I’m using a Rose RS250 via analog output. In the software settings, the volume control is set to off, but I can still adjust the volume using the slider in the app. Why and how do I disable this?
The Software Volume Control function operates only for digital outputs.
Some USB DACs support UAC2 volume control, while others support HID volume control.
In this case, when you adjust the volume on the Rose device, the volume command is sent directly to the DAC to control its output level.
If your DAC does not support this feature, you can enable Software Volume Control in the USB DAC settings under I/O Settings, and then adjust the volume via the Rose app.
Caution 1: This function cannot be used in Native DSD or DSD over PCM mode. It only applies when the output is converted to DSD to PCM (up to DSD128) mode.
Caution 2: For digital output, MQA Stream is supported only when the volume is set to MAX. If the volume is lower than MAX, MQA Stream will not be supported.
If you’re using the RS250 through analog output and wish to lock or fix the volume, you need to configure it through the Pre-Out Level setting in the I/O menu rather than relying only on the software volume setting.
Here’s how you can do it:
- Go to Settings → I/O Settings → Pre-Out Level.
- Set the output level to a fixed value that matches the input sensitivity of your amplifier.
- Once configured, the RS250’s internal volume will remain fixed, and the app slider will no longer affect the analog output level.
This ensures that your analog output maintains a consistent level while your amplifier handles the volume control.
Thank you for the comprehensive explanation. When the volume control is active, the scale ends at 99. Is this the maximum value?
Yes, that’s correct. When the volume control is active, 99 is the maximum value on the scale. It represents the highest output level for the device’s volume adjustment.
