Using Your 901® Series VI Speaker System

Playing your speakers

Always use the 901® active equalizer when playing your 901 speakers. How you set the equalizer depends on how it is connected to your receiver.

When connected to TAPE MONITOR

Press your receiver TAPE MONITOR button to the IN or MONITOR position. This switches the equalizer into the system. Check periodically to be sure the TAPE MONITOR is engaged. On some receivers the button may be labeled RECORD SELECT or RECORD OUT.

To play a tape deck connected to the equalizer, press the MONITOR button on the equalizer

IN (TAPE, position 2).

Return the MONITOR button to OUT (SOURCE, position 1) to listen to components other than the tape deck (CD player, radio, etc.).

CAUTION: Do not use the active equalizer with conventional, non-equalized speakers or headphones. This can produce unnatural sound, and can even damage some non-901 speakers. Before you play any non-901 speakers, be sure the receiver TAPE MONITOR button is OFF (OUT or NORMAL).

You can play a tape deck through conventional, non-equalized speakers, even if your receiver has only one tape monitor connection. Follow these steps to do this:

1.Connect the tape deck outputs to the AUX input jack on your receiver.

2.Leave the inputs of the tape deck connected to the TAPE OUTPUT jacks on the 901 active equalizer.

3.Press the receiver TAPE MONITOR to OFF (OUT or NORMAL). This allows you to record disc and radio sources. You may also play any program source (including tape) with or without 901 equalization.

Note: This arrangement works only with tape decks. Do not use it with any type of signal processing device.

When connected to PRE AMP OUT/MAIN AMP IN

1.You must leave the MONITOR button on the 901 active equalizer OUT (SOURCE, position 1) at all times.

2.Do not connect tape decks to the 901 active equalizer when it is connected to this amplifier connection. Connect the tape deck to the receiver or amplifier TAPE MONITOR connection or AUX inputs.

3.The power amplifier is always receiving the 901 active equalized signal. This signal can damage conventional speakers and headphones. Therefore, do not connect conventional speakers or headphones unless you have disconnected the 901 equalizer.

Do not connect tape decks or signal processing devices to the 901 active equalizer when it is connected between the preamplifier and main amplifier.

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.
