It allows you to connect seamlessly to a PA or recording system while preserving full signal integrity, with no added noise or distortion. The Highline is equipped with premium Jensen 1:1 transformers that maintain maximum volume level between your pedalboard and the PA, while providing galvanic isolation that eliminates ground loop noise for a clean, noise-free signal. The Highline Stereo’s balanced outputs let you use long cable runs to the PA, and the unit also blocks phantom power so it never reaches the pedalboard. The Highline Stereo can be easily reconfigured for multiple setups using two summing switches: these let you connect to the PA or your stage monitors in stereo or mono.
Designed for amp modelers!
Guitarists and bassists who use amp modelers on their pedalboards face a unique set of challenges: although amp simulators can produce line-level outputs, they often use unbalanced 6.35 mm (1/4 in) connectors that don’t handle long cables without degrading the instrument’s tone, and they are particularly susceptible to ground loop noise when connected directly to the PA. The Highline Stereo solves these issues by inserting Jensen 1:1 transformers in the signal path, which provide isolation to reduce noise, protect against phantom power, and ensure audio signals remain at line level for a direct connection to the sound system.
SUM switches for added versatility!
The Thru Sum switch merges the two Thru outputs, allowing you to hear both sides of your stereo signal through a single amplifier while still feeding the left and right channels separately to the PA.
The XLR Sum switch merges the two XLR outputs, letting you send a mono signal to the PA when extra channels are scarce. This lets you change your outputs from gig to gig without having to reconfigure your pedalboard settings.
