I just got an RS151. I have connected a Technics SL-G700 Player to the digital inputs. The output volume is very very low. I tried the coax and the USB inputs into the rs151. If I connect the analog outputs of the sl-g700 it works fine but not any of the digital.
This only happens with the rs151. It works fine when I connect to others DACs.
Is there a setting on the RS151 that I’m missing?
I’m not using the RS151 as preamplifier. I’m using it as DAC only.
Thanks
Volume control (pre-amp function) is also available through the digital outputs (coaxial/optical).
On the RS151, go to Input/Output Settings, then click the small gear icon in the Output section. There you will find the Software Volume Control option.
Please enable this feature.
Below is an explanation of Software Volume Control:
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 transmitted to the DAC to control its volume. If the DAC does not support this feature, you can enable Software Volume Control in the USB DAC settings within the I/O Settings menu, and then adjust the volume through the Rose App.
Caution 1. Software Volume Control cannot be used in Native DSD or DSD over PCM mode. It is applied only after switching to DSD-to-PCM mode (up to DSD128).
Caution 2. For digital output, MQA Stream is supported only when the volume is set to MAX. If the volume is below MAX, MQA Stream is not supported.
