Balanced-to-Single-Ended Signal Conversion
The ddHiFi DJ30SE doesn't simply short the negative balanced channel to ground, such improper wiring would raise load risk and damage your audio devices.
Its precise circuit taps the positive left and right signals from the 4.4mm balanced output and routes return current to the native ground pin of the 4.4mm port. It utilizes half of the balanced output power to deliver a clean single-ended signal.
*Note: The DJ30SE cannot work with players whose 4.4mm jack lacks a ground pin, including Sony music players with 4.4mm balanced output.
Ultra-Slim Form
Developed based on the DJ44L, the DJ30SE features a lowered overall profile. When paired with headphone cables equipped with 3.5mm straight plugs, it stays compact and reduces bulk.
One-Piece Metal Construction
The DJ30SE adopts aviation-grade aluminum alloy for its shell, crafted via precision CNC machining. It comes with a thickened anodized surface finish, boasting high hardness and excellent wear resistance. With full-body shielding, it effectively blocks external electromagnetic interference and minimizes sound quality loss caused by adapter conversion.
