Do I need an Amp

[dmoss]

<font color='#000000'>I recently bot an Rx-V2400 Yamaha. &nbsp;I have 2 Paradigm Studio 100's on the way. &nbsp;Over the next couple of months I hope to purchase the Seismic 12 Subwoofer, the CC470 Center and a couple of ADP 470's with Stands. &nbsp;Is my Receiver going to be able to hand these or should I also be purchasing an amp. &nbsp;I am relatively new to this so I figured that if my Speakers rate at 150 watts or more and my receiver rates at 120 watts everything should be just fine. &nbsp;After listening to some of the conversations in this forum I am not so sure. &nbsp;Exactly what hooks up from the Receiver to the amp. &nbsp;Do you just connect the Main Speaker outs to the amp ins and then connect the Speakers or is there more to it than that. &nbsp;Can I damage my speakers or amp by improper hookup I mean is it possible to mismatch the amp with the receiver. &nbsp;I am looking for a beginning point. &nbsp;Has audioholics done any reviews on this topic? &nbsp;If so please ref to me!</font>

<font color='#0000FF'>The RXV-2400 has a real healthy amp section and unless you have a really large room or inefficient speakers, get yourself a SPL meter and see what readings you are getting, if it hits 85db with your pink noise test, you have sufficient power and no need to spend on an external amp.</font>

<font color='#000000'>With speakers like those studio's, I would recommend external amplifiaction to merit their ownership.

There is no rule stating that one must match the sub to the rest of their system. &nbsp;This is the one area where you can mix and match brands without indigestion. &nbsp;You don't have to worry about timbre matching, as the subs low frequencies don't sync up with the rest of the speakers in the same way as the others do. &nbsp;

In all honesty, I can't remember the last time I auditioned (in home) someone's system that had the sub matched to the rest of their speakers. &nbsp;Don't let this supposed &quot;matching&quot; seem like a golden rule. &nbsp;This actually limits you and keeps you from venturing out into the depths of the sub-terrainean world out there.

This siesmic sub is nice, I've auditioned it. &nbsp;But, its pricey for what it is. &nbsp;Have you looked at any other brands? &nbsp;I would at least suggest you sample some more flavors before pulling the trigger, if you haven't already. &nbsp;The siesmic sub lacks speaker level inputs/outputs or a crossover bypass as well. &nbsp;

With those studio's, you'll want a sub that can REALLY hit the low notes and not cross over too much in the upper bass regions. &nbsp;Those 100's can play fairly low on their own, and only need augmentation and support on the lowest notes. &nbsp;During 2-channel listening, a sub probably won't even be necessary, given that those 100's get ample power. &nbsp; &nbsp;

Velodyne has some nice stuff, as does sunfire also. &nbsp;For $1600, I'd definitely do some shopping around.

From one 2400 owner to another, you'll never see 120 ample watts from this unit, or get your money's worth out of those studio's without external amplification.

<font color='#0000FF'>While on subject of amps, ebay lists MX-1 at $700 and it is a perfect compliment to your Paradigm, one forum member here has already traded his monoblocs for the MX-1 and he too has Paradigms.

Also on the sub front, check out Yamaha's YST-SW1500, real mighty sub but with surprising musicality.</font>

<font color='#000000'>An external amp doesn't necessarily need to &quot;match&quot; up with the receiver or pre/amp. &nbsp;There are universal connections called line-level (RCA jacks) that connect an amp to a receiver or pre/pro. &nbsp;Nothing about the amp can really damage or meddle with the processor attached to it. &nbsp;Please don't be timid about such a hookup, its not that complicated once you see it or do it for yourself. &nbsp;Its almost plug-n-play simple. &nbsp;

Damaging your speakers can be done much easier with your 2400 than an external amp...surprised? &nbsp;Clipping, distortion, lack of power, cats, ball ping hammers, and laser cannons are the leading culprits in the damaging of speakers. &nbsp;You can almost never feed a speaker TOO MUCH clean power. The drivers on the speaker(s) will simply exhibit more control, stabilitiy, better response, etc. &nbsp;If the amp has so much more power than is necessary, you would never crank it up so high that the extra or reserve power would damage anything, your ears would bust long before this occured. &nbsp;

You probably won't be implementing bi-amping (active or passive) in your setup, but you will still need strong external amplification in order to control all those passive electronics inside those studio's. &nbsp;Some don't realize that the passive cross over networks inside a speaker can eat up to and in excess of half the incoming juice. &nbsp;YIKES!!! &nbsp;

Once you have the line-level (RCA jacks) connections between the amp and processor (or receiver) you will simply connect the speakers to the amp via speaker cables...easy enough eh! &nbsp;

In order, receiver---amplifier(s)---speaker(s).

<font color='#000000'>Went to ebay. Didn't see MX-1 atleast not an amp.  I don't understand.  If a receiver is rated at 7 x 120 watts why can't it achieve that.  Why does the amp do what the receiver can not?   What is the differenc between a 5 channel descrete and a regular 5 channel?</font>

<font color='#000000'>If you look at Gene's review of the spl-1200 it turned into a promotional for the Seismic 12. &nbsp;When someone sends it back it really makes me wonder. &nbsp;Paradigm is expensive, &nbsp;but it appears from most of the input I am receiving on these forums to be the better product.</font>

<font color='#0000FF'>There were qutie a few of them in the last few months but all of them seem to have been lapped up, you can also check out the MX-2 as well as MX-1000 which is basically the older model of MX-1 with VU.</font>

<font color='#000000'>I would recommend at least checking into this sub.

It is an absolute animal, and with a brand new built in equalizer and all the flexibility you'll ever need. &nbsp;

Sunfire True Sub EQ

7x120 does not mean a simultaneous 120 watts being driven to all channels at the same time. &nbsp;It simply means that any one channel, has a maximum potential of 120 watts peak by itself. &nbsp;The method in which you read the spec sheets, is exactly what the marketing boys would like for their potential customers to interpret and assume. &nbsp;

Its just advertising...and hype...don't worry, most companies do the exact same thing...I apologize if I'm the bearer of bad news...

<font color='#000000'>Theres an MX-1000u on ebay now. Looks like it has 3 channels. Is what you are talking about?</font>

 

[Yamahaluver]

<font color='#0000FF'>Hi dmoss,

The MX-1000U (U=USA) is strictly 2 channel amp with HCA class A operation delivering 260W rms into 8 ohms and capable of 1000W into 1ohms. It has twin 750VA transformers making it a dual mono design.</font>

<font color='#000000'>Get an amp atleast to power the 100's and CC470, leaving the Yamaha to power the rears. &nbsp;Personally I have a Rotel RMB-1095 powering my Studio40/20/570. &nbsp;Sound is &nbsp;

Bot and amp

Just bot the ati at2505, probably not the very best but the price was definitely right. Think it will more than meet my needs. Using to run 3 front speakers of Paradigm Studio 100 and cc570 Center.
