INPUT PANEL

1. INPUT: ¼” hi-Z input used to connect the instrument to the PZ-DI.

2. THRU: ¼” throughput used to feed an on-stage instrument ampli-

ﬁ er.

3. LOAD: 3-position switch lets you adjust the input impedance to

optimize the load for the type of pickup being used. Set to 220k

ohm for magnetic pickups, 10 meg-ohm for piezo transducers

and 1 meg-ohm to replicate traditional DIs.

4. PAD: Reduces the input sensitivity by -15dB enabling the PZ-DI

to be used with high output instruments such as active basses

or keyboards.

5. LO-CUT: Variable high-pass ﬁ lter is used to remove unwanted

resonance and size the instrument to suit. Variable from 5Hz to

500Hz.

6. HI-CUT: Used to warm up the sound of active instruments that

often contain excessive high frequencies.

7. BOOK-END DESIGN: Creates protective zone around con-

nectors, switches and potentiometers to prevent damage.

OUTPUT PANEL

8. NO SLIP PAD: Provides electrical & mechanical isolation while

keeping the PZ-DI from sliding around on busy stages.

9. XLR OUT: Balanced low impedance output used to connect the

PZ-DI to the mixing console. Allows long cable runs in excess of

100 meters (300 feet) without noise.

10. PHASE: 180° polarity reverse toggles pin-2 and pin-3 at the XLR

output. Used to tame acoustic hot spots on stage and help reduce

resonant feedback.

11. LIFT: Ground lift switch disconnects the ground from the audio

signal path and helps eliminate hum and buzz caused by ground

loops.

12. 48V: Provides visual status of 48V phantom power. When the

LED is on, the PZ-DI is being fed 48 volts from the console.

13. STEEL CONSTRUCTION: Radial ‘standard’ heavy-duty 14-gauge

steel construction for added durability and extra shielding against

electromagnetic ﬁ elds. The baked enamel ﬁ nish keeps your

Radial PZ-DI looking great for years!
