As the original packing is primarily designed to get the loudspeaker from the
factory to the end user, it is highly recommended that a flight case is used if the
loudspeaker is regularly moved between locations.

Klein + Hummel loudspeakers should only be used indoors and in these ambient
conditions:
•
+10° C to +40° C (+50° F to +104° F), <90% relative humidity, non-condensing
During transport or storage the ambient conditions can be:
•
-25° C to +70° C (-13° F to 158° F), <90% relative humidity, non-condensing
Before connecting the mains power cable, ensure that the rear mains power and front
panel switches are set to off and that the correct mains voltage (85 … 240 V) or external
voltage (12 … 20 V) is available. Next connect the input signal cable (analogue, digital, or
both as appropriate) and power up the loudspeaker. The front panel light should be
glowing red or green depending on the position of the volume control. If the light is off,
check the mains or external power supply. In the M 52 D, select the required signal on the
front panel switch. Next raise the volume control until the desired audio level is achieved.
In a studio application, the loudspeakers should be placed according to the ITU-R BS.775-1
recommendations so there is consistency of reproduction when compared to other
listening environments. For movie applications, ANSI/SMPTE 202M is the preferred
standard for system setup. For home use, as materials are mixed in ITU style rooms, one
should get as close as possible to this configuration to maximize replay authenticity.
For two-channel stereo, ±30° should be used. There are currently no internationally
agreed standards for 6.1 or 7.1 formats. However common practice is to use one or two
loudspeakers in the centre back location of a 6.1 system. In a 7.1 system common practice
is to place side loudspeakers at ±90° and to push the surround loudspeakers back to
±150°.
