Samson Support

hi, where i can get the power supply or remote input for a samson mdr1688 mixer...please can you let me know where or how i can get it., thank you. here my cell# 631-388-8013

im having problems when the speaker is at about half volume a crackling noise coming straight from the tweeter. just wondering if there is a quick fix or it needs replacing.. thanks

My system used to have a brilliant sound quality and both antennas were on full signal but now only one antenna light is on and the sound receiver hardly receives any sound so now when i play it comes out the amp a little muffled and sounds like it is missing the kick it had to it previously but when i go straight into the amp with a jack it\'s crystal clear and none of my gain is missing or muffled at all, this has only happened recently, any suggestions?

Speaker wire checks out okay, fuse is okay (obviously there\'s still power) blue light is on, just no output - checked all inputs, nothing looks fried on the board on the inside - what next?
