At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
IR System Overview:
An infrared (IR) extender system enables you to control
your IR remote controlled A/V equipment from a
remote location. You can place your A/V
components out of sight (behind cabinet doors, in
the rear of a room, or in a different room) and still conveniently
control your equipment. Additionally the MSU440Z
has dedicated outputs for the signal from a given input, so you can control a
specific component, even if you have similar models from the same brand.
IR System Components:
The MSU440Z IR Main System Unit is one of three elements
that make up an infrared extender system:
IR Main System Unit: This Main System Unit provides a connection hub for
multiple IR sensors and/or keypads and multiple
IR flashers and is generally located near the A/V components.
The Main System Unit, the heart of an IR
extender system, has LED indicators to monitor
the IR extender system.
Sensors/Keypads (sold separately):
Sensors: The IR Sensors are the eyes of the system, receiving IR
commands from hand-held remote controls and
relaying the commands to the Main System Unit via a 4-conductor cable.
There are four sensor inputs, corresponding to the four zones. Generally, sensors are placed so
that you can easily and naturally point your remote control directly at
them. Sensors are available in wall-mount, ceiling-mount, surface-mount
and table-top models.
- Keypad: The IntelliPad
is a wall-mounted, programmable IR keypad system that provides a unique
LED power status display and the convenience of true one-button remote
control of complex audio/video systems.
- IR Flashers
Up to eight IR Flashers re-transmit the infrared signals from the IR Main
System Unit to your A/V components.
An IR command from any sensor/keypad zone is routed to a corresponding dedicated
flasher output which feeds only that zone's equipment. The MSU440Z prevents IR
conflicts by routing the remote commands from each zone only to the proper
components. Of the eight flasher outputs, four are dedicated single zone and
four are assignable to any combination of the four zones.
Universal Compatibility: With
the necessary accessories, an IR remote control extender system using the MSU440Z
is compatible with virtually all brands of A/V equipment and remote controls
(using carrier frequencies between 26 and 105 kHz).
Flasher Hi/Lo Switch: One of
the eight IR flasher outputs has switchable high/low output. When switched to
High, you can connect a high-output flooding flasher, such as an IRB1 (item
190IRB1). When in the Low position, you can connect low-output micro-flashers,
such as the MF1, MF1VF, MF2 or MF2VF.
LED Indicators: The MSU440Z
provides a visible indication of system status and IR reception via LEDs.
Wiring: From every IR sensor,
you must discretely wire (home-run) a Category 5 (Cat 5) cable back to the MSU440Z, connecting
each sensor to the hub with an individual cable. The Cat 5 cable should be
terminated with the supplied quick connect sensor plugs. The IR flashers connect
to the hub via 3.5mm (1/8") mini-plugs.
12 Volt Trigger: The MSU440Z
features a dedicated 12 volt DC/200mA output for each of the four zones,
triggered by a voltage or status signal from that zone. There is also a global
12 volt DC/200mA output, live when there is a voltage or status signal from any
Expandability: Using the IR
Cascade in and out jacks, multiple MSU440Z units can be used together for
additional system flexibility.
Contact Closure: The
MSU440Z has two three position quick connect plugs for connecting either NO
(normally open) or NC (normally closed) contact closure devices. There is a two
position switch that determines whether the contact closure is activated by either
the presence of status or discrete IR commands.
