JBL S7150 - Manual (Page 8)

Introduction
Congratulations on your purchase of this JBL
Synthesis S7150 power amplifier! You have purchased
a product that embodies the best of what JBL has
learned about the emotional power of audio
reproduction in over fifty years of preeminence in the
field. This amplifier has been designed and crafted to
provide the user with a high level of sonic perform-
ance; special attention has been paid to minimize the
number of components in the audio signal path,
resulting in extremely low distortion, excellent transient
response, and wide dynamic range. Synthesis products
set new benchmarks in audio technology, and, when
used as part of a complete JBL Synthesis System, will
bring the ambience and acoustics of some of the world’s
greatest concert halls and theaters into your home.
To obtain the best performance from this amplifier, please
be sure to completely read this user’s manual and use
the S7150 only in accordance with its instructions.
Features
The JBL Synthesis S7150 power amplifier features the
following:
THX ® Ultra Specifications
This amplifier meets or exceeds the stringent specifications set
by the Lucasfilm THX Audio division in their specifications for
"Ultra"-class certification, including power handling, total
harmonic distortion, frequency response, signal to noise ratio,
slew rate, and crosstalk. When incorporated into a complete
THX system, you will hear in your home what the director and
sound engineer heard in the recording studio.
Full Seven Channel Operation
The S7150 has been designed to integrate well into
the world of multi-channel audio. It is one of the first
amplifiers designed to reproduce the latest development
in home theater audio; rear channels, in addition to
side channels, to produce a truly enveloping sound
field. When coupled with a high quality subwoofer
amplifier, such as the Synthesis S800, it is a solid
foundation on which to build a high-performance
home cinema system that will astound the listener
with its power and realism.
High Power Capability
The S7150 provides a satisfying 160 watts per channel
of distortion-free audio (<0.03% THD) into eight ohms.
Because of their power capabilities, all Synthesis
amplifiers have an extremely wide dynamic range, an
element critical to realistic home cinema. Sound levels
equal to those at original performances are easily recreated
in even the largest of home listening environments.
Auto Turn-On and Power Sequencing Circuitry
When used in a JBL Synthesis System, the S7150 can
be turned on automatically whenever the surround
processor is activated. No longer do you have to get
out of that chair to turn on the various pieces of
equipment in your entertainment system; just one
touch on the remote control of the surround processor,
and you’re a few seconds away from a truly impressive
audio presentation!
Modern amplifiers produce more power per channel
(and frequently have more channels) than those of the
traditional two-channel stereo era. Due to the high
current demands of power amplifiers at the instant of
turn-on, the S7150, S650A, and S800 amplifiers and
the SDEC digital equalizer are equipped with power
sequencing circuits which turn on each unit in
sequence, avoiding the large instantaneous current
demand (and possible house circuit breaker tripping)
that would occur should they all turn on at the
same instant.
