INTRODUCTION

INTRODUCTION

Thank you for selecting the ClearCom frequency agile, PRC-2 IFB 
Receiver. The PRC-2 is the result of extensive engineering experience 
with the very latest components.  The design addresses the most 
demanding professional applications.

Figure 1-1: PRC-2 IFB Receiver

The ClearCom PRC-2 Receiver along with the companion PTX-3 
transmitter allow on-air talent to monitor program audio, and to receive 
cues from directors and other production personnel.

The PRC-2 Receiver is housed in a rugged, machined aluminum 
package for lasting performance in abusive environments

Only the PRC-2 IFB Receiver is covered in this manual. The 
companion PTX-3 transmitter is covered in a separate manual.  The 
PRC-2 IFB Receive will operate with any ClearCom PTX-3 IFB 
Transmitter in the same frequency block.

GENERAL TECHNICAL DESCRIPTION

The PRC-2 has a number of important and useful feature upgrades:  
1. Two rotary HEX switches to manually set the operating frequency
2. Automatic sensing/control of a mono phone plug to eliminate the 

mono/binaural switch

3. A multi-color LED for battery status.  The Frequency scan and 

memory features were retained.

The PRC-2 Receiver is comprised of a  number of functional 
subsystems as shown in Figure 1-2 Control Panel and Figure 1-6 
Receiver Block Diagram.
