{"product_id":"radial-pz-di-active-157264","title":"PZ DI Active","description":"\u003ch3\u003eA DI Designed for Piezo Pickups and Acoustic Instruments in the Radial Range\u003c\/h3\u003e \n\u003cp\u003eThe Radial PZ-DI stands out from conventional direct boxes by focusing on acoustic and orchestral instruments, whose behavior varies greatly depending on the pickup type and load impedance. Within the Radial range, it is positioned as a dedicated solution for \"sensitive\" sources (notably piezo pickups) that can become harsh, thin, or unbalanced when not matched with the appropriate input. The goal is simple: preserve the instrument's character, avoid harshness, and achieve a more musical signal even before any equalization.\u003c\/p\u003e \n\n\u003ch3\u003eWho Is It For and What Are Its Uses? A Direct Box Tailored for Acoustic, Orchestral, and Recording Applications\u003c\/h3\u003e \n\u003cp\u003eThe PZ-DI is aimed at acoustic guitarists, instrumentalists equipped with piezo pickups, amplified orchestral musicians (violin, viola, cello, double bass, etc.), and any setup where a clean and controlled signal needs to be sent to a console or sound system. It is particularly relevant when switching between multiple instruments on stage, when combating body resonances, or when seeking a more natural playing feel in the monitor mix.\u003c\/p\u003e \n\u003cp\u003eIn both studio and live settings, it facilitates gain and dynamic management while offering controls that act directly on the \"source\" (impedance and filtering) rather than compensating later with more drastic equalization.\u003c\/p\u003e \n\n\u003ch3\u003eKey Settings and Design: A More Musical Signal, Easier to Place in the Mix\u003c\/h3\u003e \n\n\u003ch4\u003e3-position Impedance Selector: The Heart of the PZ-DI\u003c\/h4\u003e \n\u003cp\u003eThe 3-position impedance selector is the hallmark of the Radial PZ-DI. By adjusting the input impedance, you adapt the load seen by the pickup to optimize frequency response, dynamics, and playing feel. The \u003cstrong\u003e1M Ohm\u003c\/strong\u003e mode corresponds to the \"classic\" impedance commonly found on active direct boxes. The \u003cstrong\u003e220K Ohm\u003c\/strong\u003e setting is designed to add warmth and a rounder feel, particularly useful with magnetic pickups, offering an approach similar to what one might experience on certain amplifier inputs. Finally, the \u003cstrong\u003e10M Ohm\u003c\/strong\u003e mode aims to compensate for the sometimes overly bright or \"harsh\" character frequently associated with piezo systems, restoring a softer and more natural sound.\u003c\/p\u003e \n\n\u003ch4\u003eVariable High-Pass Filter: Controlling the Lows Without Altering the Tone\u003c\/h4\u003e \n\u003cp\u003eThe variable high-pass filter allows gradual attenuation of low frequencies to reduce resonances and rumble that often complicate amplification of acoustic instruments. It is a very musical tool: you can maintain the foundation of a low instrument (for example, a cello) while tightening the low end, or filter more aggressively for a higher-pitched instrument (for example, a violin) to gain precision and stability. On active instruments, such as some acoustic guitars with onboard preamps, activating this filter can also contribute to a smoother sound better integrated into the mix.\u003c\/p\u003e \n\n\u003ch4\u003eOptimized Internal Power Supply: More Headroom, Less Distortion\u003c\/h4\u003e \n\u003cp\u003eTo improve transient handling and limit distortion, the PZ-DI incorporates a DC power supply that converts phantom power to provide increased headroom. The result: a comfortable dynamic range rated at \u003cstrong\u003e105dB\u003c\/strong\u003e, particularly appreciated on acoustic instruments where attacks (bowing, pizzicato, pick) can be very fast and highly contrasted.\u003c\/p\u003e \n\n\u003ch4\u003ePad, Polarity, Ground Lift: Smart Features for Real-World Situations\u003c\/h4\u003e \n\u003cp\u003eFor high-level sources, such as some active basses or digital keyboards, the \u003cstrong\u003e-15dB pad\u003c\/strong\u003e helps prevent clipping and maintain a clean gain structure. The \u003cstrong\u003e180-degree polarity reverse\u003c\/strong\u003e assists in solving phase issues, especially when combining multiple sources (mic + pickup, stage monitors, bleed). Finally, the \u003cstrong\u003eground lift\u003c\/strong\u003e remains essential for reducing hum caused by ground loops in complex stage environments.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical
