Radial Twin Iso

Equipped with the world's finest Jensen Audio Transformers, the Radial Twin-Iso is a no-excuse problem solver that provides exceptional audio performance while eliminating ground loops. It features 2 +4dB line-level floating channels with XLR input and output connectors for easy interfacing. Nickel-laminated Jensen JT-11P1 isolation transformers and insulated XLRs provide 100% isolation. As a unity-gain device it boasts 10Hz–40kHz response and balanced, 10kohm input impedance. Jensens do not introduce problems such as phase shift or group delay, which can cause bass to sound muddy and indistinct. This is of utmost importance when interfacing advanced line array systems where maintaining phase relationships is paramount to achieving the controlled dispersion pattern. Jensen Transformers are legendary for their warm Bessel curve and for their ability to handle transients without overload or ringing.
