  Audio becomes distorted when hard panning channels

  Posted by Jay Duchin on September 19, 2006 at 10:33 am

  I’m trying to make a tape back up master of a program. I’m running a G5 with FCP Studio (FCP5), Sony DSR 20 that is well maintained.

  The program in question is about 9 minutes long. Narration on ch. 1&2, music and effects on 3&4. My goal is to hard pan narration to the left and hard pan m&e to the right. When I do this, 2 thing happen:
  – the narration channel becomes slightly distorted
  – I can faintly hear the narration on the opposite, right, music channel.
  – in addtion to the bleed, there are occasion, timeline repeatable, bug zapper-like distortion hits.

  I’ve tried a ton of things but nothing is working. Has anyone ever heard of this happening?

  If I keep everything center panned, it sounds great. All the levels are spot on. I thought it might be my equipment rack but I’m now monitoring directly off the DSR headphone jack with Sony V6 studio monitor headphones.

  I did a test with 1k tone an it creates a similar problem. Took 5 seconds of tone and copied it on the timeline 3x. 1st is left panned, 2nd is center, 3rd is right panned. When it’s panned, the frequency becomes slightly distorted and… wrong. The only correct sounding ton is the center panned version.

  Any thoughts group?

  You have some serious problems, here.

  For starters, in digital, a full pan to either channel should have zero “cross-talk” (bleed) to the opposite channel.

  I’m suspecting the deck at this point.

  You’v e done everything just right as far as your testing.

  But try the test again, only THIS time, disconnect the deck from the FW and, instead,
  hook the Mac/FCP to a DV CAMCORDER set in VTR mode.

  After re-starting FCP with the camcorder turned on and connected (to establish a good FW link), plug in the headphones to the camcorder and try your tests again.

  Then please post back.

  It IS my DSR 20!!!

  I checked it first directly off the Mac and it was fine. I then tried it through my back up camera (Sony PDX10)and it was fine also.

  Time to hit the Sony website. Hard to believe a firewire connection to a deck could still produce crosstalk and distotion.

  Anyone want to buy as DSR20?

  Thanks!

  Its likely not the FW section at all.
  Could be something in the analog audio section of the electronics.

  Look thru the set-up menu to make sure all the settings are “normal.”

  Try to “reset” the deck.
  Look for a reset button or setting in the menu.
  And/or unplug the AC power to the deck for at least 30 minutes.
