High Freqency = Low Volume from Mixer

Hi,

I'm not actually trying to record anything. I wanted to be able to hear both a PC and an xbox 360 at the same time through a pair of head phones. It seemed a mixer was in order.

I bought a Behringer Xenyx 502 for this purpose, mostly due to price and decent reviews. The sound at most of the frequency range is fine. The volume between the two devices is perfect, after a bit of tweaking. However, high frequency sounds are not really audible, at least from the PC (like a flute, or a shrill whistle).

I've tried messing with the eq's to boost gain at the high ranges, and it seems like the sound isn't really garbled, but I cannot boost the volume high enough by any means to compete with the rest of the frequency range. I'm wondering if the mixer simply can't handle sound at that range, or I'm overlooking something. I am no sound engineer.

The PC has a 3.5mm from an onboard sound card going to a 0.25in connector into the mic input on the 502. I have also tried using one of the other line ins, with similar results. The xbox 360 is using RCA connections into the RCA tape ins. I'm using the head phone out, a .25in to 3.5mm connector, to my head phones. I've also tried using the main out. The sound is the same going to a pair of speakers. Bypassing the mixer, and therefore straight to headphones/speakers, sounds perfect.

Any suggestions? Thanks.
 
First nail down the location of the problem. Switch it around. If you put the PC into the RCA tape in and the Xbox into the 1/4 inch channel, does the problem then move to the Xbox?

Try putting both of them into 1/4 channels. Does the problem still happen?
 
Fixed

OK! It appears that going from my stereo lineout on the PC to a mono input on the mixer was causing the loss of sound. I bought a 3.5mm to dual 1/4in cable which solved on my issues. Thanks for the help!
