Dear Customer,
many thanks for choosing the HEDD Type 30 active mid-
fi eld studio monitor. You got yourself a powerful, dynamic
and ultra-transparent 3-way system, especially suitable for
• in-depth stereo- and multichannel-mixing
• high-end recording
• broadcast applications and
• mastering
Whether as a full range audio monitor in an elegant
studio space or in a broadcast context, the Type 30 is an
ideal player in the most diverse fi elds of application. The
impressive technological facts alone speak for themselves:
Two horizontally aligned 7”-woofers, a dedicated 4”-mid-
range woofer made of very stiff Honeycomb-sandwich
material, Klaus Heinz’ latest version of the handmade
Air Motion Transformer tweeter, and nothing less than
4×300W of ICEpower® amplifi cation create an ultra-
wide frequency range from 32Hz all the way up to 50kHz.
In addition to being super solid and having an extremely
high fi delity in the bass and mid range reproduction, the
HEDD AMT produces vivid and uncolored high frequency
material.
On the following pages, we would like to share with you
some tips and advice regarding the operation of this fi ne
product.
Thanks again, and enjoy your new speakers!
Klaus Heinz and the HEDD Team
UNpACKINg AND CONNECTINg
• Unpack the monitor carefully and give it an hour to ac-
climate to the temperature of your room
• Connect it to the power-socket
• Connect your audio source via the balanced XLR
(6),
unbalanced RCA
(5), or HEDD Bridge inputs (8), then
select the chosen input with the INPUT SOURCE
SWITCH on the back panel
(4).
Every HEDD studio monitor is equipped with regulated
Universal Mains, working from 85V-264V. This means that
the amps will work at their full capacity under any voltage
condition. Plug and play – whereever you are.
gAIN (3)
The Gain control lets you adjust the overall volume of the
speaker in a range from -30dB to +6dB. You can use this
control to make the speaker work fl awlessly with your
other equipment or to compensate for any level diff er-
ences between the speakers, may they be caused by your
listening position, the room acoustics, or slight variations
of the control knob’s tolerance.
SHELVINg FILTErS (1 & 2)
Listening to these monitors can be a real joy, but depend-
ing on the acoustical properties of the room you are
working in, it might at times be diffi cult for the speakers
to unfold their rich sound quality. It is precisely for this
reason that we included two highly effi cient shelving-
fi lters (Low Shelf < 200Hz / High Shelf > 2kHz) that are
designed to overcome defi cient acoustics, typically found
in rooms with uneven geometries, hard (glass, stone) or
overly muffl ed (carpets, curtains) surfaces.
