Guided Tour - Channel
6: Equalizer (blue) - These knobs determine the amount of boost or attenuation
in each of three frequency areas. The high and low frequency knobs provide
15 dB of cut or boost at 10 kHz and 80 Hz, respectively, with shelving-type
control. The mid frequency knob provides 12 dB of cut or boost at 800 Hz, with
a bell (peaking) curve. A center detent in each knob (at the 12 o’clock position)
indicates no boost or attenuation (that is, flat response). As each knob is turned
clockwise from the center detent position, the frequency area is boosted; as it is
turned counterclockwise from the center detent position, the frequency area is
attenuated. For more information, see the “Using Equalization” section on page
17 of this manual.
7: Pan (green) - This knob allows you to place the input signal anywhere in the
left-right stereo spectrum, while keeping the overall signal level constant. When
the knob is placed at its center (detented) position, the signal is sent equally to
both left and right outputs. When moved left of center, less signal is sent to the
right output and more signal is sent to the left output, making the sound appear
left of center; when moved right of center, less signal is sent to the left output
and more signal is sent to the right output, making the sound appear right of
center. To route a signal hard left or right, place the pan knob either fully
counterclockwise or fully clockwise.
8: Line input connector - Connect line-level sources (such as synthesizers,
drum machines, CD players, tape decks, or effects processors) to any of the
SD8’s eight channels using this electronically balanced 1/4" jack (balanced or
unbalanced signals can be accepted here). WARNING: Do not connect a
channel’s line input if you already have something connected to its microphone
input; each channel is designed to accept only one source or the other.
9: Mic input connector - Connect a microphone to any of the SD8’s eight
channels using this standard XLR jack. This jack is intended to accept signal
from low-level, low-impedance mics but can also be used to accept signal from
other sources (such as direct injection boxes) if the input Trim control is turned
down (see #4 on the previous page). WARNING: Do not turn the SD8’s
Phantom power on if signal sources other than condenser microphones (or
active direct injection boxes requiring 48 volts of power) are connected to any of
these inputs (for more information, see #3 on page 9). Also, do not connect a
channel’s microphone input if you already have something connected to its line
input; each channel is designed to accept only one source or the other.
