The EP-C-15 provides noise-free filtered AC distribution to your audio/video equipment with much lower resistive losses than any other product in its category. For rackmount use - see EP-C-15R

The EP-C-15 uses proprietary filters to remove the unwanted noise and RFI without causing a "bottleneck" to the flow of AC current to your power-hungry equipment.

Unwanted AC line noise occurs in two forms: common-mode and differential mode. Common-mode noise appears simultaneously on both the line and neutral conductors with respect to ground. RFI from radio stations, for example, is a form of common-mode noise. Differential mode noise occurs between the line and neutral AC conductors and is in series (that is, rides on top of) the desired 50/60 Hz waveform. Computer power supplies, monitors, printers, and lighting dimmers are typical examples of the kind of appliances that can introduce DM noise into your household wiring.

Eliminating the noise and RFI from your AC line means that your equipment will not have to amplify and process RFI along with the audio and video signals. Using an EP-C-15 to provide your system with clean, filtered AC power will allow you to fully experience and enjoy all the promised performance from your system.


The Solution
The EP-C-15 uses low-loss 3d order (18 dB per octave) bidirectional AC line filters to reject both common-mode and differential mode AC noise and RFI from the AC outlets feeding your sensitive audio/video equipment. The noise reduction capability of the unit extends to much lower frequencies than competing AC filters. The accompanying graph shows the reduction of noise at various frequencies from incoming power line to any output. Because of their bidirectional nature, the filters also prevent backfeeding of equipment-generated noise into the incoming AC line. Additionally, because each duplex receptacle (output group) is fed by a separate filter, the same reduction in noise occurs between any output group and any other output group. The most sensitive front-end audio components are isolated from your power amps and other potential noise makers by feeding them from separate output groups. This filtering is extraordinarily effective. At the relatively low frequency of 300 kHz, the unit reduces differential mode noise by a factor of 175 to 1 and common-mode noise by more than 125 to 1! At 500 kHz, the beginning of the AM radio band, the EP-C-15 filters have attenuated differential-mode noise by over 300 to 1 and common-mode noise by more than a factor of 700 to 1. This exceptional low frequency rejection of both externally generated noise and noise backfeeding from a switchmode power amplifier will greatly benefit your sensitive front-end components.
