General Assembly hints#

Preliminary remarks#

Unpack all packets and boxes before starting with the assembly to get an overview.
Pay special attention to the details of the aluminum profiles in packet 2. The profiles are identified in this manual by length and features like hole-count. Some profiles have identical lengths and may appear identical on first sight, but still differ in small details.
Leave all parts in their bags as long as you don’t need them! This will make it easier to find the parts you need at the specific step.
The numbering of the bags is primarily based on the assembly order.
The open face ends of all aluminum profiles may have sharp edges. Be careful during the assembly procedure to avoid injuries before all open face ends are covered by plastic caps!
Use only the provided manual tools unless specified otherwise. Do not overtighten screws!

How T-nuts are used#

T-nuts are an important connecting tool for the aluminum strut profiles of the Near Field Scanner.

They are very handy compared to normal slot nuts because it is not necessary to insert them into the end of the slot. Instead, they can be inserted at any place along the slot. By tightening the screw, the T-nut turns and locks inside the slot as shown in the picture below. The example on the right side shows what happens if the T-nut is not inserted correctly into the slot. In this case the T-nut is not able to turn within the slot.

Some joint locations are predefined by drilled holes in the profiles to simplify exact positioning of the joint. At these locations, longer screws are used, that reach through the T-nut into the hole.

How screws are distinguished#

Apart from the microphone periphery only metric hex socket screws are used.

You will find screws with four different kind of heads in various sizes:

Cylinder head#

DIN 912 / ISO 4762 (In this manual just referenced as screw)

Low-profile cylinder head#

DIN 6912

Countersunk head#

DIN 7991 / ISO 10642

Half round head with collar#

ISO 7380-2

Notation example

M6x40 means:

thread diameter d = 6mm
length l = 40 mm.

Note

Note that the length of countersunk head screws is measured over the whole screw including the head!

Use of Assembly Paste#

Due to occurring seizing between screws and components we recommend to use the assembly paste provided. This will facilitate the partial disassembly of the NFS at a later date, e.g. for moving it to another location. Apply assembly paste on every countersunk head screw before inserting it.

Squeeze a small heap of paste onto one side of the lowest turns of the screw as shown in the picture. Screw it in as usual.

You have used the right amount if a little paste is pressed out from under the screw’s head when tightening. Remove the excess with a dry cloth.

How cable plugs are distinguished#

Note

Packing Structure#

Parts Lists and Assembly Steps#

This manual is structured in chapters which chronologically describe the assembly steps of each major subcomponent of the NFS.

Each assembly chapter is led by a parts list which lists the parts used in the assembly of the chapter and the respective location of this part in the packing-structure. Each part in this assembly list is identified by an alphanumerical designator by which it is referenced in the following assembly steps. The designators reset for each assembly chapter and are only unique in the respective chapter.

Required torque settings#

Some screws and fasteners of the NFS require the application of a specific torque during the assembly. Those assembly steps arm marked with the symbol Nm and a torque indication.

Example:

All assembly steps without a specific torque indication are less critical. Refer to following table as a guideline on how much torque should be applied during the assembly, indicated by the size of the screw or fastener:

Recommended Torque and Tool for Screws#

M3: Torque: 1 Nm

Tool: Screwdriver handle
M4: Torque: 2 Nm

Tool: Screwdriver handle
M5: Torque: 4 Nm

Tool: Screwdriver handle
M6: Torque: 8 Nm

Tool: Torque wrench
M8: Torque: 16 Nm

Tool: Torque wrench
M10: Torque: 20 Nm

Tool: Torque wrench

Screw Size	Recommended Torque	Recommended Tool

Mounting instruction#

Step 1, 2: Brace Stump And Floor Profile#

Mount a brace stump (C) with an M8x25 screw from the same bag to the floor profile (B).

The threaded rod of the brace stump has to face away from the chamfered edge of the floor profile as shown in the picture.
Repeat for all 4 floor profiles.

Step 3: Arrange Table#

Arrange the table A upright, loosen and remove the four M8x40 screws at the bottom (one at each side) as shown in the picture.

Step 4, 5:#

Loosen the screws (circle in picture) on every side of the table so you can rotate the cross braces outwards.
Mount the 4^th cross brace which is packed individually in the same manner.

Step 6:#

Plug the threaded rods of the brace stumps into the core drilling of the corresponding cross brace.

Step 7:#

Attach the floor profile to the base of the table using the M8x40 screws from Step 3: Arrange Table.

