View Full Version : Can SMS-1 take two sources?

I just purchased a new SSP it's the Marantz AV8003. I have an existing Denon 5900 and I would like to run both units subwoofer out to the SMS-1. Can this be done? If so would it be better to use one balanced in and one coax in or could I use both coax inputs one for each unit?

How would you control its volume in coordination with the other channels?

Good question Kal! Actually I didn't think of the volume part. Sorry but it seems that I really didn't think this through enough before asking for help. The sub output of the Marantz goes to the SMS-1 no matter what input I use including analog 7.1 dah :confused: So as long as I don't use the Marantz EQ feature I should be able to do an exact audio comparison of the Denon vs the Marantz by just switching the inputs back and forth from digital coax to analog 7.1. Oh I will need to make sure my channel levels are all the same including the sub but I should be able to do that using my Radioshack digital sound meter right?

??? Why are you comparing a Denon player with a Marantz pre/pro? What's the point?

Kal,

Excuse me if I'm an idiot and I'm not being facetious because I've been known to be! Maybe I'm just not being clear enough. The point in my mind is to hear which unit produces better 2 channel sound from Redbook CD's. With my Denon 3805 that I used as a pre/pro before I purchased the Marantz the 5900 sounded better. I have a feeling it still will at least before I start playing with the Marantz's EQ. I plan on adjusting it using the Room EQ Wizard you suggested in another thread. So I will revisit the comparison again after I do that. I'm expecting that learning how to use the Room EQ Wizard will take me quite some time.

You say that with the older AVR, the 5900 sounded better. Better than what?

The Marantz' EQ (Audyssey MultEQ) can only be manipulated by following the prescribed procedures using the mic provided by Marantz. REQW might be fun and educational.

Wow We must be living in different galaxies !!! :) The 5900 sounded better than the old processor. In other words CD's sounder better when using the 5900 for processing verses the AVR for processing.

I won't initially be using the auto AudysseyEQ feature. I will be using a different mic, preamp, and REQW software to manually adjust the Marantz's EQ settings.

Well, I did not hear you say that explicitly. That's entirely possible.

And now you want to do the same with the Marantz? OK, feed the 5900 via analog and via S/PDIF to the Marantz, use the Pure or Direct setting and switch between them. That should tell you what you want to know. I must say, however, that the fly in the ointment is that using the analog inputs to the Marantz will severely limit the use of its DSP including bass management and Audyssey.

The manual EQ in the Marantz, as well as what is in every AVR I know of, is vastly inferior to Audyssey or other systems (such as YPAO and MCACC). Not worth the candle.
