Radial JPC MK3 Stereo PC DI Box Isloated In/Active Out
Active Direct Box for Laptop Computers
The JPC is an analog stereo interface designed to help solve the hum and buzz problems commonly associated with connecting a computer or consumer playback device to an audio system.
Hybrid circuit for low noise
The JPC is a stereo direct box that is easy to use with practically any consumer electronic device. It utilizes active buffers and transformer isolation to create a hybrid circuit that blocks ground loops and reduces system noise, along with AC blocking capacitors to prevent any audio system noise from bleeding back into the computer. The choice of ¼”, RCA and 3.5mm input connectors make it easy to interface with all types of unbalanced audio sources such as computers, smartphones, and tablets, and the outputs are XLR balanced mic level to feed snake systems and PAs. Powering the JPC is accomplished via 48V phantom from a mixing console, allowing the JPC to be used in concert environments without requiring an external power supply.
-10dB Pad: Reduces the input level from extra loud sources to prevent overload distortion. When depressed, the pad is inserted on both channels.
48V LED: Individual LEDs let you know that phantom power is active on left and right channels.
1/4″ Inputs: Stereo inputs accommodate drum machines, samplers and keyboards and are wired in parallel with RCA and 3.5mm (1/8″ TRS) connectors.
3.5mm TRS Input: Wired stereo for easy interface with laptops PCs and iPods. TRS connection follows convention with tip-left, ring right and sleeve-common ground.
RCA Inputs: Ideally suited for connecting DVD/CD players and video machines to the JPC. RCA thru-puts add extra flexibility to allow aconnectivity to other equipment.
