LH 28 Mounting manual

Tripod Stand Adaptor

Important safety and mounting instructions

• Have the product mounted by a specialist.

• Due to his/her technical training, know-how and experience as well

as knowledge of relevant provisions, regulations and standards, the

specialist must be able to assess assigned tasks, recognize poten-

tial hazards and ensure appropriate safety measures. The following

safety and mounting instructions are addressed to this specialist.

•

Read and follow the safety and mounting instructions, keep these

instructions and always include them when passing the LH 28 on

to third parties.

•

Also read and follow the installation instructions contained in the

operating manual of the mounted loudspeaker.

• When mounting, observe and follow the local, national and interna-

tional regulations and standards.

•

Mount the LH 28 in combination with other accessories from the

Neumann mounting hardware range to loudspeakers with a maxi-

mum weight of 65 kg (143.3 lbs).

•

The LH28 is suitable for suspended mounting. The locking not

screw B protects the LH 28 from rotating, but does not provide

su cient protection against tensile stress. Only use the LH28 for

mounting on loudspeaker stands or subwoofers as shown in ﬁ g. 4.

•

Do not install the LH 28 in locations where it is exposed to externally

generated vibrations.

• Always use the original supplied parts.

In the following you will be asked to combine other acces-

sories from the Neumann mounting hardware range with the

LH28. Download the PDF ﬁ le “Hardware Mounting Matrix”

from www.neumann.com. Only combine the Neumann moun-

ting hardware as speciﬁ ed in the “Hardware Mounting Matrix”.

•

Fasten your loudspeaker to a Neumann mounting hardware that is

also suitable for mounting to the LH28 (e.g. LH 25, LH36, LH61,

refer to the ). Follow the safety and “Hardware Mounting Matrix”

mounting instructions contained in the operating manual of the

selected mounting hardware.

• Attach the LH 28 to the mounting hardware/loudspeaker combina-

tion (see ﬁ g. 1).

–

If di erent mounting positions are possible, choose mounting

points that minimize leverage when the loudspeaker is tilted.

– Tighten the nuts with a torque of 20Nm.

•

Loosen the locking screw on the LH28 so that the LH28 can be B

fully slid onto a tripod stand.

CAUTION!

Danger of injury and material damage

due to dropping of the loudspeaker

Unless the LH 28 is properly fastened, the loudspeaker together

with the mounting hardware can drop down.



Have the loudspeaker held by a second specialist who is

physically able to do so. The requirements mentioned earlier

also apply to this specialist.



When mounting the loudspeaker, provide a su cient addi-

tional protection against dropping.

•

Slide the LH28 with the mounted loudspeaker as far as it will go

onto a tripod stand with a tube diameter of 35mm (1 . ⅜”)

You can also use the LH28 for mounting a loudspeaker onto

a Neumann subwoofer (see ﬁ g. 4). For this, you require a

distance rod (to be ordered separately) with the following

characteristics:

• diameter: 35mm (1⅜”);

• as short as possible to minimize leverage;

• manufacturer-rated for the weight that is to be supported.



First slide the distance rod into the subwoofer‘s mounting

ﬂ ange, then slide the LH28 onto the distance rod.

• Tighten the locking screw .B

•

Use safety wires to additionally protect the loudspeaker and the

mounting hardware against tipping/dropping. The safety wires, rope

terminations and coupling links must comply in their dimensioning

and condition with the regulations and standards of the country in

which they are used and must reliably prevent tipping/dropping of

a load of 65 kg (143.3 lbs; when mounting the loudspeaker onto

a subwoofer, you have to add the weight of the loudspeaker and the

mounting hardware).

• Make sure that ...

–

you use both screws D to fasten the LH 28 to suitable Neumann

mounting hardware;

–

the LH 28, the associated mounting hardware, the loudspeaker

and the tripod stand cannot tip over or drop down, even if the

power or audio cables are pulled;

–

you replace the safety wires and coupling links by new ones when

they have prevented tipping/dropping;

–

you check every 3 months if all screws are properly tightened

and if the LH28 and associated mounting hardware, additional

fastening elements, safety wires and coupling links, as well as the

loudspeaker are in proper condition.

In case of any damage or any deviation from the safety and mounting

instructions, immediately dismount the loudspeaker, the LH28 and the

additional mounting hardware used.
