These CAUTION marks are located on the bottom of your 901® active equalizer: The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated dangerous voltage within the system enclosure that may be of sufficient magnitude to constitute a risk of electric shock. [. . . ] 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. 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. 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. 9 Setting Up 3. Connect one end of a cable to the AMPLIFIER INPUT jacks on the 901® active equalizer. Connect the other end of the cable to the OUT or RECORD jacks on your receiver. Connect the second cable from the AMPLIFIER OUTPUT jacks on the 901 active equalizer to the IN or TAPE jacks on your receiver. Plug the power cord of the 901 active equalizer into one of the switched outlets on the receiver so that it will be powered when the receiver is switched on. Figure 5 Connecting to the tape monitor connection Home theater use (PRE AMP OUT/MAIN AMP IN) Use these instructions: · for stereo-only operation if your receiver does not have a TAPE MONITOR connection. · if you are using a surround sound receiver that has a section on the back marked PRE AMP OUT/MAIN AMP IN. The jacks may be labeled ADAPTER or SIGNAL PROCESSOR. Note: If your receiver does not have this PRE AMP OUT/MAIN AMP IN section, the 901 speakers will not be usable in your home theater system. 1. The PRE AMP OUT/MAIN AMP IN jacks on your receiver are usually connected by small bars called horseshoe pins. See Figure 6.

Use the twin cable assemblies (with two connectors at each end) that are supplied with the equalizer. Use one connector for the right (R) channel connections and the other connector for the left (L) channel connections. Connect the amplifier INPUT of the Bose® 901® active equalizer to the PRE AMP OUT jacks of the receiver or amplifier. Connect the amplifier OUTPUT of the active equalizer to the MAIN AMP IN jacks on the receiver or amplifier. Plug the power cord of the 901 active equalizer into one of the switched outlets on the receiver so that it will be powered when the receiver is switched on. Note: This connection method does not allow you to connect a tape deck directly to the active equalizer. [. . . ] 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. Call Bose Corporation for assistance with the connection of additional speakers or signal processing equipment. Refer to the address information on the inside back cover of this guide.
