TELEFUNKEN M81-WH2 Wireless Capsule

Product overview

The TELEFUNKEN M81-WH2 Wireless Capsule is a M81 dynamic capsule head in a black nickel finish for compatible handheld wireless transmitters in the TELEFUNKEN -WH2 compatibility group.

The M81-WH2 brings the M81's condenser-like performance, midrange clarity and high SPL handling to the wireless stage. It uses the same low-mass diaphragm and custom-wound output transformer as the handheld M81 Standard and the low-profile M81-SH, so it delivers the sound quality and reliability expected from a TELEFUNKEN Dynamic Series microphone. TELEFUNKEN designed it to minimise handling noise and to mate seamlessly with the wireless system of your choice: fit it to a compatible handheld transmitter and the singer keeps the M81 sound without a cable.

The M81 character on a wireless transmitter

TELEFUNKEN designs its wireless capsule heads to deliver the same sonic character and high SPL handling as the handheld versions. For the M81 that means its smooth frequency response and exceptional midrange articulation. The M81 has a more neutral, flatter response with increased midrange clarity; its clarity and wealth of body make it an ideal tool for taming brighter vocals, and it is built around a low-mass diaphragm designed to reduce proximity effect. TELEFUNKEN recommends the M81 for female vocals, toms, distorted guitar amps and brass.

Built for the stage

The Dynamic Series is a modern staple of live sound reinforcement and studio recording. Its sonic performance is mated with intelligent internal construction for low handling noise and dependable durability, and the M81-WH2 carries that design into a capsule head. The supercardioid pattern gives the condenser-like response, minimal proximity effect and superior feedback rejection TELEFUNKEN Dynamic Series microphones are known for, which helps keep vocals clear in front of monitor wedges. As a dynamic capsule head it needs no phantom power.

Made for singers who move

Handheld wireless singers move, grip the microphone and change distance all the time. The M81-WH2 is intelligently designed to minimise handling noise, and the minimal proximity effect of the Dynamic Series keeps the low end consistent as the singer moves closer to or further from the capsule. With high SPL handling of 135 dB SPL for 1% THD, it copes with powerful voices at close range.

Choosing the right fitting

TELEFUNKEN makes its M80 and M81 wireless capsule heads in two fittings, -WH and -WH2, and publishes a compatibility list that names the professional handheld wireless transmitters each fitting suits. The two fittings are listed for different transmitter families, so the M81-WH2 is the right choice when your handheld transmitter appears in the -WH2 group of the TELEFUNKEN compatibility list. If your transmitter is listed in the -WH group, choose the M81-WH instead. Shivansh Electronics can help you check your transmitter model before you order.

One sound across the system

Each Dynamic Series model has its own strengths and complements the others, giving a cohesive sound in multi-microphone applications such as vocal groups, horn sections and drum sets. Because the M81-WH2 keeps the character of the handheld M81, a wireless lead singer and wired M81 or M80/M81 microphones on backing vocals sit together naturally in the mix.

Stage tips

• Hold position: keep the capsule close to the mouth and pointed at the singer, and avoid cupping the head
• Monitor placement: keep wedges out of the direction the capsule faces so the supercardioid pattern can reject them
• Gain: set transmitter and receiver levels at full performance level during the sound check
• Spares: keep a spare -WH2 head and fresh batteries at the side of the stage
• Check the list: confirm every transmitter in the system against the -WH2 group of the TELEFUNKEN compatibility list

Fitting and care

Switch the transmitter off and mute its channel. Remove the fitted capsule head from the handheld transmitter, then fit the M81-WH2 as described in the transmitter maker's instructions until it is fully seated. Switch the transmitter on, check the battery and RF signal, and set gain at full performance level. Keep spare capsule heads in a clean, dry bag and store the transmitter with the head fitted to protect the contacts.
