CSP-4.8
4. OUTPUT SELECT
There are eight outputs on the CSP-4.8 and each
output can obtain its source from any input or
combination of inputs. Select an output channel
to edit its Source, Gain, Polarity, EQ, Delay,
Crossover, or Limiter functions.
5. LED INDICATORS
Each input and output has a five segment LED array for audio level display, ranging from -20 through
clipping. The -20 LED is two-color, also serving as the Mute indicator by turning red. The meter scale is
factory set so that 0 on the meter is 0dBu (0.775Vrms), however it can be easily changed to VU scale (0 =
+4dBu, or 1.228Vrms) within the Util menu.
6. AUDIO FUNCTIONS
1) Gain
Input and Output Gain are separately adjustable
from -40dB to +12dB in 0.1dB increments. The
output gain menu also provides for selection of
input source(s) for a given output channel, as well
as polarity of the outgoing signal. Any input or
combination of inputs can be routed to any or all
outputs. Keep in mind that two signals which
share significant content, such as a stereo source,
will be up to 6dB louder when combined.
2) EQ
- The CSP-4.8 EQ section offers full parametric EQ as
well as 1st and 2nd order shelving filters on inputs
and outputs. Each input channel has six selectable
EQ filters, while each output channel has four
selectable EQ filters. In all cases, each filter is
selectable between parametric (PEQ), 1st order Low
Shelf (LS1), 2nd order Low Shelf (LS2), 1st order
High Shelf (HS1), and 2nd order High Shelf (HS2).
- Shelving EQ filters : 1st order filters use a gentle
6dB per octave slope, while 2nd order filters use
a 12dB per octave slope for more a pronounced
boost or cut. All shelving filters have a boost/cut
range of +/-15dB. Low shelving filters have a
frequency range from 19.7Hz through 2kHz, and
the high shelving filters range from 3.886kHz
through 21.9kHz. Shelving filters are most useful
as broad tone controls to boost or cut the high
end or low end of an audio signal's frequency
content. Because they affect a wider spectrum of
audio, they are not as suitable for feedback control as parametric filters.
