How can I connect my stereo mixer to a computer sound card for recording?
We recommend using the main outputs of the mixer to send signal to the inputs
of the computer or sound card. You will need to investigate which type of audio
connector your sound card uses and you will probably need to obtain some adapter
cables. You should be using the "line" level inputs on the sound card.
Be careful not to use the sound cards microphone input, you might get some signal
but it will not sound very good!
Depending on the configuration of your mixer, you can use a stereo channel
input, a "stereo aux return", or the "tape in" connectors
to feed the output of the sound card back into the desk. As before, you will need
to use the correct type of adapter cable. It is essential to check the routing
of this input, otherwise you risk creating a feedback loop. You should refer to
the instruction manual of the mixer for more details about routing the inputs.
To monitor your recording, your console is equipped with an extra output section,
which is labelled "control room / phones". This output section has it
is own level control, and its own routing switches. Certain models are also equipped
with a "pfl/solo" function - which opens up more flexible monitoring
possibilities. This function is explained in more detail in the instruction manual.
With regard to the main supply of electricity - it is a very good idea to use
a multiple connector socket to supply power to all audio devices, including the
computer and screen, from one mains receptacle. The majority of domestic supplies
will deliver the necessary current. This layout will reduce the likelihood of
creating earth loops in the audio system. Computer monitor screens should be kept
away from audio devices like active loudspeakers or electric guitars. If you still
cannot eliminate mains hum - you should connect a DI box in the audio path between
the mixer and the sound card.
