Samson 112C 用户手册

8.  Adjust the Bass, Treble and Graphic Equalizer 

controls to taste. (When you get a great setting that 

complement's your instrument and playing style, it’s 

a good idea to write it down for future use.)
9. Press in the Shape switch and turn the Shape 

knob both clockwise and counterclockwise to hear 

the effect of the Shape curve and filter on the sound 

of your bass. Leave the Shape knob at the point 

where it best complements your particular instru-

ment and playing style. For more on SHAPE see the 

section Using the Shape Circuit on page 12.
10.  Now try out the Hydrive combo’s Compression 

circuitry.  Activate it by turning the Compression 

knob clockwise from its “Zero” position.  As you turn 

the knob clockwise, the input signal from your bass 

becomes more and more severely compressed—

you’ll hear peak signals (such as string slaps and 

pulls) begin to sound increasingly “squashed,” rela-

tive to the lower-level signals produced by standard 

playing.  The result will be a decreased dynamic 

range but an overall leveling of signal throughout 

the full pitch range of your instrument.  In the 112C, 

115C and 210C, the Compression LED will be off 

when no compression is being applied, will go on 

whenever small amounts of compression are being 

applied and will flash or light steadily blue when 

limiting (severe compression) is being applied. 
11.  If you’re using a professional external signal 

processor that has Line-level inputs and outputs, 

turn your Hydrive Combo amp off momentarily 

and then connect a standard audio cable between 

the rear panel Preamp Out jack and your effects 

processor input and another standard audio cable 

between your effects processor output and the Amp 

In jack. (If required, multiple effects processors can 

be daisy-chained together, output to input).  Then 

turn the Hydrive Combos amp back on and play 

your bass while adjusting the controls of your effects 

processor(s).  For best results, set both the input and 

output gain of the connected effects processor(s) 

to 0 dB (unity gain), so that there is no increase or 

decrease in level whether the effects are switched in 

or out.
