READING LIGHT Depress light switch to activate light. [. . . ] mic input is balanced low impedance (600 ) and is phantom powered so condenser type microphone can be used. AUXILIARY LINE INPUT (1/4" PHONE JACK) The auxiliary input is used for playback of tape player, musical instrument, VCR, or an audio feed from another sound system. The volume control is located on dash panel. AUXILIARY LINE OUTPUT (1/4" PHONE JACK) The signal output is a composite of all the inputs and can be fed directly to an audio or video tape recorder. Or, the line output can be fed to another sound system to combine systems for greater output, or it may be fed to the input of a hearing impaired system. EXTERNAL SPEAKER OUTPUTS (1/4" PHONE JACK) OPTIONAL HEIGHT ADJUSTMENT Models with optional reading surface adjustment are controlled by the switch marked HEIGHT and provide up to 8 - 9 inches of elevation. To raise or lower, depress HEIGHT switch. SOUND MODELS Plug microphone into shock mount on reading surface. Turn main power switch located under reading surface on. Rotate "MAIN MIC", "TREBLE" and "BASS" controls fully counterclockwise to minimum volume position. Turn speaker switch located on dash panel to "on" position. While speaking into the microphone, slowly increase "MAIN MIC" volume by turning knob clockwise. The external speaker outputs can be used to drive external speakers in lieu of the internal lectern speaker. When a plug is inserted into the external speaker jacks, the internal speaker is disconnected. The powerful (50 watts) is adequate to drive several speakers provided the total load impedance is not less than 2 ohms. The output of the amplifier is self-protecting against overload; however, low impedance loads (below 2 ) will cause excessive heating reducing amplifier output. 1 STACKING MODELS To remove lectern top from projector stand base, disconnect power cord and turn the black knob (located under the middle shelf) counter-clockwise until disengaged. [. . . ] If your lectern fails to operate on a known power source, be sure to check the circuit breaker located on the Power Supply for a tripped condition. If breaker continues to trip, discontinue use of product until problem can be diagnosed. 2 LECTERN WIRING DIAGRAM ­ NON-SOUND SYSTEM LECTERN WIRING DIAGRAM ­ SOUND SYSTEM Sound System by Anchor Audio, Inc.
