Radial Engineering JDI

Description

<h1 style="text-align: justify;"><strong>Radial Engineering's JDI</strong> is a compact <strong>passive DI BOX</strong> that uses a Jensen audio transformer, adapting impedance and balancing your instruments' audio signal.</h1><p><strong><img align="" height="" src="/filer/sharing/1765465002/11091/" title="Radial JDI is a compact passive DI BOX that uses a Jensen audio transformer, adapting impedance and balancing your instruments' audio signal." width=""></strong></p><h2><strong>Radial JDI Controls and Connections</strong></h2><ul style="text-align: justify;">    <li><strong>-15 dB PAD</strong>: reduces input sensitivity by 15 dB</li>    <li><strong>MERGE</strong>: turns the input and thru jacks into a passive mixer to sum stereo signals to mono.</li>    <li><strong>INPUT</strong>: ¼” input jack for instruments</li>    <li><strong>THRU</strong>: the ¼” thru jack passes the instrument signal to the amplifier.

JDI uses the Jensen JT-DB-EPC audio transformer which, thanks to the integrated analog Bessel filter, with its typical warm and soft sound, reproduces the natural tone of the instrument free of artifacts. Thanks to its passive design without power, it converts the signal impedance from high to low and handles signal balancing. This makes JDI particularly useful in eliminating hum caused by ground loops. In addition, thanks to the “Speaker” button, by connecting your speaker output to the JDI, you can emulate a 12” cone that allows you to connect in parallel to the input of a mixer.</p><p style="text-align: justify;"><img align="" height="" src="/filer/sharing/1765465146/11092/" title="Radial JDI is a passive direct box designed to handle extreme signal levels without any distortion. JDI uses the Jensen JT-DB-EPC audio transformer." width=""></p><h2 style="text-align: justify;"><strong>Radial JDI Features</strong></h2><ul style="text-align: justify;">    <li>Jensen JT-DB-EPC transformer</li>    <li>Excellent signal handling</li>    <li>Audio circuit: Passive, transformer-based</li>    <li>Number of channels: Single channel (mono)</li>    <li>Frequency response: 20 Hz to 20 kHz (± 0.2 dB)</li>    <li>Dynamic range: 135dB</li>    <li>Total Harmonic Distortion: 0.05% from 20 Hz to 20 kHz (-10 dB)</li>    <li>Phase deviation: 0.3° at 100 Hz; 3° at 20Hz</li>    <li>Input impedance: 140k Ohm, unbalanced</li>    <li>Output impedance: 150 Ohm, balanced</li>    <li>Maximum input: +21dB from 20Hz to 20kHz</li>    <li>Input Pad, Mono Sum, 180° polarity inversion, Ground lift, Speaker filter</li>    <li>Construction: steel shell</li>    <li>Finish: durable powder coat</li>    <li>Dimensions and weight: 127x84.1x45.5mm; 703g.</li>    <li>Power: passive, no power required</li></ul>
