Setting Up

Before you begin

Your 301® Series IV Direct/Reflecting® speakersre-createa natural balance of reflected and direct sound energy for an open, spacious performance. They are designed at Bose® to bring youhigh-qualitylistening pleasure.

The Direct/Reflecting® tweeter inside each speaker creates a pattern of sound similar to what you experience at a live concert. In addition, the Stereo Targeting® tweeters help establish the natural balance of sound, for full enjoyment of stereo even when you move around the room. These distinct left and right speakers also feature tuned port enclosures that contribute to their deep,room-fillingbass. An advanced crossover design adds to the realism and clear definition of both musical instruments and voices.

Your 301 Series IV speakers are significantly different from conventional speakers, so be sure to read this owner’s guide. It will help you set up and use your speakers properly, for the greatest enjoyment.

Unpack the carton

Carefully unpack the carton and save all packing materials for possible future use. Check the carton contents (Figure 1).

If either speaker appears damaged, do not use them. Instead, repack both speakers in the original carton and notify your authorized Bose dealer immediately.

Note: Now is a good time to record the speaker serial numbers on page 2 of this guide and on your warranty card.

Select the locations for your 301® speakers

Bose® 301 speakers are designed to fit horizontally on a table or shelf (Figure 2). Be sure to choose a stable and level surface for each speaker.

Place the left and right speakers (marked on the back of each one) on the left and right sides of your room, as you face them. Exactly where you put them depends on the size and style of your room and where you think they sound best. Feel free to experiment to find a location that is both convenient and provides the sound you prefer.

Note: Because the grilles on the front of each speaker protect the drivers inside, we recommend that you do not remove the grilles.

Here are some basic guidelines:

Place the speakers 4 to 12 feet (1 to 4 m) apart.

Choose a stable and level surface for each speaker, and attach the rubber feet.

Leave at least 12 inches (30 cm) of space from the end of a speaker to the side wall.

Leave at least 18 inches (45 cm) from the speakers to the floor or ceiling.

Leave at least 24 inches (60 cm) from the speakers to any TV screens or monitors.

Keep the back of the speakers within 18 inches (45 cm) of the wall behind them.

Do not place the speakers exactly halfway between the floor and ceiling or any other sound-reflectinghard surface.

Do not put the speakers in a vertical position.

Note: Bose speaker stands or wall brackets can extend your placement options. See “Optional accessories” on page 10.

Setting Up

CAUTION:

301 speakers are designed specifically for placement on a stationary shelf, table, or stand. On smooth surfaces like marble, glass or highly polished wood, vibrations may cause the speakers to slide. So be sure to attach the selfadhesive rubber feet to the bottom surface of each speaker for added stability and protection. The feet go in the corners of the flat surface, inside the seam.

Do not use these speakers in a moving vehicle.

To mount the speakers on a wall, use only the Bose WB-3wall mounting bracket. Please follow the mounting instructions that come with these brackets. Improperly mounted speakers may fall, causing injury and damage.

Setting Up

Choose the cord

It is important to use the proper gauge (thickness) of speaker cord. Standard zip cord (2-conductor,18-gaugewire) works for most applications. You can find this wire at most electrical and hardware stores.

You will need thicker wire if your speakers will be more than 30 feet (9 m) from a receiver (or amplifier). Refer to the wire recommendations under “Technical information” on page 10, or contact your authorized Bose® dealer for more information.

Note: Before running speaker cord through a wall or under a floor, check your local building code requirements and safety regulations. You may want to contact an electrical installer for this information.

Prepare the cord

Speaker cord consists of two insulated wires. The insulation around one wire is marked (striped, collared, or ribbed). This marked wire is always positive (+). The plain wire is always negative (–).These wires correspond to the red (+) and black(–)terminals on the speakers and the receiver.

At the ends of each cord, strip approximately 12 inch (12 mm) of insulation from both wires. Twist the bare end of each wire so loose strands will not touch across terminals. Be sure to connect each wire to the proper terminal (positive to positive and negative to negative).

Note: It is sometimes difficult to distinguish wire markings. Inspect both wires carefully.

Make the connections

Just press the terminal tab on the back of each speaker to insert the appropriate wire (Figure 3).

1.Connect one speaker cord to your right speaker.

a.Attach the marked wire at one end to the red (+) terminal.

b.Attach the plain wire at that end to the black (–)terminal.

2.Connect the other end of the same cord to the RIGHT SPEAKER OUTPUT of your receiver.

a.Attach the marked wire to the red (+) terminal.

b.Attach the plain wire to the black (–)terminal.

3.Connect the second cord to the left speaker and LEFT SPEAKER OUTPUT. Follow the steps in 1 and 2 above.

CAUTION:

Never use broken or frayed wiring, which can result in electrical shock or damage.

CAUTION:

Before making any connections, turn off your receiver and unplug it from the AC power (mains) outlet. Not doing so may result in damage to your system.

Setting Up

Check the connections

Check to be sure all connections are made positive to positive (+ to +) and negative to negative (– to –)(Figure 4). Make sure that no loose strands of wire touch across terminals. Bridged wires can short circuit and damage the amplifier. Tighten any loose connections before you plug in the receiver and turn it on.

Test the speakers

To make sure your speakers operate correctly:

1.Place the speakers less than 6 inches (15 cm) apart, facing each other.

2.Turn on your receiver. Set the receiver to MONO (monophonic), if that is an option on your receiver.

3.Make sure that all special effects (such as surround sound) are turned off.

4.Set the balance control to normal (center position).

5.Play some deep bass passages of music through the speaker.

The sound should seem to come from a point between the two speakers. The bass should be full and natural. If it is not, one of the connections may be reversed, causing the speakers to play out of phase (refer to “Make the connections” on page 6).

To correct the problem, make sure all the wires are connected positive to positive (+ to +) and negative to negative (– to –).Then repeat steps 1 through 5 above tore-test

the speakers.
