The IRB1 infrared (IR) flasher helps enable easy control of your A/V system from a secondary listening room, using either your system's regular remote control or a universal remote. A complete IR repeater system, which also includes an IR system hub and one IR sensor for each secondary listening room, not only gives you A/V system control from multiple rooms, but also lets you place your components out of sight in a cabinet or closet.

Here's how an IR repeater system works: In any of your secondary listening rooms, simply point your remote control at the mounted IR sensor and press a button. The sensor relays your command to the IR hub, which passes the signal on to the IRB1 flasher, which in turn transmits your command to the relevant A/V component in your system.

The IRB1's high-power output allows this single flasher to convey IR commands to an entire stack of A/V components. Its adhesive backing allows easy mounting, and its steamlined design fits neatly inside a cabinet door or at the top of an equipment rack.


  • high-power output
  • controls an entire stack of A/V components
  • includes an adhesive-backed strip for quick and secure mounting
  • includes 10 feet of connecting wire terminating in a 3.5mm connector
  • compatible with virtually all infrared-remote controlled components
  • 1"W x 3/8"H x 2-1/4"D
  • warranty: 2 years

Works Great

Crutchfield Customer Review (What's this?)

I was struggling with the single flashers on a couple of my devices. Mounted one of these using the high output setting on the MSU250 and it's working flawlessly.

Pros: Works great

Cons: None so far. Wish it had been included in the original device set.

Excellent product

This product works as advertised. I have and will continue to buy products from Crutchfield.

My experience is identical to the review by Otnip. I needed a replacement for the older Niles model IRP2+ and this works perfectly.



Replacement for the Discontinued IRC-1

Written by: Otnip from Texas on January 22, 2012

Crutchfield Customer Review (What's this?)

I have a discontinued Niles IRP2+ IR extender which uses the discontinued Niles IRC-1 (and IRC-2) flasher. My IRC-1 flasher was no longer functioning and I purchased the IRB-1 flasher as a replacement.

I couldn't find any documentation (on the Niles and Crutchfield sites) on replacements for the discontinued Niles flashers, so I bought this one not knowing whether it would actually work.

It worked perfectly as a replacement. I needed to cut the 3.5mm plug because the IRP2+ uses screw terminals. The wire lead with the stripe is (+). I connected it to the "full" flasher terminal.

Works reliably inside my cabinet controlling several different devices, including an Apple TV.



Hi Output IR flasher

Written by: AL from Connecticut on April 13, 2011

Crutchfield Customer Review (What's this?)

These things are amazing! I have them in a AV cabinet that has two racks. I installed one on each side with the self adhesieve peel off [that is still sticking] to the ceiling of the wooden cabinetry. If the doors are open it is exposed to sunlight, compact fluorescent lighting, Led lighting, and it continues to work perfectly. I expected to have to fool around adjusting locations but it works great! Very reliable!
I'd highly recommend this product!

Product Research


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 IRB1 is a high-output flasher, typically known as a flooding flasher, that relays infrared commands using flashes of IR light in a flooding pattern. When properly placed, it's powerful enough to control an entire stack of components (very tall stacks may require a second flasher). It is one of three elements that make up an infrared extender system:

  • 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.
  • IR Main System Unit (sold separately): The IR Main System Unit provides a connection hub for the IR sensors and the IR flashers and is generally located near the A/V components. The Main System Unit's level controls and LED indicators enable you to calibrate and troubleshoot an IR extender system. The Main System Unit is the heart of an IR extender system.
  • IR Flashers: Infrared Flashers transmit the infrared signals from the IR Main System Unit to your A/V components. Niles manufactures both flooding flashers (models IRB1 and IRC1) and miniature pin-point flashers (model MF1VF). Flashers are the voice of an IR extender system.

Dual IR LEDs: Two high-output LEDs give the IRB1 exceptional range and IR emitting power.

Compatibility: The IRB1 will control most makes and models of IR-controlled A/V components (those with remotes using carrier frequencies between 26 and 60 Hz), and it's compatible with most Niles infrared repeaters (not compatible with the MSU 140), infrared routers, and multi-zone keypad systems.

Works with any infrared systems. Using mine on Denon receiver and Uverse tv box. [ JOE D  Aug 21, 2015 ]
I have this working about 3 different TV brands and a Uverse cable box. It really works well. [ Anthony  Aug 19, 2015 ]
I need to add to my previous answer - my basic niles unit has a couple of "high output" jacks in addition to the regular ones. I didn't know what they were for till I found out about the high output flasher. So check to see if your unit has the high output input jacks. If it does I bet it will work. [ Alan  Aug 19, 2015 ]
I can't answer definitively. I have a niles system with the smaller flashers that just wasn't working great. So I got this flasher, plugged it into my existing niles system, and centered it inside the cabinet and it solved the problem! I don't have time right now to check what model the unit is that I plugged it into, but you can get it and if it doesn't work return it. Also, call the crutchfield folks directly - they're service is always helpful and responsive. Good luck. [ Alan  Aug 19, 2015 ]
