Optional Power Supplies may be substituted: Model S1460, International AC Adapter/Recharger (110/220V, 50/60Hz). Model S1462, 12 Volt DC adapter (automotive cigarette lighter plug-in). Model S1465, NiCad Battery Pack. (Note: 6V AC Adapter stored in accessory bag is for use with CD Player only!) TO INSTALL OR REPLACE BATTERIES Remove Reading board. Loosen two wing nuts on battery holder bracket. Remove battery holder from amplifier. Insert 10 new Alkaline “D” cell batteries, be sure to observe polarity, or replace with Model S1465, NiCad battery pack. Carefully replace battery pack. Replace battery holder bracket. Tighten two wing nuts and replace reading board. Do not mix battery types or attempt to recharge alkaline batteries - equipment damage, safety hazard or fire could result. CD, CASSETTE PLAYER Each requires AA batteries loaded on the backside of each unit. TO OPERATE: Plug microphone into DYNAMIC microphone jack. Plug the extension speaker lead into right SPEAKER jack. Turn amplifier on (large rocker switch located on the front of the amplifier). The red light will go on, showing that power is available. Rotate VOLUME control knob to obtain desired loudness level throughout the coverage area. ON-OFF When power switch is in the ON position, the red light will be on. DC IN Connection for optional power adapter: • S1460 International AC Adapter/Recharger (110/220V, 50/60Hz) • S1462 12 Volt DC (automotive cigarette lighter) Adapter LAMP Connection for 12 to 15V DC accessory VOLUME Rotate clockwise to increase amplification. MICROPHONE INPUTS There are three microphone inputs, which can be used simultaneously: DYNAMIC - for standard dynamic cartridge microphones CONDENSER - for electret or condenser microphones which require phantom power (Supplied from the amplifier) WIRELESS - accepts line-level output from wireless microphone receiver when used with S132A AUXILIARY To add pre-recorded music or sound effects during your presentation, just connect your CD player, tape player or computer sound card into the AUXILIARY LINE IN jack using a 6’ stereo cable (supplied), then plug into the phone jack on CD or cassette. Separate VOLUME and TONE control knobs let you balance the program source with the live microphones. If using an external wireless receiver, for best sound quality it should be connected to the LINE IN jack. OUTPUT To tape record your speech or program, connect the LINE OUT on the amplifier, using a 6’ stereo cable (supplied), to the input on a tape recorder. SPEAKERS Two separately amplified speaker jacks (4-8 ohms) allow you to use one or both speakers for additional sound power or true stereo output. Base unit speaker is wired internally. Plug external speaker into left speaker jack for stereo. Note: when using a stereo AUX source with a single speaker, only one of the stereo channels will be heard. However, all MIC inputs are heard equally on both channels. PROBLEM SOLVING FEEDBACK is the howl or screech often heard in sound reinforcement systems. It is caused by sound from the loudspeaker returning to the microphone. AmpliVox systems utilize proven acoustical principles to minimize this; however, there is no way to completely eliminate howlback under conditions of high amplification. If feedback occurs check the following: 1. User’s hand covering the head of the microphone. [Hold microphone under head slots.] 2. Sounds can easily re-enter microphone. Keep loudspeaker turned toward audience. Note: sound can be reflected from a hard surface back through the microphone. [Turn speaker.] 3. User holding microphone in a reflecting position. [Turn microphone.] 4. Volume setting too high. [Reduce microphone channel volume; compensate by speaking louder or closer to the microphone.] NO SOUND Make sure amplifier POWER switch is turned on and red LED is lit. If switch is on and LED is not lit, check to see that batteries are properly connected and at full charge. If using optional power adapter, check to see that front panel connector is properly seated, and verify that the power source is live.
