Clean-up the sound and protect yourexpensive home entertainment equipment. A “must have” accessory for high poweramps. High current sequenced turn on/turn off outlets for amplifiers and othercomponents prevents spikes to equipment and “thumps” to speakers. Surgeprotection plus EMI and RFI filtering The ACE-515 is a High Quality AC powersurge and power conditioning system. The ACE-515 has a total of 7 outlets: 2High Current for Amplifiers, 1 un-switched outlet and 4 switched outlets. It isblack and has an on/off switch on the front panel. The unit has 6 foot powercable and an additional 6 foot cable for turn on by another component. Thepower cord with two-prong plug is a sensor cord that is meant to be pluggedinto a switched outlet of a controlling device like a preamp, CD player etc.When the controlling device is turned on, power is sent to the sensor cordwhich in turn triggers the switched outlets of the ACE-515. This way you canpower up an entire system by turning on a single component. This unit is testedand in great condition. This is a high quality unit with long heavy-duty cablesthat will not only improve the sound and help protect your equipment, butreduce the wiring mess behind your gear. LINK: Accessories Regardless of howsophisticated your audio/video system is, it may never achieve its fullpotential when plugged directly into a standard AC outlet. Why? Standard ACoutlets often supply raw, unprocessed power that not only diminishes theclarity of audio signals and reduces video resolution but can actually damagethe sensitive circuit elements inside your valuable components. ADCOM's ACE-515AC Enhancer protects your system and significantly improves its performancecapabilities three ways. First, it provides effective surge protection fromlarge "spikes" that may be injected into the AC line byrefrigerators, air conditioners, heating systems, and even atmosphericdisturbances. Second, the ACE-515 filters and processes AC power to provide apure, noise free power source. Third, it prevents audible "thumps" bysequentially switching your system components on or off. The ACE-515 combinesboth a switchable circuit breaker and internal MOVs (Metal Oxide Varistors) toprovide convenient and effective protection against potentially damaging highvoltage AC transients. The ACE-515 responds to these surges within 10nanoseconds and can safely dissipate over 10 joules of transient energy. ACnoise filtering also includes protection against both radio frequency andelectromagnetic interferences (RFI and EMI). The audible results are bestdescribed as an "unveiling" of both musical and visual details topresent more depth and vibrancy in the resulting images. The ACE-515's seven ACoutlets (six switched, one unswitched) are grouped to allow central connectionof up to four source components, one control center, and up to two poweramplifiers. Sophisticated delay circuitry turns on the power amplifier(s) onlyafter all other components have stabilized, and turns off the source componentsonly after the power amplifier(s) have had time to fully discharge their powersupplies. Plug in the ACE-515 and reach your full potential.
