Samson Q7x Manual de usuario

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.