Step 8, 9:#

Loosen the screws on the left profile connector inside each cross brace and slide the connector down into to the brace stump as shown in the picture.
Attach the profile connector to the brace stump by tightening the lower two screws of the connector.

Note

Do not retighten the upper two screws of the connector at this point
Leave the right profile connector in the cross brace in its original position at this point.

Step 10:#

Insert swivel-in sliding blocks (E) into each of the 4 cross braces to mount the small brackets with M8x12 screws (F).

Step 11:#

Fasten the upper mounting of the cross braces. Repeat this for all 4 brackets/profiles.

Step 12, 13:#

Remove premounted bolt (H) from the small profile (G).
Insert profile G into table at the indicated location and attach it with bolt (H) from the bottom side of the table.

Step 14 - 19:#

Unfold the drill guide and place it flat on the floor at the chosen NFS position.
Drill holes into the floor with a diameter of 12mm and a minimum depth of 80mm.
Clear the drilled holes of any debris with the blow-out pump.
Place the NFS table assembly on the drilled holes.
Insert all 8 ground anchors (I) through the holes of the floor profiles into the drilled holes with a hammer.
Tighten all 8 ground anchors (I) as tight as possible with the small 13mm wrench.

Stand assembly#

List of parts#

Bag 36#

ID	Pcs.	Description
A	1	Loudspeaker cable 4p (3m)
B	1	Loudspeaker extension cable 4p (10m)
C	1	Loudspeaker extension adapter

Bag 9#

ID	Pcs.	Description
D	1	Rotary disk filler
E	2	M5x16 countersunk screw

Packet 2#

ID	Pcs.	Description
F	1	Main Tube 50x1260

The heavy main tube (F) will be the stand of loudspeakers during measurements with the NFS. All loudspeaker cables need to pass through this tube. If you want to use some other kind of cable (like RCA or XLR for active speaker) it is convenient to also mount these cables at this step!

Mounting instructions#

Step 20:#

Measure the distance between the top of the locking assembly and the top of the pivot bearing as shown in the picture. Is this distance more than 28mm?

Yes: continue with step 21: insert the main tube

No: Unfortunately, the top component of the locking assembly has shifted during transport and needs to be pushed back in. Use a rubber mallet or similar on the parts between the screws as indicated by the arrows. Alternate striking points in a cross pattern, gradually pushing the whole component down.

Step 21:#

Insert the main tube (F) through the center hole of the locking assembly in the table, with the chamfered edge of the main tub facing downwards.

Step 22:#

Gradually tighten the screws of the locking assembly in a cross-pattern order as indicated in the picture.

First: tighten all screws hand tight with the screwdriver handle.

Second: tighten all screws to 8 Nm with the torque wrench.

Third: tighten all screws to the final installation torque of 20 Nm with the torque wrench.

Step 23:#

Locate the marked position on the gear in the table assembly. (Red permanent marker)

Step 24:#

Install the rotary disk filler (D) with the M5 countersunk screws (E) at the indicated location of the gear in the table assembly.

Step 25-27#

Run the loudspeaker cable (A) through the main tube with the speak-on plug facing downwards and the banana plugs facing upwards.
Attach the extension adapter (C) and the loudspeaker extension cable (B).
Run additional cables in the same manner if needed. (for example XLR, RCA or power for active speakers)

Step 28#

The stand must now be adjusted to so that the main tube is in a vertical level. For this purpose, the nuts on the brace stumps are used.

Nut 1: Used for level adjustment.

Nut 2: Counter-nut used to fix nut 1 after adjustment.

Nut 3: Fixes thread in the brace stump. No further tightening needed.

Step 29#

Gradually tighten the upper nuts (nut 1) of the cross braces on all 4 sides, so that tilting of the table is no longer possible.

Step 30#

Check the incline of the main tube using the spirit level. Measure on all 4 locations (0°, 90°, 180° and 270°)

Step 31-32#

Adjust the main tube incline to the horizontal level if needed with the nuts of the cross braces.
Adjust the tension of the upper nut 1 on two opposing cross brace to adjust the incline as shown in the example picture.

Attention: Always decrease the tension of the nut on one brace before increasing the tension of the opposite brace.

Step 33-34#

After adjusting the incline of the main tube, counter the upper nut 1 of each cross brace with the second nut 2.
Use a second 13 mm combination wrench to tighten nut 2 while holding nut 1 with the first wrench.

Step 35-36#

Loosen the screws on the second profile connector inside each cross brace and slide them also down into the brace stumps.
Tighten all screws in all of the 8 profile connectors.
