Oxygen Buffer

This switch is used to select the operating mode of the Buffer.

1. For the MONO operating mode, the position of the switch does not matter.
2. For the Splitter operating mode, set the switch to the Splitter position.
3. For the Dual or Stereo operating mode, set the switch to the Dual position.

The diagram of the functioning of the different operating modes can be found in the manual.

It is recommended that the Oxygen Buffer be the first piece of equipment in your chain, right after the guitar. In this position, it will bring the greatest benefits to your signal.

However, it is important to note that the Buffer should be positioned after Fuzz effects and Vintage Wah pedals, as these devices can alter the tone when they are not in direct contact with the guitar.

Additionally, other positions that bring benefits to the signal include:

1. After the Send of a Tube Amplifier with a Tube Effects Loop.
2. As the last device in the effects chain.

The guitar is known to have a high output impedance. With this high impedance, even a small capacitance present in the cable can create a filter that starts to attenuate the audible high frequencies, resulting in a loss of brightness in the tone.

By using the Oxygen Buffer, it has the ability to convert the guitar’s high impedance to a low impedance output. Once the signal is at low impedance, the filter formed begins to act in an ultra-high frequency region, well beyond the audible frequencies. This allows the signal to maintain all its integrity, without suffering brightness loss due to the filter formed between the guitar and the cable, resulting in a more faithful, clean, and accurate tone.

Additionally, another benefit of the low output impedance is the improvement in the impedance matching between the guitar and its effects/amplifier. This allows 100% of the signal to be transmitted to the effect/amplifier, whereas a signal with high impedance suffers losses. This improvement in impedance matching contributes to a complete signal transmission, ensuring a reproduction with more punch and dynamic tone of the guitar.

You can find the entire update procedure for your controller in the video (Hyperlink). Additionally, detailed instructions are also available in the product manual.

If the power in your city went out during the update of your controller and now you’re facing a white screen, don’t worry. There’s a recovery procedure that will solve this problem:

1. Turn off the controller, disconnect the USB cable, and close the update program.
2. Hold down Footswitch 1 and turn on the controller. The screen will remain white at this point.
3. Once the controller is powered on, release Footswitch 1. Then, connect the USB cable and reopen the update program.
4. Select the “.bin” update file and click on “Firmware Update” in the update program.
5. Wait until the update process is completed. Once it’s finished, you can continue using your controller normally.

This procedure will fix the white screen and allow you to resume using your controller without issues.
