INTRODUCTION
Thank you for your purchasing the RPQ160 Parametric Equalizer. The RPQ160
uses T filters for equalization circuits to avoid the complexity and distortion of
state-variable filters. The RPQ160 is a four-band parametric equalizer designed
for years of reliable use. Please read this manual carefully to get the best results
from your RPQ160.
INSPECTION
1. Unpack and inspect the RPQ160 box and package.
If obvious physical damage is noticed, contact the carrier immediately to make a
damage claim. We suggest saving the shipping carton and packing materials for
safely transporting the unit in the future.
