How do I manage the Audio Settings on NODE? – The Bluesound Support Crew

You can modify the audio output of the Player by adjusting the audio settings in the BluOS Controller App.

To manage the audio output settings of the Player, perform the following steps:

In the BluOS Controller App, select the Player Drawer. The list of players connected to the BluOS Controller App is displayed.
Select the Player’s context menu (3 dots) and select Audio Settings to display the menu options.

Note: Upgrade the BluOS firmware of your Player to get the latest Audio Settings menu options available for your Player. The Audio Settings menu options vary depending on the model of the Player.

AUDIO SETTINGS	NODE X	NODE (N130)	NODE 2i	NODE 2	NODE (N100)	DESCRIPTION
Audio clock trim						Enable to reduce jitter and increase audio clock timing precision when using an external DAC. Note: Not all DACs can handle this. If audible clippings or dropouts occur, disable Audio Clock Trim to avoid BluOS's accuracy setting from interfering with the external DAC's firmware.
Bass						Adjust the Bass output levels of your Player.
Crossover						Adjust the crossover between 40Hz and 200Hz – by default, set to 80Hz. When the Subwoofer option is enabled, everything above the crossover is filtered out and sent to the RCA and Speaker Outputs. The Player sends anything below the set crossover out of the Subwoofer (SUBW) OUT.
MQA external DAC						Enable this option when you require an MQA certified external DAC to handle MQA unfolding rather than the BluOS Player. Note: To enable MQA external DAC, you should enable the Output level fixed, disable – Tone Controls and Replay-gain.
Output level fixed						Enable to fix the volume of the BluOS Player at the maximum level. It helps when you control volume using the external device connected to the BluOS Player instead of the BluOS Controller App.
Output mode						Select any of the following to configure the channel output on the BluOS Player: Left/Right – Outputs only the Left or Right audio channel. Mono – Outputs single-channel audio out. Stereo – Outputs both Left and Right audio channels.
Replay-gain						Select any of the following to configure consistent volume levels between tracks in the play queue: Track gain– To use the track gain value from the song's metadata to have the current track's volume be more consistent with other tracks. Album gain – To use the album gain value from the metadata to provide a consistent volume level between all audio tracks on a particular album. Smart gain– To allow the BluOS to automatically choose between track gain and album gain values to provide the best replay gain option for your current listening. BluOS uses the metadata of the selected audio track to configure consistent volume levels between tracks.
Reset All						Restore the audio settings of the selected Player or Listening Mode to default factory settings.
Subwoofer						Select any of the following to configure the Subwoofer setting: ON – Apply a high pass filter to the RCA and Speaker Out (where applicable) based on the crossover set. OFF – Send full range out of the RCA and Speaker Outs. Note that the SUBW OUT output will not be affected by this, nor will it set a filter on the digital outputs. When you pair a PULSE SUB+ with a BluOS player, selecting Subwoofer displays the PULSE SUB+ Audio Settings.
Tone Controls						Enable to adjust your Player's Treble and Bass output levels. Notes: When enabled, the total volume of your Player is reduced by 6dB to allow adjustment of the bass and treble outputs from -6dB to 6dB. Tone Controls for the PULSE models are by default enabled. Tone Controls is disabled and not displayed when MQA external DAC is enabled.
Treble						Adjust the treble output levels of your Player.
Volume limits						Set the upper and lower limit of volume controls in the BluOS Controller App. Modifying the upper or lower volume limits of the BluOS Player allows more fidelity when adjusting the volume.
