HEDD TYPE 30 Operation Manual Download Page 4

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.
