MC601 power consupmtion.

[musicman59]

Does anybody know the actual power consumption of each MC601?
I am looking into a power conditioner that has an isolation transformer of 5 Kva and I don't know if it can support both amps because I have not been able to find the actual power draw.

Thanks.

Jose.......The full load current of the MC601 is 6.6 amps at 120 volts. A pair of 601's would draw 13.2 amps at full rated output. What's important to understand is it is highly unlikely that the MC601 will ever demand 6.6 amps since music is not a continuous tone but many peaks and valleys. A fleeting 600 watt peak would most likely demand less that the 6.6 amp full load current because the demand is so fleeting. I measured my pair of MC601's together and found that at 200 watt peaks the amplifiers were drawing less than 7 amps total. That equates to approximately 840 watts of demand. Both of my MC601's are powered from a single PS Audio Power Plant Premier which can deliver 1400 watts continuous power to the amplifiers. I have never had any issues with current delivery no matter what volume level I drove the amplifiers.

Your 5Kva isolation transformer should easily handle loads that would exceed 30 amps at 120 volts without any problem.

love this place

I learn so much.

Thanks for the information Dan! It is very helpful!!!

Dan,
Currently I have 3 dedicated 20 amps lines for my system. One for each MC601 and a third one for the C2300, Bricasti M1, Wadia 20 Transport and Mac Mini Server.
If I get the conditioner I will have to put everything on one line. Do you think it will be ok?

As long as the power conditioner has a cap bank you should be fine, some are just in-line conditioners with little reserve power.

The 2300 pulls around 75 watts max, the extra equipment you mention pull not that much (less than 200 for the other equipment total).

I'm running two MC601s, an oppo bdp-95, Denon pre-amp, and a projector through a conditioner. As shown in the other thread, the only issue I have is upon startup (tripping the GFCI). The whole setup with pretty loud playback (6watt rms, and around 80-100 peak from each MC601) is showing a total of 7 amps RMS draw.

The MC601s sink a ton of power to charge up their caps, so that initial hit is the only thing to worry about.

Now I need to fix my own issue . . startup transients

The conditioner does not have caps. It has a 5 Kva toroidal isolation transformer and some Rick Schultz's magnetic wave rectifiers. I can post a picture of the inside if you can tell me how.

Jose.......A single dedicated 20 amp circuit will be satisfactory for your total connected load. If you wish to separate the power amplifiers from the preamp and sources you can use two of your dedicated circuits, one for the 5Kva isolation transformer and power amps, and the second circuit with a smaller power conditioner for the remaining gear.
