Setting Up

Acoustimass® module

Follow these guidelines to select a location for the Acoustimass module.

Note: To avoid interference with the TV picture, place the Acoustimass module at least 18 inches (45 cm) from the TV.

1.Place the Acoustimass module along the same wall or close to the same end of the room as the Jewel Cube® speakers. See the example in Figure 2.

2.Select a convenient location – under a table, behind a sofa. Do not allow furniture or drapes to block the ventilation openings of the module.

3.Place the Acoustimass module within reach of the audio input cable, speaker cables, and an AC power (mains) outlet.

4.Select a position for the Acoustimass module (Figure 3). For proper ventilation, place it on the long edge, with the connectors facing the floor. An alternate position is on its largest side, with the bass and treble controls facing up. Do not place the module on either end, as shown by the last two views in Figure 3.

5.Once you have selected a position for the module, place the four self-adhesive rubber feet near the corners of the bottom surface. The rubber feet provide increased stability and protection from scratches.

6.Aim the port (the round opening) into the room or along the wall to avoid blocking the port or creating too much bass.

7.For best bass performance, do not place the port at equal distances from any two walls or from a wall and the ceiling.

CAUTION: Do not cover the ventilation openings of the Acoustimass module. The slots on the end provide ventilation for the built-in electr onic circuitry, and should not be blocked.

CAUTION: The magnetic field from the Acoustimass module is not an immediate risk to your video tapes, audio tapes, and other magnetic media. However, you should not store tapes directly on or near the Acoustimass module.

Multi-room interface

Select a location for the multi-room interface. It may be placed out of sight, if you like.

1.Place the multi-room interface within 30 feet (9.1 m) of the Acoustimass module (the length of the audio input cable).

2.Place the multi-room interface close enough to the sound sources (TV, VCR, DVD, etc.) to allow for cable length. If you need additional audio and/or video cables to connect all of your components, see your dealer or call Bose® Customer Service.

CD changer

Select a convenient location for the CD changer.

1.Place the CD changer on a level surface. Allow enough room to lift the door.

2.Place the CD changer close enough to the multi-room interface to allow for a cable length of 6 feet (2 m).

40 specifications

The Bose 40 is an exceptional headphone model that offers an immersive audio experience, catering to audiophiles and casual listeners alike. Known for its remarkable sound quality, the Bose 40 incorporates advanced engineering and innovative technologies to deliver rich, balanced audio.

One of its standout features is the Active Noise Cancelling (ANC) technology. This system uses microphones inside and outside the ear cups to detect ambient noise, effectively cancelling it out for a serene listening environment. Whether you are commuting, traveling, or simply enjoying music at home, the ANC capability ensures you remain undisturbed by outside distractions.

The Bose 40 headphones also feature a proprietary TriPort Acoustic headphone structure, which enhances low-frequency performance without compromising mids or highs. This design ensures that users enjoy a full spectrum of sound, making every listening session a pleasure. The combination of dynamic drivers and a precise acoustic port embedded within the ear cups results in a sound that is both powerful and precise.

Comfort is a critical aspect of the Bose 40 design. The ear cups are crafted from soft materials that provide a snug fit, allowing for extended listening without discomfort. Additionally, the headband is carefully designed with cushioning, making these headphones suitable for prolonged use whether for work or leisure.

With Bluetooth connectivity, the Bose 40 headphones support seamless pairing with a wide array of devices, from smartphones to tablets and laptops. The headphone comes equipped with voice assistant integration, allowing quick access to Siri, Google Assistant, or Alexa. Users also appreciate the intuitive touch controls located on the ear cups, making it easy to play, pause, or skip tracks without needing to retrieve devices.

Battery life is another crucial feature, with the Bose 40 offering up to 20 hours of playback on a single charge. Rapid charging capabilities ensure that users can enjoy up to 3.5 hours of playtime with just a 15-minute charge, making it an excellent companion for on-the-go lifestyles.

In terms of build quality, the Bose 40 is sturdy yet lightweight, making it easy to carry around. The foldable design is perfect for travel, fitting neatly into protective carrying cases.

All these features come together to make the Bose 40 a leading choice in the headphone market, appealing to listeners who seek top-tier audio quality combined with comfort, modern technology, and longevity.
