This issue may occur when the subwoofer is not enabled. The following players include a subwoofer (SUBW OUT) output port that provides RCA analog output to a powered subwoofer:
- NODE 2/2i
- POWERNODE Gen1/2/2i/2i (with HDMI)
- VAULT 2/2i
- PULSE SOUNDBAR Gen1/2i/+
To enable the subwoofer, perform the following steps:
- In the BluOS Controller App, select the Player Drawer . The players connected to the BluOS Controller App are listed.
- Select the required player’s context menu (3 dots) and select Audio Settings.
- Select the Subwoofer toggle button to enable the subwoofer.
All sound signals are transmitted through the main player’s analog outputs only.
A crossover is applied at 80Hz (default) transmitting sound above 80Hz through the left and right analog outputs, while the sound below 80Hz is transmitted through the subwoofer.
POWERNODE (Gen1 only) can be connected to Bluesound DUO (2.1 subwoofer and satellite speaker system). This specific tuning set is custom designed for the response of the Bluesound DUO Satellite speakers and powered subwoofer. The default settings to configure Bluesound DUO are as follows:
VOLUME = 5
CROSSOVER = 120
PHASE = 0°
POWER = AUTO
