MODEL AF310 AM RECEIVER/MONITOR
OPERATION MANUAL
GENERAL:
The Model AF310 is a precision AM (mono) broad-
cast receiver designed for EAS or other monitoring
purposes. The receiver is PLL (phase lock loop)
controlled. The frequency of operation is selected
using internal DIP switch combinations. A continu-
ous LINE receiver output is provided as well as a
SPKR audio output for driving an 8 Ohm monitor
speaker. The receiver is designed for the most de-
manding sensitivity, distortion, and signal to noise
requirements. There are Carrier and Modulation
indicators. Balanced audio output as well as Carrier
Level operated Relay outputs are available as an op-
tion.
AF310 AM Receiver: Front View;
Rear View (Receiver w/o Relay Option )(DIN)
The receiver circuit board has 10 VDC automotive style regulators. Input power is derived from wall mounted
power converters (115 VAC to 12VDC, 300mA) or other 12 VDC sources. The receiver is housed in a metal
case or configured as one receiver in the AFC3 multiple receiver rack mount chassis.
