JBL S800 - Manual (Page 9)

Introduction
Congratulations on your purchase of this JBL
Synthesis S800 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 performance; 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 S800 only in accordance with its instructions.
Features
The JBL Synthesis S800 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.
Multi-Channel Operation
The S800, a two channel amplifier that can also be
operated in bridged-mode as an extraordinarily
powerful single-channel amplifier (typically when used
to drive a subwoofer), has been designed to integrate
well into the world of multi-channel audio. When
coupled with the five channels available in the S650A,
or the seven channels of the S7150, they are 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 S800 provides a truly satisfying 200 watts per
channel of clean audio (<0.03% THD) into eight ohm
loads, and 800 watts when operated in bridged-mode
into an eight ohm load, making it ideal for powering
subwoofers and surround speakers, which are frequently
less efficient than front speakers. Because of their power
capabilities, all Synthesis amplifiers have an extremely
wide dynamic range, an element critical to realistic home
cinema. Sound pressure levels equal to those present 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 S800 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 S800, S650A, and S7150 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.
