w3wilkes 15 Posted Thursday at 10:09 PM Posted Thursday at 10:09 PM Hi all, I'm old and retired but have always thought Carver had great products! I'm looking to get a preamp and amp. Been looking at the M1.0t amp and notice there's a pre and post version from serial # 4500. The post 4500 serial # has a switch for mono vs stereo that isn't on the pre SN # 4500 units. If connecting 2 speakers (stereo) should the + and - match or are the left and right channels out of phase? If out of phase, should one of the speakers be connected reversed? Wilkes 5
BobTFM35 3,056 Posted Thursday at 11:23 PM Posted Thursday at 11:23 PM (edited) @w3wilkes Welcome to the Carver Site!! If I was getting either one or two M1.0t, I would get them with the option to switch between mono and stereo. This way I can enjoy the versatility it affords me in the way it can be deployed in my system. Also checkout the manual that available on the website for more information. When its hooked up as a mono amp the speakers are hooked up differently. Edited Friday at 01:06 AM by BobTFM35
Sk1Bum 12,859 Posted Thursday at 11:41 PM Posted Thursday at 11:41 PM Hello Wilkes and welcome to thecarversite.com. Glad you found us! The model without the switch is inverting, and the one with the switch is non-inverting. I believe the non-inverting model is common ground, hence the different terminal placement. You should hook up your speakers like the diagram on the back of the amp. There are diagrams for both stereo and mono (bridged) speaker connections. I hope that helps. 1

If out of phase, should one of the speakers be connected reversed? The outputs for the right channel are reversed inside of the amp. In other words, for the inverted right channel the signal goes to the black output post and the ground goes to the red. Hook speakers up normally. This is normally not an issue, unless you have a Polk SDA speaker system, or any other system that requires a "common ground". Edited Thursday at 11:42 PM by timmyjim 2
w3wilkes 15 Posted Thursday at 11:56 PM Author Posted Thursday at 11:56 PM Thank you all. My use would be a single amp with 2 speakers (ADS L810's) attached left and right. Just hook them up per normal + to + and - to - for both left and right on the pre 4500 amp or the same on a newer than 4500 amp with the switch in Stereo position, correct? 2
w3wilkes 15 Posted Friday at 12:04 AM Author Posted Friday at 12:04 AM I'm also thinking of trying Sonic Holography. The C1 preamp seems like it would be just fine for me. In reading the C1 manual it sounds like the use of SH requires specific positioning of the speakers in relation to the listener and would be more for "individual critical listening". Then for casual listening in a social setting it would probably be best to shut off SH. Does this make sense? 2

If you like Sonic Holography, it won't hurt to leave it on all the time. If you don't like Sonic Holography, it won't hurt to leave it off all the time.

Then for casual listening in a social setting it would probably be best to shut off SH. Does this make sense? Sonic Holography is fairly position sensitive. The implementation relies on slight difference in time between when each ear hears sound from the same speaker. In order for the delays to make sense, you have to physically be in a certain distance relationship to the speakers. There is always a sweet spot. It would not be used in a social setting. SH can be good for some recordings and not-so-good for others. 1 hour ago, w3wilkes said: Thank you all. My use would be a single amp with 2 speakers (ADS L810's) Love those speakers. 2
w3wilkes 15 Posted Friday at 02:32 AM Author Posted Friday at 02:32 AM Thanks again to all for your answers and input! Always wanted a little more power than my old Kenwood KA-405 55 watt integrated amp to drive my old ADS-L810's and now in a position to afford an upgrade. Just pulled the trigger on a Carver C1 preamp and a Carver M-1.0t with the switch on the back. Over the years I've read a bunch of stuff on Bob Carver, gear designs and some the challenges he gave to the "tube purist's". So looking forward to hooking these up! Would it be better to stack the amp on the preamp due to heat from the amp, seems to make sense? Wilkes

The M1.0t and M500t won't stack well on top of a C1. The C1 isn't as deep, and the back feet on the amp will be hanging off in the air. If you have to stack them, the C1 will stack much better on top. 2
w3wilkes 15 Posted Friday at 02:46 AM Author Posted Friday at 02:46 AM Thanks, didn't realize the pre was less deep than the amp. I think I can put the pre on a shelf above the amp. 2
w3wilkes 15 Posted Friday at 02:51 AM Author Posted Friday at 02:51 AM (edited) Wondering if there's many of you Carver folks using Squeezebox? I've been in the SlimDevices - Logitech Squeezebox - now Lyrion music world since 2008 for all my digital music. Wilkes Edited Friday at 05:10 PM by w3wilkes
