Really? If I had a choice I would cut my speaker cables to length. The speaker to power amp connection operates in the current domain. This is an extremely low impedance interface. The output impedance of most amplifiers is less than 0.1 ohms feeding a speaker and crossover system with...

While I agree the subwoofer cable doesn't have a lot of demands placed on it, I'm not a big fan of the F-to-RCA form of termination. The F connector has as its center pin the solid center conductor of the coax cable itself. This exposed wire can oxidize and usually does, producing an...

But then you'll still be stuck with the limitation of not being able to record and watch something else. Might as well get a non-HD PVR today and then add the HD version when it comes out. They have a great deal on now at Expressvu for PVR's with $150 off. (Actually you can get another...

Darren, If you have checked that the specs indicate the output level of your receiver don't match the input level of the pro amp then simply add a line amp as suggested. Why the hesitation to add the line amp? brucek

The point is that since the sub signal is already managed in timing and crossover by the receiver, you don't want the sub interfering by adding any more filtering. Some subs have a switch which bypasses its own internal crossover when selected. In lieu of this, you can accomplish the same...

jarek, Your receivers sub out would not be considered a classic "pre out" which infers stereo output and not bass managed. This type requires two cables to a sub with a stereo input and expects the sub to perform bass management. Your sub output is a combined mono bass managed signal with...

Since a satellite horns block amplifier receives its DC power from the receiver through the RG-6, you are not allowed to break the shield with one of these transformers....

Speaker cable length and phase differences? Don't worry too much about it. Electricity travels near the speed of light in a wire depending on its velocity factor, but that's not important here. This speed is approximated to about a nanosecond a foot. The accepted explanation would be that if you...

Very basically, ferrite cores are used to reduce EMI (electromagnetic interference). When a wire is passed through the core an inductor is created. If the core is wrapped with the wire, the inductance is increased. The more wraps, the higher the inductance. Inductive reactance (frequency...

Curt,

Curt, RG6 will certainly pass all the signals that you would ever want to send to a projector. Since it has a bandwidth capable for CATV it can easily pass all baseband video signals. The problem with RG6 isn't with its bandwidth capabilities, it's the fact that it's stiffness makes it a...

Sean, There are some points that you're confused about. Instead of trying to dissect everything you said, I'll just give you a general overview. It may help. A power amplifier has a low output impedance. It's not a perfect voltage source, but in relation to it's load (which is significantly...

Matt, You're right about the mess on the bench and that crosstalk is not a huge concern at this short distance. These are the standard tests to run to verify a cable passes the spec, so I ran them. There will be mutual inductance between any conductor that passes near another conductor and in...

John, Here are the results of the cable test I promised. I put the little explaination of each test above the results. The data really isn't that useful other than for cursory interest. The useful information is that each test passed the 10MhzCAT3 specifications. Of course, the cable was only...

Interesting article Chu. I can't argue with his math - don't know much about speaker design. Most solid state amplifiers possess an output impedance that is fairly constant (read linear) and very, very low over the entire audio spectrum and as such can almost be ignored in the damping...

John, yeah if I can find the time I'll post the results..kinda meaningless though.....and boring. Matt, yep, I agree. It was only for a little experiment. I just couldn't let that one foot challenge stand... :)

Kevin, Since your speaker cables are likely to be different lengths, I feel your plan of 'balanced' gauges has a few holes in it. Not that it would matter, but you would have to make the calculation of length combined with appropriate gauge to ensure the resistive load was matched all round...
