INSTALLATION INSTRUCTIONS
MODEL AA-10 PAGING AMPLIFIER
Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL APPLICATION INFORMATION:
Wheelock's AudioLink Series Model AA-10 Paging Amplifier is output rated at 10 watts RMS.
This amplifier affords a choice of three different inputs: one low impedance microphone input, one telephone paging input, and one high impedance auxiliary input. Three input channels allow these inputs to be used actively at one time: one microphone input, a telephone paging input, and one auxiliary input. Note that the auxiliary input (i.e., background music, tone generator, etc) will automatically be soft muted whenever a telephone page is generated or a microphone is used. After completion of the page, the music will rapidly return to its original level.
A built-in limiter circuit compensates for the varying voice levels and paging styles of the people who have access to telephone paging or a microphone. The limiter maintains rated output without distortion.
The amplifier features tamper-resistant individual input volume controls, as well as a master volume control, individual treble and bass controls, a low-cut horn protect switch, power on indicator, and a peak level indicator.
The unit operates from 115 volts, 60Hz and has a power consumption of 35 watts. The unit has a thermal breaker in the power transformer as well as thermal cut-off and current limiting for overload protection on the output. The thermal breaker in the transformer is automatically resettable.
NOTE: All CAUTIONS and WARNINGS are identified by the symbol 
. All warnings are printed in bold capital letters.
CAUTION: In the event the transformer's thermal breaker does not reset, have the trouble investigated by an authorized service technician or return unit to the factory.
WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
UNPACKING:
The amplifier was carefully checked before leaving the factory. Inspect shipping container and unit carefully for indication of improper handling. If the unit has been damaged, make an immediate claim to the carrier.
MOUNTING INSTRUCTIONS:
The amplifiers are designed for either shelf or wall mounting. For surface wall mounting, use the 2 keyhole slots in the chassis cover. Be sure to use hardware suitable for the mounting surface. Do not block air flow to top or bottom. Blocking the air flow will cause automatic thermal shutdown.
CAUTION: These devices are not intended for use in hazardous locations as defined by the National Electrical Code (NEC) and by the National Fire Protection Association (NFPA).
WARNING: DO NOT USE THIS UNIT IN LIFE-SAFETY APPLICATIONS. THIS UNIT IS UL 813 LISTED AND CUL LISTED FOR COMMERCIAL AUDIO ONLY.
POWER AND GROUNDING:
The 115 VAC line cord has a three-prong plug which should be plugged into a three wire grounded electric outlet. It is very important to maintain the amplifier ground for safe and trouble-free operation. If there is no grounded electric outlet, use a 2 prong to 3 prong plug adapter, with grounding lead, and connect the grounding lead to a metallic bond on the outlet; (i.e. the screw which secures the outlet's wall plate).
