Guitar and line cables in the recording room...

As I can read in the SAE site:

"Guitar Lines: It is advisable to incorporate guitar leads between rooms. This allows you to plug a guitar into a jack in the control room and pick it up in the studio and plug it into an amplifier. Guitarists often like to play in the control room, especially if you are using effects, so a cable between rooms saves having to run leads through doorways. I have seen ads for a product that has a battery powered amplifier in the cable that compensates for the high frequency loss experienced when running long unbalanced guitar leads."

Does multicores has jack inputs or I must add to it? this jack wire, will need a DI, don't it?

Guitar cables are "unbalanced" and if I remember has a different impeadance than mic cable.

Depending on your setup, you can either A: run an unbalanced guitar line; B: some people like to put the head in the CR and the amp in the other room, so you'll need a "speaker" type of cable to run the amplified signal to the cabinet. In which case, you don't want it running near your mic lines.

Guitar cables are Hi-Z or high impedance cables. All cables, but especially hi-Z cables, are going to lose high frequencies as the run gets longer. So to avoid as much of this as possible, you'll want to get the lowest capacitance cable you can find. Most folks would suggest not running this guitar type of cable for more than about 30'. And like Aaron said, they're unbalanced usually. Although it wouldn't hurt anything to make them balanced, just it would cost more and you'd probably never use the extra line and it'd just be shorted anyways.

Microphone cables are low impedance or Low-Z. These are always balanced runs and don't have nearly as bad a problem with capacitance. Due to this and the probability of line level being sent on them most of the time, you can normally run up to 500' with no problems. If you've got the money, I'd go for quad lines too.

If I do this way, I need a jack-jack speaker cable. This type of cable is usually so short to avoid noises... I think is not a good way.

what is quad lines??[/i]

Quad lines are instead of 2 lines (hot & common), you have 2 lines for hot and 2 lines for common (4 total). eg: Canare star quad cable.

Sorry I hadn't had time to post links, pix, etc. This is the busiest I've at the office in the 7 yrs I've worked here (and it sucks). The boss has got us all under the microscope, so my online time per day has been 10 minutes or less. And I'm heading to Atlanta tomorrow to help layout Dave's wiring for his console, so I'll be unavailable for a couple days.

Sure, likely story...

Have a good trip, and remember - no wild pussies...

I hear the single ratio of women to men is 6:1. Might get lucky.
