Bose QC45 Aviation Microphone
Tusen takk (which is thank you in Norwegian ) – for purchasing the Avee
aviation microphone ! We hope it gives you as much joy flying with it – as it
gives us designing it – and flying with it!
In this leaflet we will show you how to prepare and connect the Avee
microphone to your headset – and how to use it.
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. You can also scan the QR-code in the upper left corner of
this page to get a video on how to do it.
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 (the one
already installed on the Avee) 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.
Make sure using only one magnet stripe.
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:
- 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.
- Attach the Avee microphone to the headset. Make sure the Avee microphone is clamped safely to the headset.
- 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.
- Switch on the ANR feature on the headphones. Please note that you will always have audio in your headphones regardless of headphone battery level or headphones ANR status and The Avee microphone output is NOT affected by headphone battery power level.
- 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.
- The internal Bluetooth® available in your headset 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 product.
Headphone volume setting
On the Bose™ QC45 the headset volume can be adjusted from the headset itself
using the +/- keys on the right earcup. Please check out the user manual for
the QC45 for detailed info.
Please note that for most pilots the normal procedure for adjusting the
headphone volume is by setting the 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 levels in the back seats are following the level set by the co-pilot.
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 and
your finger nail or the corner of a credit card as a tool.
Level 9 is maximum and level 1 is minimum level. Factory setting level is 3.
Avoid setting the output level to high. This will make the noise cancelling
microphone in the Avee pick up unnecessary cockpit/ambient noise and the
signal might saturate.
Headset mono & stereo mode
The Avee microphone is set to the mono mode (factory setting), by turning the
mono / stereo adjustment knob fully to ‘M’. To set stereo mode, turn the
adjustment knob fully to S. Please note that most aircrafts have a mono radio
& intercom system. If you set the Avee to stereo mode in an aircraft with mono
support, you will loose the sound in the right earcup.
Problem solving
-
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 basic rule is that when you hear yourself well in the intercom, ATC and other aircrafts hear you well. However – the aircraft intercom and the radio are usually two separate and independent systems and they behave differently. -
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. -
Audio in left ear only:
The Avee microphone is set to stereo mode. Set to mono mode to fix this issue.
