The Q-SYS NL-SB42 is a network PoE soundbar that delivers clear speech and music reproduction natively to Q-SYS. It features a two-way design that provides wide off-axis response, and is optimized to better handle program content (in addition to voice content). The Q-SYS NL-SB42 supports vertical or horizontal mounting and can be integrated into your space with a single Ethernet cable to reduce overall hardware footprint and lower system cost. As a native Q-SYS Product, you can take advantage of the drag-and-drop integration and simple control capabilities offered by Q-SYS.

You can perform either a short reset or long reset:

  • Use a Short Reset to restore connectivity to a device in the event that unintended network settings were specified in Q-SYS Peripheral Manager or the device is otherwise unreachable. A short reset will restore device IP settings back to Auto mode (DHCP) and delete all Static Routes. The configured hostname is retained.

  • Use a Long Reset to restore the device to factory condition. This is useful for deeper troubleshooting, or when preparing the device for decommissioning or transfer.

    CAUTION: A Long Reset clears all network settings (including hostname), disables 802.1x, deletes user-installed device certificates, deletes all logs, and clears the device password.

Note: To cancel the Short Reset, release the button before 10 seconds has elapsed.

Performing a Long Reset

  1. Press and hold the Reset Button until the Status LED (NL, NM Series) or Power LED (QIO Series) begins flashing blue rapidly – approximately 20 seconds.
