Frequently Asked Questions - MXGN-12C Senal

Does the MXGN-12C require phantom power to operate?

Yes, the microphone requires phantom power DC 12 to 48 V. Ensure phantom power is enabled on your mixer or conferencing system.

How do I change the microphone capsule?

Unscrew the existing capsule from the gooseneck, then screw on the new capsule. Do not overtighten. Compatible capsules: cardioid (included), omnidirectional (MXGN-ICO), and supercardioid (MXGN-ICS).

What are the different mute modes and how do they work?

There are three modes: Mute (mic always on, touch and hold to mute), Talk (mic always muted, touch and hold to talk), and Lock (tap to toggle on/off). Select via the talk/mute switch.

How do I activate the low-cut filter?

Move the selector switch to the Low Cut position to reduce low-frequency noise (e.g., air conditioning, fans). Moving it to Flat turns the filter off.

What is the recommended microphone placement for best sound?

Place the microphone 6 to 12 inches from the sound source and point it directly at the speaker. Keep it away from speakers and other noise sources.

How should I clean and maintain the microphone?

Use only a soft, dry cloth to clean the exterior. Keep it away from water and flammable substances. Do not disassemble.

What does the LED ring light indicate?

When the LED ring is on, the microphone is active. When it is off, the microphone is muted.

Is the MXGN-12C compatible with standard XLR inputs?

Yes, it has a 3-pin male XLR output connector. Use a standard XLR cable to connect to mixers, conferencing systems, or audio interfaces.

What is the warranty period for this microphone?

The product comes with a 2-year limited warranty covering defects in materials and workmanship. Contact Senal Customer Service for returns.

Can I use the MXGN-12C for live sound amplification?

Yes, it is suitable for live sound reinforcement when connected to a mixing console with phantom power. The cardioid pattern reduces feedback and background noise.

MXGN SERIES

PROFESSIONAL CARDIOID GOOSENECK MICROPHONE WITH INTEGRATED BASE

Thank you for choosing Senal.

Senal's MXGN-series Professional Gooseneck Microphones are sleek microphones that are designed with optimized frequency response and sensitivity ideal for capturing voices. The included cardioid microphone capsule is perfect for video conferences, lectures, and meetings. To adapt your microphone for other conference, speaking, or desktop applications, the MXGN-series is designed for interchangeable omnidirectional and supercardioid capsules (available separately).

The MXGN-series microphones integrate into most AV conferencing systems or sound systems. For quiet and professional audio, balanced output rejects unwanted RF and EM interference and noise, even over long cable runs, and a low-cut filter minimizes room noise and low-end rumble. A programmable touch pad mutes or activates the microphone with a gentle finger tap, and an LED ring light located on the gooseneck is a visual indicator of the mic's status. For public speaking applications, the microphones' stylish and slim appearance won't obscure or distract attention away from the person behind the microphone.

Setting Up the MXGN Gooseneck Microphone

Each application of the MXGN Microphone will be slightly different. The following scenarios cover frequently used setups.

Live Lecture/Sound Reinforcement

This is ideal in an auditorium or house of worship where a voice needs to be amplified for an audience.

Note: MXGN microphones need phantom power in order to operate.

Video and Audio Conferencing

MXGN microphones are compatible with most audio and video conferencing systems. Refer to the conferencing system's user manual for setup instructions.

Powering the MXGN Microphone

The MXGN microphones operate on phantom power. Once connected to the power source, the MXGN mic is ready to work.

Important! When integrating the MXGN microphone into a video or audio conferencing system, or using it with a mixing board, make sure that phantom power is enabled.

Optional Mic Capsules

The MXGN-12 and MXGN-18 include a cardioid mic capsule. Omnidirectional (MXGN-ICO) and supercardioid (MXGN-ICS) capsules are available separately.

To exchange capsules, unscrew the capsule that's attached to the gooseneck, and screw on the replacement capsule. Be sure not to overtighten the capsule when installing it.

Cardioid Polar Pattern

The cardioid capsule lessens off-axis noise. Use it in rooms with inadequate acoustic treatment or in spaces where background noise is problematic. The MXGN will capture the voice of the person sitting directly in front it while it minimizes room noise and reverberation.

Omnidirectional Polar Pattern

The omnidirectional capsule picks up sound in a 360-degree pattern. Use it in quiet rooms with adequate acoustic treatment. The microphone will pick up all participants seated on the same side of a table. Alternatively, it can be used to capture several people seated around the microphone.

Supercardioid Polar Pattern

The supercardioid capsule has a slightly narrower pickup field and rejects more off-axis noise than the cardioid capsule. This capsule is an excellent choice for a stationary lecturer at a podium or for speaking in high-noise environments. It can be used in a multi-microphone setup, providing that it's pointed directly at the person using it.

Using the MXGN Gooseneck Microphone

Using the Windscreen

The MXGN microphone should always be used with the included foam windscreen. It prevents the vocal pops that occur with the letters P and B, and it protects the mic capsule from corrosive moisture.

To install the windscreen, slip it over the microphone capsule.

Microphone Placement

The optimum placement for the microphone is 6 to 12 inches from the source.

Ideally, the microphone should be pointed directly toward the source for capturing the best sound.

Always point the microphones away from speakers and other sources of unwanted noise.

Powering the MXGN Microphone

The MXGN microphones operate on phantom power. Once connected to the power source, the MXGN mic is ready to work.

Important! When integrating the MXGN microphone into a video or audio conferencing system, or using it with a mixing board, make sure that phantom power is enabled.

Low-Cut Filter

Activate the low-cut filter when using the microphone in rooms with inadequate acoustic treatment or constant noise from air conditioning, fans, or lights.

To filter out low frequencies, move the selector switch to the Low Cut position. Moving the selector to the Flat position turns off the low-cut filter.

Talk/Mute

Move the switch to select the talk/mute function of the touch pad.

When the LED ring light is on, the microphone is on.

When is the LED ring light is off, the microphone is muted.

The touch pad on the microphone's base controls the programmable mute function. There are three programming options.

Mute

In Mute mode, the microphone is always active. Touch and hold the sensor pad to mute the microphone, and release to activate the microphone again.

This function is useful for momentarily muting the microphone if you need to cough, or to say something that isn't heard by other participants.

Talk

In Talk mode, the microphone is always muted. Touch and hold the sensor pad to activate the microphone, and release to mute the microphone again.

This function is useful for a participant that needs to speak only occasionally. Keeping the microphone defaulted to mute prevents too many open microphones at one time, and minimizes the chance of feedback, excessive noise, or interference.

Lock

Tap the sensor pad to change the microphone's status. The microphone will stay on or muted until you touch the sensor pad again.

Selecting Lock is ideal for meetings where conversation between participants is expected. Alternatively, each participant can activate the microphone to speak individually, and then mute the microphone to listen to the other remarks.

Troubleshooting

Problem Solution

The microphone is connected, but there's no sound.
