Using new hardware can be complicated at first.
Several things:
- Your output level knob in the Steinberg control panel should be at -0dB for all channels.
- Your mutes in the control panel look correct and should be activated for all channels.
- You are using the first channel in the Steinberg, but the second channel in Audiolense. You need to use Channel 0 in Audiolense.
- Set the output level in the Audiolense measurement window to -20 dB.
- I would recommend not using a non-standard output setting. Use channel 0 for Left, channel 1 for right, and channel 3 for subwoofer. This will then work properly with JRiver set to 5.1 output. Otherwise you will inadvertently end up switching left and right channels. If your amplifiers aren't connected properly, then reconnect them to the proper outputs. Use Check Speaker Connections in the Audiolense measurement window to make sure they are correct before measuring.
- REW should be closed or it will tie up the ASIO channels (if using ASIO in REW)
When using the UR824 for playback, I set all UR824 control panel outputs to DAW Out 1/2, DAW Out 2/3, etc. Then in JRiver I set the channel offset to 10 in the Audio Device > Device Settings. This makes sure that any UR824 mixer functions are bypassed. If you look at the block diagram on page 30 of the UR824 manual, you can see that the channels are as follows:
1-8: Mix Outputs (ASIO channels 0-7)
11-26: DAW Outputs (ASIO channels 10-25)
Since JRiver is the DAW (Digital Audio Workstation), you can set the offset to 10 when using DAW Out 1/2.
For measuring with Audiolense, it is still best to use Mix 1 L/R, Mix 2 L/R, etc.
Extra Credit:
The Steinberg is unique in that you can use the analog outputs for one zone and the headphone outputs for additional zones using the following:
Analog Outputs Offset = 10
Phones1 Output Offset = 0, Mix 1
Phones2 Output Offset = 2, Mix 2
Somewhere in the UR824 control panel you need to assign the Phones to Mix 1 or Mix 2. This lets you use the headphones without the sound going through the rest of your sytem.
