How to prepare your headphones

The Avee microphone is using an adhesive magnetic stripe to attach safely to your Bose^® or Sony^® headset.

This solution makes it easy to attach and detach the Avee microphone from the headphone in seconds, and the Avee microphone stays safely in place whenever it is connected to the headphones.
Please follow these instructions to install the magnetic stripe properly to your headphones.

Step 1: Using the cleaning wipe supplied, clean the base of your headphones including the area surrounding the input jack. Ensure that you remove any residue that is adhered to the headphones. Let dry for a minute or two.

Step 2: We are now preparing to transfer the magnetic stripe to the headphones using the Avee microphone as a jig. Let the magnetic stripe be attached to the Avee microphone, and remove the adhesive stripe protective backing from the magnetic stripe.  The magnetic stripe should stay on the Avee microphone and the adhesive side should be facing the headphone.
Check out this video on how to do it as well!

Step 3: Guide the add-on to the base of the left headphone and firmly press it in place for minimum 30 seconds. Once attached, carefully unplug it to reveal the adhesive magnetic stripe being transferred to the headphones.
Press firmly on the tape to ensure all edges of the tape have adhered to the headphones.
Optimally the adhesive on the magnetic stripe needs a 24 hrs curing time.

That is all – the Avee aviation microphone is ready to be used!               

Connecting the Avee microphone to the aircraft

To start using the Avee microphone in the aircraft, follow this procedure:

1. Plug the Avee aircraft interface cable into the Avee microphone using the angled USB connector. Use force to make the USB C connector go all the way into the USB socket. The connection may be done in two directions – either the cable pointing upwards – or the cable is pointing downwards.
2. Attach the Avee microphone to the headset. Make sure the Avee microphone is clamped safely to the headset.
3. Plug the Avee aircraft interface into the aircraft. Please note that the aircraft connector might be the dual GA, Lemo Redel, Neutricon or XLR-5 – all depending on what you have purchased from us & what is available in your aircraft.
4. Switch on the ANR feature on the headphones. Please note that you will always have audio in your headphones regardless of battery status or headphones ANR power on/off.
   The Avee microphone output is NOT affected by headphone power status.
5. When the aircraft radio & intercom is switched on, the mic add-on will get bias power from the aircraft. This is indicated with a steady dimmed Power indicator light on the bottom side of the Avee microphone.
6. The internal Bluetooth^® available in your Bose QC35^™ or Sony XM3/XM4 will automatically disconnect all units connected via Bluetooth when the Avee microphone is connected.
   To be able to listen to music or use your phone when flying, you need the Avee BlueLink. Check out our web pages for more info on this add-on product.

Headphone volume setting

Adjust the headphone volume by using the Volume knob on the Avee microphone.
Rotate anti clockwise for max volume and clockwise for minimum volume.
Please note that for most pilots the normal procedure for adjusting the headphone volume is by setting the Avee headphone volume to maximum – and then adjusting the volume from the aircraft audio panel.

In small GA aircrafts, the headset volume  is typically adjusted individually for pilot and co-pilot. Volume level in the left back seat is following the pilot volume level, while the right back seat is following the level set by the co-pilot.
In this case we suggest letting the back seaters adjust the volume level to lower level (if needed) using the volume control on the Avee microphone.

Microphone output level

The microphone output level is factory set to a normal output level, and will usually not require adjustments.
The output level may however be set by using the Mic level adjustment knob on the bottom side of the Avee microphone.
To adjust – please use your finger nail or the corner of a credit card. Maximum clockwise is minimum level while maximum anti-clockwise is maximum level.
DO NOT USE FORCE – and DO NOT USE A SCREW DRIVER !  
Avoid setting the output level to high. This will make the noise cancelling microphone in the Avee pick up unnecessary cockpit/ambient noise.

Headset mono & stereo mode

The Avee microphone is set to the mono mode (factory setting), by turning the

Mono / stereo adjustment knob fully anti clockwise.  To set stereo mode, turn the

adjustment knob fully clockwise.

DO NOT USE FORCE – and DO NOT USE A SCREW DRIVER !  

Problem solving

1. Bad ATC reception – reading you two
The most common problem for fresh aviators, is that the microphone is placed too far away from the mouth. This makes the intercom and radio pick up little or no audio from you, and this will of course lead to problems. Keep the microphone approx.  6mm from your mouth at all times – and let the flat side & white dot face your mouth.
A good rule is that when you hear yourself well in the intercom, ATC and other aircrafts hear you well.
However – the intercom and the radio are to separate and independent systems and they behave differently.

2. Intercom squelch setting.
   On most GA aircrafts intercoms, the squelch is set manually.
   If the first part of the word is clipped – or the intercom squelch is not opening at all – this must be corrected by adjusting the squelch threshold in the aircraft.
3. Audio in left ear only:
   The Avee microphone is set to stereo mode. Set to mono mode to fix this issue.

DISCLAIMER

Avee is an unlicensed third-party accessory and is not affiliated with Bose® or Sony®.
Bose® or Sony^® does not approve or endorse the products manufactured by Avee.

