Frequently Asked Questions - LM7x SAMSON

How to attach the LM7x microphone?

Attach the microphone to the shirt or jacket using the provided clip, about 20 to 25 cm from the chin, with the capsule aimed toward the mouth. Make a small loop with the cable to reduce cable noise.

What adapters are included with the LM7x?

The LM7x comes with four cables and adapters: a 3.5 mm connector (for Sennheiser), a Hirose 4-pin connector (for Audio-Technica), a Switchcraft TA3F connector (for AirLine and AKG), and a Switchcraft TA4F connector (for Shure).

What is the polar pattern of the LM7x?

The LM7x has a unidirectional (cardioid) polar pattern. It primarily picks up sound from the front, improving separation and reducing ambient noise.

How to reduce wind or breath noise?

Use one of the included windscreens: a fuzzy windscreen for maximum reduction, or the standard windscreens. Place it over the microphone capsule.

Can the LM7x be used with other wireless systems?

Yes, thanks to the four included adapters, it is compatible with most portable wireless transmitters from Sennheiser, Audio-Technica, AKG, and Shure.

How to choose the right adapter for my system?

Refer to the table in the manual: the 3.5 mm connector fits Sennheiser systems, the Hirose 4-pin fits Audio-Technica, the TA3F fits AirLine/AKG, and the TA4F fits Shure. Align the cable with the threaded terminal and screw gently without forcing.

What is the sensitivity of the LM7x?

The sensitivity is -37 dB 1V/Pa ±3 dB at 1 kHz, which is a standard value for lavalier microphones.

How to clean the LM7x microphone?

Clean the microphone with a soft, dry cloth. Avoid water, solvents, and abrasive cleaners. Protect it from excessive moisture.

What is the operating voltage of the LM7x?

The LM7x operates with a voltage of 1.5 to 12 V DC, making it compatible with most wireless transmitters.

Introduction

Thank you for purchasing the Samson LMx lavalier microphone! Delivering outstanding audio quality, the LMx lavalier microphones are perfect for presentations, broadcast, theater and worship application.

The LM7x is a features a 6.84mm capsule in a marine-grade stainless steel housing. It has a unidirectional pick up pattern, which captures more sound in front of the microphone, creating better separation and isolation which translates to more gain before feedback and less pickup of ambient room sounds.

The LM10x is a low profile microphone with a 3mm capsule with omnidirectional pick up pattern. The microphone's off axis frequency response is linear, resulting in a clear and articulate reproduction regardless of the position of the capsule relative to the sound source.

The LMx lavalier microphones are particularly well-suited for use with Samson wireless systems and with four included adapters, the microphones can be used with most any other manufacturer's wireless body pack systems. The kit also includes four windscreens and carry case.

Manufactured with extreme care and the highest quality components, LMx lavalier microphones deliver exceptionally clear, articulate sound with reliable performance. If you have any questions or comments regarding the LMx Lavalier Microphone or any other products from Samson, do no hesitate to contact us at [e-mail].

Positioning the LM10x

• Attach the microphone to the performer's shirt or jacket, using the included microphone clip, approximately 8"–10" below their chin with the microphone facing towards their mouth.
• Using a small loop in the microphone cable will help reduce cable noise when the performer moves.
• Use one of the included windscreens to reduce breath or wind noise, when using outdoors.
• To further conceal the microphone, it can be placed behind clothing, but this will affect the high frequency performance of the microphone, behind a button, in the performers hairline or even taped to a pair of glasses.
• With the performer talking into the microphone, listen to the quality of the audio, and adjust the positioning of the microphone until a balanced sound is reached.
