FEATURE DETAILS
High-Current Outlet Bank
The two high-current outlets allow amplifiers and powered subwoofers to work to their full potential. When the movie thun-
ders with a terrific explosion or when the music reaches a climactic crescendo, an amplifier has to rapidly draw large amounts
of current to replenish its power supply capacitors. Traditional line conditioners impede this current draw, in effect, starving
an amplifier and resulting in a flat, dead sound. The High-Current Outlet Bank provides clean, filtered power to amplifiers
but has no current-limiting components to impede performance.
The high-current outlets are designed with a turn-on delay option of 0, 10 or 30 seconds. The 3-position, High-Current
Outlets Turn-On Switch on the back of the MAX
®
5500 is used to select the desired time delay. When a delay is selected,
the high-current outlets will turn on after the isolated outlets and turn off before the isolated outlets (if they are not set to
Always-On). With a delay, the connected equipment will not power up simultaneously, thus preventing loudspeaker noises
such as “thumping”. See the
Sequential Startup/Shutdown
section for more information.
Voltage Sense Trigger
This feature provides an ON/OFF trigger for the MAX
®
5500 using a DC remote control signal. Many components such as
pre-amplifiers and receivers have a 12VDC trigger built in, and will transmit a constant power signal when turned on and in
use. This power signal will initiate the startup or shutdown sequence of the MAX
®
5500’s switched outlets. An AC Adapter
of the appropriate voltage, plugged into a switched outlet, may also be used if a 12VDC trigger is not built in.
The MAX
®
5500 Voltage Sense Trigger input uses a standard 3.5mm mini-plug jack. This jack has an electrically isolated
switch built in. If nothing is inserted into the input jack, the voltage sense is bypassed and the MAX
®
5500 Switched Outlets
button on the front panel has sole control of the startup/shutdown sequence. If a plug is inserted into the input jack, the volt-
age sense becomes the startup/shutdown trigger.
Please note: The Switched Outlets pushbutton on the front panel
must be left in the “ON” position if you are using the DC trigger.
The circuitry for the Voltage Sense Trigger also controls the DC Voltage Trigger diagnostic LED on the front panel. When a
mini-plug is connected to the voltage sense input jack and a DC voltage signal is present, the LED will light to indicate that
the voltage sense circuit is ON and the MAX
®
5500’s switched outlets are ON. When the diagnostic light is not lit, the source
component is turned off and there is no DC signal.
The MAX
®
5500 also has the ability to pass through the DC signal from the voltage sense trigger to another slave device.
Please note: The Voltage Sense Trigger Output will not operate unless the Voltage Sense Trigger Input is con -
nected to a source.
Circuit Breakers
There are two separate circuit breakers on the back panel of the MAX
®
5500. The main circuit breaker will trip only if the
total current draw exceeds the maximum current rating (15A). This means that collectively, all loads must draw more than
15 Amps before the circuit breaker will trip. There is also a 4 Amp circuit breaker to protect the 500 VA Isolation Transformer
and its circuitry. The Isolation Transformer provides pure power for digital source components, which require very little cur-
rent to operate at peak performance.
Please note:
Do not plug high-powered amplifiers or powered subwoofers
into the Isolation Transformer Outlets. Their current requirements may exceed the 4 Amp limit and cause the
circuit breaker to trip.
