JDI Passive Direct Box
The JDI employs a Jensen audio transformer as the engine. Jensen transformers are legendary in their ability to gracefully handle transients while delivering a smooth, warm sounding Bessel curve. Ruler flat from 10Hz to 40kHz and with virtually zero phase deviation, the JDI delivers the natural, pure sound of the instrument without artifact. Features include input and throughput 1/4” connectors, -15dB input pad, ground lift, and 180 degree polarity reverse. A secondary circuit is added for direct interfacing with high output devices such as guitar or bass amp loudspeakers. And a unique merge function allows stereo sources such as keyboards to be summed mono. The steel casing resists noise-causing electromagnetic pollution and the transformer’s sensitive inner workings are further protected from magnetic fields with a mu-metal can. This ensures the signal transfer is quiet and free from hum.
