Title: Recording TOO soft...
Post by: wizzzard on August 08, 2006, 04:39:22 PM
I just plug my H340 in my Mixer to record a dj set, but it's sooooooooo soft! And I can't find any recording settings so that I can change the input level.

With my iRiver OS never had any problems..

You can adjust gain right on the recording screen.

On the recording screen, use up/down to move through the settings you can change on the fly (currently volume (monitor) and recording gain).

On the line you want to change, use left/right to change.

To change source or access other recording settings, press A-B to go to the recording settings menu.

You'll see that, unlike your iRiver OS, you can:
- see the recording levels
- change gain on-the-fly
- have access to the complete gain range the hardware supports, which is far bigger than what iriver wants you to use.

As a tip, don't use too much gain, try to adjust the input level so you can work in the 0-10dB range. Above 20dB the pre-amp may get a bit more noisy...

First.. Thanks for the reply's.. It's getting a little less fuzzier every minute.. But still don't get some things here.

What I do get is that:

In the recording Screen I can ajust the GAIN and the output level. Ofcourse the gain isn't the best way to ajust a record level..  :-\

so Petur you wrote:

But where can I ajust this? The only options in my "recording settings menu" are:

- Sourse
- File Split Options
- Prerecords Time
- Dir
- Show Rec Screen on Start Up
- Clipping Light

Thanks for the help you all. Rockbox is great!

Volume = output level to headphones for monitoring
Gain = recording level (this adjusts the pre-amp that sits before the ADC)

So you need to change the gain to adjust the signal that goes to file. Use the peakmeters (right above the volume line) to see what levels you're getting.

So the gain IS the only way to control the input level with Rockbox! I'll try that. Thanks!

by the way: what is ADC?
