1. STATUS INDICATOR
   Below is a table of the LED blink codes and their corresponding description

2. +/- VOLUME:
   Toggle either button to vary the volume level. When the SUB+ is network-paired to another Player, the volume buttons act as a +/- dB trim in relation to the primary Player’s volume level. When the SUB+ is not network-paired to another Player, the volume buttons control the full volume range of the SUB+.

3. FUNCTION BUTTON :
   A) TOGGLE SUB ON/OFF: When the PULSE SUB+ is network-paired to another Player, pressing the Function Button once will toggle the Player’s Subwoofer ON/OFF switch in the BluOS App. With the switch set to ON, a crossover is engaged: the SUB+ will handle the low frequency while the paired Player will handle the higher frequency content, as dictated by the crossover level. With the switch set to OFF, the crossover is disengaged and the paired Player handles the full frequency range. The SUB+ will be silent in this case. Note that using this toggle does not unpair the SUB+ from a Player. Further, this function does not work when multiple SUB+ are paired to a Player.
   B) STANDBY: Press and hold the Function button for 5 seconds to place the SUB+ into Vacation Mode (0.5W Standby). In Vacation Mode, all network activity will cease and the subwoofer will not appear in the BluOS App. Press the Function button again to restore the SUB+ to Ready Mode.
   C) UPGRADE MODE: To manually place the SUB+ into Upgrade Mode, first disconnect it from electrical power. Wait a moment, then reconnect power. Press and hold the Function button until the LED turns green and then back to RED, then release. The LED will immediately turn Green and then back to Red. The SUB+ is now in Upgrade Mode. This is only necessary in specific cases with authorization from a Bluesound support representative.
   D) FACTORY RESET – more information on Factory Reset is available on page 9 of this manual.

4. MOUNTING FOOT: The PULSE SUB+ can be placed in several orientations, including (but not limited to) laying flat on its back or mounted to the wall. The back panel Mounting Foot (x4) provides the necessary cushion to help prevent unwanted vibrations when the SUB+ is laying on its back. The Mounting Foot is also the attachment point for wall mounting; the shaped groove in the Mounting Foot slides onto the rubber foot on the supplied wall mount bracket and uses gravity to lock it into place.

5. LOW/LINE LEVEL INPUT: For connecting the PULSE SUB+ via wire to another Bluesound Player that has a wired SUB OUT, or alternatively to a separate component preamplifier, integrated amplifier, or receiver, at line level.

6. SERVICE: Use the Service port in conjunction with USB (Type B Mini) to load firmware on the PULSE SUB+. This is not for consumer use. Only Authorized Bluesound Service personnel can access this USB port and Service control button.

7. AC MAINS INPUT: Select the AC power cord appropriate for your region (included). Before connecting the plug to the wall outlet, firmly connect the other end of the AC power cord to the PULSE SUB+ AC Mains input socket. Never force the plug into a wall outlet. An adaptor may be necessary for certain regions. Always disconnect the plug from the wall outlet first, before disconnecting the cable from the SUB+ AC Mains input socket.

8. USB (TYPE B): Use the Service port in conjunction with USB (Type B Mini) to load firmware on the PULSE SUB+. This is not for consumer use. Only Authorized Bluesound Service personnel can access this USB port and Service control button.

9. USB (TYPE A): Use the USB (Type A) port for manual software upgrades. This is only necessary in specific cases with authorization from the Bluesound Support Crew.

10. LAN PORT: The LAN port connection is used with an Ethernet cable (not provided) for network connection and control. This is an optional connection since the PULSE SUB+ can be connected to the network through Wi-Fi. If you are using wired Ethernet for the network, connect one end of the Ethernet cable to the SUB+ LAN port, and the other end directly to your router or switch.

11. MAGNETIC RUBBER FEET: When the PULSE SUB+ is placed in a standing position, use the supplied magnetic rubber feet (x2) to help prevent unwanted vibrations. The magnets are mounted inside the cabinet of the SUB+. Simply place the magnetic rubber feet near the required location and they will snap into place.

