Topic: audio set up

[tiger jing]

hi PDVD,

I recently re design my theater room and re arrange my audio set up. put my turn table 10 meters away from the amplifier. audio out put cable is too short so i used a connector to connect it together including the positive wire for the TT. the first connector i used didnt work well coz there's loud humming sound. The 2nd one i used which is gold plated work fine at first but it produce an irritating tweet sound every time i turn the volume higher. Need suggestion please.... Thanks

sir

it is best you put your turntable near your amplifier. most hifi people would suggest shorter distance for interconnects sa turntable.

10 meters ( 30 feet ) might be too long for unbalanced wires/cables.

humble suggestion:
1) if you have separate preamp with balanced output and power amp(s) with balanced input, you may want to use balanced wires/cable. place the preamp near your turntable and other music playback source. as bro Simon said, shorter interconnect cables.

the amp may be good near the speakers.

2) if you have an integrated amp/avr, maybe place it near your turntable and other music playback source, then use longer heavier gauge speaker wires. again, in this arrangement, shorter interconnect cables.


btw, try to connect your phono ground wire to chassis of your phono amp or integrated amp/avr and see if humming will be significantly be lessen, if not eliminated.

here is a sample phono amp with ground connector (right lower part, below the psu jack)
