Product Description
Features
Extra Headroom for Hotter Sources
Active circuitry gives high-output instruments extra headroom, helping keep noise and distortion low during studio recording or live mixing sessions.
Flexible Signal Routing
A high-impedance 1/4-inch input, thru output, and balanced XLR connection support routing from a source to a mixer while retaining a pass-through signal.
Practical Signal Controls
Low Cut and Polarity switches, plus Ground Lift on the XLR output, provide controls to adapt connections and signal setup for studio or stage use.
Connect Stereo Sources to Mono Inputs
The Merge switch sums stereo sources to mono at the output, providing a practical mono feed when connecting to a mixer or front-of-house system.
Bonus Laptop and Side Storage
The included charcoal backpack holds laptops up to 15 inches in a padded pocket and adds adjustable straps, a hidden zip pocket, and two open side pockets.
