Hybrid Low-Noise Circuit

The Radial JPC uses a combination of active buffering and transformer isolation to provide a low-noise connection between consumer devices and professional audio equipment.

The active buffer circuit helps drive the audio signal effectively, while transformer isolation helps prevent ground-loop problems that can introduce unwanted hum and buzz into the sound system.

The JPC also incorporates AC blocking capacitors to help prevent unwanted noise from travelling back into the connected computer or playback device.

Multiple Input Connections

The JPC provides multiple input options for connecting different types of unbalanced audio sources.

The 1/4-inch, RCA, and 3.5mm inputs allow the JPC to work with laptops, computers, smartphones, tablets, DJ equipment, CD players, and other consumer playback devices.

This flexible connectivity makes the JPC suitable for professional sound engineers and AV technicians working with different audio sources.

Balanced XLR Outputs

The JPC converts the connected unbalanced audio source into balanced microphone-level XLR outputs.

These outputs can be connected directly to professional mixing consoles, stage snakes, PA systems, and other professional audio equipment.

The balanced output configuration makes the JPC suitable for both live sound environments and installed audio systems.

Transformer Isolation for Noise Reduction

Computers and consumer electronic devices can often introduce unwanted electrical noise into professional sound systems. The JPC uses transformer isolation to help separate the source device from the PA system and reduce unwanted ground-loop currents.

This makes it especially useful when connecting laptops and other electronic playback devices to professional audio systems.

48V Phantom Power

The Radial JPC is powered using 48V phantom power from a mixing console. This eliminates the need for a separate external power supply and makes the unit convenient for live sound and concert applications.

Simply connect the JPC to a compatible mixing console or audio system providing phantom power for convenient operation.

Applications

The Radial JPC is suitable for a wide range of professional audio applications, including:

• Laptop audio connections
• Computer-based playback systems
• DJ setups
• Live concerts
• Stage sound systems
• Professional PA systems
• Conference rooms
• Corporate presentations
• Classrooms
• Audio-video installations
• Smartphone audio playback

• CD and media players
• Recording and production environments
• House of worship applications
• Event production
• Broadcast and AV systems

Using the JPC with a Computer

The JPC is particularly useful when connecting a laptop or computer to a professional PA system. Computers can sometimes introduce electrical noise, hum, and buzz into an audio system.

The JPC’s combination of active drive circuitry and transformer isolation helps reduce these unwanted noise issues and provides a clean interface between the computer and professional sound equipment.

Using the JPC with a DJ Setup

The JPC is suitable for DJ systems using digital audio files, computers, CD players, and other playback devices. Its transformer-isolated design helps separate the source device from the PA system and reduce unwanted ground-loop noise.

The balanced XLR outputs allow the audio signal to be easily connected to a professional mixing console or PA system.

Using the JPC with a Phone or Tablet

The integrated 3.5mm TRS stereo input makes it easy to connect smartphones, tablets, and other portable playback devices.

The JPC converts the unbalanced audio signal into balanced microphone-level XLR outputs, allowing portable devices to be connected to professional audio consoles and PA systems.

Professional Audio Performance

The Radial JPC is designed for situations where reliable and clean audio connectivity is required. Its active circuitry provides effective signal buffering, while transformer isolation helps protect the audio system from common ground-loop problems.

The combination of flexible inputs, balanced outputs, active circuitry, and phantom-powered operation makes the JPC a versatile solution for professional audio applications.
