aerobics instructors (the QE model is water resistant and is optimized for aero-
bics use and high-humidity environments). Manufactured with extreme care and
the highest quality components, they deliver an exceptionally clear, articulate
sound, with superior rejection of background noise.The QE/QV Headset along
with the PM4 phantom power adaptor are well-suited for any vocal amplifying
situation.
In this manual, you’ll find a more detailed description of the features of your
QE/QV Headset, as well as instructions for using your QE/QV Headset with the
PM4 phantom power adaptor, and complete specifications.You’ll also find a war-
ranty card enclosed—don’t forget to fill it out and mail it in! This will enable you

FEATURES
The Samson QE/QV Headset utilizes state-of-the-art headset microphone tech-
nology and is engineered to the finest detail. Here are some of its main features:
•Lightweight, low visibility design for unobtrusive use.
•High quality electret condenser element delivers high output and exceptional
sound quality.
•Full range frequency response for clear, crisp audio.The QV Headset is vir-
tually flat to 10kHz, while the QE Headset utilizes a midrange “presence”
peak for optimum reproduction of speech.
•Tight hypercardioid polar pattern (in the QV) and bi-directional noise cancel-
lation design (in the QE) reduces background noise, minimizes feedback
problems and effectively rejects signals not originating directly in front of the
mic capsule.
•QE Headset includes internal radio frequency (RF) suppression, making it
suitable for use in high-RF urban areas.

FEATURES
•Microphones are molded to high quality gooseneck booms constructed of
brass over stainless steel wire with matt black polyurethane covering.
Compliant molding reduces microphone handling noise, and the booms
bend smoothly, hold their shape and are rated to withstand over a thousand
90°bends without degrading.
•Both the QV and QE Headsets are moisture protected, and the QE is water
resistant, making it the microphone of choice for aerobics instruction or in
other high-humidity environments.
•Both the QV and QE Headset microphones terminate with a P3 connector
which plugs into to the PM4 phantom power adaptor.
•The PM4 phantom power adaptor is used to supply the QE/QV microphone
with phantom power, while transforming the impedance from high to low to
compensate for longer cable runs.
As shown in the illustrations below, the correct way to wear your QE/QV
Headset is over the ears, as you would wear a pair of eyeglasses.
The QE/QV Headset is specially designed to be used up close, so be sure to
adjust the microphone to be directly in front of your lips, as shown in these illustra-
tions. Although it generates significantly less handling noise than most other head-
sets (due to its compliant molding), it should be left in one position during use.To
avoid feedback problems, take care not to cover the mic capsule with your hand.

USING YOUR QE/QV HEADSET
Slide the foam windscreen over the microphone ,as shown in the illustration on
the previous page, to eliminate wind noise.
The PM4 phantom power adaptor with its special interface, enables a mixer to
provide phantom power to condenser, piezo or electric microphones.The PM4
converts high impedance (50 k –10meg ohm) to low impedance (600 ohms)
allowing long cable runs without noise and gain loss.
Connect the P3 plug from your QE/QV Headset into the locking input of the
PM4. Connect an XLR cable from the PM4 to the input of your mixer. Clip the
PM4 to your belt loop or some other part of your clothing, as in the photos on
the box cover, as not to cause strain by pulling on the wire coming from the
headset.You should also select a thin, lightweight XLR cable for this interface.
Every microphone has a characteristic polar pattern that determines how well
it accepts or rejects signals coming from various areas around the microphone.
A type of design which is particularly good at rejecting background noise is the
bi-directional polar pattern uti-
lized by the QE Headset, as
shown in the illustration on the
left.
