some helpful info on muti zone amps

Home Theater Receiver Function Overview

A Home Theater Receiver combines the functions of three components:

1. A tuner for AM/FM; in some cases, HD (High Definition Radio), XM or Sirius Satellite Radio, and/or Internet Radio.

2. A Preamp that controls which audio/video source is selected (DVD player, VCR, CD player, iPod, etc...), processes the incoming stereo/surround sound signals, and distributes audio to the channels and subwoofer output. Video from components (such as a DVD player) are routed to a TV.

3. A built-in Multi-channel amplifier (5.1, 6.1, or 7.1 channels) that sends the surround sound signals and power to the speakers.

However, as the sophistication of Home Theater Receivers increases, another feature that is being incorporated into many of that is referred to as "Multi-Zone Capability".

What Multi-Zone Capability Is

Multi-Zone capability is a function in which the Receiver can send a second source signal to speakers or a separate audio system in another location. This is not the same as just connecting additional speakers and placing them in another room.

The Multi-Zone function allows a Home Theater Receiver to actually control either the same, or a separate, source than the one being listened to in the main room, to another location. For example, the user can be watching a 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 DVD player and CD player are connected to the same Receiver, but are accessed and controlled separately using the same main Receiver.

How Multi-Zone Capability is Implemented

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 receiver in the 5.1 channel mode for the main room and using the two spare channels (normally devoted to the surround back speakers), as the speakers to run a Second Zone. Also, in some receivers, you can still run a full 7.1 channel system in the main room, provided you are not using the Second Zone setup at the same time.

2. In addition to the method in #1, 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 to supply a signal to an additional amplifier (purchased separately) in another room that can power an additional set of speakers. This 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 and Zone 3, in addition to the main zone. On these receivers, Preamp Outputs are provided for both Zones, which require separate amplifiers 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 a Second Zone with the internal amplifiers of the receiver, and a Third Zone using a separate amplifier. However, since 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.

Additional Multi-Zone Features

In addition to the basic ways in which Multi-Zone capability is implemented in a Home Theater Receiver, there are also some other features that may be included.

1. In many cases, while the receiver can utilize both its full audio and video features in the main room, it may be that analog audio-only functions are accessible for Multi-Zone use.

2. 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 and/or analog video connections may be accessible for use in a Second or Third zone.

3. There may be additional speaker connections on the receiver that will allow you to connect a full 7.1 Channel as well as a Second and/or Third Zone that can 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.

Having moved from a very budget sub in my early days (Robertson Audio 12") to more expensive ones as my ability to afford them went up, I have some advice for other bass lovers…. I am not expert, there are many more experienced gurus out there, but I do want to spend the least to get the right sub.

Good sub selection, plus placement and room treatment can make a lesser sub sound better, or you may also wonder why an expensive sub sounds so disappointing in your home.

Furthermore if there is going to be concurrent renovations plan ahead and integrate the home theatre system and any sound treatment into the renovation.
