keithfox81 Posted January 21, 2022 Share Posted January 21, 2022 Hi, new to the community. Hoping I could get some advice/help on a possible project. Right now I have a pair of La scalas into a McIntosh ma 6100. I’ve been thinking about trying to get ahold of a single heresy to use as a center 3 channel setup. My system is used only for playing audio, not home theater. I have a spare McIntosh ma5100, as well as the above mentioned ma6100. I would like to keep the la scalas hooked to the ma6100 as a 2 channel setup. The 3rd channel would be independently hooked to the ma5100 with the mono setting. Keeping the 2 channel la scala setup as the main player, turn on the 3rd channel when the mood strikes. I would need independent control of the volume, tone settings etc, between the pair of la scala, and the single heresy, if that’s possible? I used to have a 90s kenwood receiver that I briefly used as a 3 channel setup where I could adjust the volume, tone, of each speaker independently. Basically that’s what I’d like to achieve, but with 2 separate integrated amps. Is there a easy way to do this? 1 Quote Link to comment Share on other sites More sharing options...
JohnA Posted January 21, 2022 Share Posted January 21, 2022 A few old Macs has a derived center channel out at preamp level. Does either of yours? If not, Mr. Paul sketched up a line level box to derive the center channel and that could feed your 5100 to control the center. I would link to the Dope From Hope had I found it. I will also recommend you rework the Heresy's crossover to be as much like your La Scala crossovers as possible and drop the taps of the squawker and tweeter on the autoformer one step to flatten the Heresy's response curve. I have done both on my HT center channel Heresy. 1 Quote Link to comment Share on other sites More sharing options...
keithfox81 Posted January 22, 2022 Author Share Posted January 22, 2022 Thanks John, I’m not sure if I can do that with my Mac. That would be perfect if I could. I’ll look into that. I seem to recall the device you’re referring to. I first heard about it a couple month ago when researching 3 channel. It had a name like “the little box” or something similar?

Racer X Posted January 24, 2022 Share Posted January 24, 2022 I used a pair of Cornwall IIs between my LaScalas for a long time to fill out the middle. Just used one stereo amp as I found the level of 2 CWs was fairly matched to the LS. If you want separate volume, tone for the middles, you will need a second integrated amp. More recently I've found a very well set up stereo array will out perform the additional speakers in terms of strong center image. Room treatments go a very long way towards this end.

Moderators Travis In Austin Posted January 25, 2022 Moderators Share Posted January 25, 2022 Here is the schematic and everything you need to know about this subject (on a wired box by PWK). If you want to go active with timedelay you would need some input from the technical guys around here.

baron167 Posted January 25, 2022 Share Posted January 25, 2022 You can run your 1 to be purchased Heresy or other speaker off your extra ma5100 using the Mode Selector set to Mono (L+R). Pretty easy. Quote Link to comment Share on other sites More sharing options...

keithfox81 Posted February 6, 2022 Author Share Posted February 6, 2022 Thanks for all the replies, sorry about the delay in responding. After talking to few people I’m leaning forwards just keeping a 2 channel setup. I kinda like member 001 suggestion of adding a pair though. How would you configure that? 1 in each of the 4 corner? The heresy stacked on there side, on top one another, in the center. Or, a heresy on top of each la scala? On a side note I’ll be uploading some pictures of my restoration when it’s complete. I have a pair of 1990 black la scala that I’ve since veneered, added bass reflex box, separated the top from the bass bin, installed crites crossover, swapped the horn for altec 511s Quote Link to comment Share on other sites More sharing options...
JohnA Posted February 24, 2022 Share Posted February 24, 2022 A pair of speakers used as a center would suffer bigly from interference and comb filtering. Quote Link to comment Share on other sites More sharing options...
