Samson MIXPAD manual Signal Ground

Connecting the MIXPAD -

General Suggestions

•Make one connection at a time and then monitor the incoming signal. If you hear a distinct hum or buzz, you may have a grounding problem with that particular device. See the section in this manual entitled “Grounding Techniques” (on page 26) for more information.

•NEVER connect a microphone and line level input to the same channel simultaneously—use one or the other. You can have some channels connected to microphones and others to line level signals (for example, you might want to plug mics into channels 1 - 2 and line level signals into the remaining channels)—just don’t have both kinds of inputs connected to the same channel. The diagram below shows how your mic connectors should be wired:

1 GROUND TO MIC

2 + SIGNAL

•For easy control over a pair of matched signals (i.e. the left-right outputs of a stereo effects processor, keyboard, drum machine, tone generator, CD player, or tape recorder), use the MIXPAD’s stereo input channels. The Balance control in these channels will allow you to adjust the relative levels of the two inputs, and you can also equalize the stereo signal, with the same EQ settings applied to both inputs.

•There are additional “hidden” (or at least not so obvious) stereo inputs to the MIXPAD; these are the Aux returns. Use these whenever you want to bring in a stereo signal that will not need to be equalized. Bear in mind that the two stereo Aux returns in the MIXPAD 12 / MIXPAD 9 can also be used as four monophonic returns and that the single stereo Aux return in the MIXPAD 4 can also be used as two monophonic returns (when connecting only one monophonic signal, use the “Aux Ret. 1/Mono” jack so that the returning signal is automatically panned dead center).
