Description

K&M 23840 · Reference 23840-300-55

The microphone in front of you,
the desk clear.

The König & Meyer 23840 arm clamps onto the edge of a desk and carries a microphone, a tablet or a smartphone up to 0.8 kg. Its three sections, balanced by springs, bring it up to 820 mm from the clamp.

  • 820 mmMaximum reach
  • 0.8 kgTotal load
  • 51 mmBoard or tube
  • 4Cable clips

Springs that act as a counterweight

Without a load, the springs pull the arm upwards: that is its starting position. The weight of the microphone balances this tension, and K&M states that the mechanism works best with a load close to 0.8 kg. Three knurled nuts at the joints add just enough friction to stop the arm moving on its own; once the balance is found, it moves without loosening them.

A clamp for a board or tube

The table clamp grips a board or tube up to 51 mm. Its metal frame, fitted with plastic inserts and a non-slip support, is shaped to hold on a smooth surface as well as on a round tube. The arm's rod fits into it, is oriented, then locked by a knurled screw.

Supplied without cable, ready for yours

The arm has no built-in cable: you run the one that suits your microphone, held by four clips that attach to the profile and then slide along the arms. The 3/8" and 5/8" connectors accept both common clip threads.

Hold the arm before removing the microphone or loosening the knurled nuts: without a load, the springs pull it sharply upwards.

Frequently asked questions about this product

Is the microphone cable built into the K&M 23840 arm?
No: the 23840 is supplied without cable, so you can connect the one that suits your microphone. Four supplied clips hold the cable along the arms; they clip on where you want and then slide to follow the movement.
What kind of desk does the clamp fit?
A board or tube up to 51 mm thick or in diameter. Its metal jaws, lined with non-slip plastic, are shaped to hold on a smooth surface as well as on a round tube; K&M also offers a table flange 23855 and a wall mount 23856.
How heavy a microphone can the arm hold?
Up to 0.8 kg in total: a microphone with its clip, a tablet or a smartphone. K&M states that the spring mechanism works best with a load close to that 0.8 kg, which balances the tension of the springs.
Why does the arm spring up on its own without a microphone?
Its springs pull it upwards when it is not loaded: that is its starting position. Before removing the microphone or loosening the knurled nuts, hold the arm by hand, because the three knurled nuts at the joints are not enough to hold back the force of the springs.
3/8 or 5/8 inch thread: which one to choose?
Both are provided: the 23840 offers a 3/8" connector and a 5/8" connector, and you choose the one that matches the clip or holder before fitting the microphone. It therefore suits clips with European as well as American threads.
What reach does the K&M 23840 arm offer?
Up to 820 mm of reach, for a length of 460 to 960 mm. The arm is made of three sections of 500, 460 and 60 mm, jointed and balanced by springs, which are positioned by hand and then locked by three knurled nuts.
