For
MAHLER
Please take care of an important feature of Mahler: On the backside of Mahler, on the
terminal, under the binding posts you will find 2 sinkings, housing 2 tiny switches being
moved by any sharp tool. Small switch, big effect: This is an important Room Tuning aid:
One allows room-tuning by lifting bass for bass-swallowing rooms:
Symbols: B is for Bass, N is for Neutral, + is for stronger bass.
One switch is lowering lower treble for e.g. echoing undamped walls:
Symbols: H is for High frequencies, N is for Neutral, - is for smoothened tweeter
response.
In neutral position N both switches do not have any contact to the circuitry!
You can influence Mahler's environment not only with the switches, but by positioning
Mahler regarding his basses on the side. As they are mounted on one side of the cabinet
(left and right speaker), it is possible to let them fire inwards or outwards and so to
influence the bass response to match room acoustic. This room-tuning is made possible
by the bass-modes in a room, which change immediately by being stimulated on
different places. As an indication, in most cases a positioning with basses outwards
creates a more powerful bass response, whereas basses inwards tend to more slender
bass reaction. We suggest to start with position "outwards".
When mounting the base to the Mahler bottom please note that the base is mounted in
the right direction, so that the frontplate juts out:
