Audacity Forum

Hi

I have just recorded a DJ mix using this interface with Audacity.

I have RCA leads from my mixer to the Input L and R on the Behringer. Then this is connected to my iMac via USB.

When listening back to the recording i get a faint high pitched whistle throughout ????????

Can anyone advise why ?

Are my connections correct ? Do I have to change settings in Audacity ?

Thanks in advance

Does it still whistle if you listen to the iMac headphone out with the UCA202 disconnected?
It's a home run between the UCA202 and the iMac, right? No hubs?
Does it whistle if you switch the UCA202 to Monitor and listen at the headphone connection during the recording? Or stop playing for a second and listen for it.

Yeah no hubs. Have tried everything but I'm still getting the faint high pitched whistle. Very frustrating.

The monitor switch on the UCA202 should be off right ?

The Line-Out and the Headphone Out have the same show. All Monitor does is provide a way of listening to Line-In and Line-Out at the same time as a mix. This would seem to be of limited usefulness, but it's required to do Overdubbing and Sound-On-Sound.

It's also handy if you're having troubles. Turn it on and listen to your system at the UCA202 headphone connection with no music. Does it whistle?

Just tried this. It does whistle when monitor switched to On but not if I switch monitor to off ?????????????

By the way my speakers are connected to mixer not the output on UCA202.

That means the mixer feed to the UCA202 is whistling.

Time to get specific. Which mixer? Where is the UCA202 feed coming from? Tape-Out? Can you get it from somewhere else, like temporarily jack into the mixer headphone feed?

Mixer is a Pioneer DJM250 http://www.google.co.uk/imgres?imgurl=h ... AQ&dur=359

I am connecting the UCA202 via the Master 2 inputs.

Actually, it's the Master-2 Outputs. The mixer has two sets of outputs. The broadcast balanced (3-pin XLR) and the home music RCAs.

Thank you for the complete information.

This is where I would be dragging out test equipment which you can't do.

Ummmmm.

Wait. How are the speakers connected to the mixer and do the speakers have a volume control? Model numbers?
