PARAMETER
IN 1 (INSTR) INPUT PAD
(0 db, 6dB, 12dB, 18dB)
OUT 1 (MAIN) NOMINAL LEVEL
(+4 dBu, -10 dBv)
IN 2 (FX RTN) NOMINAL LEVEL
(+4 dBu, -10 dBv)
OUT 2 (FX SEND) BOOST/PAD
(0, 12 dB)
Description
Pads the signal from IN 1 [INSTRUMENT] before it reaches the A/D
converter. The pad is offset by a corresponding but opposite boost at
the output of the converter, so "what you hear" remains the same at all
settings.
Run this at the lowest possible setting for your guitar, increasing padding
only when required.
Sets the nominal level of Output 1.
+4 dBu is the default. It is designed for use with professional audio
equipment. It is unlikely you will ever need to change this setting.
Use the -10 dBV setting for consumer-grade or other equipment.
The product manual for your connected equipment should indicate
whether it operates at +4 dBu or -10 dBV. (Some devices are switchable.)
Sets the nominal level for Input 2.
+4 dBu is the default. It is designed for use with professional audio
equipment.
Use the -10 dBV setting if Input 2 is fed by the outputs of consumer-
grade or other equipment operating at this level.
The product manual for your connected equipment should indicate
whether it operates at +4 dBu or -10 dBV. (Some devices are switchable.)
Engages a boost/pad to lower the noise floor of Out 2.
This is useful if the device in your FX Loop is a tube amp or an amp
modeler. Be careful with this setting, however, as you will be driving the
AX8's FX SEND D/A converter at +12 dB, making it easier to clip. Watch
the front panel FX SEND CLIP indicator and if clipping occurs, reduce
levels within your preset or turn this setting back to the default of 0 dB.
