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 S7500-K2, 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. INTRODUCTION AND FEATURES High Power Capability The S7500-K2 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 Features The JBL Synthesis S7500-K2 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 S7500-K2 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. ® 8 2. 0 INTRODUCTION AND FEATURES Quiet Cooling The S7500-K2 utilizes a fan to cool the amplifier channels, ensuring long-term reliability. To reduce fan noise to an absolute minimum, a thermal sensing and control circuit has been incorporated in the Synthesis S7500-K2 that senses increases in temperature within the amplifier and powers a fan at a speed proportional to that temperature increase. [. . . ] Make sure that the screw terminal and DIN adapter cables to speakers are correctly wired and are connected to the correct jacks on the S7500-K2. Make sure that all required DIN cables are connected between system components. Check the power outlets and make sure that there is a solid earth ground present.
