DESCRIPTION The Electro-Voice model E-V SEVEN system is a carefully designed two-way reproducer offering outstanding performance in an enclosure of sur- prisingly modest demensions. Lower distortion and wide frequency range are achieved by the use of two separate drivers, each handling a special portion of the audible spectrum, The component- quality S-inch woofer features such refinements as Alnico V magnet, precision-wound voice coil, and a linear suspension which allows long, vet carefully controlled, excursions. Frequencies above 2000 cps are handled bya three- and one-half inch specially-constructed, cone-type tweeter which provides exceptionally smooth treble response without undesirable harshness. Excellent high-frequency dispersion insures lifelike realism, especially when the E-V SEVEN is used in stereo applications. A two-way electrical crossover pro- vides smooth transition from one driver unit to the other. Finest quality components including encapsulated inductors are employed for maxi- mum power handling capacity and frequency accuracy. The attractive E-V SEVEN enclosure is rigidly constructed throughout and is handsomely finished in walnuton all four sides. The nameplate may be rotated to permit either horizontal or vertical placement.

Generally however, the most realism will be obtained if its height from the floor is near the listener's ear level. Placement in a room corner assures maximum efficiency and bass reproduction, since the room walls are made an integral part of the system, acting as the sides of a large horn. The E-V SEVEN performs equally well placed in a horizontal or vertical position and the nameplate may be rotated Lo accommodate either placement, The above comments apply also to stereophonic placement. Additionally, however, the two systems should be far enough apart to permit listeners to sit at the apex of a thirty- to forty-degree angle, as illustrated. A distance of six to eight feet be- tween stereo speakers will, in most rooms, pro- vid “tural separation. Placing the loudspeakers tu. close together or listening at too great a dis- tance will destroy the stereo effect, and the sound heard by the listener will be essentially mono- phonic. Extreme spacing between speakers or listening at too shorta distance will produce exag- gerated and unreal separation. In long rooms, the loudspeakers should be placed along one of the short walls facing into the long room dimension. This improves bass reproduction and provides good stereo listening over most of the room.

Connections should be made between the Part No. 531419 E ELECTRO-VOICE, INC. / Buchanan, Michigan leftterminal (T1) and the amplifier 8-ohm terminal; the right terminal (T2) should be connected to the amplifier" common’ terminal (sometimes referred toas "QO" or ""C"), Connections should be made with No. 158 or larger wire; common zip- or lamp-cord is quite satisfactory. If the speaker leads are to be run behind a molding strip or under a carpet, 300-chm TV twin lead should be used. ADJUSTMENT OF BALANCE CONTROL The E-V SEVEN is equipned with a continuously- variable balance control to adjust the high-frequency response of the system to varying acoustical en- vironments. The "normal" position, indicated on the control, should be correct in most instances. Acoustically "hard" or "live" rooms may require a retarded setting of the control to compensate for the greater amount of high-frequency reflection. In "soft" or 'dead" rooms with carpeting, soft furniture, and draperies, an advanced setting of the control will normally be required. The best guide to setting the control properly is a familiarity with the sound of live music. That position of the control which provides the musical balance most satisfactory to you is correct. CUSTOMER SERVICE Your E-V SEVEN system has been packed to pro- vide protection well in excess of shipping require- ments of the Interstate Commerce Commission. If shipping damage does occur, contact the dealer from whom the unit was purchased or the carrier and request inspection and further instructions. The E-V SEVEN is guaranteed indefinitely against defects in original workmanship and materials. If your system becomes damaged or develops faulty operation from unusual conditions of use, write to the Electro-Voice Service Department requesting return authorization and shipping instructions. Be sure to mention the make and model number of the other components used in your system. 27 CHMS ++ WOCFER 3 MFD, 18 CHMS YELLOW + TWEETER п С COM ñ BLACK = COM Figure 3 - Schematic Diagram 6/65 Litho in U.S.A.
