The outer knob acts like an input trim knob on a mixing board. The hotter the input the lower the setting. For line level or a line level board feed
the knob should be set close to zero. For mic level it should be set closer to high noon. The outer knobs should never be moved during recording.
The inner knob acts more like a fader on a mixing board. Minute adjustments can be made there if necessary.
Well, that's all good and fine, but now you're just talking smack.
I'm sure you are all way more knowledgable than me, but those 2 dials (inner and outer) are all you get to adjust the levels, so I HAVE to be able to adjust ONE of them.
"Adjusting the input levels
1. Turn the Input level knob [SENS] (outer) all the way left.
2. Turn the Input level knob [LEVEL] (inner) to the center position. This position is 0 dB.
3. Hold down the [PAUSE] button and press the [REC] button.
The R-44 enters recording standby mode. During recording standby, the [REC] button blinks
and the indication alternates between REC and STANDBY.
4. Play the sound to be recorded into the microphone.
Gradually turn the Input level knob [SENS] toward the right.
Sensitivity has 11 steps of +4, -2, -8, -14, -20, -26, -32, -38, -44, -50, and -56 dBu.
* When the channel name display reverses, the input level has reached the clipping level. Set the knob
to the position just before the display reverses. "
Ack!
This is just too confusing...
