How to switch between Closed and Ported
-6-
Getting Started
Make sure the main power switch is in the "0" position, then connect the power cord to the
power socket.
Set the power switch to "1". Please note that the LED becomes green immediately but it
may take up to 15 sec to power up and play music. Warning: High volume may damage your
hearing! Consider lowering the volume rst.
Connect your audio source via the balanced XLR socket, then select the desired input with
the ANALOG / AES rotary switch on the back plate (bottom left). For digital AES input,
please choose the signal (left, right, mono).
As there are quite a number of control knobs on the backplate we recommend to start
playing music with all the markers in the "Up" position:
ALL "0" and "↑" POSITION = FACTORY SETTING
Status LED
The front LED panel of the speaker will indicate its operational status as follows:
The monitors automatically jump into stand-by after 30 minutes. They wake back up when
audio is played.

Speaker Setup
To achieve the best possible sound and unfold the full potential of the HEDD MK2
monitors, the correct speaker placement is very important. Please follow our guide below.
Vertical Setup
Placing the speaker vertically is the best way, as they are designed to be placed like this.
Always place them on a solid surface or a stand.
Horizontal Setup
If you like to place the speaker horizontally in a stereo or surround setup, make sure that
they are aligned symmetrically: The Tweeters both should face either outwards or inwards.
Otherwise, the acoustical image will not be correct.
Height Positioning
Place the speaker in a position so that the tweeter matches the height of your ears when
you are on your listening position. If this is not possible, tilt the speaker so that the tweeter
aims at your ears. Try to avoid that the tweeter is placed too low or too high, as this may
result in a mued or less dened sound.
-8-
Stereo Positioning
For optimizing the stereo listening position, place the two speakers so that they form an
equilateral triangle with your listening position. Your listening position should be on an
imaginary center point between the two speakers. Adjust the distance of the speakers and
the distance of our listening position accordingly to nd the best position. Listen to some
good known records while adjusting, until you get an authentic stereo panorama.
Surround Positioning
For a surround listening setup, place the speakers in a circle around your listening position
in following angles: Center 0°, Front Right 30°, Rear Right 110°, Rear Left 250° and Front
Left 330°. Radius of the circle should be between 0.7m - 2m. Surrounding walls should be
at least 40cm away from every speaker to avoid early reections. It is preferrable to use
the same type of speaker for every channel (except the subwoofer, of course), because
otherwise negative frequency and/or phase coloration can occur. Refer to the ITU
recommendation BS.2159-4 for a detailed explanation.

Stand/Wall Mounting (Type 05 MK2 only)
The Type 05 MK2 speaker is equipped with two M6 (6mm) strew threads on the rear side
for stand/wall mounting. Spacing between the two screws is 60mm. Please contact us for
more information on suitable mounting hardware.
Please refer to the Product Overview for the location of the M6 strew threads.

«CoP» Closed or Ported
The HEDD Type 05 MK2 and Type 07 MK2 can be used in either closed or in ported
mode. These are two fundamentally dierent systems that are available for the user to
compare and choose. There is no denite better between the two systems. We
recommend to compare carefully to nd the optimal option for your environment and
listening habits.
Switching Between Closed and Ported
By default, the HEDD speakers are "ported." This means that the bass port is open. To
switch to "closed" mode, please follow the steps below.
1. Insert the included HEDD plugs with help of the HEDD screw to close the ports.
Make sure that the screw is facing outwards!
Push the plugs deep into the bass ports. Make sure that
you can still reach the screw comfortable with your
ngers to pull it out. The plug should not go deeper than
when the bass port starts to bend and the resistance
increases. Once inserted, feel free to unwind and
remove the screw.
2. Switch the knob on the backpanel of your monitors to Closed mode.
Please note that the headroom in Closed Mode is limited compared to Ported Mode.
We highly recommend to lower the volume before switching.
from Closed to Ported
To switch back to Ported Mode, stop the audio
playback, wind the screw back into the plug, gently
pull the plug back out again and change the rotary
switch on the backpanel to Ported.
