USING THE MODEL TA224 AS.AN INTEGRATED STEREOPHONIC CONTROL CENTER INSTALLATION PROCEDURE Ventilation: The unit is well ventilated in itself, but sufficient space must be allowed around it to permit proper air flow. Install the Stereo Recital in a manner to allow for unrestricted circulation. Do not place books or other objects on the cage or cabinet or in the immediate vicinity of the instrument. Reducing the air flow will result in sharply reduced component and tube life. Allow at least 4 inches above the unit when custom installing into a cabinet. Refer to mounting instruction sheet for cabinet installation procedure. Power Requirements: Plug the AC line cord into any outlet furnishing 117 volts, 50 or 60 cycles AC current. The voltage may vary between 105 and 125 volts. A 1 amp AC convenience receptacle is located on the rear nanel of the receiver and is controlled by the ON/OFF switch on the front panel. Connecting the Speakers: Your two speakers should be identical if possible to obtain optimum results. Experts agree that a perfectly matched system offers the best stereophonic reproduction. The speakers should be preferably placed along the same wall approximately 8 to 15 feet apart depending upon room size and furniture placement. It may be necessary to experiment with speaker placement until best results are obtained. Use any type wire to connect your speakers to the Stereo Recital. Lamp cord ("zip cord") is excellent and may be easily dressed around the molding for an inconspicuous and neat installation. Do not drive the staples or tacks through the center of the wire for this will short out the two sections and will decrease the overall volume or short out the speakers entirely. It is permissible to use approximately 100 feet of speaker connecting wire for each speaker without loss of volume. Connect one length of lamp cord to your left speaker and attach the other end to the screw terminals on the LEFT SPEAKER output strip. Connect one wire to the "G" terminal and the other wire to either the "8" or "16" ohm screw depending upon the nominal impedance rating of your speaker. (Impedance ratings are usually listed on the rear of the speaker or on the shipping carton.) Similarly connect another length of lamp cord to your right speaker and attach the other end to the RIGHT SPEAKER output strip. Connect one wire to "G" and the other wire to either "8" or "16" as previously discussed. Carefully dress the speaker leads away from audio input cables and power lines. Keep the wiring neat and be sure there are no frayed edges touching the chassis or other terminals. Connecting Your Speaker For Monophonic Operation: Connect your speaker to either the LEFT or RIGHT SPEAKER output strip according to its impedance rating. Connect an 8 or 16 ohm 25 watt wirewound resistor to the remaining SPEAKER output strip.
