From Pedal to Performance
The Highline is a passive line isolator designed to deliver guitar and amp modelers to the PA system with zero coloration, noise, or distortion. An industry-leading Jensen transformer provides isolation to protect your gear from phantom power, while also delivering a flat frequency response from 10Hz to over 70kHz. The Highline is built to handle the toughest touring environments, with a heavy gauge steel enclosure and switches rated at over 20,000 cycles, so you can depend on it to deliver your sound night after night without fail.

Elevate your tone
The Highline is a line isolator that is specifically designed to address the needs of instrumentalists who use amp modelers, allowing them to seamlessly connect to a PA or a recording system while maintaining their full signal integrity with no added noise or distortion. The Highline features a premium Jensen 1:1 transformer, which retains the full volume level from the pedalboard to the PA, while also providing galvanic isolation that eliminates ground loop noise for a clean and noise-free signal. The balanced output of the Highline allows for long cable runs to the PA, and it also blocks phantom power so it never reaches the pedalboard. The Highline can also accept stereo inputs and sum them down to mono with the use of the Sum switch.
Designed for amp modelers
Guitarists and bassists who use utilize amp modelers on their pedalboard have a unique set of problems: While amp sims can produce line-level outputs, they often still use 1/4" unbalanced connectors that won't support long cable runs without degrading the tone of the instrument, and they are particularly susceptible to noise from ground loops when connected directly to the PA. The Highline addresses these issues by inserting a 1:1 transformer into the signal path, which provides isolation to reduce noise, protects against phantom power, and keeps the signal at line level for direct connection to the PA system.
Input
1/4" input jack to connect to the balanced or unbalanced outputs from amp simulators & guitar pedals.
Sum
Turns the Input and Thru jacks into a passive mixer to sum stereo sources down to mono.
Thru
1/4" output to feed a stage amplifier. Can also be used as a second input if using a stereo source device.
Output
XLR output provides a balanced & isolated signal for feeding the input of a mixer.
Lift
Ground lift switch eliminates hum and buzz from ground loops
