You are able to configure the right channel of your soundcard for cue channel output. The on-air signal is mixed to mono and then fed through the left channel of your soundcard. The cue channel is also converted to mono, but fed through the right channel.
Note: When using this method the Save as Wave functionality still receives a full stereo signal.
Click on the Ots Labs Power Amplifier in the OtsTurntables window. This will open the Output Configuration dialog box.
Make sure that your main soundcard is selected in the "ON-AIR" output device and that Enabled option is selected.
Select the Right channel option in the Use on-air device for cue: options.
Close the Output configuration dialog box.
To test, play a file and click the Cue button on the Mixer. You should notice the cue channel output through the right channel.
Tip: You may notice the ON-AIR signal through the cue channel. For instructions on how to remove the "ON-AIR" signal from the cue channel click here.
