FEATURE DETAILS
Filtered Outlet Banks 1 & 2
Four outlets (two banks / two outlets per bank) are fed through separate "Balanced, Double L" noise filtration circuits. These
circuits are designed to eliminate the noise contamination of the AC power that is most detrimental to the performance of
analog or video components like stereo receivers, VCRs or televisions. The two dedicated filters are carefully engineered to
provide power filtration and inter-component noise isolation for both common-mode (line/neutral-to-ground) and normal-
mode (line-to-neutral) EMI/RFI. This means that high-frequency interference will be drastically reduced not only from the
incoming power but also from equipment plugged into the other outlet banks, regardless of what "mode" it occurs in. Even
equipment with ungrounded, 2-blade plugs, receives clean power.
Both banks remain ON continually (Always-On) to provide a constant power source for programmable analog or video com-
ponents. A personal video recorder (such as TiVo™) and VCR are two examples of components that require constant power.
A TiVo™ video recorder relies on continual power to monitor the cable signal and retain its programmed information. A VCR
should be connected to one of these always-on, filtered outlets to maintain correct clock time and programmed recording
information.
Isolation Transformer Outlet Bank (Isolated Outlets)
Four outlets are fed power through the heart of the MAX
®
5500, the Isolation Transformer. These outlets should be used for
digital components such as DVD players, CD players, etc.
Pure, clean power is obtained by using the isolation transformer to regenerate the AC current. The power from a typical wall
outlet is contaminated with electromagnetic (EMI) and radio frequency (RFI) interference (noise) picked up by the power lines
between the power utility’s generating plant and the wall outlet. This contaminated power feeds the isolation transformer's
primary winding and is regenerated (through electromagnetic induction) as clean power on the isolated secondary winding.
The outlets are connected to the secondary winding, which has no conductive connection to the primary winding. This is
True Isolation! Not only will it isolate your digital source equipment from contaminated power, but will also prevent any noise
generated in the system’s digital components from flowing back to other connected equipment. The secondary (load side)
winding is completely isolated from ground connections as well, eliminating ground loops and hum.
A 3-position slide switch (Isolated Outlets Turn-Off) located on the rear panel controls the timing for the Isolation Transformer
Outlets. Together, these outlets can be set as Always-On or with a turn-off delay of either 10 or 30 seconds to prevent speak-
er “thump”. This switch provides the option of having a total of eight Always-On outlets (4 Filtered Outlets and 4 Isolation
Transformer Outlets). See the
Sequential Startup/Shutdown
section for more information.
When set to one of the delay positions (10 or 30 seconds), the Isolation Transformer Outlets will remain as Switched outlets,
controlled by the Switched Outlets pushbutton and/or the DC Voltage Sense Trigger. In this situation, the Isolation
Transformer Outlets will not power down until after the selected time delay has elapsed.
