  • LHi audio settings for system sounds

    Posted by Jason Brown on August 13, 2010 at 6:24 pm

    I have my Mac Pro system sounds pushing out of the LHi via XLR to my mixer…but there is a large disparity between the volume coming from FCP and if I use “quicklook” for an audio file in Finder. Adjusting the system volume doesn’t seem to change anything.

    Is anyone else experiencing this and have an idea/solution?

    Don’t run system sounds through your Kona? Simply run the headphone out in to your mixer as well.

    It’s not balanced and I get noise in the connection

    You can install a hum remover or turn down the gain of your inputs. I only get hum from computer sounds if the output of my mixer is absolutely cranked to the point of causing hearing loss or speaker damage. I have my computer output up to full minus one tick box, then control all relative volume through mixer pots.

    Here’s an example of a hum box, I am sure there’s better or cheaper.

    Jeremy,

    Its less of a hum and more electronic interference. I’ve tried to isolate the cable run as much as I can but there are power cords and other cables running all around.

    Do u think a hum eliminator would remove other “interference”type sounds?

    I’m not hearing what you’re hearing, but potentially, yes.

    Hi Jason,

    I assume you mean a traditional mixer with buses, sends and then output to a set of monitors/speakers.

    Do you have an audio interface, like one from MOTU or Presonus or the like? Sounds like you would be a candidate for one.

    Audio interfaces generally run out of a firewire port, a few run out of a PCI slot. Most audio interfaces have balanced ins and outs as well as phantom powered mic preamps. Given you are using a mixer almost all in that situation would be running with an audio interface and possibly ditching the mixer as the audio interface can serve as a mixer as well in many instances.
