Subject: [TenTec] Omni V vs. Headphones
| Recently, I connected my Kenwood HS-5 headphones to my Omni V. There
is a
| noticeable rumble in the audio. The level of this rumble seems to be
| independent of the AF Gain setting. In fact, with the AF gain at
minimum,
| the rumble is still present. If I partially remove the headphone
plug, so
| that the speaker is again active, but there is still audio in the
| headphones, the rumble completely disappears.
|
| I tried a Heil ProSet Plus headset. It does not exhibit the rumble,
even
| when the speaker is muted.
|
| I suspect that this is an impedance issue. The impedance of the
Kenwood
| headset is 8 ohms. The Heil is 200 ohms.
|
| Is there a simple fix that could be made into an adapter cable that
would
| allow the Kenwood headset to be used?
