Soundelux Model U195
User Manual

Introduction

Soundelux USA U195 is custom built, hand made cardioid patterned, phantom powered,
large diaphragm FET microphone. In designing the U195, David Bock set out to create an
extreme value in studio mics that could satisfy a wide range of demands for highly experienced
engineers that own many more expensive microphones, yet need additional mics within a
budget. It delivers superb results on lead vocal tracks as well as in instrument and guitar amp
use, providing remarkable fullness and presence with exceptionally low background noise.

Description

Soundelux USA U195 is a FET amplifier cardioid microphone powered by P48 phantom voltage. The microphone's
audio output is standard male XLR3, with positive excitation of the diaphragm at the front of the mic resulting
in a positive voltage at the output XLR's pin 2. Audio output is fully transformer balanced.

Additional Circuit Notes

The U195 circuitry is based on an optimized version of the venerable U87, with a much larger transformer and
more sophisticated bias circuitry to eliminate the classic "honk" midrange emphasis of the U87. In addition it
offers the user unrivaled control of the amplifier, providing voltage divider pad function (rather than a capacitive
pad), active low cut function, and a unique "fat/norm" switch which allows a gentle low mid/bass EQ in the
circuit. This "fat" switch provides a greater sense of impact and power, as well as conveying a warm, intimate
sound.

Getting Started

It is recommended that the user place the mic in its shockmount on a stand and connect all the cables before
using the unit. This mic (especially in "fat" mode) is very sensitive to low frequencies below 20 Hz, and the mic
may be sensitive to rumble, HVAC, and other sub-sonic activity that were previously unapparent. Any combination
of switch settings may be used for a nearly infinite variety of tonal variations.

Power Supply and Cable

Soundelux U195 is powered by P48 phantom power. Operation with less than 40V phantom may result in
compromised performance. For more detail on phantom powering, please see DIN 45 596/IEC268-15A. Remember
to use good quality as-new cables whenever possible, as older cables with internally frayed shield wires often
result in poor performance with phantom powered mics.
