imgVancouver, BC (November 29, 2012)—Radial Engineering has released its latest direct box, the Radial PZ-DI, designed to work with all types of acoustic and orchestral instruments by reportedly optimizing 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 “In the past, the sound was masked. Today, you hear every nuance. 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 DI offers a 3-position impedance selector switch that lets users match load with the pickup. This includes a 220k-ohm setting to warm up magnetic pickups, a 1 meg-ohm setting to replicate a classic DI box and a 10 meg-ohm setting to reportedly eliminate the squawk and peaks that are common with piezo transducers. Aiming to eliminate resonance and modulation between instruments, a variable lo-cut filter lets users dial out unwanted low-frequencies. The PZ-DI can interface a high output active bass or digital keyboard by engaging its -15dB pad. A hi-cut filter can also be engaged to smooth out aggressive top-end.

The PZ-DI can be used 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.
