The RCA-SM2 kit from Niles gives you easy control over your audio/video system, even if your gear is placed out of sight in a cabinet or closet. It includes everything you need to set up a complete IR (infrared) repeater system and control up to three A/V components:

  • MS220 IR sensor — Mount this small sensor in a convenient spot, like next to your TV. It sends the IR commands from your remote control to the IR hub.
  • MSU140 IR hub — Accepts incoming IR signals and passes them on to your A/V components.
  • three MF1 flashers — Infrared light-emitting devices that carry IR commands from the MSU140 to your A/V gear.
  • 50 feet of CAT-5 cable to connect the IR sensor to the IR hub.

Product Highlights:

Works Great

Crutchfield Customer Review (What's this?)

Bought this for the man cave when my original plan of bouncing the remote signals off of the tv screen didn't work. In hindsight, that was probably a bad plan. Easy to install, very straight forward. Would recommend.

Works for me!

Crutchfield Customer Review (What's this?)

Works well for my application. Relatively easy to set up, although the installation instructions are lacking with regards to extending the sensor past the 10' length wire already integrated. You have to use the 50' coax cable to extend it, but the instructions have no mention of it. All good though! Learned how to solder stranded wire as a result!

Pros: Product seems very reliable and well built. The base unit is heavy, which is a good thing to me.

Cons: Instructions seemingly hard to follow.

Easy set up, works excellent with harmony remote, a bit pricy but worth the buck compared to my old IR repeater

Pros: Quality, good manual and work excellent with all devices

Cons: A bit pricy

Worked just like advertised, with my harmony remote.

Pros: easy set up

Cons: none

Excellent Quality

Crutchfield Customer Review (What's this?)

This repeater is worth the price tag. That was my fear and my reservation. Installation was easy. I used the supplied 50' cat5 cable to extend the signal back to my audio cabinet which is in the back of my theater room. The eye picks up the signals effortlessly and transmit the signal in a powerful way. I really wish I would have bought this years ago. It is leagues better than the radioshack RF repeater I have been using.

Pros: Exceptional quality, easy installation.

Cons: A little pricey, but may just be worth it.

Crutchfield Customer Review (What's this?)

To start I have this ir repeater controling my Onkyo 709, Samsung Blue Ray, and Verizon HD DVR and have a Harmon 1100 remote and a Samsung P 59 D8000 plasma. I tried to control everything with my Harmon remote through the Logitech RF Extender, but for what ever reason could not get it to work very well. I was very frustrated, but the silver lining was that the Crutchfield customer support was amazing! Absolutely the best I have ever seen and is the benchmark for other companies to follow. They sent me a new remote and RF Extender (even though I was sure it was just the extender with problems)to trouble shoot the control problems. After this didn't work. I went with the Niles RCA SM2. They sent it to me in two days, it was easy to set up, and bottom line, it works perfectly! The components are high quality and the the overview/details of the performance by Crutchfield are exactly correct. It works seemlessly with my Harmony remote....or any other of my remotes for that matter. It has allowed me to save face with my wife after a month of trouble shooting with the RF Extender with no luck. For that reason alone it was worth every penny!!!!

Pros: Works as advertised. High quality

Cons: none

EXCELLENT option for IR Repeater- Don't look elsewhere!

Written By GK1Impulse, Long Island, NY on Thursday, September 29, 2011

Crutchfield Customer Review (What's this?)

I can't say enough about this product. Harmony One Remote, Samsung plasma, Onkyo 608 receiver, Samsung Blu-Ray and Directv HD box are in play here. I had tried out the "cheaper" Sanus option before- no luck- I've heard that the Plasma can throw things out of whack on lower end repeater components.

Went to Niles as a result and am so happy that I did. From the time when it was removed from the box to install, less than 30 minutes. Flashers are EXTREMELY responsive and the receive has great range. You will not regret picking up this unit. The one thing to note- Crutchfield says that it controls 3 units- not true. You only get 3 flashers in the bundle but it has the ability to control 4 units via 4 flasher inputs. Also, you can add "double" flashers to each input which means that if you ever wanted to, you could control 8 units. IR Receiver is very small, about the size of your thumb and easy to conceal.

