Installation of MR253 (1 Channel) Audio Player Feedback Stabilizer

• Connect the MR253 between audio components like you would a normal RCA cable.

• The MR253 is not directional so both ends are interchangeable.

• Try to let the stabilizer hang freely so it is not affected by vibration.

• You may add extension cables if needed to make it reach between audio components, but for best results try not to or use extension cable as short as possible. The MR253 is 16 inches long but has a maximum span of 12.5 inches between RCA connectors. Put any extension cable on the side of the MR253 away from the audio player output.

• WARNING: THE PLAYER OUTPUT MUST BE ABLE TO HANDLE A CAPACITIVE LOAD OF UP TO 0.006uF. (Best results are obtained with players that can handle a capacitive load of up to 0.015uF.) THIS IS TRUE FOR MOST CONVENTIONAL COMMERCIAL PLAYERS. WHEN IN DOUBT (SUCH AS VACUUM TUBE OR OTHER UNCONVENTIONAL TECHNOLOGY), CONSULT THE MANUFACTURER.

Installation of R203/R103 (2 Channel) Audio Player Feedback Stabilizer

• Connect the two RCA plugs of the Feedback Stabilizer directly into left and right RCA outputs of your audio player. 

• Plug your RCA cable (not included) into the Feedback Stabilizer RCA jacks.

• Plug the other end of your RCA cable into the amplifier audio inputs

• Make sure you connect the Stabilizer directly to the player audio outputs (or as close as possible for best results).

WARNING: THE PLAYER OUTPUT MUST BE ABLE TO HANDLE A CAPACITIVE LOAD OF UP TO 0.004uF. (Best results are obtained with players that can handle a capacitive load of up to 0.015uF.) THIS IS TRUE FOR MOST CONVENTIONAL COMMERCIAL PLAYERS. WHEN IN DOUBT (SUCH AS VACUUM TUBE OR OTHER UNCONVENTIONAL TECHNOLOGY), CONSULT THE MANUFACTURER.
 

Example Installation of R203/103

In this example picture, a DVD player is shown. The same idea applies to CD players, VCRs, tape players, preamps, etc. A regular RCA cable (provided by the user) is shown connected to the stabilizer. The other end of this RCA cable would be connected to the amplifier inputs.

Remember, every player (or preamp) audio output needs its own Feedback Stabilizer. 
 

Installation of QR203/QR103 (4 Channel) and HR203/HR103 (6 Channel) Audio Player Feedback Stabilizer

• If you have a receiver with Preout jacks and do not use an external amplifier then connect the 4 (QR203/QR103) or 6 (HR203/HR103) RCA plugs of the Feedback Stabilizer directly into the RCA Preout Jacks. See picture below.

  - Make sure you connect the Stabilizer directly to the receiver Preout jacks (or as close as possible for best results).
  - If there is a subwoofer Preout use an RCA Y-cable to connect the subwoofer Preout to both the stabilizer and the subwoofer amplifier.
  - Tape off any unused RCA output plugs from the Stabilizer so it does not short to anything.
  - Installation of all 4 or 6 Channel Stabilizers are similar. Shown below is diagram of the HR103
  (6 Channels).

WARNING: THE PLAYER OUTPUT MUST BE ABLE TO HANDLE A CAPACITIVE LOAD OF UP TO 0.004uF. (Best results are obtained with players that can handle a capacitive load of up to 0.015uF.) THIS IS TRUE FOR MOST CONVENTIONAL COMMERCIAL PLAYERS. WHEN IN DOUBT (SUCH AS VACUUM TUBE OR OTHER UNCONVENTIONAL TECHNOLOGY), CONSULT THE MANUFACTURER.
 

• If you have a DVD / SACD player with multichannel RCA jacks (for example 5.1 analog outputs) or you have a Receiver / Processor connected to an external amplifier then use Y-cables to allow the 4 (QR203/QR103) or 6 (HR203/HR103) RCA plugs of the Feedback Stabilizer to tap off these RCA jacks. See picture below.

  - Make sure you connect the Stabilizer directly to the audio player outputs (or as close as possible for best results).
  - The stabilizer will not help the audio player if the digital connection is used to carry the sound. Make sure you are using the analog output of your player to transfer the sound to the amplifier/receiver.
  - Tape off any unused RCA output plugs from the Stabilizer so it does not short to anything.
  - Installation of all 4 or 6 Channel Stabilizers are similar. Shown below is diagram of the HR103
  (6 Channels).

Example Installation of HR203/HR103 onto a SACD / DVD-Audio Player

In this example picture, a DVD player with 5.1 analog audio outputs (6 channels) is shown. To connect the HR103 to this audio player, 6 RCA Y-cables are connected to the DVD player. One of the Y connections attach directly to the HR103 box so that it can tap off the DVD player's output. The other Y connection goes to the 5.1 analog inputs of the receiver, preamp, or processor using normal RCA interconnect cables (not shown). This RCA interconnect would attach to the red connectors in the picture below. The hookup for HR203 is identical.

Example Installation of Audio Player Feedback Stabilizer onto a Receiver Having Preamp Outputs

If you are using the digital inputs to a receiver, the "analog audio player output" is internal to the receiver and may be unreachable for stabilization. This may prevent you from realizing the full potential of sound quality offered by stabilizing the audio player analog output.

However, if your receiver has Preamp Outputs, it is still possible to stabilize the internal audio signals. Just connect the Audio Player Feedback Stabilizers into the RCA preamp out (PRE OUT) jacks. This stabilizes the internal analog audio circuitry. 

• The picture below shows a home theater receiver (such as Pioneer VSX-D812) where the Feedback Stabilizers are connected to the 5.1 "PRE OUT" RCA jacks. This offers the ultimate sound for home theater applications. In this example, an HR103 is used to stabilize the receiver's preamp outputs.
  (Notice that a Y-Cable is used at the subwoofer preout. This allows the Stabilizer to tap the subwoofer preout and also allow an RCA cable to connect to the subwoofer. In this case, the cable to the subwoofer (not shown) would connect to red connector).

Note: you can still use the preamp outputs to connect to an external amplifier if desired by using additional Y-Cables similar to what is done for the subwoofer preout.

• The picture below demonstrates the same type of stabilization as above, but utilizes R103s instead for all preouts.

Note: you can still use the preamp outputs to connect to an external amplifier if desired. Otherwise, leave the stabilizer jack unused. Tape off the unused RCA jacks so they don't short to anything.

If you do not have enough stabilizers for all preamp outputs, we recommend you first stabilize them in the following order:

1. Front Left and Right Channels
2. Center Channel
3. Subwoofer
4. Side Surround Channels
5. Back Surround Channels

Example Installations of Fm203 Onto Portable Music Player (such as iPod)

In the two following example pictures, an Fm203 stabilizer is connected to a portable music player. The headphone itself plugs into the jack on the Fm203.