CHOOSE PLACEMENT

Room Acoustics
If you are critical about the low-frequency response, there’s quite a bit of useful experimentation you can do, especially in combination with the crossover, level, and phase controls of the PULSE SUB+.
Begin by considering the size of the listening room. The larger the volume of air a speaker must move, the more acoustic output is required to achieve the sound levels you want. In smaller rooms, sound attenuation tends to be offset by reinforcement from wall reflections. In larger spaces, sound has to travel to reach the reflecting surfaces and then to your ears, which means it has to be louder, to begin with.
After size, the most important aspect of a listening room is its shape. In any room, sound reflects off the walls, ceiling, and floor. If the distance between two opposite parallel surfaces is a simple fraction of the wavelength of a particular frequency, notes of that frequency will bounce back and forth in perfect phase—an effect called a standing wave or room mode. At some point in the room, this note will be reinforced substantially; at others, it will cancel out almost entirely. If the prime listening seat is placed at either of these locations, the note will be a horrible boom or virtually non-existent. Almost all rooms are susceptible to some standing waves at low frequencies, but careful positioning of the speakers and the listening seat can minimize the effects. The only way to find out what works best is by experimentation. The positioning of a bass speaker has almost no impact on imaging, so the PULSE SUB+ can be positioned almost anywhere.
Subwoofer Placement
The loudest bass output from a subwoofer comes from corner placement. The outward flaring of walls from a corner focuses low frequencies, giving them no place to go but toward the listener.
If you are seated in a null spot where sound from the PULSE SUB+ is canceled or diminished by out-of-phase reflections, you will have to move either the subwoofer or your
listening position until you get the desired bass. Adjusting the phase control 180 degrees may make a difference, especially if the null is a product of cancellations caused by
interaction with low frequencies from your main speaker(s). If the opposite is happening, where direct and reflected bass waves converge in phase and produce too strong a  peek at your listening position, you can change position or change your sub’s level control (or possibly the crossover frequency chosen).
The best method for positioning the PULSE SUB+ is to put it in your listening chair, then play music with lots of basses through the system (something with steady and obvious low frequencies). Move around the room and note where the bass sounds best; if you place the SUB+ in that location, you should get the same bass performance. This test only works if you have your ears at the same height as where the SUB+ will be, so you may have to get down low. A recommended starting point for placement would be in either of the front corners of the room.
Multiple Subwoofers—Why Two Subs Are Better Than One
Sometimes the listening room is not conducive to achieving satisfying amounts or quality of bass. There are rooms with troublesome dimensions, especially those that are more cubical. In such a case, two subwoofers placed carefully to work with each other are recommended to handle acoustical anomalies. This can also be applied when the problem is too much, or too uneven, bass. The overall system benefits from each subwoofer correcting the acoustic problems caused by the other. A very good starting point for positioning two subwoofers is to place one each in the center of opposing walls. Experimenting with positioning as previously described should be used for determining the location of the second subwoofer, except in this instance one is listening for the minimum amount of bass output.

CONNECT FOR SOUND

There are several ways to connect the PULSE SUB+ to your audio system.
Wireless Connection
The SUB+ is designed first and foremost as a wireless subwoofer solution to be used with other Bluesound Players. To use the SUB+ wirelessly, you need to connect it to your desired network. A simple App-based process will help you connect your SUB+ and pair it with another Bluesound Player.
Follow the steps in the Quick Setup Guide to get your SUB+ positioned and powered on. Open the BluOS App on your phone or tablet. In the right-hand Player Drawer, select Add A Player, and when prompted, select Add Subwoofer. Follow the guided wizard to add your SUB+ to the network via Wi-Fi and ensure it upgrades to the latest BluOS firmware. This can take a few minutes.
Once connected and updated, your SUB+ will show up as ‘Unpaired’ in the My Subwoofers section of the Player Drawer. The LED indicator on the SUB+ flashes long Blue and short Purple when it is on the network and ready to be paired. Select the Link/Pairing icon to open the Pairing wizard and select the Player you want to pair with your SUB+.
The PULSE SUB+ is now paired and ready to use. You can access advanced audio controls through the Audio Settings menu of its paired Player.

