First home theater. HELP

Hi guys,

Luddite that I am, I am in the process of putting together our first home theater setup, and could use some help. It's always been about two channel/analog for me, and I am way behind the times when it comes to video. I want to keep it as simple as possible, not too expensive, and want to use some of the gear that I now use as a second system in our weekend country get-away place. I am interested in a basic surround setup (5.1), for prerecorded movie playback only (DVD's, movie downloads , but no cable or network tv), and the kids' video games. The
system will be also used for two channel music listening, which is why I would like keep the current gear and hopefully simply (?) integrate the new video and additional audio gear.

The current sound system consists of Meitner PA6i preamp and Meitner 101 mono blocks, Totem Arro speakers and EAD transport and DAC. I will probably add a turntable to the system at some point, which is one of the reasons I want to keep the Meitner gear (good phono), as well as the fact that it sounds great with the Arro's, is small and looks great.

My thoughts so far are to add a Totem Dreamcatcher center, rears and subwoofer for 5.1 use, an appropriate 5.1 surround processor, and a Meitner MTR50 stereo amp for the rear channels. Video will probably be handled by a Panasonic or Samsung 60in plasma. First question:

Is there a good, reasonably priced surround preamp that has a "pass-through" feature so that I can use the Meitner pre for two channel music listening with minimal sound degradation? BTW, the Meitner has two sets of outputs for whatever that's worth.

I have no illusions about getting sound that comes anywhere near SOTA, but would like to enhance movie viewing, and retain the sound of the existing second system for music listening. I welcome any thoughts/suggestions re processor, speakers, set-up, etc.

Thanks in advance.

Hi Frogman (and others who have responded),

I must admit that all of this leaves me totally confused.

How can the second set of outputs on the Meitner preamp provide any usefulness in this situation? The Meitner monoblock amps have to be driven by either the Meitner preamp (which presumably would give the best sonic results for two-channel listening) or by the A-V processor or receiver (at line level). The output of whichever of those two devices is not driving the power amps would have to be connected into an input of the device that is driving the power amps. In either case only one set of Meitner preamp outputs would be used.

Or is what is being envisioned connecting BOTH the A-V component and the Meitner preamp to the monoblocks, AND also connecting the Meitner preamp into the A-V component? Which wouldn't work properly, because when the A-V component is being used its output would be loaded by the low (47 ohm) output impedance the Meitner has when powered up and unmuted (or by a short to ground when powered down or muted, as you indicated). And for two-channel listening, having the output of the powered down A-V component and its cabling connected to the output of the Meitner preamp would not be a good idea either.

I do agree that unfortunately the lack of an easily repeatable means of resetting a specific volume on the Meitner preamp is a significant constraint on how the system can be configured.

Best regards,

Hi Frogman. I have integrated my two channel system with a modest surround system by using a 5.1 receiver with preamp outputs. I hooked the left/right front preamp outs from the receiver into a line level input on my 2-channel preamp. When setting the channel levels on the receiver, it is necessary to determine a position for the volume control on the two-channel preamp which you can return to when using the surround system. For me, the 12:00 position worked great and is easy to remember. This method should work with a surround processor also.

Thank you for chiming in, Al. I confess to being confused myself as to how connecting the line level front L/R outputs of the receiver to the extra output of the Meitner preamp would work; seems improbable. Nonetheless, the idea seems to be that this allows the Meitner to remain connected to the front mono's for critical music playback, and that for video, the two outputs of the Meitner, being connected in parallel, would allow the front L/R line level signals from the receiver to "pass through" from one set of RCA jacks to the other set which is permanently connected to the two front amplifiers. Please shed some light on this.

As I think about it further, why not simply send the receiver's two front channel signals to one of the aux inputs on the Meitner, which would send it to the front amplifiers? The Meitner has the capability to adjust the volume of each input relative to the other inputs. Would the volume of the two front channel signals not be controlled by the volume control on the receiver as it passes through the Meitner?

Minkwelder, just read your post, thanks for confirming what I had in mind.

It won't work. Electrically that is essentially no different than connecting the outputs of both the preamp and the receiver together at the power amp inputs, via a y-adapter. The comments in my previous post about connecting both the preamp and the receiver to the power amp apply. I would also recommend against doing that even if the preamp did not short its outputs to ground when turned off, per the reasons stated in my posts in this thread. Basically, connecting two outputs together is almost never good practice IMO.

The Meitner has the capability to adjust the volume of each input relative to the other inputs. Would the volume of the two front channel signals not be controlled by the volume control on the receiver as it passes through the Meitner?
That would be the ideal arrangement (using pre-out signals from the receiver), EXCEPT for the problem of not being able to easily return to a specific volume setting on the Meitner. Yes the volume would be controlled by the receiver, but it would also be affected by the volume control setting in the Meitner, and therefore thrown out of balance with the volume on the center and rear channels unless the Meitner's volume control could be returned to a consistent setting when the receiver is being used.

Perhaps the answer is to go the other way, as I believe you alluded to in your original post, and find a receiver or processor having pre-outs (that would be connected to the Meitner power amps) and preferably also a pass-through provision to those outputs, with the Meitner preamp's output being connected to an input of the receiver or processor. If a receiver were being used (as opposed to a processor + multi-channel power amp), it would have to provide a convenient means of disabling the center and rear channel speakers while providing normal signals to the pre-out jacks. I don't know if a beast meeting all of those requirements exists, as I don't have a lot of familiarity with A-V stuff.

Best regards,
