Hello forum!

I just got into E-Mu samplers, been into Kurzweils in the past but always desired an E4 as well. Just bought a E4Xt Ultra from a local film composer so its been taken care of, but probably used a lot.

My problem with it is,

If running unbalanced from its outputs it makes a buzzing and beeping and noise, sounds like a bad internal soundcard from a PC almost. If I run balanced into my mixer the beeping and buzzing goes away, all there is is standard thermal noise at low levels. The beeping and buzzing is so loud it is unusable without using balanced cables. The noise is not present on the headphone output.

I have removed and powered off all SCSI gear, noise is still there

The machine has no internal HD (looking to make or buy a internal HD cable for that)

Is this normal behavior? I this machine defective?

I have the means to run it balanced, I just find it odd that my K2000R is unbalanced with SCSI gear attached and is not noisy like this.


Thank you for your help.

dont know if this helps.. but i had a similar problem with an esi2000 a few years back. i had to take it to the dealer i bought it from and they had their electrician resolder the outputs... in my case it was only happening on the main outs.. have you tested the other outs w/ unbalanced and found the same problem? if its only one output, you should find an electrician and have them take a crack at it

thanks for the reply.

I have only used the main outs, I will test the other outs tonight. last night I finally got to write some music with it, sounds good, love the sstart feature for drum loops. It certainly is different than the K2000 series, especially in file management and memory management, that will take a lot to get used to.

If it is solder job I have a ex-EE friend that would do it for me I think. I can solder a cable but don't feel comfortable working on PCBs, plus I don't have a regulated iron.
