  1. Flip the two levers up, one at a time.
  2. Twist the two levers out.

To Close

  1. Place the wire carefully under the retaining arm. The wire must exit through the groove in the clamp.
  2. Place the two halves of the clamp back together so that the wire is held gently in place. Do not squeeze them together hard.
  3. Twist both the levers in, one at a time. Twist both levers before attempting step 6.
  4. Flip the levers over to seal the clamp.

Important Notes

Cases with this clamp are for surface use only, but will offer protection from temporary submersion. They are not recommended for prolonged submersion.

When not using the case leave the TC clamp open. If not the wire could eventually cause a permanent distortion of the foam, risking leakage.

As long as you follow this instruction the clamp will be watertight with or without a wire.

The maximum thickness of wire around which the TC clamp will seal is 1/10th inch (2.5mm).

Here are a couple of videos where Brazilian sound director Gui Algarve used our waterproof bags to get the sound:

    Hi, my name is Gui, I am a sound mixer from Brazil. I would like to thank Aquapac for the quality of its products. I use the Aquapac 158 to protect my wireless microphone systems. I used a Sound Devices 788T recorder, wireless Lectrosonics systems, transmitters placed inside the Aquapac were model UM 400 and waterproof microphones Countryman B6. The Aquapac is very built, excellent quality materials, fast and easy to handle, open, close, and I felt very secure in place the transmitters in the water.

  2. Kelley, CA, USA

    I have the 558 and a 158 and they are both great products.
