Low Frequency Range

The default low frequency range may be adjusted according to specic needs. When set

to extended, the low frequency response is extended by ~20 %. In the case of Type 05

MK2 the -3dB point goes from 45 Hz down to 36 Hz, for Type 07 MK 2 it changes from

38 Hz to 30 Hz.

In case the monitors are used in a Satellite-Subwoofer system together with our BASS

series, the switch has to be set to “for SUB”.

In case the monitors are used in a Satellite-Sub-system together with our BASS series,

please use the analog output to the satellites of the BASS 08 or 12 unit to get a

completely linear phase Satellite-Sub-system. In case you feed the full range signal to

both the satellites in parallel to any subwoofer (HEDD or other) set the switch to “for

SUB”.

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.

If a BASS 08 or bigger HEDD subwoofer is used, it is preferrable to use

the analogue outputs from the sub. The HEDD BASS subwoofers have a

Lineariser® on board as well, therefore the overall bass signal is delayed

by approximately 30 ms. They are added to the analog output so that an

all in all linear phase Satellite-Sub-system is in place. In this very case you

may set the switch to “for SUB”.

Should the listening distance vary between subwoofer and MK2 monitor

with respect to the listening position, you may compensate on that with

the “Sat. oset” rotary switch by 2m in .5m steps.
