The design begins with a rugged extruded aluminum enclosure and steel slide-in inner tray with recessed zones at each end to protect the switches and connectors. At one end, left and right ¼” instrument inputs and thru-puts are wired in parallel with a handy 3.5mm mini TRS for laptops and tablets. A -15dB pad decreases input sensitivity for greater signal handling when interfacing line level sources. At the other end, two XLR male outputs with ground lift makes for easy connection.

Inside, two high-performance Jensen JT-DB-EPC transformers provide galvanic isolation as they passively lower the impedance and perform the balancing. A high 140 kΩ input impedance reduces loading, enabling low-output instruments such as a vintage Fender® bass to be connected without losing tone. As hi-Z instruments are particularly sensitive to noise, internal Faraday shielding protects against interference from RF. An external MuMETAL® can further protects the sensitive internal workings to ensure a quiet interference-free performance even when surrounded by magnetic fields from amplifiers, power supplies and stage light dimmers.

With over +22 dB of signal handling capacity, the Concert-2 direct box gracefully handles extreme signals such as those produced by digital pianos while producing a warm Bessel response that is often referred to as ‘vintage’ sounding. These features combine to make the Concert-2 the ideal choice for studio or live use.
