Getting ready

Thank you for choosing a Bose® SL2 Wireless Surround Link. It provides a simple and convenient means to enjoy the surround sound from your LIFESTYLE® system or powered Acoustimass® system. The SL2 features a small radio frequency transmitter and receiver pair that delivers the left and right surround audio signals, complete with amplification, to surround speakers in the rear of your room. Running cable from the front to the back of the room is unnecessary.

Unpacking the carton
Carefully unpack the carton and save all packing materials, which provide the most secure way to transport the product. Check to be sure your system includes all of the parts shown (Figure 1). If any part appears damaged, do not attempt to use it. Notify Bose or your authorized Bose dealer immediately. For Bose contact information, refer to the address sheet included in the carton.

Setting the transmitter for your system
If your speakers are part of an Acoustimass® speaker system, you need to set the switch on the bottom of the SL2 transmitter to Other (Figure 2).

For use of a LIFESTYLE® system with the SL2 Wireless Surround Link, the current default switch setting is optimal. There is no need to change the setting. Important note: Running the ADAPTiQ® audio calibration system, which is provided with your LIFESTYLE® system, helps ensure the most accurate sound from your system. Be sure to use it after the SL2 is connected and your surround speakers are in the final position. Choosing positions for your SL2 transmitter and receiver Radio frequency transmissions make this product easy to place. It is seldom necessary to point the SL2 transmitter at its receiver. This allows you to hide both from view if you like. The SL2 transmitter, identified on the label, is also distinguished by a single input jack (see Figure 3 on page 6). The SL2 receiver, which is also labeled, has two output jacks.

  • Place the SL2 transmitter within 61/2 feet (2 meters) of the Acoustimass® module.
  • Make sure it is within reach of an AC (mains) outlet.
  • Place the SL2 receiver at the same end of the room as your surround speakers. It, too, should be within reach of an AC (mains) outlet.

Position the transmitter/receiver pair:

  • From 61/2 feet (2 meters) to 30 feet (9.2 meters) apart.
  • Where the sides are unobstructed to allow for ventilation.
  • Upright (neither upside down nor on a side) on the floor or other flat, stable surface.

Note : If you experience any problem with communications between the SL2 transmitter and receiver, positioning them within line of sight to each other may be helpful. For further suggestions on how to deal with such problems, refer to “Troubleshooting” on page 9.

Making the connections

Use the small power pack with the SL2 transmitter (Figure 3). The large power pack is for usewith the SL2 receiver

To adapt the surround speaker cable for Jewel Cube® speakers
Follow these steps before you connect the provided surround speaker cable to your Jewel Cube® speakers.

  • Loosen the screws on the Jewel Cube® speaker adapter so you can insert the two-wire ends into its terminals.
    • Insert the plain wire (–) into the plain terminal.
    • Insert the red-banded wire (+) into the red terminal.
  • Tighten the screws (Figure 6).

What the Status LEDs indicate

  • On the rear of the SL2 transmitter and receiver, the color of the Status LED indicates how each unit is functioning. With the power pack plugged in, the LED lights as follows:
  • Blinking green: when one unit is trying to link to the other.
  • Solid orange: in sleep mode for low power use when there is no audio signal to communicate.
  • Solid green: the receiver and transmitter are communicating with each other.
  • This green LED stays lit for several minutes after communications cease.
  • Blinking red: the SL2 receiver is too hot, or there is a problem with the surround speaker cable connection between the SL2 receiver and the speakers.
  • For information on how to deal with a blinking red LED, see “Troubleshooting” on page 9
