Frequently Asked Questions - HS253 SENNHEISER

How to mount the cap to adjust the highs?

Place the cap on the capsule up to the second notch. Use the short cap MZC2-1 or the long cap MZC2-2 depending on the desired effect.

What wind protection accessories are available?

Two windscreens: MZW 2 (approx. 20 dB reduction) and MZW 02 foam (additional 10 dB reduction). Place the MZW 2 first, then the MZW 02 over it.

What is the humidity resistance of the HS253?

Thanks to the patented tandem diaphragm, the microphone is particularly insensitive to humidity such as perspiration or saliva, ensuring reliability during prolonged use.

Is the microphone compatible with Sennheiser transmitters?

Yes, it is compatible with the SK 50, SK 250 and SK 5012 transmitters via its special 3-pin connector.

What is the polar pattern of the microphone?

The HS253 has an omnidirectional polar pattern, capturing sound from all directions.

How to clean the microphone?

Use a soft dry cloth. Avoid chemicals and excessive moisture. For the foam windscreen, you can wash it in lukewarm soapy water and let it dry.

What is the weight of the microphone?

The microphone with cable weighs approximately 34.4 grams, making it light and comfortable to wear.

Can I use this microphone for live singing?

Yes, it is optimized for live speech and singing transmission, with a response curve adapted for close-miking.

What is the cable length?

The cable is 1.6 meters long, providing sufficient freedom of movement for most uses.

Where to find the response curves?

The response curves are provided on page 38 of the instruction manual, showing the influence of caps and windscreens.

USER MANUAL HS253 SENNHEISER

The HS 2 is a condenser omni-directional headmic fitted with a steel wire cable and a special connector. It fulfils the most stringent demands on sound quality and is extremely rugged. The HS 2 is suitable for both vocal and speech applications in all areas of live work.

HS2 (anthracite):Cat.No.05336
HS 2-1 (bcige): Cat. No. 05337

Features

The frequency response curve has been optimised for close-miking. The treble response can be adapted to different requirements via accessories.
Largely insensitive to penetration of sweat due to the patented tandem diaphragm. This design comprises two individual diaphragms installed on both sides of the diaphragm ring. The bottom diaphragm is electrically active and forms the capacitive electroacoustic transducer together with the back plate. The top diaphragm is passive and seals the microphone against sweat. Robust sealing of the housing is ensured by a silicone ring.

Adapting the treble response to different requirements

Two caps with different lengths are available as accessories. With these caps you can influence the treble response.

Slide the cap onto the microphone head until it locks into place. Please refer to the frequency responses curves on page 38.

Short cap: MZC2-1 Cat. No. 76612
Long cap: MZC2-2 Cat. No. 74645

Attachment of the microphone

Windshields

Wind noise impairs the quality of outdoor recording and close-miking. The MZW 2 and MZW 02 windshields considerably reduce the wind noise.

Please first use the MZW 2 windshield. This windshield reduces the wind noise by approx. 20dB

You may further reduce the wind noise by 10 dB by using the additional MZW 02 foam windshield.

MZW 2 and MZW 02 are available as accessories.
