I have been thinking about the audio system for my 2 place  IFR airplane.  Have looked at the audio info presented in Bob's book and am  not sure if the systems depicted will satisfy my needs/wants.  The aircraft  will have 2 NAVs, 2 COMs, Glass panel (GRT EFIS), and GPS, along with a music  channel input.

  

 1.  I would like some elaboration on Bob's system, as  to advantages and disadvantages.

  

 2.  Does anyone have any experience with the RST  unit? 

  

 Comments, suggestions, helpful hints  requested.

If your music is planned to be in stereo - that might impact your audio panel selection.

    I'm not sure what you're referring to as a 'system'.

    I've described a variety of ways in the book and

    in the instructions for the DIY audio isolation

    amplifier that offers a wide range of options.

    Those options will range from one radio and no

    intercom to a panel full of radios, stereo

    entertainment . . . and if the companion

    intercom is so fitted, up to 4 seats.



    What are YOUR requirements? How many different

    audio sources do you anticipate? If there are

    warning signals from the efis  and gps systems,

    then you may need to mix up to 6 different

    sources with stereo entertainment on top of

    that.



    You can add more inputs to the device I've

    described and it will handle stereo music.

    There are sources for audio isolation amplifiers

    that have more inputs also. Which intercom

    are you looking at? It may have stereo mixing

    features too and you then may only need a

    mono-version of the audio isolation amplifier

    which would provide all the inputs you'll need.



    So it's not "bob's system" that has advantages/

    disadvantages, it's YOUR system that describes

    design goals that must be met whether you use

    any data from the 'Connection or any other

    source.

You might also consider one of the pre-built, inexpensive, Audio mixers made for aviation use. I purchased a CS-408 unit (aprox. $100) from Precision Instrument & Control, Inc. (Ft Worth, TX).  I needed to mix my Nav, coms, and various warning audio signals in my LongEz. Frankly, I have not yet tested the installation. However, the unit seems perfect for me. It is very small, well built, and can mix/equalize up to 8 channels. 



I think there are a couple of other similar products out there, but can't remember the sources.

    There's a List member who offers a multi-channel

    mixer and as I recall he offered channel-by-channel

    gain potentiometers too. See:

Hello Dick  

   

I do not know about this unit, but I purchased and installed the Audio Mixer AMX-2A from Vern Little, and it works as advertised.  

It is small, light, and perfectly suitable for the job. Nowadays (not when I bought it) it is not cheap though.

Have a look at http://vx-aviation.com/.

The AMX-2A supports 10 channels, with volume control for four channels. 

Works with any intercom or comms radio without additional components and is 

very small and light.  We take PayPal and shipped from stock, free shipping 

anywhere in the world.  Similarly packaged gizmos support music players and 

cell phones (or both).



Thanks, Vern Little

Thanks to all who responded.  Unfortunately, I do not need a 10 channel 

mixer and certainly can't see spending $160 for about six channels more 

than I need.



I am perfectly capable of designing and building my own but I was hoping 

to find a simple, cheap solution.

   We still offer boards for this DIY

   audio isolation amplifier that can

   be fabricated in both mono and stereo

   versions.  We've sold about 50 boards

   over the past 10 years and have received

   no reports of difficulties getting it

   assembled and integrated into the

   builder's project.

 The link(below) won't work for me, neither does accessing your catalog at  your AeroElectric web site

 Can you steer me in the right direction

Dick;  

   

Both the website catalogue and the provided link work fine for me. Must be something with your computer or e-mail programme, it’s not Bob’s documents.  

Here’s the link pasted from my computer. See if it works better than the original.

Someone asked where to get the unit I suggested. The CS-408 unit is from Precision Instrument & Control, Inc. (Ft Worth, TX). The company sells these directly. They are an electronics OEM for several aircraft manufacturers. I'm away from my files so can't provide the phone number, but they are probably listed in the phonebooks. Harvey is the main contact there for this product. Between the CS-408, the VX unit, and the Aerolectric unit, there is no longer any excuse for not having an almost invisible "audio panel".
