Multiple Connection Methods for SUB 10/ SUB 12 🔥🔥🔥🔥

SUB 10/SUB 12 supports five signal input methods and automatically selects the active signal based on the priority of each input. When multiple signal sources are connected, a higher-priority signal will automatically override a lower-priority signal. For most applications, we recommend using Wireless Input (Wireless Subwoofer Adapter) or Line Level (RCA line-level input), as these are the two most commonly used connection methods. To use a specific input method, connect the corresponding signal source to the appropriate input port on the rear panel.

Note: For optimal performance and to avoid unexpected signal switching, we recommend connecting only one signal source at a time during normal use.

Signal Priority: Wireless Input > Line Level > Balanced (XLR) > Speaker Level > Auracast 

 
 
Wireless Input
  1. Connect the wireless dongle to the receiver/peramp's audio output port using the 3.5 mm-to-RCA cable, and then connect the wireless dongle's USB-A plug to a 5 V/500 mA power output on the receiver/peramp.
  2. Press and hold the subwoofer's PAIR button for 3s to enter pairing mode (white indicator flashes rapidly). At the same time, press and hold the wireless dongle's PAIR button for 5s to enter pairing mode.
  3. Once pairing is successful, the indicator lights on both the wireless dongle and subwoofer will remain solid.

Note: The wireless dongle and SUB 10/SUB 12 are pre-paired at the factory and will automatically connect when powered on for the first time. If re-pairing is required, press and hold the wireless dongle's PAIR button for 8s to clear the existing pairing record, then repeat the pairing procedure above.
 
One wireless dongle supports pairing with up to two subwoofers simultaneously, making it suitable for dual-subwoofer setups in larger spaces. To pair a second subwoofer, press and hold the wireless dongle's PAIR button for 5s until the indicator flashes rapidly. Then, press and hold the PAIR button on the second subwoofer for 5 seconds.

Line Level
  1. Use the included 3.5 m RCA cable to connect the SUB 10/ SUB 12's Line IN (L/R) ports.
  2. Connect the other end to the Sub Out / LFE (or Pre‑Out L/R) output of the AV receiver/preamplifier.
  3. On the AV receiver/preamplifier, enable Subwoofer Output or Subwoofer On in the audio settings. The volume and crossover frequency are controlled by the AV receiver/preamplifier.

 
Balanced / XLR
  1. Use XLR balanced cables (not included) to connect the SUB 10/ SUB 12's Balanced Input (R/L) ports.
  2. Connect the other ends of the XLR cables to the source device's XLR L/R outputs.
  3. If needed, connect a second powered speaker or studio monitor to the SUB 10's Balanced Output (R/L) ports. The balanced signal will be passed through to the connected device.

Speaker Level
  1. Use speaker cables to connect the amplifier's Speaker Out terminals to the SUB 10/ SUB 12's Speaker Level In (R/L) terminals. Make sure the + and − polarities are correctly matched.
  2. Connect the SUB 10/ SUB 12's Speaker Level Out (R/L) terminals to the corresponding terminals on the main speakers.
Note: Make sure all binding posts are securely tightened to prevent poor contact or unwanted noise.
Auracast
  1. Set the main device (TX) to Auracast broadcast mode.
  2. Double‑press the subwoofer rear‑panel PAIR button (interval < 1 second) to enter RX receiving mode; the PAIR indicator flashes purple rapidly.
  3. Upon successful signal reception, the PAIR indicator stays solid purple.
