Here's a great way to add extra music options to your vehicle without replacing your factory radio. The KCA-R71FM controller/FM modulator allows you to connect Kenwood's SIRIUS satellite radio tuner, Music Keg digital media player, or CD changer to any car radio. It's a great option for drivers of classic cars, people who lease their vehicles, and anyone else who wants to keep the "factory" cosmetics of their dash.

The package includes an FM modulator (converts the music signal from one of the Kenwood source units into an FM signal), a wired display/control panel, and a convenient wireless remote. Mount the wired display near your radio for easy operation and control. Connect a Kenwood SIRIUS tuner to the KCA-R71FM, tune to an unused FM frequency, and prepare to be entertained by over 100 channels of SIRIUS programming! Select from 12 FM frequencies for the best possible reception in your area. The SIRIUS channel name and number, artist, or song title are displayed in a scrolling text format across the backlit screen.

You can connect the Music Keg or CD changer to the modulator, or better yet, connect one of them to the pass-through input on the SIRIUS tuner, and use the source selector on the KCA-R71FM's display panel to switch between the two. The display allows you to navigate through MP3 files and folders, access repeat, scan, or random play modes, and read ID3 tag information (artist, album, song title).

Adjust the volume of the playback to match your radio with the modulation level control, or use Dynamic Control to boost high frequencies for extra clarity. In addition to the wired control/display panel, you get a handy 10-key wireless remote.

Features

Overview: This FM modulator/controller allows you to add a Kenwood Sirius Satellite Radio tuner to your vehicle's existing radio in order to receive Sirius Satellite Radio broadcasts. Alternatively, you can connect a Kenwood CD changer or Music Keg digital media player to this unit.  If using the Sirius SIR-KEN1, Kenwood KTC-SR901, KTC-SR902, or KTC-SR903 Sirius Satellite Radio tuner, you can use the pass-through input on the tuner to connect the changer or Music Keg, and then switch between the two sources with this FM modulator/controller.

12 Modulation Frequencies: The output can be modulated on one of 12 different frequencies. They range from 87.7 MHz to 89.9 MHz in 200kHz steps (87.7, 87.9, 88.1, 88.3, 88.5, 88.7, 88.9, 89.1, 89.3, 89.5, 89.7, and 89.9).

4 Step Modulation Level: This feature lets the user adjust the output level of the modulator to best match the radio's input, which reduces distortion when playing CDs.

Dynamic Control: This feature automatically controls the level and separation of the FM modulator output to better match the FM radio's input. This reduces noises and distortion when playing CDs.

Text Scroll: This display/controller allows you to scroll through various text information automatically. However, this feature can be turned off to allow you to manually scroll through text data.

Auxiliary Input Ready: You can connect an auxiliary audio source to the FM modulator/controller when the KCA-S220A, CA-C1AX, or a CD changer with an auxiliary input function installed is used.

Line Outputs: The FM modulator/controller provides a stereo RCA line output, allowing you to feed the output to a receiver with an auxiliary audio input. This allows you to connect the output of a Music Keg or Sirius tuner directly to a receiver's preamp inputs.

FM Modulator Dimensions (hideaway unit): W=5.269", H=1.283", D=3.451 (incl. mounting tabs)

Great bang for the buck

Written By Chad, USA on Monday, August 01, 2005

Unlike plug and plays this product will never drop or static the Sirius tuner signal. I've installed several KCA-R7(X)FM controllers from Kenwood in many of my personal vehicals over the last few years, this is by far the best way I have found to add Sirius without changing to a new aftermarket headunit.

I currently have a unit in an '04 Acura TSX and the sound quality is fantastic. This is by far one of my favorite ways to add Sirius SAT radio to a non-SAT radio equiped auto.

And the remote is a great added feature.
