The 26-II headset series and the HD 26 PRO headphones

The 26-II headset series
and the HD 26 PRO headphones

The HMD 26-II/HME 26-II/HMDC 26-II headsets and the
HD

26 PRO headphones feature dynamic, closed head­phones. The noise-compensating microphone of the
HMD

26-II and HMDC 26-II ensures excellent speech trans­mission even in noisy environments. The headsets have been
designed for broadcast use, e.g. for outdoor broadcast or
broadcast van applications. The HMDC
Gard™ professional active noise compensation. The HME 26-II
is available with an omni-directional or a cardioid micro
phone, making it suitable for either outdoor or studio use.

Features

• Lightweight

• Extremely comfortable to wear, even for extended lis-

tening, due to the patented two-piece automatic head­band and soft ear pads

• ActiveGard™ (switchable) safeguards you from volume

peaks above 105 dB (HME 26-II/HMD 26-II/HD 26 PRO)

• NoiseGard™ professional active noise compensation

reduces ambient noise by up to 18 dB (HMDC 26-II)

• “Flip-away” headphone allows single-sided listening

• Detailed, linear sound reproduction for demanding

applications

Operation

Operation

Turning the microphone boom

The microphone boom can be rotated, allowing the micro­phone to be worn on the left or right-hand side of the head.

Putting on the headset

When putting on the headset, the patented two-piece head­band adjusts automatically.

5

Operation

Positioning the microphone

Bend the flexible microphone boom so that the microphone
is placed at the corner of the mouth. Maintain a distance of
2

cm between microphone and mouth. Always use the sup-

plied wind and pop screen.

Do not position the microphone directly in front of
your mouth as it will pick up your breathing and
plosive noises from your mouth. In addition, moisture
can adversely affect the sound and performance of
your microphone.

When attaching the sound
inlet basket, make sure
that it locks into place
with an audible click.

Make sure not to cover the
sound inlet.

Operation

Adjusting the volume on the audio system

Connect the headset to the corresponding sockets of your
audio system.

왘 Adjust the volume directly on the audio system.

CAUTION

Hearing damage due to high volumes!

This headset is capable of producing high sound
pressure levels. Higher volumes or longer durations
can damage your hearing!

왘 Set the volume to a medium level. Make sure

that you can hear critical environmental sounds.
