The SPEAKER SELECTOR SWITCH located on the froiI anel of your AX20 is inoperative for this application and may remain in any position. SECOND AMPLIFIER AX20 LEFT SPEAKER G 8 16 A 8 G 8 I6 SPEAKER RIGHT SPEAKER TO AUX INPUT OF SECOND AMPLIFIER O LEFT CHANNEL OUT SPEAKER HOOK UP OF AX20 AS STEREO AMPLIFIER IN CONJUNCTION WITH ANOTHER AMPLIFIER Figure B Connecting Both Amplifiers For Stereo Operation: Connect a shielded lead of any length up to 20 feet between the LEFT CHANNEL OUT jack on the rear of the AX20 and the AUX or TUNER input on your other amplifier. Nom: If the amplifier used for the second stereo channel is a combination AMFM tuner, amplifier and preamplifier such as the Harman-Kardon Festival, this connection will not interfere with normal Monaural AM or FM reception through the speaker connected to the combination unit. If you wish to use both amplifiers and speakers for monaural program material, a simple change in the internal wiring of the receiver can easily be made. The change (which is best done by a technician) consists of removing the wire from the Function Selector switch arm (refer to your original instruction book) and extending it out from the chassis. This-wire is connected to the AX20 LEFT CHANNEL OUT Receptacle. A new shielded wire is connected between the Function Selector switch arm and the TUNER Receptacle of the AX20. IMPORTANT: Connect the AC power cord from your monaural amplifier to the AC convenience outlet on the rear of the Model AX20. The on/off switch on the AX20 will now control the power for both amplifiers. Connecting Your Stereo Tuner: The FM output of your Harman-Kardon stereo tuner should be connected to the LEFT TUNER input jack located on the rear panel. The AM output should he connected to the RICHT TUNER input jack. The same method of installa- tion applies if you are using separate FM and AM tuners. Plug the AC line cord of your tuner into one of the AC convenience outlets located on the rear panel of the Model AX20.
