Bose Understanding 901 Equalizer Compatibility and Amplifier Requirements

English

Using Your 901® Series VI Speaker System

Equalizer compatibility

The Bose® 901® Series VI active equalizer is designed for specific use with

Bose 901 Series VI speakers. It may also be used with 901 Series V speakers.

WARNING: Bose 901 Series I, II, III, or IV speakers require a substantially

­different equalization. The 901 Series VI active equalizer must not be used with Series I – IV speakers. For additional information on the active equalizer, please contact Bose Service.

Connecting additional speakers

The type of speakers and how you will use them determines how many ampli- fiers and 901 active equalizers you will need.

To run other non-901 speakers simultaneously requires the addition of a second amplifier. To use other speakers simultaneously with the 901 speakers requires the ability to isolate the 901 active equalizer signal so that it affects only the 901 speakers.

Adding 901 speakers

You need just one 901 Series VI active equalizer to use a second pair of 901 Series VI speakers connected to a single receiver or amplifier. Connect the additional speakers to the additional speaker output jacks on the receiver or amplifier.

To use extra 901 speakers in a four channel or time-delay music system, you will need a separate 901 active equalizer for each pair of speakers.

Adding conventional speakers

You need a separate power amplifier to play conventional speakers at the same time as 901 speakers. Connect the 901 active equalizer to the amplifier that drives the 901 speakers only.

CAUTION: Make sure the conventional speakers do not receive signals from the 901 active equalizer.
