 |
|
My PS engineering 6000 (mfg for UPS AT as the SL-10 MS) intercom has stereo
audio inputs and outputs. The other day I was flying and finally plugged in
my Sandisk mp3 player to enjoy some music while working my airspeed
calibration runs. I had the Sandisk volume set at maximum and had to have
the volume on the PS 6000 at 3/4 maximum to hear the music at a low level.
Also the music sounded a little distorted (not too surprising given the
volume setting on the 6000). I was hoping that there would be a pot on the
circuit board that I could adjust to increase the input sensitivity but
couldn't find anything in the manual about it. The system is set up for
stereo but right now I'm running the mono Sigtronics headset that I
purchased during my "Cessna" days, I have the volume on the headset at
maximum when doing the above test. The 6000 manual says it's ok to plug in
mono headsets so I doubt that the system has been damaged in any way.
Anyone have some words of wisdom on running mp3 and other audio input
devices with aviation intercoms and audio panels? I assumed the audio
inputs needed high level (not speaker level inputs) but maybe the Sandisk
just doesn't have enough oomph. In the short term I plan to convert the mono
headset to Stereo, long term I plan to purchase an ANR Stereo headset of
excellent quality (and unfortunately price). Please advise. Thanks.

I have the PMA7000MS (UPSAT SL15). When I was going through the integration of my stereo system, I remember reading the requirement for low level input:
"NOTE: Use the low level output of any entertainment device to connect to the audio
panel. Maximum signal level is 2 VAC p-p.
DO NOT use a speaker-level output, this will cause internal damage in the audio panel."
There is a minimum power requirement for operation though:
"The audio signal at the entertainment input must be a minimum of 500 mV P-P per channel for optimum music performance."
The first one of these criteria was a limiting factor in my selection of audio inputs...I have a Sony AM/FM/CD/MP3 player attached to my audio panel (as it output the corect voltage levels)...the Sony has inputs to take iPods or whatever else so I am adding that type of equipment through the Sony.
