Description

The Radial PZ-DI is an active direct box that has been optimized to work with the various types of pickups used on acoustic and orchestral instruments in a concert touring environment. The design begins with 3-position impedance selector to match the pickup: a 220k-ohm setting warms up magnetic pickups, a 1 meg-ohm setting replicates a classic DI box, and a 10 meg-ohm setting is used to eliminate the squawk and peaks that are common with piezo transducers. A variable high-pass fi lter lets you eliminate low-frequency resonance to improve clarity while reducing vibration borne feedback. A signal reducing -15dB pad and low-pass fi lter can also be engaged to gently smooth the over aggressive top-end produced by many active instruments. The PZ-DI is fully capable to work double duty as a standard direct box with front panel ¼” input and thru connectors to interface with an electric bass and the stage amplifi er plus XLR out to feed the PA. The PZ-DI employs 48V phantom power with an innovative internal switching supply that at once elevates the rail voltage while reducing distortion of all types to deliver a smooth, natural tone with the same perfectly cascading even harmonics normally found on high-end studio preamps.
