Blu Jeans LC1 picking too much noise..

post #1 of 7
Thread Starter 

Hi

I use Blue Jeans RCA cable LC1, to connect my EMU1212M to amplifier with a TRS to RCA adapter,

the cable is great and good quality but when I raise the volume it starts to make a lot of noise especially highs, even picking up mouse movement,

this happens at very loud volume which I normally don`t use, but recently I`m using my integrated as power amplifier to drive my front channels, using the Receiver Pre out, so I have to use a lot of volume on the integrated,

the strange thing, this doesn`t happen with cheap RCA cable,

Is LC1 too sensitive? or perhaps their shielding is just marketing?

The Blue Jeans Cable, LC-1 analog RCA interconnect is one of the very quietest cables that you can buy.  So either you are now hearing sounds that poorer cables covered up or you have a technical problem in your system.

 

The LC-1 has excellent shielding.

All RCA interconnects have the same sensitivity.

The LC-1 is up to 25dB quieter than some cables. 

Maybe you are turning the volume up higher than before.

I`m using the integrated as a power amplifier, connected to receiver Pre out, so the volume is near the max level, maybe the TRS to Rca adaptor is causing the LC1 to pick Pc noise..

how cheap? the BJ LC1 is a cheap cable.

 

I doubt the issue is the cable itself.

You may want to read this article since you're making a balanced - unbalanced connection:

Thanks,

It seems I have a TS not TRS adapter, anyway probably I`ll use another pair of speakers with the receiver,

I never had problems with the EMU, and at normal volumes is fantastic..

Some  some balanced output stages are not what the appear to be, strange things can happen when mixing balanced and unbalanced interconnect systems.

Some writers that have papers on the subject: Bill Whitlock w/Rod Elliott, Doug Self and Mike Rivers.
