AUDIOLINK SERIES

INSTALLATION INSTRUCTIONS

MODELS AA-20/AA-40 PAGING AND COMMERCIAL PA AMPLIFIERS

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-20 and AA-40 Amplifier are output rated at 20 watts RMS and 40 watts RMS respectively.

These amplifiers afford a choice of four different inputs: two low impedance microphone inputs, 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

choice of a telephone paging input or a second microphone input, and an auxiliary input. Note that the auxiliary input (i.e.,

background music, tone generator, etc) may be automatically 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. This function is switch selectable.

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. This function is switch selectable.

The amplifiers feature tamper-resistant individual input volume controls, as well as a master volume control, individual treble and

bass controls, a low-cut horn protect switch, one input selector switch, a power on indicator, a limiter ON-OFF switch, a music mute

ON-OFF switch, a peak level indicator, and a line output jack.

Both models operate from 115 volts, 60Hz as well as 230 volts, 50Hz, switch selectable, and have a power consumption of 65 watts

(AA-20) and 115 watts (AA-40). The units have a thermal breaker in the power transformer as well as a 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, front, back 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).

VOLTAGE SELECTION:

Factory set @ 115VAC for U.S. market; units for export are set @ 230VAC. Make absolutely certain that the voltage selection

switch, located on the side of the amplifier, is set for the intended line voltage (i.e., 115VAC or 230VAC). Improper voltage selection

can result in permanent damage to, or failure of, the unit.
