Remote Mounting The Electronics; System Use - Klein + Hummel 0810 Bedienungsanleitung

However, subwoofer's can be considered to be omni-directional in their typical pass band as the generated
wavelength is long compared to the object producing the sound, therefore it does not matter in which direction
the subwoofer is pointing when placed in the listening environment.

Remote Mounting the Electronics

As the electronics back panel does not seal the enclosure, it can be remote mounted using the REK 2 and SC nn
accessories. If the cabinet is to be flush mounted, care should be taken to ensure that there is adequate
ventilation for the electronics. Although no damage will result, insufficient cooling will cause the amplifier
protection to activate prematurely thereby limiting the system's maximum output level.

System Use

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 correct mains voltage is indicated on the electronics
panel (220-240V or 100-120 V) and that the mains power switch is off. Next connect the input signal cables
(analog or digital as appropriate) and output cables, then power up the loudspeaker. There is a three second
delay before sound can be heard from subwoofer(s) and loudspeakers so as to avoid noises (pops) from
preceding equipment turned on at the same time. During this period the POWER ON light flashes, then it turns
solid indicating that audio can be heard. If there are no lights, check the mains power supply. Conversely, turning
off the subwoofer immediately mutes the audio from the subwoofer and loudspeakers connected to it.
Positioning
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.
