Vancouver, BC (October 1, 2012)—Radial Engineering has introduced the Radial PZ-DI, a special direct box designed to work with acoustic and orchestral instruments, aiming to optimize the input impedance to match the pickup or transducer.

"With bigger and better PA systems in every venue and on every tour, the need to faithfully amplify acoustic instruments has never been greater,” commented Radial president Peter Janis. This has spawned a need for a direct box that is equally capable of adapting to piezo transducers as it is to magnetic pickups. Piezos are particularly problematic due to the squawk and peaks that they produce. The PZ-DI is set to easily overcome these problems and is well equipped to help eliminate feedback and resonance caused by low frequencies along with the interaction between the room acoustics and the PA."

The unit includes a 3-position impedance selector switch that lets users match load with the pickup—options include a 220k-ohm setting to warm up magnetic pickups, a 1 meg-ohm setting to replicate a classic DI box and a super-high 10 meg-ohm setting to eliminate the squawk and peaks that are common with piezo transducers. A variable lo-cut filter reportedly allows users to dial out unwanted low-frequencies. Should the PZ-DI be called upon to interface a high output active bass or digital keyboard, users can engage the -15dB pad. A hi-cut filter is also available on the unit.

The PZ-DI canork double duty as a standard direct box with front panel 1/4" input and thru connectors to interface with an electric bass and the stage amplifier plus XLR out to feed the PA. The PZ-DI employs 48V phantom power with an internal switching supply that elevates the rail voltage while reducing distortion. The PZ-DI is made with 14 gauge steel I-beam construction and is backed with a 3-year transferable warranty.
