Frage von heinavesi:
Hello of a helpless EX3 users:
In the Audio menu there is a bar with TRIM options to adjust the sound level appears between-11dBu and-47dBu.
I am completely at a loss what to serve and what should I choose there. Even the manual makes me rather unfortunately in the rain.
Those who "saves" me?
Thank you!
Antwort von Jogi:
These serve to align the different sensitivities of external microphones.
Antwort von heinavesi:
Aha!
And how can I tell them? For example, a Rode NTG-1.

TRIM ADJUSTMENT
The other change in the AUDIO INPUT settings is quite baffling. This time, it's in regard to the TRIM function. The TRIM Allows you to increase or decrease the SOUND coming into the camera before it gets to the normal setting LEVEL controls, and is especially useful if you wish to operate a mic in the AUTO setting. Using the TRIM, you can pre-set s.average level for a particular microphone, thus enabling good levels in the AUTO mode.
Audio level is measured in decibels (db) and TRIM operates by moving to the minus (-) or plus (+) side of '0 'db. On previous models, to increase the level coming in, using the TRIM function, you changed the setting in the MENU to a higher number like + 6db INPUT and to decrease the volume, you would set the TRIM to - 18db or-6db. Note that - 18db volume is less than-6db. I know that this had been confusing to some people until they realized that it is a minus (-) number.
This is where it becomes strange. On the SonyEX1/EX3, when you alter the TRIM from-23dB to-53dB, it actually INCREASES the volume coming into the camera. I can only assume this was done to try to avoid the earlier confusion. I'm afraid that this attempt failed, and it has only added to the confusion.

My opinion: Let the setting to its default value. For us this has changed and no one ever car seems to work, although there is a tendency to be rather quiet recordings. That does not bother, because this overload is effectively prevented and the noise is not audible more.

Antwort von carstenkurz:
The sensitivity of the data can of course not 1:1 configure the camera. which is related to 1V/Pa @ 1kHz, plus the direct equivalent has Sonykein.
But of course, can be a reasonable level for a particular microphone and verify united s.ein some real shooting situations. This relieves one, of course not the usual level of control or protection, such as AGC or Limiter.
I think it is at least possible that has Sonyeine purely digital operating level control and the trim is the only analogous action scheme. In that case I would stop those already at a 'reasonable' value.
When I compare the values of times with another microphone, I would stop at the Sonyals clue mal-36dB. Lower values (ie, direction-47dB) would cause increased noise and increases the risk for Verzerrrungen.
