Need help with GL2400 channel line input
« on: October 07, 2010, 06:21:31 PM »

I've run into a problem on my GL2400/24: on every channel I've tried, the mic input works fine, but the line input will not pass signal.  Double checked that I wasn't using the insert or the direct out jack by mistake, pad's not engaged, channel isn't muted, channel gain is up, nothing audible or visible on the meter with PFL.  Tried the source and cable in another mixer and that's not the problem.  Any ideas on what the problem might be?

You need to engage the Line/pad switch when using the line inputs on individual channels.

Yeah, I've had a time or two where a button has caused me grief.

The most memorable was during a guest speaker's presentation while I was at my university.  He had this sibilance that I tried to tame with the EQ, but every few minutes I would notice it had resurfaced.  So, I got another audio guy to try his ear at it, and the same thing happened - we kept noticing it coming back after a few minutes of not focusing on that specific frequency range.

We finally realized that the channel strip EQ was bypassed and that we were fooling ourselves into believing the problem was being fixed, when in actuality, our EQ tweaks hadn't changed it one bit.  It reminded me of the "placebo buttons" on the mixer - you know, the extra channels with controls that you turn when parents want their kid's un-mic'd, un-DI'd guitar tone changed mid-song?

Yeah that feature had me scratching my head once too! Tried to route a FX processor to a unused channel. Laughing

I think that anyone who has ever had that dilemma knew from the thread title exactly what the answer was going to be...it's one of those "Oh, I've done that, too" things.