What is an TSO/ETSO approval

The TSO (US Technical Standard Order) and its European equivalent ETSO (European Technical Standard Order) authorization, represents one way (and not the only way) to have products, parts and appliances approved.
The TSO/ETSO  is an optional step in a design process which ensures that a part or appliance complies with a minimum performance standard.

Is the Avee Aviation Microphone TSO/ETSO approved ?
The complete headset solution with the Avee Aviation Microphone is not TSO or ETSO approved.
The reason for this is simple: as a manufacturer of the microphone part of the solution only, we do not have full control of the production line of the headsets we are adapting to (Bose & Sony) and hence: we can not obtain a TSO/ETSO approval.

The Avee microphone add-on itself is designed in compliance with TSO standards , while the Bose & Sony headsets most likely are designed according to different standards than the TSO.

This fact does however not mean that the quality of headset from Bose & Sony is higher – or lower – than headsets manufactured according to the TSO standards.

Their design standard is simply not TSO.

It is a fact that the quantity of high quality headset products coming out from Bose & Sony are far superior to the quantity of aviation headsets being produced.
Making low quality products would not be a good business model for sure, and the quality of Bose & Sony headsets is simply excellent.

Our competitors TSO approval

We do know that some of our competitors state their products are TSO compliant – or even have a TSO approval.

This might be correct for part of the product , but will unfortunately not apply for the complete headset solution with a Bose or Sony (non TSO) headset.

The complete system as ONE UNIT has to be approved  – from cable to ear cushions. This is not possible for aviation microphone systems like the Avee – or any other mixed system.

Who require the TSO approval
It is important to know that the request for a TSO approved headset is an airline request, and not a FAA request.
Headsets used by the pilots in aircrafts do not need a TSO or ETSO approval.

We estimate we sell around 90% of our products to commercial pilots, but we do see that the TSO requirement from airlines in the US is far more common than in airlines in the rest of the world.

Cable & connector wiring diagram
Several connectors are used in aircraft to connect the headset, and here we give you the pinout for the most common connectors we support at Avee.

The dual GA connector
The most commonly used aviation headphone connection is the dual general aviation connector, and these connectors are found in large commercial aircraft, from Airbus and Boeing – to general aviation aircraft like Cessnas and Diamond.
The advantage of this connector is that it is fairly affordable and widely used.
The disadvantage is that the two connectors are almost similar in thickness, and it is very easy to plug in the thinnest connector in the thickest hole; then to find that it was the wrong hole. More annoying than a real problem.
The dual GA contains separate pins for the left and right speakers, but this stereo support feature is almost never used in aircraft.

The dual GA pinout
The dual general aviation connector consists of two connectors;

• the 5.2mm connector, which contains the signals for the microphone and push-to-talk
• the 6.3mm connector, which includes the headset left and right (if available)
  .

The pinout is according to the following:

• Tip – 5.2mm connector
  Push-to-talk signal.
  Not connected on Avee cables
• Ring – 5.2mm connector
  Microphone +,
  Avee: red wire
• Sleeve – 5.2mm connector
  Microphone ground
  Avee: yellow wire
  .
• Tip – 6.3mm connector
  Speaker left.
  Avee: white wire
• Ring – 6.3mm connector
  Speaker right.
  Avee: green wire
• Sleeve – 6.3mm connector
  Speaker ground
  Avee: black wire
  .

The XLR-5 connector
The five-pin XLR-5 connector is used mostly in commercial aircraft from Airbus and some Boeing aircraft.
It is hardly ever found in GA aircraft.
The real advantage of this connector is that all headset signals are carried by one connector only (as opposed to the dual GA).
The XLR-5 does not support separate pins for the left and right speakers; hence it does not support stereo, but for all practical purposes, this is absolutely not a problem.
The XLR-5 has a separate pin for feeding (old) ANR with power. Our impression is that this is not a feature that is popular among the ( technical side of the) airlines, and Avee is not using this feature.

The pinout on the XLR-5 is according to the following:

• Pin 1
  Left and right headset speaker
  Avee: white and green wire
• Pin 2
  Speaker ground
  Avee: black wire
• Pin 3
  Microphone signal
  Avee: red wire
• Pin 4
  Microphone ground
  Avee: yellow wire
• Pin 5
  Not defined
  Avee: not connected
  .

The 174/U or TP-120 connector
The 174/U or TP-120 connector is a connector used mostly on helicopters, but we have even seen it on smaller commercial aircraft.
The connector has only four pins (hence; not supporting stereo), is tiny and rugged, and very simple to plug into the aircraft.
The disadvantage of this connector is that is rarely used and (extremely) expensive.
The fact that several pinout options exist for the same connector makes it somewhat difficult to cope with.

We support the US NATO / IMSA pinout which is according to the following:

• Tip
  Microphone ground
  Avee: yellow
• Ring 1
  Headphone speaker left and right
  Avee: White and green
• Ring 2
  Microphone signal
  Avee: Red
• Sleeve
  Speaker ground
  Avee: black
