Our take on the Niles MSU140

The MSU140 infrared extender hub helps enable easy control of your A/V system from a second room, using either your system's regular remote control or a universal remote. It also lets you place your components out of sight — in a cabinet or closet, for example — and still easily operate your system.

The MSU140 infrared extender hub helps enable easy control of your A/V system from a second room, using either your system's regular remote control or a universal remote. It also lets you place your components out of sight — in a cabinet or closet, for example — and still easily operate your system.

The MSU140 serves as the "hub" of an infrared (IR) extender system. You'll also need an infrared sensor to mount in your secondary listening room — this sensor receives the IR commands emitted by your remote control and relays them to the MSU140. The MSU140 in turn passes these signals to an infrared flasher, or emitter (also sold separately) that sits near your A/V components and transmits your commands to them. (Depending on the components in your system and their placement, more than one flasher may be necessary.) To complete your IR extender system, you'll also need some wire to run from your IR sensor to the MSU140.

  • one IR sensor input
  • four IR flasher outputs
  • UL-listed, regulated in-line power supply with universal voltage capability
  • system feedback LED provides visual indication of operation
  • integrated mounting wings accommodate both vertical and horizontal installation
  • rugged all-metal chassis
  • 4-3/4"W x 2"H x 13/16"D
  • warranty: 2 years

Works perfectly! Very easy install

Inputs and Outputs


Overview:  An infrared (IR) extender system enables you to control your IR remote controlled A/V equipment from a remote location. This enables you to 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. The model MSU140 is an IR Main System Unit. It is one of three elements that make up an infrared extender system:

  1. IR Sensors (sold separately): IR Sensors receive IR commands from hand-held remote controls and relay the commands to the Main System Unit via a 2-conductor shielded cable. Generally, sensors are placed so that you can easily and naturally point your remote control directly at them. Niles offers an array of easily concealable sensors: wall-mount, ceiling-mount, surface-mount and table-top. IR sensors are the "eyes" of the system.
  2. IR Main System Unit: The MSU140 IR Main System Unit provides a connection hub for one IR sensor or keypad and up to four IR flashers, and it is generally located near the A/V components. The Main System Unit, which is the "heart" of an IR extender system, has LED indicators to monitor the IR extender system.
  3. IR Flashers (sold separately): Infrared Flashers transmit the infrared signals from the IR Main System Unit to your A/V components.

Universal System: With the necessary accessories, this IR remote control extender system is compatible with virtually all brands of A/V equipment and infrared remote controls (virtually all brands of remotes using carrier frequencies between 18 and 100kHz).

LED Displays: A built in green LED provides a visible indication of system status and a built in blue LED blinks to confirm the reception of IR data.

Power Supply: The power supply has a detachable 6 foot AC input cord and a 6 foot hardwired DC output cord. The adapter accepts 100-240V, 50/60Hz AC input, and it outputs 12VDC.

Wiring Requirements: An individual run of category 5 cable is all that is required to connect an optional sensor or Niles Intellipad to the MSU140 (in most US states and municipalities, cable must be "CL" fire rated). The optional Niles IR flashers come with 10 foot leads attached, and the leads can be extended with 16 gauge, two-conductor cable.

Inputs and Outputs

Power Socket: Provides fast and convenient connection of the power supply.

Status Socket: 3.5mm jack provides system status to sensors / keypads via a 12 volt power supply attached to a switched outlet on the system receiver or a 12 volt trigger output.

Remote Sensor Input: 4-pin connection for use with the included screwless quick connect sensor connector; allows you to connect an IR sensor or keypad to the MSU140.

Flasher Connections: four 3.5mm mini plugs for single or dual low-level flashers, such as models MF1, MF2, MF1VF and MF2VF; these connections are not compatible with high power flashers, such as the IRB1.
