Whirlwind ISO 1 1-Channel Line Level Isolator, 20Hz-20kHz Frequency Response, 1/4" TRS/XLR Jacks, Ground Lift Switch

Take your audio experience to the next level with the Whirlwind ISO 1 1-Channel Line Level Isolator. This premium quality line level audio transformer device is expertly designed to provide transformer isolation and ground lifting, effectively eliminating buzz and hum problems that can interfere with your sound quality.

Ideal for use on console outputs, amplifier input feeds, or any line level signal, the ISO 1 is a versatile solution for your audio needs. It also functions as a balancer, seamlessly converting between balanced XLR and unbalanced 1/4" signals, making it a valuable addition to any audio setup.

At the heart of the ISO 1 is Whirlwind's TRSP-600L transformer, which boasts a frequency response of +/-1 dB from 20 to 20 kHz at +20 dBm input level. This ensures a consistent, high-quality audio output across a wide frequency range.

The ISO 1 features two input and output connectors, XLR or 1/4" TRS jack (Tip = Pin 2, Ring = Pin 3), providing flexibility for connection to line level signals. These input jacks are connected in parallel with each other, as are the output jacks, but it's recommended to use only one connector on each side at a time for optimal performance.

A standout feature of the ISO 1 is its Ground Lift Switch. This switch allows you to disconnect the ground between the input connectors and the output connectors when set to the LFT position, and reconnects the ground when switched to the GND position. This feature provides additional control over your audio output, ensuring the best possible sound quality.

In summary, the Whirlwind ISO 1 1-Channel Line Level Isolator is a high-quality, versatile audio device that offers superior transformer isolation, ground lifting, and signal balancing capabilities. It's an essential tool for any audio enthusiast or professional looking to enhance their sound quality.
