Active or Passive DI box to XLR inputs on a McCormack DNA amp??
« on: 14 Dec 2016, 01:42 am »
Anyone run an active or passive DI box to their XLR inputs on a McCormack DNA amp ?
Would be interested to know how that impacted your sound

Due to ground loop issues, I am considering a Jensen unit - this one has 100dB CMMR - is my e28 hi-Z signals?

http://www.jensen-transformers.com/product/db-2mm/

Jensens site says it's good for a DVD line level output to balanced amps. I don't see that the e28 DAC would have higher output than a DVD player's line level outputs?

"Connect the line level output from your CD player or hi-fi using the convenient RCA jacks to feed the PA system at the far end of the room."

Jensen makes excellent stuff, though you can find good alternatives in the pro audio shops for a much cheaper...

Have you tried lifting the shield at the XLR input?

Hi - my dac is unbalanced RCA and I want to run into the XLR inputs.

Right now, unbal to unbal has hum.

Previously, I was running a balanced DAC and there was no hum
