Nice room needing ultra wide bandwidth infraared repeatingInfrared repeater systems are used primarily for two reasons.

1. To hide components in a cupboard or cabinet and control these components with a remote control when the cabinet doors are closed.

2. To allow the use of an infrared remote control in one room to control components in another room.

Our latest versions of the IR320k, IR350k and IR440k infrared repeaters now work great with all difficult to control cable and satellite receivers (dvrs and pvrs).  If there is an infrared repeater problem and Knoll can't fix it, you won't find a brand that will.

Infrared remotes require an unobstructed view between your remote control and the device it is controlling in order to function as intended. For example- when someone stands between you and the TV, you cannot change the channel, because the signal is blocked from reaching the TV.

Choose Knoll for the smallest size infrared receivers (the part you see). For the cleanest looking family room or home theater TV setup you will want to hide the Blu-ray players, surround sound receivers and cable boxes inside a cupboard or cabinet which also protects them from being damaged.

Knoll infrared repeaters use wires to extend the IR signal around corners, behind entertainment centers, or any situation where line-of-sight between your devices and your remote control is not possible.

ULTRA BANDWIDTH RULES!Knoll has the widest bandwidth infrared!

Knoll's huge "piece of mind" technical advantages in the 300 series are:

1. Automatic gain control. Regardless of the incoming infrared signal level the outgoing signal level is automatically corrected giving the same output when used in direct sunlight and with weak remote control batteries (makes batteries last longer).

2. Ultra bandwidth with automatic error correction. To control todays cable and satellite boxes, ultra wide bandwidth is critical. If wide bandwidth is not properly kept in check too much unwanted signal gets thorough and bogs the whole system down making it practically unusable. Automatic error correction monitors any incoming signals and unwanted signals outside of the critical 25 kHz to 65 kHz band are automatically rejected, giving a superior repeater capability when used in sunlight, with plasma and LCD TV's, infrared burglar alarm systems and especially with compact fluorescent lighting (CFL's) notorious for screwing up infrared repeaters.

3. Native carrier frequency transmission. If wide bandwidth signals are to be faithfully reproduced (to work with all cable boxes and satellite boxes) the only way to make IR repeaters work is to use native carrier frequency transmission. Some brands just strip off the carrier frequency then with an adjustment add a single carrier frequency back on. A single carrier does not work with many of the newer cable and satellite boxes as well as other lower band products like Blu-ray players at the same time.   

4. The IR155 connection hub is dimmable. For years installers have struggled placing an emitter "off-center" in just the right place as its output is too strong and saturates the component infrared system it is trying to control. Knoll has answered this struggle by adding a dimmer emitter port. The installer now needs to place the emitter on the component and dim its output until the component responds properly. Another Knoll "first"... 

 

The new 400 series includes all of the 300 series advantages above and

Adaptive code filtering. This process is brand new and it runs a very fast analysis of the incoming signal to establish if it is a real infrared signal. If it is not and it is just noise it may get rejected. If it is real, it is processed and repeated. Just ensures it is the most reliable and trusted infrared repeater system ever made…
