Automatically installs without the need of a driver

Built-in headphone amplifier for monitoring

Equipped with Jensen transformer

Eliminates buzz and hum from ground loops

Virtually zero phase and harmonic distortion

Active 48-Volt phantom powered direct box -15dB pad 180 degree polarity reverse Merge function to mix 2 signals to mono 80Hz high-pass rumble filter Ground lift Welded I-beam construction Minimal power draw with high rail voltage Will not choke when driven hard Low intermodulation distortion

The J48 is capable of peak transients to 9 volts without choking

The result is lower harmonic distortion, half the inter-modulation distortion and significantly improved dynamics over other DIs

The Radial JPC is a stereo direct box that has been specifically designed for use with computer sound cards and other consumer electronic products to allow these to be connected to a professional sound system. It is unique in that it combines the advantages of transformer-isolated inputs with an active drive circuit, giving you the 'best of both worlds' in a compact and extremely flexible package. Transformer coupled inputs have the unique advantage of isolating the 'source' from the '

The JPC features two active 48V phantom powered channels in a compact, rugged enclosure

It combines an active drive circuit, for long cable runs, with transformer isolated inputs to eliminate hum and buzz caused by ground loops
