Connecting Power

There are two ways to connect a Sub to power: connecting to a power outlet or connecting to an L1 Pro32

with a SubMatch cable. The Power Input Cover prevents simultaneous connection of both power inputs. Only

one of the two power connections should be used at a time.

If connecting directly to a power outlet, slide the Power Input Cover to the left, concealing the SubMatch

Input. If connecting to an L1 Pro32 with a SubMatch cable, slide the Power Input Cover to the right,

concealing the Power Input.

WARNING: Do not alter, modify, or remove the sliding cover over the power input of the Sub1/Sub2.

There is uninsulated, dangerous voltage within the product enclosure that may present a risk of

electrical shock.

Connecting Directly to a Power Outlet

q w e

1. Plug the power cord into the Power Input.

2. Plug the other end of the power cord into a live electrical outlet.

Note: Do not power on the Sub until after you've connected your sources.

3. Press the Standby Button. The LED will illuminate white while the Sub is on.

qw e tr

L1 Pro32Sub1/Sub2

1. Plug the SubMatch cable into the SubMatch Input on a Sub1/Sub2.

2. Plug the other end of the SubMatch cable into the SubMatch Output of the L1 Pro32.

3. Plug the power cord into the Power Input on the L1 Pro32.

4. Plug the other end of the power cord into a live electrical outlet.

Note: Do not power on the L1 Pro or the Sub until after you've connected your sources. See the L1 Pro32

owner's guide at PRO.BOSE.COM for more information about connecting sources to an L1 Pro32.

5. Press the Standby Button on the L1 Pro32 then press the Standby Button on the Sub. The LEDs will

illuminate white while the L1 Pro and Sub are on.

Note: Press and hold the Standby Button for 10 seconds to reset the Sub to factory settings.

When using two Subs via SubMatch cable connection, ﬁrst turn on the Sub connected directly to the

L1Pro32, then turn on the second Sub.

AutoO/Low-power Standby

After four hours of no use, the Sub will enter AutoO/Low-power Standby mode to save power. To wake the

Sub from AutoO/Low-power Standby mode, press the Standby Button.

Note: Disable AutoO/Low-power Standby mode by pressing and holding the Phase/Pattern Button and Line

Output EQ button simultaneously for 10 seconds. Enable AutoO/Low-power Standby mode by repeating this

step. Disabling AutoO/Low-power Standby mode will result in higher energy usage when the Sub is not in

use.

Inputs and Outputs

Line Input

Analog input for connecting an L1 Pro or other line-level audio source. Compatible with XLR, TRS balanced,

and TS unbalanced cables. Use Line Input 1 (Left) and Line Input 2 (Right) together for stereo applications.

Line Output

Use an XLR cable to connect the line-level output to a loudspeaker. Use Line Output 1 (Left) and Line

Output2 (Right) together for stereo applications.

Settings

Phase/Pattern

Adjust the polarity of the Sub. Press the button to switch between positive

polarity (+) and inverted polarity (–). The corresponding LED will illuminate

white while selected. Choose the polarity that sounds best for your

application.

Cardioid Mode

Cardioid mode is for use with a stack of two identical Sub modules, which

allows for most of the sound energy to be focused in front of the Sub stack

while reducing the sound energy that is generated behind the Sub stack. Press and hold the button for four

seconds to select CARDIOID. The LED will illuminate white while selected. Press and hold again to switch

back to +. Cardioid mode should only be used in a stacked conﬁguration of two identical Sub modules, with

the top Sub facing the coverage area and the bottom Sub facing the non-coverage area. Set the Phase/

Pattern of the top Sub to +and the Phase/Pattern of the bottom Sub to CARDIOID. When adjusting the level

of the stacked subs in Cardioid mode, be sure that the Level Control is set to the same position on both Subs.

See the below diagrams for Sub stack orientation and coverage patterns.

Setup

Level

Adjust the level of audio output from the Sub. Begin with the Level Control set to a low setting and increase

the level until the Signal/Clip Indicator illuminates green. The Level Control does not aect the Line Outputs.

The 12 o’clock position is recommended when in use with an L1Pro32. If using two Subs with a single L1 Pro, it

is recommended that the Level Control is set to the same position on both Subs.

Line Input EQ

Change the EQ of both Line Inputs by pressing the Line Input EQ button until the

corresponding LED for your desired EQ illuminates white. Use L1 to apply an input

EQ optimized for L1 Pro products; use LPF to apply a low-pass ﬁlter to the inputs.

When a Sub is connected to an L1 Pro32 with a SubMatch cable, the Line Input EQ

will be ﬁxed to L1.

Line Output EQ

Change the EQ of both Line Outputs by pressing the Line Output EQ button

until the corresponding LED for your desired EQ illuminates white. Use FULL for

full frequency or HPF to apply a high-pass ﬁlter to the outputs.

Note: If using the Sub with an S1 Pro, press and hold the Line Output EQ button

for four seconds to enable an EQ speciﬁcally optimized for use with an S1 Pro.

The HPF LED will illuminate green. To deactivate the S1 Pro EQ, press and hold for

four seconds.

Sub1/Sub2 Orientation

WARNING: Do not place the equipment in an unstable location. The equipment could become unstable

leading to a hazardous condition, which could result in injury.

CAUTION: Do not stack more than two Subs together. Only stack two Subs of the same model.

For horizontal conﬁgurations, adjust the logo by rotating it.

For stacked conﬁgurations, the Sub includes four interlocking feet that will attach to another

Sub of the same model. When stacking Subs horizontally, always make sure the feet lock

together before connecting power and sources.

Using the Pole-mount Insert with an S1 Pro

WARNING: The pole-mount M20 threaded insert on the Sub1 and Sub2 is designed to support a pole

of up to 1.3 meters (51 inches) with a Bose S1 Pro mounted on the pole. Do not use the Sub1 or Sub2

with a pole exceeding 1.3 meters (51 inches) in height or a loudspeaker weight that exceeds 7.1

kilograms (15.7 pounds). Using a pole/loudspeaker combination that exceeds either of these limits or

creates an unstable mounting scenario may lead to a hazardous condition that could result in injury.

The Sub1/Sub2 includes a pole-mount M20 threaded insert. The insert is compatible with the Bose Sub1/Sub2

Adjustable Speaker Pole accessory, designed for use with the Bose S1 Pro system (for more information, see

the Adjustable Speaker Pole owner's guide at PRO.BOSE.COM).
