A-FILTER Installation

The A-FILTER for Balanced Microphones adds RF immunity for microphones, specifically when connected to digital wireless transmitters like the A10-TX.

The instructions below describe how to mount the A-FILTER for Balanced Microphones into a female XLR connector.

Before starting please make note of the following:

  • The A-FILTER should be placed as close to the microphone as possible. The benefit of the RF filter is significantly reduced if placed downstream of the microphone connector.
  • Make certain to use high-quality XLR connectors. Inexpensive connectors, including many painted XLR connectors, do not provide adequate electrical contact between the connector shell and the microphone connector.
  • The A-FILTER does not degrade the audio signal, affect phantom voltage, or draw any power in any way.

Supplies Required

  • The A-FILTER RF Filter for Balanced Microphone.
  • High quality female XLR connector. The circuit board was designed with Neutrik NC3FX connectors.
    AC-BALXLR (blue cap) is not compatible with the A-FILTER. AC-BALXLR-2 (black cap) already has the A-FILTER installed.
  • Solder and tools for cable assembly.

Note: Installing the A-FILTER assumes knowledge of proper cable soldering and termination.

Step 1

Disconnect the XLR female connector and cleanly unsolder the existing cable from the insert. If this is a new cable assembly, this step is not necessary.

Step 2

Solder the A-FILTER circuit board to the cable. Take note of the polarity labeled on the circuit board. Solder the ground connection to the square thru-hole pad.

Step 3

Solder the A-FILTER circuit board to the connector insert. Make certain to align the connector pins with the labeled solder pads on the board.

Connect pin-1 of the connector to the insert’s shell tab.

Step 4

Carefully slide the chuck over the A-FILTER circuit board.

Step 5

Place the connector housing and finish the installation by sliding the bushing to the housing and turning to secure.

Sound Pro Ronan Hill on the A10 Wireless System

5 July, 2018, Rickmansworth, UK — Production sound mixer Ronan Hill, CAS, has received four Primetime Emmys and five Cinema Audio Society awards for his work on Game of Thrones.  Audio Ltd. recently asked him as a longtime Audio Ltd. customer, what his thoughts are on the new A10 Digital Wireless Microphone System.

He was kind of enough to respond from the set of Season 8 of Game of Thrones. 

“For someone who loves the sound of a boom mic on a cable, the Audio Ltd A10 is a remarkable piece of kit which sounds every bit as good. The main reason for being on a cable is ultimate control. You can adjust the level of the coarse gain on a mixer channel preventing overload of the preamp and set a level within the range of the channel limiter.

“When using an A10 on a boom the first thing you notice is how transparent the sound is. There is no additional noise or transmitter or compander artefacts, just pure sound. The body pack transmitter has built in phantom power which keeps it light on the pole. When you are working on a show like Game of Thrones you are dealing with scenes which vary wildly in performance level and scale. The A10 has handled comfortably anything we have thrown at it.

“For peaky scenes you can reduce the level on the transmitter and increase it on the desk without any discernible difference in noise (on my Cooper 208) and with a decent analogue limiter on the A10, you can retain the natural sound of clashing swords. On a walk test the A10 significantly out performed an Audio Ltd 2040. The distance you can deploy the mics is well beyond the feasibility of running a cable on an exterior set with cameras looking in several directions and when you add to this the speed and flexibility of set up change with the bonus of onboard recording, you have all the bases covered.”
