Product DescriptionThe Radial Engineering Twin-Iso is a two-channel Jensen Transformer equipped isolation box designed specifically for use in concert settings to eliminate noise caused by ground loops. Often, in concert settings, when interfacing equipment such as two or more consoles together, the common-mode noise caused by stray fields and differing ground reference voltages will cause hum and buzz commonly known as ground loops. This is difficult if not impossible to control especially when confronted with multiple acts during festivals where each will have their own console and is more challenging when interfacing the front of house system with remote delayed towers or broadcast trucks that are often fed with a different AC source. 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 two +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. Jenen’sdo 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 are paramount to achieving the controlled dispersion pattern. Jensen Transformers are legendary for their warm Bessel curve and in their ability to handle transients without overload or ringing. As a unity-gain device, the Radial Twin-Iso boasts an amazing 10Hz to 40kHz response for natural uncolored sound for ‘mirror-like audio picture quality’. To allow long cable runs with minimal loading, the Twin-Iso features balanced, 10k-Ohm input impedance. This assures optimum performance when the Radial Twin-Iso is positioned near the input of the receiving device.
