AC Enhancer:
Regardless of how sophisticated your stereo and video system is, it may never achieve its full potential when plugged directly into a standard AC outlet. Why? Standard AC outlets often supply raw, unprocessed power that not only diminishes the clarity of audio signals and reduces video resolution but can actually damage the sensitive circuit elements inside your valuable components.
Adcom's ACE-515 AC Enhancer protects your system and significantly improves its performance capabilities three ways. First, it provides effective surge protection from large "spikes" that may be injected into the AC line by refrigerators, air conditioners, heating systems and even atmospheric disturbances. Second, the ACE-515 filters and processes AC power to provide a pure, noise free power source. Third, it prevents audible "thumps" by sequentially switching your system components on or off.
The ACE-515 combines both a switchable circuit breaker and internal MOVs (Metal Oxide Varistors) to provide convenient and effective protection against potentially damaging high voltage AC transients. The ACE-515 responds to these surges within 10 nanoseconds (10 billionths of a second!) and can safely dissipate over 10 Joules of transient energy.
AC noise filtering also includes protection against both radio frequency and electromagnetic interferences (RFI and EMI.) The audible results are best described as an "unveiling" of both musical and visual details to present more depth and vibrancy in the resulting images.
The ACE-515's seven AC outlets (six switched, one unswitched) are grouped to allow central connection of up to four source components, one control center and up to two power amplifiers. Sophisticated delay circuitry turns on the power amplifier(s) only after all other components have stabilized and turns off the source components only after the power amplifier(s) have had time to fully discharge power.

The Adcom GFS-3 is a high-quality speaker selector switch that gives you the flexibility to run up to 3 pairs of speakers off of a single pair of amplified speaker outputs (up to 200 watts per channel). When selecting and using multiple pairs of speakers simultaneously, the protection circuit built into the GFS-3 is designed to protect both speakers and amplifier without sacrificing sound quality.
The GFS-3 was specifically created to prevent the harm that can result from having multiple pairs of speakers present too low an impedance load on your amplifier; this condition can cause your amplifier to cut power output and result in unpleasant distortion. Pushing the “Protection” button on the GFS-3 inserts added resistors into the amplifier-speaker line so that the amplifier is able to work efficiently within its operable impedance range, protecting your amplifier and speakers and preserving audio quality.
The Adcom GFS-3 accommodates up to 3 pairs of speakers with unparalleled features and protection:
* Wide-contact, heavy-duty switches capable of handling the full output of amplifiers up to 200 watts per channel
* High-quality circuit board design with wide signal traces for minimum power loss
* Heavy-duty components designed for long life
* Easy-to-connect twist-lock input and output terminals ensure positive contact with both speaker and amplifier cables and lock in the cable ends to prevent accidental disconnection
* Selectable Minimum Impedance Protection™ circuitry for optimum flexibility
* Massive load resistors provide protection for your amplifier when driving multiple speaker systems
* Dimensions - Chassis: 8 5/8"(219mm) W x 2 7/8"(73mm) H x 5 7/8"(149mm) D
