The Coronet has been designed with but one aim in mind - to provide a complete high fidelity sound system for the home that will satisfy the mogt critical eledtronic and aesthetic requirements. Towards tlis end, the FISHER RADIO CORPORATION has chosen the finest stereophonic components and com- bined these with a master-crafted custom console. The result is a musical in- strument of exceptional quality that will enhance the decor of the most beauti- fully appointed home.
Two separate, remarkably sensitive tuning sections bring you stereophonic or monophonic FM and AM broadcasts. Combined with the tuning sections is a Master Audio Control Center which permits you to adjust every nuanoe of sound over the entire audio speclrum. A dual-channel Power Amplifier supplies 45 watts of undistorted music power. The world-famous Garrard Record Changer, equipped with a magnetic stereo cartridge and a dia-ond LP stylus, will faithfully reproduce every t)?e of monophonic LP and stereophonic record available. Lastly, two multiple-speaker systems are provided to reproduce the full panoramic sweep of stereophonic sound - from the simplest musical passage to the most complex orchestral cresendo.
Advanced electronic desiga, the use of costly, durable materials, and un- hurried fabrication - the necessarJrelements in maintaining the level of excel- lence that is often lost in mass production - all of these will contribute toward bringing you years of trouble-free performance and unsurpassedlistening pleasure. These are the qualities which have for over two decades created the world wide reputation enjoyed by F'ISHER products.
A NOTE ON STEREOPHONICSOUND
Stereophonic sound is a giant step forward in the history of high fidelity music reproduction. This unique dual-channel system offers a distinct advantage over monophonic (single-channel) systems by virtue of two important character- istics - the dimensions of. d,irection and, depth. These liue sound qualities are for the most part missing in monophonic syste-" because records are rirade and reproduced over a single channel. This is analogous to listening to music with one ear. Stereophonic recording techniques, however, utilize two separate banks of microphones which are positioned in the left and right seetions of the orohestra, In this arrangement, the misysphones "hear" the music as we do--with

two ears. The sound picked up by each bank of microphones is then fed to independentchannels and recorded on disks or tape, or transmitted over separate channels of a stereophonicbroadcast.
To reproduce orchestral realism in the home, two separatesound systemsare required io achieve the stereophoniceffect. The stereo sound output of a record pluy"r, tape recorder, or tuner is fed to two separate amplifier channels,which i., iurl drive two separatespeaker systems.Thus, instruments located on the left side of the orchestraare heard predominately in the speakersto your left (Channel A) ; instrumentson the right side of the orchestraare heard predominantly in tlre speakersto your right (Channel B) ; while instruments located in the center ap- pear to be heard midway betweenthe two speakersystems. The result is a startling sense of presence realized only at a live orehestral performance.
Stereophonic radio programs are now available in some areas through FM'AM or FM-FM broadcasts. The Coronet can be used for FM-AM broadcasts directly. To receive FM-FM transmissions, an additional FM tuner is required. In the near future, stereophonicproglams will be broadcast over a single FM station, using one of several propor"d methods of FM multiplexing. When a standard system ol FM multiplex transmission is adopted, you will be able to listen to these plograms in full stereophonicsound by adding a FISHER multiplex adaptor to your Coronet. Such adaptorswill be made availableby FISHER RADIO CORPORATION as soon as FM multiplex broadcasts are licensed by the Federal Communications Com' mission.
The Coronet is provided with facilities for easy installation of the revolutionary new FISHER Spacexpander Model K-10. By adding the Spacexpander to your Coronet, you will be able to create the perfect illusion of concert hall sound in your own listening room. The Spacexpanderefiectively increasesthe acoustic dimensions o{ your room by adding the controlled reverberation of the best concert halls. We recommend that you ask your dealer for a demonstration of this startling new development.
(c) www.fisherconsoles.com The sound system of the Coronet is equipped to accomodate any type of additional Tuner, Tape Recorder or Record Changer you may wish to use to listen to the various kinds of program material. See the section entitled "Con- necting Additional Components," on page 10, for further information. The Coronet is also-equipped with a Center Channel Output to which an additional amplifier and loudspeaker may be eonnected to be used at another location.

Ihe Coronet operates on AC only. Conr'Lecttle power cable at the back of the cabinet to a wall outlet supplying 105 to 120 volt AC, at 60 cycles. Maximum power co$iumption is 160 watts. (Vhere line voltage is too high or too low, a step-down or step-up transformer will be necessary. For 50 cycle current, a .p""irl adaptor pullef is required for the Record Changer turntable.
