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.

2INTRODUCTION.0 AND FEATURES

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.
