Product Overview Congratulations on purchasing the HEDD Type 20 MK2 or HEDD Type 30 MK2. You have acquired very precise monitors with a rich feature set. The main features are exchangable use as a Closed or Ported system, as well as the integration of the on-board HEDD Lineariser®. Please head to the specific section to find out more. As active speakers, the MK2 monitors have an integrated amplifier. You can connect them with a digital interface or analog pre-amplifier.

Box Contents The complete set includes: • one active monitor Type 20 MK2 or Type 30 MK2 • one power cable compatible with the region from where it was sold • quickstart guide • «CoP» leaflet explaining the proper switch from Ported to Closed Mode • «CoP» screw and plugs to seal the bass reflex ports Please make sure your box contents match our listing. How to switch between Closed and Ported MK2 Professional Studio Monitors QUICKSTART © 2021 HEDD Audio GmbH | Heinz Electrodynamic Designs | www.
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 first. 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).
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. Horizontal Setup Placing the speaker horizontally is the best way, as they are designed to be placed like this. Always place them on a solid surface or a stand.
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 find the best position. Listen to some good known records while adjusting, until you get an authentic stereo panorama.
«CoP» Closed or Ported The HEDD Type 20 MK2 and Type 30 MK2 can be used in either closed or in ported mode. These are two fundamentally different systems that are available for the user to compare and choose. There is no definite better between the two systems. We recommend to compare carefully to find 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.

CoP Ported Closed Ported Mode This is the default operating mode. The bass reflex ports are open and allow for a powerful low-end reproduction. This operation mode allows for a higher efficiency and while maintaining access to lower bass regions. CoP Ported Closed Closed Mode In closed mode the HEDD MK2 speaker functions as an infinite baffle speaker. This results in a cleaner sound and increased resolution.
HEDD Lineariser® Due to the physically given relationship between time and frequency, expressed in the groundtaking harmonic analysis or Fourier transform, different tones have slightly different travelling times through loudspeakers. This is true for both active or passive speakers. Broadly speaking, lower frequencies need more time to pass through than midrange frequencies, and these are slower than the high tones. Our HEDD Lineariser® offers a complex phase-correction of your HEDD MK2 monitors.

HEDD Lineariser® By default, the Lineariser rotary switch is turned on. This activates an on-board phasecorrection of our HEDD MK2 monitors. For more information, please refer to the section HEDD Lineariser®. Closed or Ported CoP switches the internal system layout according to the selected option. Please make sure that the plugs are correctly inserted for closed mode. For more information, please refer to the section Closed or Ported.
Low Frequency Range If you choose the extended bass response, the woofer has to deliver much higher amplitudes if very low frequencies occur. As a consequence its maximum sound pressure level (SPLmax) is reduced for low frequencies by 6-10 dB depending on the musical material. The mechanical overload of the woofers is looming much earlier. The default low frequency range may be adjusted according to specific needs. When set to extended, the low frequency response is extended by ~20 %.
Input Selection This 4-position rotary INP. SENS. [dB] DESK FILTERswitch selects which signal to reproduce. “Analog” takes an analog signal from a symmetrical source. ANALOG/AES ANALOG MONO LEFT RIGHT The other 3 positions refer to an incoming digital AES signal. Left, Right or Mono can be extracted from the data. For multi-channel audio that exceeds stereo, for example 5.1 surround sound, the monitors have to be fed through the analog XLR input.
Safety Instructions Please read the following safety instructions carefully before setting up your system. Keep the instructions for subsequent reference. Please read the warnings and follow the instructions. • To reduce the risk of an electric shock, do not open the loudspeaker yourself. Always refer to qualified service personnel. • This is an active loudspeaker. It must be connected with an IEC 60320 AC mains power cord like the one supplied with the product.
Maintenance and Care • Your HEDD audio studio monitor doesn’t need any internal maintenance like lubricating, mechanical adjusting and so on, so there is no reason to open up the speaker cabinet. If servicing will be necessary, refer to qualified service personnel. • For cleaning the surface of the cabinet, we recommend to use a microfiber cloth and simply warm water. Don’t use any aggressive detergent, as it will damage the finish.
Warranty We promise that our products are free of defects in material and workmanship for the duration of twenty-four (24) months from the date of the original purchase.

Trouble Shooting Problem Green Power-LED is “on” but there is no audio output Solution 1. Check the wiring and make sure that all cables are connected correctly. 2. Check if you have selected the correct input via the ANALOG/AES switch on the back panel of the speaker. 3. Check the signal path. Swap the cables of both loudspeakers. You might have one defective signal cable. 4. Connect an audio source directly to the speaker (pay attention to the volume!).
