. If these options are important to you, make sure you check before you buy.
  • Zone-switching function: There may be additional speaker connections on the receiver that allow you to connect a full 7.1 Channel as well as a second or third zone to be powered by the receiver's internal amplifier. However, in this type of setup, if you are listening to the main zone in full 7.1 channel surround sound, you cannot use Zone 2 and Zone 3 at the same time. What happens when you want to access either Zone 2 or Zone 3? You will need to switch, via the receiver's operating menu, from a 7.1 channel main zone to 5.1 channels, enabling the extra two channels to power either Zone 2 or Zone 3 speakers. Some home theater receivers perform the above-described switching function automatically when the second zone feature is activated.

Using 2 Zones in the Same Room

Another interesting way to use the Multi-Zone capable home theater receiver is to use the second zone option in the same room as a 5.1/7.1 channel setup. In other words, you can have a dedicated 2-channel, controllable, listening option in addition to a dedicated 5.1/7.1 listening option in the same room.

How this setup works is that you would have the home theater receiver setup with a 5.1 or 7.1 channel configuration with 5 or 7 speakers and a subwoofer that you use primarily for home theater listening. Then you would have an additional external power amplifier that is connected to the receiver's Zone 2 Preamp Outputs, if the receiver provides this option. The external amplifier would be further connected to a set of front left and right front speakers that you specifically use for two-channel audio-only listening.

This setup option would work for audiophiles that want to use a higher-end two-channel stereo power amplifier and speakers for audio-only listening, rather than using the front left/right main speakers as part of the 5.1/7.1 channel setup. However, in a multi-zone capable home theater receiver, both systems can be controlled by the same receiver's preamp stage.

You don't have to have both the main and second zone features running at the same time. You can lock in your two-channel source (such as CD player or Turntable) as your designated source for Zone 2.

Many think that Zone 2 can only be used in another room, but that is not the case. Using the second Zone in your main room can allow you to have an independently dedicated (and controllable) two-channel audio system in the same room.

Of course, this setup adds a little more speaker clutter to your room, as you would have two physical sets of front left and right speakers. You would also not be using both systems at the same time since they are intended to be used with different sources.

Other Factors to Consider Using a Home Theater Receiver in Multi-Zone Setups

The concept of plugging into and controlling all of your components with one home theater receiver is a great convenience, but when it comes to Multi-Zone capability there are still other factors to consider:

  • Unless your receiver comes with a secondary remote control for use in a second or third Zone, you will have to go to the receiver in your main room to switch sources. 
  • Even if a secondary remote control is supplied for second or third zone use, you will have to install remote control extenders in the second or third zone rooms in order to use the remote in those rooms to control the source you want to access from the main receiver.
  • Whether you are using the home theater receiver to power your second or third zone speakers, or using the preamp outputs of the receiver to supply an additional amplifier in the second or third zone, you have to have either speaker wires or audio/video cables running from the main receiver to the second or third zone locations.

The Wireless Multi-Room Audio Option

Another option is wireless multi-room audio. This type of system utilizes a properly equipped home theater receiver that can transmit audio wirelessly from designated sources to compatible wireless speakers placed around the house.

Most of these types of systems are closed, meaning that only specific brands of wireless speakers will work with specific branded home theater receivers and sources. Some of these systems include Sonos, Yamaha MusicCast, DTS Play-Fi, FireConnect (Onkyo), and HEOS (Denon/Marantz)

Some home theater receivers include both Multi-Zone and Wireless Multi-Room Audio features.

The Bottom Line

For full details on how a specific home theater or stereo receiver implements its own Multi-Zone capabilities, you should consult the user manual for that receiver. Most user manuals can be downloaded directly from the manufacturer's website.

It is important to note that home theater or stereo receivers that have Multi-Zone capability are intended to be used when only a second or third location for music listening or video viewing is needed. If you want to install a whole-house wired audio or AV system using your home theater receiver as the control point, then you should consult a professional home theater or multi-room system installer to assess your needs and provide specific equipment suggestions.
