HSC 271HSC 171

These professional headsets from AKG have been designed for broad­cast and recording use. Derived from the high quality, extremely
accurate K 171 Studio and K 271 Studio headphones, the headsets
are available with either a condenser or a dynamic microphone.

In addition to excellent comfort, optimum ambient-noise attenuati­on, and outstanding audio quality, the HSC and HSD Series profes­sional headsets use the same proven detachable cable as the Studio
Series headphones. So should a cable become defective under the
enormous stress of day-to-day broadcast work, it can be replaced
quickly and without any tools.

The flexible microphone arm swivels through a 270-degree arc and
mutes the microphone automatically as you move it up – no need to
fumble for a mute button! Also, you can wear the microphone to the
left or right of your mouth depending on your preferences or availa­ble space.

Commentators, off-camera moderators, camera operators, or sound
engineers – AKG professional headsets are always the perfect tools
for any application in professional audio and satisfy every user’s per­sonal preferences.

Swiveling through 270 degrees, the
microphone arm allows you to place
the microphone on the left or right of
your mouth. Noiseless microswitches
automatically activate and mute the
microphone.

The detachable cable is easy to ser­vice or replace if defective. A rugged,
locking 6-pin mini XLR connector car­ries all signals to and from the head­set.

All HSD models provide the micropho­ne signal on a standard 3-pin XLR
connector, HSC models on a 3-pin
XLR with an integrated phantom
power adapter and switchable bass
cut filter.

The HSD 271 is also available in a spe­cial version with a single earphone.
This model is the perfect choice for all
jobs where the user needs to listen to
natural sounds as well as those coming
through he headphones.
