Know before you buy
The converter maintains a consistent load on your amplifier, which is essential for preventing damage to sensitive tube amps. By using high-quality non-inductive resistors, it safely manages high-wattage signals before they reach your headphones, ensuring both components operate within safe parameters.
The bypass switch is designed for low-sensitivity headphones that may require more direct signal flow. It allows you to optimize the performance of your specific headphone model by bypassing the standard resistive network when necessary.
No, this is a passive device. It draws all necessary power directly from your existing speaker amplifier, meaning you do not need to plug the converter box into a wall outlet.
You should select the wattage option that matches or exceeds the maximum power output of your speaker amplifier. If you are unsure, check your amplifier's manual for its peak power rating to ensure the converter is configured correctly for your setup.
Yes, the unit is custom-built to your specifications. You can choose from various input options like Speakon or Cardas posts, and output configurations including dual 4-pin XLR or 1/4" jacks to match your existing cables.
No, the device is a purely analog passive circuit. It introduces 0.0 ms of latency, ensuring your audio remains perfectly synchronized with no digital processing delays.