Wired Network Connection
To use the PULSE SUB+ wired to your network, you need to connect it via Ethernet to your router or switch. An ethernet cable is not included in the box.
Follow the steps in the Quick Setup Guide to get your SUB+ positioned and powered on. Open the BluOS App on your phone or tablet. In the right-hand Player Drawer, select Add A Player, and when prompted, select Add Subwoofer. Follow the guided wizard to add your SUB+ to the network and ensure it upgrades to the latest BluOS firmware.
Once connected and updated, your SUB+ will show up as ‘Unpaired’ in the My Subwoofers section of the Player Drawer. The LED indicator on the SUB+ flashes long Blue and short Purple when it is on the network and ready to be paired. Select the Link/Pairing icon to open the Pairing wizard and select the Player you want to pair with your SUB+.
The PULSE SUB+ is now paired and ready to use. You can access advanced audio controls through the Audio Settings menu of its paired Player.
Analog Low/Line Level Connection
The PULSE SUB+ has been designed to allow you to use an analog RCA cable to connect for sound, instead of sending audio over your network. If you are using your SUB+ with a receiver or integrated amplifier with preamplifier outputs, or if you are using a separate preamplifier, the best connection is from the Preamplifier Output of your electronics to the RCA Input of the SUB+.
The SUB+ will work with a simple low/line-level RCA. However, to pair with another Player and use the advanced audio controls via the BluOS App, you must connect it to the network via Ethernet or Wi-Fi, even if you will transmit audio to the SUB+ via RCA cable. Please see the previous Wireless and Wired connection information for more details on setting up your subwoofer via WiFi or Ethernet.

NEXT-LEVEL CALIBRATION

The settings in the PULSE SUB+ have been set to default levels in order to work well with your Bluesound Player in most listening environments. However, you may still require some adjustments to the settings based on placement and personal preference. The following procedure assumes your SUB+ is installed, connected to the network, and paired with a Player. If you are using the SUB+ as a non-networked, powered subwoofer, your ability to do next-level calibration will be limited.
With the Subwoofer audio settings menu open in the BluOS App, use these steps to fine-tune your subwoofer setup.

1. Set SUB+ volume to the lowest possible level. Set the crossover frequency to the lowest level, meaning the crossover slider is set all the way to the left side. Set any special audio features, bass, treble, or EQ controls on your paired Player to their nominal (midpoint or off) positions.
2. Play a familiar music source that includes substantial deep-bass content over an extended section.
3. Gradually turn up the volume of the SUB+ until you achieve a natural balance between the subwoofer’s deep-bass output and your speaker(s).
4. Gradually adjust the crossover up to reach the best mid-bass blend with your speaker(s). This will be the point at which the upper bass retains solid impact and fullness. Boom or muddiness is the result if the crossover is too high. A thin, ‘reedy’ quality to the mid-bass such as deep male voices (FM announcers; Darth Vader) is the result of the crossover being too low.
5. Toggle the Phase control between 0° and 180° several times, leaving it in the position that yields the fullest low to mid-bass output. You will now likely want to repeat steps 3 and 4 to check your subwoofer blend.

Cycling through steps 3 and 4 several times with slightly different settings of both the volume and crossover controls will help you get the most musical performance from your PULSE SUB+. The best combination is one that yields the most solid very-low bass sounds, without mid-bass boom or a gap in response between the SUB+ and another speaker (s).
The crossover and volume controls are interactive. Raising the latter while lowering the former can have the effect of extending deep-bass response somewhat, with a small sacrifice in overall loudness capability. In general, for well-recorded acoustic music, the lowest crossover setting that still yields a smooth transition between the subwoofer and the main speaker(s) is often the best choice and will promote deeper low-bass extension.
Note: The PULSE SUB+ volume control is not intended as a bass boost or daily volume control. It is designed as a set-and-forget adjustment, and not for day-to-day use.

TROUBLESHOOTING

a live AC outlet.
The PULSE SUB+ utilizes signal sensing auto on/off circuitry. If no signal is sent to the subwoofer, it will not power up. When using the subwoofer output of a receiver or processor, no signal may be immediately present in this output. The subwoofer will only power up when a bass signal appears at the subwoofer input.
If the wireless connection or low-level cable is poor or has been severed, the subwoofer may not make a sound.
Sounds distorted| Lower volume if the subwoofer begins to sound distorted to determine if playback at a lower level solves the problem. If a slight reduction in level solves the problem, then the subwoofer level was too high. If the distorted sound remains at a low level, the driver may be damaged.
Hum| Hum, that appears when using the PULSE SUB+’s low-level input(s) is usually caused by using an inferior, damaged, exceptionally long low-level cable or cables routed near high current wiring/appliances. Replace/shorten the low-level cable connecting the subwoofer to the source equipment (receiver or processor). Low-level cable runs of longer than 20 feet may require the use of a line driver (not available from Bluesound).
