Do you connect your amp to your power conditioner?

I wouldn't rely on a power conditioner/regulator to be your first line of defense when it comes to surges. Get a decent surge protector installed at your main power panel. There's a few threads here on AA talking about doing just that. It's cheap insurance and in my opinion a must have.

The Ditek DTK-120/240HD2 and Eaton CHSPT2ULTRA are both good choices.

Everything plugged into an Equi=Tech 5RQ (5kVA, 240 volt/30 amp) balanced power unit which outputs 2 x 20 amp 120 volt circuits and 1 x 10 amp 120 volt circuit.

My almost 9 year old MC2301's feed from their own dedicated 20 amp breakers. They love being fed direct AC (and to the point)

My 601s are plugged into a Shunyata Denali conditioner which is plugged into a 20 amp dedicated circuit.

With Isotek power conditioners I have found that all my gear, amp include sounds even better plugged into the conditioners. For the amp I utilize and Isotek EVO3 TITAN.

Hmmmm, this doesn't sound quite right. How can you get two 120V 20A circuits + one 120V 10A circuit from one 240V 30A circuit? They can't possibly be truly independent circuits, correct?

How do you get multiple 120 volt circuits from your single 240 panel ?

The Equi=Tech ties into the 240 panel and then uses a balanced power isolation transformer to generate the individual 120 volt circuits from the single 240 feed.

amps * volts = watts

240 volts * 30 amps = 7,200 watts (maximum input into the isolation transformer)

120 volts * 20 amps * 2 = 4,800 watts (maximum outputs 1 & 2)
120 volts * 10 amps = 1,200 watts (maximum output 3)

(4,800 + 1,200 watts) = 6,000 watts < 7,200 watts (Note: 3 * 120 volts * 20 amps = 7,200 watts, but Equi=Tech probably designed in a safety margin)

I would assume the 3 circuits derived from the 240 volt / 30 amp feed comes from the multiple secondary windings in the specific isolation transformer being used.

See Equi=Tech's spec page for more details.

I would assume the transformer being used would be something similar to the one pictured below, but with 1 primary input winding and 3 secondary output windings (as well as balanced power +/- 60 volts/120 volt differential on the secondary wirings).


Someone that knows more about transformers (especially 240 volt transformers) can correct me if my assumptions are incorrect.

Also: There is a 240volt/30amp breaker in the service panel and separate 120 volt 10 and 20 amp breakers in the Equi=Tech. From the calculations above, the breakers in the Equi=Tech would appear to trip before the breaker in the service panel.

Here is what a balanced output transformer would look like (the 240 volt versions would also incorporate 2:1 step-down windings):

Cleeds, I found this sheet about another vendor's combination step-down/isolation transformer. It confirms my assumptions above. It takes a single 240 volt input and outputs 5 * 20 amp 120 volt balanced power circuits (+/- 60 volts, 120 volt differential). It is twice the size of my Equi=Tech unit.




Here is a review of one of Equi=Tech's service panel units similar in size to the above competitor.

FWIW: Equi=Tech was instrumental in amending the National Electric Code (NEC) to include "Technical Power" in 1996 and 1999. That seems to be a substantial contribution to clean power technology.

My amp (dual mono) has two Shunyata Sigma HC power cords direct to the wall. The Sigmas perform a conditioning function by themselves while avoiding any current choking that sometimes occurs with line conditioner components.

My 601's are plugged into a P10 Power Plant which in turn is plugged into a Furutech GTX-D Rhodium receptacle on a 20-amp dedicated circuit.
