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-bladed 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
Four outlets are fed power through the heart of the MAX® 5510, the Isolation Transformer. These outlets should be used for
digital components like DVD players, CD players, and laser disc players.
Pure, clean power is obtained by using the isolation transformer to regenerate AC current. The power from a typical wall
outlet is often 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 trans-
former'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 isolates your digital source equipment from contaminated power, and prevents any noise generated in the system’s dig-
ital components from flowing back to other connected equipment.
Two different power filtration modes, Isolated and Balanced, are available as output from the isolation transformer. These
are selected with the front panel AC Regeneration pushbutton. In the Isolated mode, the secondary (load side) of the trans-
former’s winding is completely isolated from ground connections.
In the Balanced mode, a center tap wire from the secondary winding is connected to ground. This creates a balanced volt-
age waveform (+60V Line-Ground & -60V Neutral-Ground, 180 degrees out-of-phase), that still provides 120VAC to your
equipment.
More information regarding the Isolated and Balanced power filtration modes may be found in the Introduction on page 2
and the Technical Descriptions on page 12.
A 3-position slide switch (Isolation Transformer 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 sec-
onds to prevent internally generated surges. 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 informa-
tion.
When set to one of the delay positions (10 or 30 seconds), the Isolation Transformer Outlets are controlled by the Switched
Outlets pushbutton and/or the DC Voltage Sense Triggers. In this setting, the Isolation Transformer Outlets will not power
down until after the selected time delay has elapsed.
