Wheelock's AFT-100 is an AM and FM tuner designed to provide background music over a paging system, and music-on-hold to a telephone system.
Separate telephone system and line level outputs, each with it's own volume control allow connection to a wide variety of paging, background music, and
telephone systems. A built-in monitor speaker, tuning dial, LED signal strength indicator, and automatic frequency control provides ease of station
tuning, while minimizing signal drift. In addition to a built-in telescoping and fully pivoting FM antenna, a separate FM dipole antenna is provided, as well
as terminals to connect an external FM antenna. Selector switches allow selection of : AM-FM bands; internal-external antenna; speaker on-off; and
power on-off. A tone control to adjust bass and treble response, is also provided. Barriered screw terminals are provided for ease and reliability of
installation. The tuner can be powered by 12VDC or 24VDC, and is designed for surface wall mounting.

POWER SUPPLY CONNECTIONS

Using a 24VDC Power Supply

1. Connect (+) from 24VDC power supply to 24VDC (+) terminal on AFT-100.

2. Connect (-) from 24VDC power supply to 24VDC (-) terminal on AFT-100.

Using a 12VDC Power Supply

1. Plug power supply cord into 12VDC receptacle in bottom of AFT-100. Power supply plug polarity must match AFT-100 receptacle polarity (See

Figure 1). Recommended 12VDC power supply is the Wheelock EPS 1205.

CAUTION: Exceeding specified maximum input voltage can lead to failure of the unit.

ANTENNA AND OUTPUT CONNECTIONS (See Figure 2):

1. For use as background music source, connect LINE OUT to music input of paging system.

2. For use as music-on-hold, connect TEL OUT to music-on-hold input of telephone system. Do not connect to telephone lines.

NOTE: This output can develop .5 Watt into 8 Ohms and may be too strong for telephone systems that incorporate line-level amplification stages

for music-on-hold. In these cases the LINE OUT send may also be used for the telephone system's music-on-hold input.

3. If using an external antenna for FM reception, connect to ANT 300 ohms terminals.

NOTE: Antenna is not required for AM reception.
