J1 Мini – Mono DI Box (J-FET, Class A)

• For critical recording, high-impedance sources.

The J1mini elevates transparency to a higher standard. Discrete J-FET transistors operating in Class A deliver exceptional clarity and the finest low-level detail retrieval in our product line.

• Sound Quality Characteristics
• Spectral Uniformity: Ultra-low THD of 0.0009% @ 0 dBu ensures zero added harmonic coloration. Tonal balance remains perfectly preserved across the frequency spectrum.
• Transient Response: Extended bandwidth to 200 kHz captures the highest-frequency transient information, resulting in precise attack reproduction and natural percussion shimmer.
• Dynamics and Distortion: J-FET input stage delivers distortion levels 3–6 times lower than D-series, with maximum headroom of +34 dBu (PAD on). Play with complete dynamic freedom without worry.
• Pianissimo Clarity: Noise floor of −110 dBu (10 dB better than D-series) ensures that low-level ambient detail, reverb tails, and subtle playing techniques emerge with pristine clarity. Perfect for mastering-grade recording.
• Ambience Reproduction: Superior noise performance and ultra-low distortion combine to preserve reverberation and spatial information with studio-reference quality.
• High-Impedance Source Compatibility: Input impedance >4.7 MΩ provides optimal loading for passive pickups, vintage keyboards, and modular synth outputs without tone sucking.
