This is for 1- New Radial PZDI Active Direct Box for acoustic/orchestral instruments.  The Radial PZ-DI is a unique direct box that is specifically designed for acoustic and orchestral instruments. Unlike most direct boxes that are limited to a 'one size fits all' design, the PZ-DI lets you properly match the input impedance to the source to optimize the frequency response, dynamics and feel so that no matter what type of pickup you employ, you will enjoy smoother, more musically pleasing results.

 

The design begins with a 3-position load adjustment switch: The 1 meg-ohm position delivers the classic impedance found on most active DI boxes. The 220k-ohm setting warms up the tone of a magnetic pickup to give you the feel and tone as if connected to a tube amplifier. The ultra-high 10 meg-ohm impedance is used to compensate for the harsh, squawky tone that usually plagues piezo-equipped instruments. This is followed by a fully variable high-pass filter that lets you 'size the instrument' by gently rolling off bass frequencies to eliminate unwanted resonance. You could for instance, retain the low frequencies on a cello or increase the cut-off point to better suit a violin. For active instruments such as acoustic guitars that incorporate a battery powered preamp, you can engage a low-pass filter to gently soften the hard edge for a smoother more natural tone.

 

To maximize signal handling and reduce distortion, the PZ-DI incorporates an innovative DC to DC switching supply that converts the phantom power to deliver extra headroom. This provides ample dynamic range for acoustic instruments. Should an extra loud source such as an active bass or digital keyboard be encountered, simply activate the -15dB pad to satisfy the situation. Other problem solvers include a 180° polarity reverse switch to tame hot spots on stage that can cause feedback and a ground lift switch to help eliminate hum and buzz caused by ground loops.

 

The Radial PZ-DI is a ground breaking direct box that can instantly adapt to all types of pickups so that you can enjoy the full frequency response and dynamics of an orchestral string instrument, smooth-out the peaks of bluegrass fiddle, banjo or mandolin, split off a bass guitar without excessive loading, or naturally amplify an acoustic guitar without the usual tone-altering effects.

Applications:

 

Using the PZ-DI with a piezo

Piezo pickups often sound harsh and unnatural. The PZ-DI solves the problem with a 10 meg-ohm input impedance that extends the frequency response and smoothes out the peaky edges. Adjust the low-cut filter to size the instrument and reduce unwanted resonance.

 

Using the PZ-DI with active acoustics

The convenience of a built-in pickup and battery powered preamp makes it easy to plug-in and play. But with less than ideal electronics, these instruments end to sound brittle and unnatural. The PZ-DI helps with a low-pass filter that gently smoothes the top end plus a variable low-cut filter to eliminate resonance.

 

Using the PZ-DI with a magnetic pickup

Optimize the tone of the bass by setting the load to 220k-ohm. This produces a warmer tone and natural feel that is particularly useful when recording or when preparing to Reamp. When touring with low-output vintage instruments, set the impedance to 1 meg-ohm to reduce the load.
