Ensure virtually any active instrument in your repertoire gets a strong, noise-free signal with the Heritage Audio P DI One, a passive DI box with a custom magnetic transformer and a balanced, transformer-isolated output stage. With the noise-blocking transformer, you can enhance samplers, keys, synths, and more while eliminating RFI and DC-born noise.

The P DI One offers excellent signal integrity and superior noise rejection thanks to its premium circuit components and gold-plated I/O connectors. The DI box provides a -15 dB input pad for overly hot signals and a ground-lift switch for eliminating grounding loops. The enclosure is constructed from durable 14-gauge steel for complete protection of the internal PCB. Along with metal switches, this DI box is built to last, even under intensely rigorous usage. Input and thru jacks are 1/4" and the output is over XLR 3-pin.

Versatile and Pristine

Being a transformer-based unit, its output is isolated from the instrument and there is a further provision for lifting the ground, as well. An additional -15 dB pad switch helps with hotter instruments and even allows speaker outputs to be plugged into the P DI One. A thru parallel connection rounds out the pack, and all I/O jacks are gold plated and isolated from chassis.

Bring Out the True Tone of Every Instrument

The P DI One works best with active circuit instruments like keyboards, synths, drum machines, samplers, and some guitars and basses, when they are required to be plugged into a PA or recording system. By matching the instrument's output level to a typical microphone level, converting it to a balanced signal and minimizing noise, you can be sure you'll achieve the strongest, clearest signal possible.

Passive Design for Minimal Noise

Thanks to its passive, power-free design, the P DI One converts the impedance from high to low and balances the signal using a magnetic transformer that transfers audio while blocking unwanted DC voltage and RFI. This makes it especially effective at eliminating hum and buzz from ground loops while maintaining the tone of your instrument at every stage.

Works in 2019 Subaru Outback!
If you are looking for an engine air filter to fit in your 2019 Subaru Outback then look no further -this one will fit. I tried two others that would not allow me to close the compartment door with the latches. This one slipped in like a hand in a glove.
