    Which Cable & Audio Connector are Better?

    Hi to All!!

    I bought Peavey FX24 Mixer for our church & I want to know what cable (balanced or unbalanced) & connector is advisable for instruments like guitar, keyboard, etc.?

    Which one is better for Mixer to musical instruments connection? Both end 1/4 jack connector (LINE from Mixer to instrument), or XLR (mixer) - 1/4 Jack (instrument)?

    Sorry guys, just a newbie...


    God bless..

    Bless you for your service! and welcome to the forum.

    Probably the best way is to go balanced inputs all the way. Keyboards usually have balanced outputs, so a direct connection is no problem. This is usually a 1/4 trs (tip-ring-sleeve) plug.

    For unbalanced instruments like guitars I suggest a direct box. This little gadget converts the unbalanced signal to balanced, so you can take advantage of the noise cancelling capabilities of a balanced system. Use an unbalanced cable from guitar to box (1/4 tip-sleeve) then a balanced cable from box to board (xlr).

    Hope this helps. Let us know what else ya need!

    Rule of thumb: If it can be balanced, make it so.

    Balanced signals are the way to go.

    Direct boxes, etc... to balance instrument lines, and using TRS cables for other 1/4" connections that are balanced.

    But is it OK to use a balanced cable directed from board/mixer (XLR) to the guitars & keyboard using a Mono Jack (1/4"TS)?

    Or a balanced cable using both end 1/4 Tip-Sleeve (Mono) from Mixer (LINE) to instruments?


    A BIG THANKS to you Sir!!!

    No to both questions. Use direct boxes. Don't try to plug unbalanced stuff (high impedance or Z, 10,000 ohms, 1/4" ts) into balanced (low Z, 300 ohms, xlr or 1/4"trs) inputs.

    Guitars are hi z, and do not have enough strength to drive a line input correctly. Cool?

    General rule: if it's high impedance unbalanced, it isn't meant to go more than, say, ten feet. Long unbalanced lines, especially high impedance, invite trouble.

    If you must feed a balanced output into an unbalanced input, you need a specially wired cable. You can find out about that by searching this forum, but the safe way to go is with a direct box, which also gives you a way to eliminate ground loop hum.

    Electric guitars, as a rule, should only be plugged into guitar amps. The amps do a lot of tonal coloring, without which the raw guitar signal sounds lifeless. Then take a direct box to patch the amp's output into the board, or use a high quality mic in front of the speaker - the speaker itself is often a large part of the characteristic sound you want.

    If it's balanced, leave it so.
    Balanced is the only way to go!...

    There's a way-old song (1914) called "abba dabba honeymoon." Maybe crazyaphz could do one called "abu dhabi honeymoon."

    Let's see, a balanced symphony would be one by Haydn. I wonder what an unbalanced symphony would be. Oh yeah, one by Schumann. (He died in an insane asylum, you know.)

    Okay, this is getting out of hand. I'll stop now.
