ISOMAX 4RF Mount (A4CDM) Installation Guide

Because of the Countryman ISOMAX 4RF’s Active Vibration Isolation technology, the ISOMAX 4RF does not require a bulky

shock mount to protect against handling and table noise. The A4CDM is our simple, low-proﬁle mount for desks or podiums.

The A4CDM mounts with a single hole; these instructions will help you securely install the A4CDM in a matter of minutes.

1. Plan Your Installation

The diagram to the left shows a typical podium installation:

• A cable runs from the mix board in the control room to a panel in the oor

near the podium (1).

• The male side of a short XLR cable (2) runs from the oor panel through the

nut (3), then through a 7/16” hole in the top of the podium (4), then through

the lower half of the A4CDM (5), and ﬁnally the wires are soldered into the

upper half of the A4CDM mount (6).

• The lower half of the A4CDM screws on to the upper half of the A4CDM.

• The nut screws on to the lower half of the A4CDM, clamping the A4CDM

ﬁrmly in place.

2. Prepare your tools

You will need:

• An XLR cable long enough to reach the mix board or nearest audio port.

• A soldering iron and soldering supplies.

• Wire strippers / cutters

• A 9/16” or adjustable wrench

• A drill and a 7/16” drill bit.

• Electrical tape OR heat shrink and a heat gun or torch.

You may also want to have:

• A multimeter to test for shorts or breaks in your wire and solder joints.

• Pliers, tweezers, or other tools to aid in soldering

3. Prepare the wire • Remove the female end of the cable and cut back the outer insulation • Strip the ends of conductor wires and twist each pair together. • Twist the shield wires into two bunches: one will usually go to Pin 1 of the XLR cable, and the other will go to the tab connected to the outer shell of the connector. Be careful not to leave any stray strands which could create shorts later. • If you are using heat shrink, place it on the conductor wire pairs. 4.

8. Assemble the A4CDM Screw the threaded rod firmly into the lower half of the A4CDM. Hold the upper half of the A4CDM, slide the lower half along the cable and screw it into the upper half. The cable should not rotate as you turn the lower half of the A4CDM, and the A4CDM should close securely. The most common reasons for the A4CDM not closing are too much electrical tape or wires which are too long. 9. Slide the A4CDM through the hole This is a good time to rotate the A4CDM to face the desired direction.
