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.
