The SE-120 is a speaker emulator DI load box. It's purpose is to replace a speaker cab and microphone. Instead of
connecting a guitar amp to a speaker cab and using a microphone for recording or live performance you can connect to speaker output
of your amp to the SE-120 and use the Filtered Output of the SE-120.
The SE-120 has an internal reactive dummy speaker load with
3 inputs (4,8 or 16 ohms). It can handle any amp rated at up to 120 watts. This reactive dummy load closely matches
the impedance vs. frequency characteristics of a typical guitar speaker.
The SE-120 has a passive filter that mimics the frequency
response of a close-miced speaker cab (Filtered Output). There is a "Cab" control which sets the low frequency characteristics
(1X12, 2X12 or 4X12) and a "Bright" control which sets the high frequency characteristics (similar effect to the positioning
of a mic on the cone of a speaker).
The Unfiltered Output which can be used to send an unfiltered line or microphone level
signal to a computer for use with software speaker emulation.
The Unfiltered and Filtered Outputs are unbalance 1/4" jacks.
There is also a balanced XLR output that can be switched between the Unfiltered and Filtered outputs.
A Ground Lift switch is
used to float the ground on the XLR output.
The THRU OUT jack can be used if it is desired to use a speaker cab as the load instead
of the internal dummy load.
