The Radial Engineering Highline is a passive line isolator designed for guitarists and bassists using amp and cabinet modelers in live and studio settings. Featuring a Jensen 1:1 transformer, the Highline maintains signal integrity, eliminates ground loop noise, and provides a balanced output for seamless connection to a PA or recording system.
Designed for modern instrumentalists, the Highline ensures that long cable runs do not degrade tone, while also blocking phantom power to protect sensitive pedalboard equipment. The Sum switch allows stereo inputs to be summed to mono, offering flexibility for various signal routing needs. Housed in a rugged steel chassis, the Highline is built for reliable performance in demanding touring environments.

Applications
Connect Your Amp Sim to the PA
The Highline allows you to send the signal from your guitar amp sim right to the PA while retaining the signal level and sound quality. The transformer inside provides isolation to reduce noise and protects your gear from accidental phantom power activation.
Sum a Stereo Amp Sim to Mono
The Highline can also be configured to accept a stereo signal and sum both channels to the XLR output, so you don't have to reconfigure any of your presets when channel space is limited at the PA. Just engage the sum switch, and you can use the Thru jack as a second input.
Use the Thru to Monitor Locally
When using a mono source device with the Highline, you can take the Thru output to a stage amplifier for local monitoring, while the XLR output feeds the PA system.
