Safety Instructions
To maximize user safety and ensure correct device operation, all instructions contained in
this section should be read carefully.
Caution: It is important that the user observe all warnings and instructions
that are on the unit and contained in this manual.
Before Applying Power
Warning: DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Operation of the PS Series in the presence of flammable gases or fumes
can endanger persons proximate to the site of operation.
Verify that the line voltage is 220VAC
Ground the Amplifier
Caution: DO NOT REMOVE THE AMPLIFIER COVER
Removal of the amplifier cover will invalidate the warranty. Component
replacement and internal adjustments must be made only by PTEK
qualified service personnel.
To minimize shock hazard, the exciter chassis must be connected to an electrical ground,
the exciter must be connected to the AC power mains through a three-conductor power
cable, with the third wire connected to an electrical ground (safety ground) at the power
outlet. Any interruption of the protective (grounding) conductor or disconnection of the
protective earth terminal will cause a potential shock hazard that could result in personal

injury. If the exciter is to be energized by any other source be certain that the chassis is
connected to a separate safety ground.

AC Line Fuses and Trips
The PS Series power amplifiers are provided with an 8 gauge 3 conductor
“pig tail” AC Line cord. This should be wired into a breaker box and feed
with a 2 pole 35A breaker.
Output Connector
Warning: The Flange output connector carries dangerously high RF
voltages that present shock and burn hazards. Never operate the PS power
amp without properly terminating the output connector in either an
adequately rated load or antenna.
Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can destroy static-sensitive devices or
micro-circuitry. Proper packaging and grounding techniques are necessary precautions to
prevent damage. Always take industry-standard precautions.
Grounding Methods
Guard against electrostatic damage at workstations by following these steps:
1. Cover workstations with approved anti-static material. Provide a wrist strap connected to
a work surface and properly grounded tools and equipment.
2. Use anti-static mats, heel straps, or air ionizers to give added protection.
3. Handle electrostatic-sensitive components, boards, and assemblies by the case or the PCB
edge.
4. Avoid contact with pins, leads, or circuitry.
5. Turn off power and input signals before inserting and removing connectors or test
equipment.
6. Keep the work area free of non-conductive materials such as ordinary plastic assembly
aids and Styrofoam.
7. Use field service tools, such as cutters, screwdrivers, and vacuums that are conductive.

General Safety Rules
The device must be used in accordance with the instructions for use.
Electrical installations in the room must correspond to the requirements of respective
regulations.
Take care that there are no cables, particularly mains cables, in areas where persons can
trip over them.
Do not use a mains connection in sockets shared by a number of other power consumers.
Do not use an extension cable.
Only use the mains cable supplied.
The unit is completely disconnected from the power source only when the power cord is
disconnected from the power source. Therefore, the power cord and its connectors must
always remain easily accessible.
Do not set up the device in the proximity of heat sources or in a damp location. Make
sure the device has adequate ventilation.
All plugs on the connection cables must be screwed or locked to the chassis housing.
The device is designed to be used in horizontal position only.
The device is no longer safe to operate when the device has visible damage or the device
no longer functions.
In case of system malfunction or visible damage to the PS Series, the device must be shut
down and secured against unintentional operation.
Repairs may only be carried out by authorized PTEK personnel.

Preface
This document, PS Series Operating Manual and User Guide, provides
instructions on how to install, configure, power up, and perform diagnostics on
the PS series Transmitter (see photo below). The information contained within is
intended for an experienced system operator with a knowledge of high-
performance broadcast transmission systems. The 4RU-high (7.0”) PS
transmitters are designed to fit a standard 19” rack.
PS Series Broadcast Transmitter
8 PTEK April 2016
Key features of the PS Series PTEK Transmitter include:
Totally solid-state no-tune construction
Wide input range from 210 to 264 VAC
Remote-control interface
Built-in stereo generator
Meets or exceeds all FCC and CCIR standards
Designed and manufactured in the United States
The PS Series are FCC-type verified for use on FM stations. Frequency stability for each
unit is ensured by using Direct Digital Synthesis (DDS) frequency synthesis with a highly
stable crystal oscillator. All units incorporate over-temperature protection and VSWR
foldback to automatically reduce power output to safe operating levels.
Switch-mode power supplies provide consistent performance even when there are
frequent power outages and voltage fluctuations that make stressful demands of power
dependence. An overview and specifications of the PS Series PTEK Transmitter is given
in Chapter 1 of this manual: “Overview and Specifications.”

Overview and Specifications
1.1 Overview
The PS Series are FCC-type verified for use on FM stations. Frequency stability
for each unit is ensured by using PLL (phase-locked loop) frequency synthesis
from a highly stable crystal oscillator. All units incorporate over-temperature
protection and VSWR foldback to automatically reduce power output to safe
operating levels.
Switch-mode power supplies provide consistent performance even when there are
frequent power outages and voltage fluctuations that make stressful demands on
power dependence.
The 4RU-high (7.0”) PS Series is designed to fit a standard 19” rack.
