I always was one of guys who likes to build installation of multiple sound standards in one DOS game machine. Most problem here is to take joint signal, it must be as clean as it possible. Usually people connect cards through LINE OUT -> LINE IN -> LINE OUT -> LINE IN -> LINE OUT tracts and get a lot of unwished noises and sometimes signal damping.
If we have one card which can receive all other signals and mix them with nice (at least satisfactory) quality it will be great and we will not need external mixer. In case if you're using one machine the internal mixer is much more comfortable than external mixer, even with MIDI modules. If you use multiple retro machines the external autonomic mixer is more comfortable of course. This topic is about it. Now I present DOS mixer for EMU10K1 (Live!) cards and EMU10K2 (Audigy) cards which is made by my order. It includes enabled signals:
- analog AC97 -
LINE IN stereo
CD IN stereo
TAD mono (perfect for ADlib or Covox!)
MIC IN mono
BEEP IN mono
- digital -
SPDIF0 = CD SPDIF
SPDIF1 (reserved on Live cards, used on Audigy cards)
- analog LINE IN2, AUX2 -
I2S0 = AUX 2 stereo
I2S1 (reserved on Live cards, used on Audigy cards)
I2S2 = LINE IN 2 / MIC 2 stereo
All these input channels can be routed separately and independently to:
SPDIF0 (digital front)
analog rear + SPDIF3 (they always work together on Live as one channel, on Audigy they are separated)
SPDIF1 (digital cen/bass)
Of course each channel has its own customizable level. If you connect 5.1 system for Windows you can in DOS route one input channel to front, other to rear, or mix them together to front or rear. As you wish!
Also mixer has "digital output only" mode.
