Setting Up
5. Move the receiver BALANCE control to the extreme left and then to the extreme right.
This tests the left and right channel orientation. If the channels are reversed, check the
connections.
6. Turn off the receiver and temporarily unplug the 901
®
active equalizer from its AC (mains)
power outlet.
7. Turn your receiver back on. You should not hear any music through the system. If you
do, the equalizer is probably connected incorrectly. Check the equalizer connections.
8. Turn off the receiver before restoring AC power to the 901 equalizer. Plug the equalizer
back in to its AC outlet. The system is now ready for use.
Using other equipment
You can use the Bose
®
901 active equalizer TAPE CONNECTION jacks for a tape deck,
VCR audio connection, signal processors, or other components. This will be necessary if
your receiver has only one tape connection and you have connected the equalizer to it. If
you connected the equalizer to the receiver’s TAPE 2 connection, you can use TAPE 1 for
these components.
Before making any connections, turn off the receiver and components. Be sure the active
equalizer power indicator is off.
To add a tape deck or VCR:
1. Use cables with RCA connectors at each end. One color (usually red) is for right (R)
channel connections and the other connector is for left (L) channel connections.
2. Connect the TAPE RECORDER OUTPUT of the equalizer to the LINE IN/REC of the tape
deck. Connect right channel to right channel and left channel to left channel.
3. Connect the TAPE RECORDER INPUT of the equalizer to the LINE OUT/PLAY of the
tape deck. Connect right channel to right channel and left channel to left channel.
Note:
To use an external signal processor, or to add a graphic equalizer, contact Bose for
more information. Refer to the inside back cover of this guide.
