Samson PL2404 - Manual (Page 7)

Guided Tour - Channels
fully clockwise, only the even-numbered (right) input signal is heard (panned
hard right). When only the odd-numbered (left) input is connected, the Balance
knob functions as a constant level Pan control, allowing you to continuously
place the incoming signal anywhere in the left-right stereo field. For more
information, see the “Using the Balance Control” section on page 18 in this
manual.
6: Level (white) - This knob (purposely made a little bigger than the others so
you can find it easily in low-light situations) simultaneously controls the volume
of both the odd- and even-numbered channel inputs (the relative volumes of the
two can be adjusted with the Balance knob, as described in #5 above). In
practice, you will use the Level controls to continuously adjust the loudnesses of
the various signals being blended together by the PL 2404. The “0” (2 o’clock)
position of the knob indicates unity gain (no level attenuation or boost). Moving
the knob counterclockwise from the “0” position (towards “
∞”) causes the signal
to be attenuated (at the very bottom, it is attenuated infinitely—in other words,
there is no sound). Moving it clockwise from the “0” position (towards “+10”)
causes the signal to be boosted by as much as 10 dB.
For best signal-to-noise ratio, all Level controls for channels carrying signal
should generally be kept at or near the “0” position. Channels that are unused
should have their Level controls kept fully counterclockwise at their “
∞”
(minimum) level. See the “Setting the Correct Gain Structure” section on page
13 in this manual for more information.
