ARCHITECT’S
SPECIFICATIONS
Broadcast headphones have to be provided
with a high Maximum Sound Pressure Level and
a very accurate sound reproduction. The swivel-
ling ear cap allows listening to the environment
whenever needed. The headphones are light
weighted, provide expandable split headband
and extra soft ear cushions and headband
paddings for outstanding wearing comfort even
during long production days. The ActiveGard™
limiter technology protects hearing from volu-
me peaks above 105 dB. Following the modular
concept, ear cushions and paddings can be
replaced easily. Corresponding cable-II family
is copper material reinforced with Kevlar® for
highest durability. The special shape with short
coiled part absorbs structure born noise coming
from cable perfectly.
The HD 26 PRO applies to the requirements of demanding broadcast
productions. A very linear and true sound reproduction will make these
headphones an essential tool for professional monitoring applications.
The closed, supra-aural headphones
have a very good passive noise
attenuation, a high maximum SPL
and are equipped with the ActiveGard™.
This limiter can be activated or
deactivated. Headphones come with
cable with 3,5 mm jack plug and screw-on
adapter for 6,3 mm (¼“) jack plug.
