Thank you for viewing. Please note that I will not negotiate on the price. This is a passive direct box equipped with NORMAL and MELLOW modes. I only tested it once after purchasing it, and it has been stored unused since then. It is almost unused, but it is a used item, so please refrain from purchasing if you are concerned. No returns or refunds. - Model Name: Passive Power D.I. ST - Input/Output Terminals: IN, THRU OUT, L OUT, R OUT - Features: NORMAL, MELLOW mode - Accessories: Box, protective documents The following is from the shopping site: ＜Passive DI that requires no power＞ This DI uses a "transformer," which has recently gained more attention from professional engineers. It delivers raw low frequencies and a three-dimensional high-frequency range. The Passive Power D.I. gives the modern sound a unique analog texture. It is equipped with a "MELLOW" switch to further enhance the transformer's influence. ＜Field-oriented design＞ Conventional passive DIs have a gain loss of about -20dB, and boosting to restore that loss was disadvantageous in terms of noise and sound quality. The Passive Power DI's gain loss is kept to about -8dB, allowing for easy use as a general DI. 104mm(W) x 75mm(D) x 31mm(H), 300g Lightweight and compact design. ＜Easily build a stereo system without complicating your existing equipment＞ ＜Excellent compatibility with stereo output effectors and synthesizers＞
