| damping factor Actually, what happens is when the amp sends a signal to the driver it energizes the voice coil and causes the cone to move. When the signal stops, the woofer cone keeps moving by inertia (the amplifier cannot stop the moving mass). This causes th... | |
| Hum issue - driving me more crazy Bringing the cable above the floor may be moving them away from fluorescent ballasts. Speaking of lights, do you have any low voltage LED or decorative lighting that feeds off a DC transformer? These introduce DC into the wiring that get into grou... | |
| Hum issue - driving me more crazy Try lifting the grounds on the amplifiers by using a two-prong adapter. You have the perfect setup for ground loops -- all equipment plugged in multiple outlets spaced far apart on the same circuit along with interconnects running the length of th... | |
| "The Heat Pipes are coming"... The Heat Pipes are Heat sinks are rated in degrees c per watt. This means that the amount of heat dissipated is constant and that as the outside air warms, the device, too, warms to maintain the difference. Not correct. The term degrees C per watt is the thermal res... | |
| "The Heat Pipes are coming"... The Heat Pipes are You are telling us that removing heat = better sound. I am telling you that lowering the thermostat removes heat faster, increasing the surface area of the equipment case removes heat faster and increasing the conductivity of the equipment case re... | |
| "The Heat Pipes are coming"... The Heat Pipes are Good Lord... another fundamental law of science that is altered when audio equipment is involved. Heat transfer depends on basically three things -- temperature differential, surface area and resistance (thermal conductivity). These hp's affect th... | |
| Power line question I don't think you will have a problem. My guess is that each amp will consume about 300 to 400 watts each, maximum. That means both amps and a preamp in the same outlet will have as much of a power draw as a desktop computer, monitor and printer. ... | |
| High-end amplifier clarification? To me, "High End" always preceded the word "Audio" and not a specific component. You could take one of those half million dollar amps, hide it behind the curtains, and hook it up to a pair of $200 speakers and feed it from a consumer CD player and... | |
| How can a 40 watt amp outshine a 140 watt amp A 40 watt amp can out perform a 140 watt amp in two ways. First, a watt is current into a resistance, and the resistance is the speaker. But the speaker resistance varies with frequency. As the resistance offered by the speaker drops, the amp has ... | |
| wireing multipal outlets. Four wall boxes each with two Hubbell duplex receptacles? Use 6-inch pigtails in each box. Each wire nut -- one for black one for white -- will have 4 wires. It's easier IMO to use pigtails in ganged boxes. Also, pigtails are a better job -- reduc... | |
| Audio Supports It has to do with the center of gravity and the distance to the support points. If you have a speaker with a square foot print with four points of support at the corners, the center of gravity is equidistant to any two points that you tilt against... | |
| AC Power - two circuits better than one? If this was me and rewiring is not an option, I would look into getting a power distribution center such as a PS Audio Premier and plugging into the one 20-A outlet and seeing if all my gear can be accommodated. It is always better, IMO, to limit ... | |
| Dedicated line Dave:If you want to do it right, here is the way it ought to be. First, isolated ground receptacles are a benefit only from reducing EMI and RMI and is well worth the extra copper, IMO. Second, if you are using a subpanel for your two dedicated ou... | |
| Dedicated line You cannot ground your receptacles to a separate ground rod. In fact, no grounded conductors can be connected to a grounding connection on the load side of the main service disconnect. That means that the neutral wires of your dedicated circuits c... | |
| 100v mono blocks in series on 200v w/o transformer The amplifiers may have a 110V to 220V jumper around the power supply transformer. A lot of manufacturers build in the ability to run their products all over the world. Take it to a technician or an authorized dealer. It may be a simple service to... |
