 Posted: Fri May 22, 2009 3:39 pm Post subject: Comm 2 volume Very low |
 |
|
My Com2 Garmin SL40 which is connected through a Garmin 340 audio panel
produces only a fraction of the volume, that the Com1 SL 30 does. I've
been through the manuals looking for a clue as to where to begin. The
audio panel states that the volume is controlled by the volume control
on the radios. The Comm2 Vol is at max level. Anybody got suggestions on
where to look?
THANKS

Deems,
I had the OPPOSITE problem but the solution may be the key for you... See
below.
"For some reason the SL40 com is much louder through the intercom when
transmitting than the GNS430W com even with the volume turned down as low as
possible."
You can tell him that's "bad" setting in SL-40 for the side tone. It should
be set to "000" - by going into setup mode then jumping through a few
settings until side tone setting is encountered. When set to 000, the side
tone volume will "follow" whatever volume is on the volume knob. Currently
it's set to some value other than 000 (most likely 128) and that's why it's
not following volume knob at all.. (all this is in the manual J). Fixed
that on Thane's plane just the other day.. he had exact same thing going
on..

Bret, Thanks for the suggestion I stopped by the hangar this afternoon,
and made the changes to the 'sidetone' on the SL40 Unfortunately there
was no difference in the Volume level through the audio panel.
Does anyone think this might/could be related to antenna/coax? I'm
trying to eliminate the easier things, as getting to the connectors and
pins is going to be some serious access challenge.
