INPUT GAIN
The input gain control is to accommodate a variety of instrument outputs. In
the 12:00 position, the input gain is where you want it for most magnetic pickup
systems. For higher output pickups, active pickups, mics or effect devices, you
can adjust the input gain down so the preamp is not overloaded. For lower output
devices such as piezoelectric transducers, you can adjust the input gain up. The
input gain control setting should be experimented with in concert with the volume
control setting on your instrument and each instrument will be different so start
with the control at 12:00 and go from there.
INPUT JACK
The JazzAmp has a 1⁄4”/XLR combo INPUT jack on each channel. This jack may
be used to plug in a standard 1⁄4” instrument cable or an XLR cable. The XLR
is unswitched 48-volt phantom powered, so refer to the device manufacturer to
confirm compatibility.
