The new, moderately
prieced Bose Model 550 AM/FM Stereo Receiver brings you Bose technology and
research wrapped up in an affordable, innovative package. It includes a
direct-coupled amplifier that delivers a solid 40 watts of RMS power per
channel - enough to drive almost any loudspeaker. It has an excellent AM/FM
tuner section for clean reception. And exclusive Bose Source and Room
Compensation Controls let you adjust for recording characteristics and for room
acoustics. These controls make it easy for you to remove mid-range boominess
without losing your deep bass. Try that with a conventional receiver.
The Bose 550
Receiver is designed to drive any speakers that suit your taste and budget. And
it contains a unique feature you'll really appreciate when you upgrade your
system. More and more customers tell us their first loudspeakers are interim
units and that one day they hope to invest in a Bose 901 Series
Direct/Reflecting Loudspeakers System.
Ownwrship of the 550
Receiver brings that day much closer, because the receiver has a built-in 901
Active Equalizer that gives you a significant savings when you purchase 901
speakers.
