So far I have bought a -20 dB Attenuator Cable because I was told that soundboards can run hot.
A DUAL XLR FEMALE TO STEREO 1/8" MALE PLUG. 72 inches
STANDARD STEREO ADAPTER - DUAL RCA MALE TO 1/8" STEREO MALE - 36"
and 2 CBI RCA Female To 1/4-inch Male Connector
Is there anything else I would need? I was told that male xlr adapters were pointless to get. If I should get them though, lemme know and if possible give me a link to where I can buy them along with some details on what kind I need exactly. I just spent 300$ for a njb3 and these cables so I plan on getting my moneys worth out of them and since very few bands let you do soundboard I will branch out into stealth recording once I figure all this stuff out. Anyway, thanks for all your help everyone and if you have any more suggestions or advice lemme know.
