Line-In slider haves no effect

maxxa · Sep 23, 2006, 09:46 AM

This is my first post so,
hello to everyone on this forum!

My AC97 line-in slider haves no effect on input level of my guitar.. I can hear my guitar trough asio [using guitar rig 2 standalone] even if everything in AC97 mixer is MUTED, every single slide.. Not shure what makes this problem. I want to incrase input level of guitar, but not via "ins and outs" or "recording" sliders. They are at zero.

i'm using 3535 kx drivers
and here is how my DSP looks like.. maybe there is a problem..

Appriciate your help,
cheers

Confirmed - but Im not so sure this is a bug...

Youll see this happen if LINE IN is selected in the record source drop down.
But if you set that to 'Stereo Mix' - the mutes and levels will work on the AC97 KX mixer page.

I am pretty sure that is how it is supposed to work (at the AC97 codec level).
The sliders on the bottom of the AC97 page, control which sources are enabled in the AC97 mixer. The AC97 mixer is only enabled for recording, when Stereo Mix or Mono Mix is selected as the AC97 source.

Using your setup (from your picture), you should use the AC97 slider on the Ins and Outs page, and the Analog Recording Gain slider on the AC97 page to adjust the level. Beyond that, you can add additional gains within the DSP chain, but it is better to start with a good level (i.e. use a pre-amp/DI-Box or something, before connecting it to the sound card, if the signal is too weak).

BTW: Why are you using 3535?

Russ, you're correct about "stereo mix" and rest of the sliders. Thanks for help. хвала на помоћи

I couldn't find is Analog Recording Gain slider on AC97 page?

Yes, I run my guitar trough valve preamp "Behringer Tube Ultragain MIC200" are you familiar with quality of these? I never used classic DI Box so i can't compare.

I made mistake, on my skin is written 3535, but my drivers are 3537, sorry.

The Analog Recording Gain slider, is the one labelled "12" in the following picture:

(the tooltip for the slider reads "Analog Recording Gain")

Regarding the pre-amp, I do not know anything about it, sorry...

A DI box usually only converts impedances and/or signal levels.
'valve preamp' - infers 'emulating' how it should sound after the signal goes through an amplifier and speakers. (Aka 'Amp and/or cabinet simulation' - or in the case of a mic rpreamp - emulating a tube preamp)

Berringer is (IMO) considered closer to consumer grade than professional (like Evintide /TCE/Lexicon) - but some may argue their brand to be 'pro-sumer' (somewhere in between) - such classifications are a result of who it is buying them. Their popularity is from their generous 'bang for the buck' factor - but rarely seen in 'real' (professional) because of their lacking in some major technical specs that are paramount in a pro studios - but often comprimised in a home studio due to budget.

In other words - theres better - and theres worse. (JUST going by the berhinger name - with out having used THAT model in particular - my limited exposure was with their Ultra-Tube (or something to that affect) processor and some other non-processor equipment - and was OK - GREAT for $$$ - which is a sort of a 'disclaimer')

My guess; its A/D convertors and/or its DSP (?? if it has one) are not as good as 'pro' units of similar function.