You will never regret purchasing this unit - a quality product! Go for it!

[Editor's Note: Thank you for bringing this to our attention. We have updated our database, and added additional flashers under our "Accessories" tab.]

Crutchfield Customer Review (What's this?)

I wanted to remotely control both my TV set top box and my DVD player so that I could watch them on the TV on my deck outside. I attempted to use a RF remote control at first but the IR signals did not work with my newer equipment. I bought the Niles remote extender and it works perfectly! Very easy to install and the 50' of Cat 5 cable was just the right length for my installation. It has been working flawlessly.

Niles IR Receiver works great. I prewired my house with CAT5 at ea tv location so setting it up was easy. Only wish they'd package with connectors to splice the small wires together. Other that that very satisfied.

MSU140 Main System Unit Features
MS220 IR Sensor Features
MF1 MicroFlasher Features


IR System 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.

IR System Components: This infrared extender system includes the following items:

  • IR Main System Unit: The MSU140 IR Main System Unit provides a connection hub for the IR sensor or keypads and up to four IR flashers, and it is generally located near the A/V components. The Main System Unit is the heart of an IR extender system.
  • IR Sensors: IR Sensors, like the included MS220 surface mount model, 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 CAT-5 or a 4-conductor shielded cable. Generally, sensors are placed so that you can easily and naturally point your remote control directly at them. Sensors are also available in wall-mount, ceiling-mount and tabletop models.
  • IR Flashers: These IR MicroFlashers re-transmit the infrared signals from the IR Main System Unit to your A/V components. Flashers are the voice of an IR extender system that speaks to your components.

MSU140 Main System Unit Features

Universal Compatibility: With the necessary accessories, an IR remote control extender system using the MSU140 is compatible with virtually all brands of A/V equipment and remote controls using carrier frequencies between 26 kHz and 105 kHz.

Wiring: If the distance from the IR sensor to the MSU140 is longer than the attached 10' cable, it can be extended with the included 50' Category 5 (Cat 5) 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.

Status Input: The MSU140 features a 3-30-volt AC/DC status input jack which provides system status to sensors and keypads when connected to a switched AC or DC output on an audio receiver or preamp. An optional 12-Volt adapter may be necessary.

MS220 IR Sensor Features

Universal Compatibility: When used in a complete system, this IR sensor is compatible with virtually all brands of A/V equipment and remote controls using carrier frequencies of between 25kHz and 90kHz. The MS220 is also compatible with the recently introduced Philips RCMM codes.

Universal Noise Suppression: The sensor has a patent-pending Universal Noise Suppression design that effectively eliminates IR interference from plasma and LCD TVs, CFL (fluorescent) lighting, and direct sunlight. This two-stage technology combines an optical noise filter with a smart electronic circuit to provide consistent, reliable control.

IR Receiving Range: You get 20' to 35' of remote control range, depending upon the strength of your handheld remote. The IR pickup angle is 30° off-axis (horizontal and vertical) at 25'.

Bi-colored LED: The LED glows green when the system is on and flashes blue to confirm reception of IR commands.

Mounting: The MS220 is designed to surface-mount almost anywhere using its adhesive back. Convenient mounting locations for the MS220 include: on the front panel of a television set, on the front surface of a wall, a cabinet, an appliance, or a speaker grille.

MF1 MicroFlasher Features

Universal Compatibility: When used in a complete system, this IR MicroFlasher is compatible with virtually all brands of A/V equipment and remote controls using carrier frequencies between 20kHz and 455 kHz.

Mounting: The MF1 is designed for pin-point relaying of IR commands, so it is typically mounted to the infrared remote sensor window of an audio/video component using the self-adhesive backing. The flasher hoods can be used to block any ambient light or other remote signals. The MF1 has a transmitting range of up to approximately 4'.
