What is a Reamp?
A line level to instrument level interface.

The history of Reamps.
The Term "reamp" was copyrighted in 1994 by John Cuniberti but studios had been Reamping for quite some time before the concept became a profitable endeavor. Jeff Harris recalls using a similar device in the early seventies while working on a Steely Dan record.

Overview of the Reamp's circuitry.
The signal comes in through an XLR connector and immediately hits several resistors, a PAD, and a Transformer before reaching an instrument level output.

What's the difference between this and a DI Box?
A DI takes an unbalanced, low impedance, instrument level signal and turns it into a balanced, high impedance mic level signal. A Reamp takes a line level, high impedance balanced signal and turns it into an instrument level, low impedance unbalanced signal.

Building begins - 8:30pm

Begin by applying solder preemptively to all of the XLR pins.

Second, take the twisted black and red wires. Cut off a piece just long enough to bridge the two XLR connectors and strip the ends. Tin the exposed wire and solder.

In series, add the resistors, PAD, and transformer to the gridded circuit board connecting out to the instrument cable output. From the ground wire, add the ground lift switch.

Testing the finished build
Students tested their finished build by running a prerecorded signal back through an amplifier. All students were able to successfully route signal into and out of their build.

End Time: 10:30PM
