Connecting the speakers to the receiver

Checking the speaker connections

Make sure the terminal knurled nut is tightened down firmly. Any gap between the wire and terminal can cause heat build up. Check to be sure the wires are connected positive to positive (+ to +) and negative to negative (- to -). Make sure no loose strands of wire touch across terminals, which can cause short circuits.

Equalizer Connections

There are two options for connecting the equalizer. Your choice depends on the type of receiver you own and whether you plan to use the system primarily for stereo or for home theater enjoyment.

Stereo/non-home theater use

(tape monitor connections)

The Bose® 901® active equalizer connects directly to your receiver through the tape monitor connection. If your receiver has more than one tape connection, use the second one (TAPE 2). To connect a tape deck, use the additional set of inputs and outputs located on the back of the 901 active equalizer marked TAPE RECORDER CONNECTIONS.

The TAPE MONITOR switch on the front of the receiver lets you switch the equalizer in and out of the signal path. This is important when you want to play conventional, non-equalized speakers or headphones attached to your receiver. See Using other equipment on page 13.

Note: If your receiver is designed for home theater use, it may not have a Tape Monitor switch. If not, you must use a PRE AMP OUT/MAIN AMP IN connection. This may also be called the ADAPTER or SIGNAL PROCESSOR connection. Refer to “Home theater use (PRE AMP OUT/MAIN AMP IN)” on page 10 for instructions on how to connect for home theater use.

1.Disconnect any external tape deck or signal processor connected to the tape monitor connection.

2.Use the twin cable assemblies (with two connectors at each end) that are supplied with the equalizer. Use the red connector for the right (R) channel connections and the other connector for the left (L) channel connections.

901 specifications

The Bose 901 speaker system, first introduced in 1968, has become an iconic piece of audio equipment renowned for its unique design and innovative sound technology. Renowned for its ability to deliver an immersive listening experience, the Bose 901 stands out in the world of high-fidelity audio.

One of the most notable features of the Bose 901 is its Direct/Reflecting speaker technology. This system utilizes nine drivers per speaker, of which eight are angled to reflect sound off walls and other surfaces in the listening environment. This design allows the speakers to create a more natural and spacious soundstage, replicating the listening experience found in live performances. The additional driver faces forward to provide direct sound, ensuring that both reflected and direct sound are delivered in harmony.

The Bose 901 is also equipped with an equalization system that enhances its performance. Each speaker comes with an equalizer specifically designed to tailor the sound output to achieve the best possible audio quality. This equalizer compensates for the natural deficiencies in speaker performance at various frequencies, resulting in a well-balanced sound profile. The equalizer can be adjusted to accommodate different listening environments, allowing users to optimize sound output based on room size and shape.

Another defining characteristic of the Bose 901 is its sleek design. The speakers feature a low-profile cabinet that fits seamlessly into various home decors. The compact yet robust construction allows for various placement options, whether mounted on stands or against a wall. This versatility ensures that users can easily incorporate the speakers into their living spaces without compromising on aesthetic or audio performance.

Durability and build quality are also significant aspects of the Bose 901 design. Historically, the materials used in construction have ensured longevity, contributing to the speaker's reputation for reliability. The fabric grille protects the drivers from damage while contributing to the clean, unobtrusive appearance.

In summary, the Bose 901 is a speaker system that marries innovative technology with thoughtful design. With its Direct/Reflecting speaker technology, unique equalization system, and elegant aesthetics, the Bose 901 has cemented its status as a revered choice for audiophiles seeking an exceptional listening experience. Whether enjoyed in a dedicated home theater or as part of an everyday audio setup, the Bose 901 continues to deliver sound that resonates with music lovers around the world.
