Pink noise source
« on: March 13, 2014, 01:25:04 pm »

What are y'all using for pink noise source?

As an installer, I often need to feed pink into various types of inputs (XLR mic or line level, 3.5mm stereo, dual RCAs, etc.), and phantom power is not always available.

I had a phone app that provided test signals, but that pink noise sounded compressed, and kept shutting off after a minute. And my phone is only good for 3.5 or RCA inputs.

I have 10 minutes of pink noise (from Bink's Audio Test CD) saved as a WAV file on my player.  I set it to loop.  I have built up 3.5mm to XLR, and even unbalanced will drive most systems adequately for testing & measurement.

Just ensure the phantom power is off...


I have something like this...

Much of what it is used for does not involve mixers, or at least none with phantom power.  I can drive our Crown I-Tech/VerTec rig with my player.   Great for a test as we remove the caster boards as it flies out.  This is particularly good when we're doing stacks and racks shows - if there is an obvious problem I want to find it before I hand the system over to the BE or client.

I also have a stereo recording, voice that says "Channel 1" on the left, alternating with "Channel 2" on the right.  I can chase lines with this and a Q-box.

Also, my 3.5mm/XLR cable has the audio connections on pins 2 & 3, so without pin 1 there is no phantom.  Player is plastic case, so I can set it on a mixer with global phantom (but I don't see many of those).  I also carry RCA and 1/4" cables for the player.

thanks for the clarification on the 3.5mm - XLR connection.
Good ideas for setup testing.
I like the L-R recording, too.
