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.

Safety
• CAUTION: Shock Hazard: Do not open microphone when connected to
power source. No user serviceable parts inside. Refer failed units to
qualified service personnel.
• VORTICHT: Shock gefar: Bitte nicht daf mikrofon offen wenn es
eingeschaltet ist einen stoppkontakt.
• Keine zu wartenden Teile im Inneren. Beziehen gescheitert Einheiten
qualifiziertem Service-Personal.
• ATTENCIONE: Choc hazard: N’ouvrez pas le microphone quand il y a
un connectionne avec un source d’electricity. Aucune pièce réparable
par l’utilisateur. Référer unités échoué à un personnel qualifié.
• ATTEZIONE: Riscchio di scossa: Non aprire il microfono quando e
attacato al’eletricita. Non contiene parti riparabili. Riferimento unità
riusciti a personale qualificato.
• Read the instructions.
• Keep these instructions.
• Heed all warnings.
• Follow all instructions
• Do not use this apparatus near water.
• Clean only with dry cloth.
• Do not block any ventilation openings. Install in accordance with the
manufacturer’s instructions.
• Do not install near any heat source such as radiators, heat registers,
stoves, or other apparatus (including amplifiers) that produce heat.
• Do not defeat the safety purpose of the polarized or grounding-type
plug. A polarized plug has two blades with one wider than the other.
• Protect the power cord from being walked on or pinched particularly
at plugs, convenience receptacles, and the point where they exit
from the apparatus.
• Only use with attachments/accessories specified by the
manufacturer.
• Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way, such
as power-supply cord or plug is damaged, liquid has been spilled
or objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has been
dropped.
