CONNECT FOR SOUND
There are several ways to connect the PULSE SUB to your audio system.
Wireless Connection
The PULSE SUB is designed rst and foremost to be a wireless subwoofer solution for the Bluesound
PULSE SOUNDBAR 2i. To use the PULSE SUB wirelessly, there is a simple pairing process to connect it
directly with the PULSE SOUNDBAR 2i. Press and hold the Pairing Button on the rear panel of the PULSE
SUB for approximately 5 seconds, then release. The LED indicator on the front of the subwoofer will blink
GREEN, indicating the subwoofer is in pairing mode. At this point, press the pairing button within the BluOS
Controller App.
Once paired, the LED indicator will go SOLID GREEN to show that the pairing process was successful. After a
short duration, the LED will turn off. The wireless connection is still active at this point.
The BluOS Controller App contains Setup Guides that will guide you through the pairing process with a
PULSE SOUNDBAR 2i.
Low/Line Level
If you are using your PULSE SUB with a receiver or integrated amplier with preamplier outputs, or if you
are using a separate preamplier, the preferred connection is from the Preamplier Output of the electronics
to the Low Level Input of the subwoofer. Use a dual RCA audio cable. Additionally, you may need to use
Y-connectors at the Preamplier Output to also send signals to the Power Amplier/Main Input.
Connecting the Low/Line Level Outputs from the PULSE SUB back to the Power Amplier Inputs is an
important option. The Low/Line Level Inputs of the subwoofer are internally processed through an active
high pass lter (at 12dB/octave below 80Hz) to the Low/Line Level Outputs of the subwoofer. Connecting
the Low/Line Level Outputs from the subwoofer back to the Power Amplier Inputs delivers the processed
signal, with reduced low frequency content, to the main speaker(s). With less low frequency demands, the
main speaker(s) can play louder. Particularly with smaller and/or less efcient main speaker(s), relieving of
the demands of reproducing low frequencies will allow greater sound output and dynamic capabilities from
the system overall.
LFE Connection
Note: Not recommended for use with Bluesound players.
You can use a single RCA cable to connect the LFE/Subwoofer Output of your receiver, integrated amplier,
or preamplier to the LFE Input on the PULSE SUB.
Home Theatre receivers, integrated ampliers, surround sound processors, and preampliers usually have a
special Subwoofer Output to provide the optional Dolby Digital or DTS Low Frequency Effects (LFE) Channel
present on many movie and other programming sources. To reproduce these deep-bass effects (when they
are present), supplementing the bass information in the main channels, this output must be connected to the
subwoofer.
The LFE or Subwoofer Output is ltered by most receivers/processors. The PULSE SUB’s variable low pass
lter is bypassed when using the LFE input, so sources that do not lter the subwoofer output should be
connected to the PULSE SUB via a wireless or low/line level connection.
In 2-channel source material there is no information in the LFE channel. However, bass signal can be diverted
to the subwoofer by selecting the appropriate AV receiver/processor surround mode.
