Instrument Inputs (Channels 1 and 2).
The ¼” TS connector on channels 1 and 2 are for use with an
instrument (guitar, bass, etc.). When an instrument is plugged into the instrument input, the
microphone preamplifier is bypassed and the FP10 becomes an active instrument preamplifier.
NOTE: Active instruments are those that have an internal preamp or a line level output. Active
instruments should be plugged into a line input rather than into an instrument input. Plugging a line
level source into the instrument inputs on the front of the FP10 not only risks damage to these inputs
but also results in a very loud and often distorted audio signal.
(In other words, don’t plug a line level source into the combo jacks of channels 1 or 2.)
•
Input Gain/Trim Control.
This knob provides the following gain structure:
o
XLR Microphone Inputs.
45dB of variable gain (+14 dB to +55dB)
o
TS ¼” Instrument/Hi-Z Inputs.
45 dB of variable gain (+8dB to +50dB)
o
TRS ¼” Line Inputs.
-10dB to +10dB trim adjustment
•
Clip Indicator.
The clip indicator will light up if your input signal from the XLR (Mic) or ¼” (line)
r18dBu (0dBfs). At this level, your mic preamp/line trim signal may not exhibit signs of
clipping such as distortion. However, this level will cause the ADC (analog to digital converter) to clip.
Therefore it is highly recommended you do not allow your converters to clip (the clip indicators to light
up) as the sound quality would not be desirable.
