Hi Folks;
If any of you have ever wondered what sort of wire to use in your HW speaker system then I'd like to recommend you read the information found in this link:
http://www.roger-russell.com/wire/wire.htm#thetruth
I stumbled on this page while seeking an answer for the large HW installation that will be going into the church I play for.
There's a table part way down the page that lists the maximum distance a given wire gauge (AWG) can be run. The concept is to keep the resistance of the wires to no more than 5% of the Nominal Resistance of the speaker. The author states that there's no audible difference between simple zip cord or lamp cord and fancy expensive audiophile speaker wires so long both wire types are of sufficient gauge to fall within the 5% rule.
Our HW instrument will most likely have around 70 audio channels. All of the speaker wires (up to 30ft. or 40ft. in length) will have to be routed through a fairly small aperture, so I am wondering if cross-talk and stray interferences are a big enough problem to require shielding?
Does a shielded wire cause the amplifiers to see a more capacitive load?
I remember a couple of posts here that stated twisted-pair (cancels capacitance) and equal length on all channels (minimizes voicing) are both desirable characteristics for speaker wires. Any comments, additional wisdom?
Thanks.
