INTRODUCTION

Phase Linear Corporation welcomes you to the world of exquisite sound reproduction. The
Phase Linear 700-Series Two amplifier is your personal carrier into the realm of state of the
art high fidelity, Your Model 700 is the finest. most advanced amplifier today's technology
can produce.

You are encouraged to thoroughly digest the followrng manual in order to understand and be
able to use your amplifier. Briefly. your Phase Linear YOU-SeriesTwo is a precision high power
audio amplifier designed to meet the rugged requirements demanded in professional applica-
tions. it is capable of amplifying a wide range of frequencies with extremely low harmonic and
intermodulation distortion and very low noise. Advanced state of the art technology has been
incorporated into the Model 700. The extensive use of integrated circuits makes possrble an
amplifier with performance which in the past had been virtually unattainable.

The output crrcurtry utilizes 20 rugged 150 watt silicon power transistors providing a power
handling capacity of 3000 watts! The output transistors operate in the Phase Linear quasi-com-
plementary configuration which exhibits proven excellence in performance and reliability. A
massive heat sink structure provides more than adequate cooling for the amplifier.

Your 700-Series Two is equipped with elaborate overload protection systems to insure safe and
reliable operation. If the amplifier is accidentally connected to a short circuit or an exceedingly
low impedance load. a voltage-cu rrent limiter ci rcuit serves to keep power dissipation in the out-
put transistors within limits. Fuses in the power supply circuit provide additional protection by
preventing abnormally large current flows in the amplifier. Complete thermal protection is pro-
vided by a built-in protection circuit If an excessive amount of heat is generated in the amplifier.
the power will be disconnected automatically to avoid reaching unsafe operating temperatures.

Output voltage and power levels of each channel are displayed simultaneously with light emit-
ting diode (LED) arrays. These displays have peak responding characteristics to permit accurate
observations of output voltage and power levels.

A front panel switch is provided to increase the sensitivity of the display by 20dB for more
accurate indication of low level operation.

Before leaving the factory your Phase Linear Model 700 amplifier was tested and certified to be
in perfect operating condition. This manual will help you operate the TOO-Series Two as well as
keep it in perfect condition and should be put away for future reference. With care befitting all
fine instruments. your Phase Linear 700-Series Two will provide years of musical enjoyment.
