Hi there,

I ran some graphs in REW and it kept saying the levels are low. I am using a Turtle Beach ARM external sound card. I have set all volumes to max and it is still saying it is low. Can anyone advise me on where I am going wrong and what I need to do get the levels correct. It calibrated the soundcard fine.

cheers

It calibrated the soundcard fine.
By this, do you mean that the input and output levels on the VU meters were correct and easily attained without the input volumes set to max when using the loopback cable for the soundcard routine?

If that's the case then you need to look at the microphone, microphone cable or line-in adapter. You're using the same (right) channel that you used for loopback soundcard calibration, so you know there's nothing wrong with the card.

Bruce,

When I calibrated the sound card all I did was put a 3.5mm single cable and put one end in the line in of the sound card and the other end in the line out of the sound card. Does this work ok.

I then matched the levels with the volume on the soundcard.

Is this correct.

cheers

Yes, that's correct.

Once the soundcard cal file is done, you remove that 'stereo' cable and plug in adapters to the line-in and line-out that splits out the right and left channels of each. Then you connect the meter/mic up to the right channel line-in and the right channel line-out goes to your receiver. Did you do that?

Bruceuk,

I didn't use adapters. What I did was, I have two identical cables. One end has a single 3.5mm and the other end splits into 2 rca ends. I use one to connect the single end into the line in and then connect the other end to the spl meter. Then the other cable I connect the single end into the line out and then plug the other two into the receiver. Is that correct?

cheers

The single plug is mono. The line-in and line-out jacks are stereo. You require stereo plugs split to two RCA, so left is left and right is right.

Bruceuk,

Isn't a cable with a single rca on one end and two rca cables on the other end the same as using a y adapter to split the signal.

But we don't want to split the signal. We want to 'break it out' into its left and right channels. The line-in and line-out are stereo jacks - not mono.

Bruceuk,

I see, so I need to buy two y adapters and 3 single rca cables. One for the spl meter and the other two for the receiver for left and right.

Is this why my levels are low?

cheers
