Stereo Di Box Passive

Never we repeat never try to combine two signals into one with a y cable or use a single mono cable.

Stereo di box passive.

To put it simply active boxes require a power supply while passive ones don t. A passive direct box uses a transformer to convert the signal whereas an active direct box has a preamp built into the circuitry. Typical turns ratio is about 500 1 to match a nominal 50 kω signal source such as the magnetic pickup of an electric guitar to a 100 ω input. A passive di unit typically consists of an audio transformer used as a balun.

Thanks to this circuitry active di boxes commonly require phantom power or a nine volt battery. A passive direct box di used in reverse reduced the noise much better than a 1 1 isolation transformer. It employs two world class jensen jt db epc audio transformers to deliver a smooth warm sounding bessel curve reminiscent of the finest vintage gear. Ruler flat from 10hz to 40khz and with virtually zero phase deviation the jdi stereo delivers the natural pure sound of the instrument without artifact.

To put it simply active boxes require a power supply while passive ones don t. A high quality passive direct box that uses 2 proprietary custom made transformers one for each channel for both impedance conversion and isolation. The unit is completely passive and utilizes rolls proprietary audio transformers for superior sound a heavy duty steel chassis was chosen to provide maximum reliability when used in demanding live sound reinforcement applications a variety of inputs are provided including stereo and mono 1 4 in stereo rca and stereo 1 8 in 3. It required an attenuator conversion cables and setting the camcorder audio level to manual.

Passive stereo direct box the radial trim two is a passive direct box designed for use with laptop computers and other consumer type devices where the user has a requirement for a ready access volume control for quick adjustments on stage. The radial jdi stereo is a passive two channel direct box designed to handle extreme signal levels without distortion of any kind. Less commonly a passive di unit may consist of a resistive load with or without capacitor coupling. A passive direct box uses a transformer to convert the signal whereas an active direct box has a preamp built into the circuitry.

One such device that handles all of this beautifully is the radial proav1 a passive direct box with 1 4 rca and 1 8 stereo connectors for instruments tablets ipods and computers that are summed to mono.
