By using the Audio Settings on your player you can adjust different aspects of your audio output. These settings can be found by going to Settings > Player > Audio. Depending on the model of BluOS player you are using, the settings available may vary.
With Tone Controls enabled you will be able to adjust the treble and bass output levels of your player. Enabling this setting will bring the total volume of your player down by 6dB to allow adjustment of the bass and treble outputs from -6dB to 6dB.
Disabled: Full analog signals are provided to the Analog outputs.
Enabled: A Crossover is applied at 80 Hz, sending sound above 80 Hz to the Left and Right Analog outputs, and sounds below 80 Hz to the sub-woofer Out.
If a PULSE SUB+ is paired, tapping this option will open the PULSE SUB+ Audio Settings submenu. Please see Adjusting Audio Settings - PULSE SUB+ for more details
The replay-gain option will use the metadata of the selected song to help provide more consistent volume levels between songs in your play queue. By selecting Track gain the BluOS app will use the Track gain value from the song's metadata to have this track's volume be more consistent with other tracks. Album gain will use the Album gain value from the metadata to provide a consistent volume level between all songs on a particular album.
The Smart gain option will allow the BluOS app to automatically choose between these 2 values to provide the best replay gain option for your current listening.
Output mode will allow you to adjust which channel your currently selected player will output. By selecting Left or Right your player will only output the Left or Right audio channel through all available channels. For example, 2 speakers connected to a Powernode 2i will both output the right channel audio while Right is selected as the Output mode. While Mono is selected your player will output single-channel audio out of all the available outputs.
Output level fixed:
By enabling output level fixed you will have your player remain at max volume at all times. This setting is useful when connecting to external equipment where you would like to control the volume outside of the BluOS app.
MQA external DAC:
If you are using an external DAC which is MQA certified with your BluOS device you can choose to have the external DAC handle MQA unfolding rather than your BluOS device. To enable this setting, you will need to have Output level fixed enabled as well.
Audio Clock Trim:
If using an external, Audio Clock Trim will reduce jitter and increase audio clock timing precessions. Not all DACs can handle this. If audible clipping or dropouts occur, disable Clock Trim to avoid BluOS's accuracy interfering with your DAC's own firmware.
By adjusting Volume limits you can set the high end and low end of your volume controls in the BluOS app. Reducing the upper or lower limits of your player's volume will also allow more fidelity when adjusting your volume in the BluOS app.
The Listening Mode settings provides 3 separate profiles for your player's audio settings. By adjusting settings within these listening modes you can create a listening profile for music, TV, and movies which you can select depending on what you are currently listening to.
Wide Mode can be enabled to help better fill the listening space your player is located in.
By enabling this setting the BluOS app will attempt to increase the volume of spoken dialog when listening to TV or movies.
With Late Night mode enabled the BluOS app will help normalize the volume output of your BluOS device to prevent large spikes in volume while playing.
Deep Bass will provide an additional boost to your player's bass output.
The Front Row setting will disable many other audio settings and provide a custom-tailored filter to provide audio similar to hearing your music live. For additional information, please see the article below.
This option will reset all your currently configured audio settings on the selected player.
