Samson Q7x Manuel utilisateur
OWNER'S MANUAL
Thank you for purchasing the Samson Q7x Professional Dynamic Vocal Microphone. The Q7x microphone brings a high level of accuracy and
clarity to your audio performance and vocal miking applications.
The Q7x is a hand held dynamic microphone that excels both on the stage and in the recording studio. Thanks to its neodymium magnet and
lightweight diaphragm, the Q7x provides a linear frequency response for superior reproduction, with the capability to withstand high sound
pressure levels. It employs a supercardioid pattern to reduce feedback as well as a shock-mounted element that minimizes handling noise and
provides additional protection.
With proper care and maintenance, your microphone will operate trouble-free for many years. Should your microphone ever require servicing, a
Return Authorization (RA) number must be obtained before shipping your unit to Samson. Without this number, the unit will not be accepted.
Please visit www.samsontech.com/ra for an RA number prior to shipping your unit. We recommend retaining the original packing materials and,
if possible, return the unit in its original carton. If your microphone was purchased outside of the United States, contact your local distributor
for warranty details and service information.
If you have any questions or comments do no hesitate to contact us at support@samsontech.com.
Q7x Professional Vocal Microphone
EN FR DE ES IT
• Dynamic mic element with neodymium magnet provides an
extended range frequency response for optimum reproduction
and exceptionally clear, crisp sound.
• Ultra sensitive element picks up all of the nuances of any
performance
• Frequency response tailored for vocal performance with a mid-
range lift and low-frequency roll off.
• Supercardioid polar pattern minimizes feedback problems and
effectively rejects signals not originating directly in front of the
mic capsule.
• Able to withstands high SPL (Sound Pressure Levels) lending
itself to a wide range of miking situations
• Special pneumatic shock-mounting greatly reduces handling
noise.
• Rugged zinc alloy die-casting case ensures reliable performance
in even the most demanding environments.
• Gold plated XLR Connector
• Includes mic clip.
Features
Unidirectional microphones, exhibit a phenomenon known as
“proximity effect.” Very simply put, proximity effect is a resulting
change in the frequency response of a microphone based on the
position of the microphone capsule relative to the sound source.
Due to the result of the proximity effect, slight adjustments of the
microphone position and angle can make a big difference in sound.
Specifically, when you point the microphone directly at the sound
source (on axis) you will get the best frequency response, however
when you start pointing the microphone slightly away (off axis) you will
notice the low frequency response dropping off and the microphone
will start to sound thinner.
The Q7x will boost bass frequencies when the microphone is between
0 – 2 inches from the sound source. As you move the sound source
further away from the microphone, the bass response will gradually
roll off.

Microphone Placement Guidelines
Listed are some common microphone placement techniques. Use these suggestions as a guide and let your ears determine what works best in
your situation.
• Sound source less than 6 inches away from mic — Full sound, pronounced bass, increased isolation from background noise.
• Sound source 6 inches to 2 feet away from mic — Balanced natural sound, less bass, some background noise.
• Sound source 3 to 6 feet away from mic — Thinner ambient sound.
• Aim the microphone at the desired source. Keep unwanted sound sources at a 135° angle from the front of the microphone.
• Place the microphone as close to the sound source as possible.
• Utilize the 3 to 1 Rule when positioning microphones. A microphone should be placed at least three times the distance from other
microphones as it is from the sound source.
• Never cup your hand over the microphone grill as it can change the performance characteristics of the microphone and may cause
undesired effects to the audio.
Every microphone has a characteristic polar pattern that determines
how well it accepts or rejects signal coming from various areas around
the microphone. For example, omnidirectional mics accept all signals
regardless of wherever those signals originate (in front of the mic,
behind it, to the side, etc.). In contrast, directional cardioid mics are
specifically designed to accept signal coming from directly in front,
and to reject signal coming from behind or from the side. The Q7x has
a supercardioid pattern, which is a variation of the standard cardioid
pattern with a slightly tighter pick-up pattern that helps increase the
side-to-side rejection. For this reason, the Q7x excels in environments
where there is a good deal of unwanted ambient sound (like a live
sound stage) as it deliver signals originating directly in front of the
mic capsule itself while rejecting those that originate from behind.

The Q7x microphone has been designed with a frequency response
that has been tailored for vocal performance with a slight lift in the
mid-range and a low end roll-off. The Q7x also excels at miking
instruments and speaker cabinets. The response is created by the
careful consideration of the microphone element and the design of the
capsule porting.

The Q7x can be connected to any type of equipment that has a
microphone preamp using a standard microphone cable. As shown in
the wiring diagrams below, connect the female XLR end directly to
the Q7x’s gold-plated connector and the other end to the microphone
input.
