Bose 901 - Manual (Page 2)

I. Introduction
The BOSE 901 represents a fundamental advance in realistic
home music reproduction. The unique acoustic design of the speakers
provides sound distribution in accurate simulation of live sound. The
BOSE 901 Active Equalizer provides unprecedented accuracy and
control of frequency response characteristics.
Because the BOSE 901 system differs fundamentally from
other speaker systems, IT IS IMPORTANT THAT THESE INSTRUCTIONS
BE CAREFULLY FOLLOWED. EACH STEP IS ESSENTIAL FOR PROPER
OPERATION AND FULL PERFORMANCE OF THE BOSE 901 . PAR­
TICULAR ATTENTION SHOULD BE PAID TO SECTION V: CONNECTING
THE 901 ACTIVE EQUALIZER.
n. Unpacking
The 901 system is carefully packed for shipment in sturdy
cartons. Remove the two speaker units, the Active Equalizer and the
bundle of four audio cables. These items comprise the 901 system.
Any damage should be immediately reported to your dealer.
ni. Speaker Placement
Your BOSE 901 speakers have been designed to provide su­
perior sound radiation characteristics. To obtain the best results, you
must place them correctly in the room according to the guidelines in­
dicated in this section.
1. Because of their unique radiation characteristics, the
separation of the speakers is not highly critical in rooms of
normal size. In fact, these speakers may be placed further
apart than is possible with most other speaker systems and
they will still yield excellent stereo without the common "hole
in the middle". Therefore, in most rooms you are free to use
either a short or a long wall for the placement of your speakers
as indicated in Figure 1. You may experiment with the distance
between the speakers to suit your taste but if possible the sepa­
ration should be at least six feet.
