Introduction
Thank you for purchasing the Korg TPB-2 Dual Tube Preamp Board w/
Optical Compression. In order to enjoy long and trouble-free use, please
read this owner’s manual carefully and use your TPB-2 only as directed.
Features
The TPB-2 is a dual-channel preamp featuring two 12AX7 vacuum
tubes, plus fast operating and transparent optical compression and
limiting circuitry. Designed to accept a variety of sources over a wide
range of levels, it is ideal for your most critical and demanding recording applications.
Using a specially tuned version of our acclaimed Valve Force circuit, the
TPB-2 delivers the robust, musical warmth and mid-low region presence
typical of vacuum tubes. The optical compression responds quickly and
transparently, providing a distinctly full analog body without adversely
coloring the sound. In addition, the optical compressor’s gain reduction
and limiting circuitry allow you to avoid any audio clipping while
you’re recording.
5. Insert the TPB-2's flat cable into the connector.
Make sure that the connector is oriented correctly, and press it firmly
in until the connector lock engages.

Installing the TPB-2
Before you install the TPB-2, make sure that your D32XD/D16XD’s
operating system is version of 2.0 or higher. The system version is
displayed in the LCD screen when you turn on the power (see the
illustration in step 8).
For details on how to update the system, refer to page 95 “Updating the
system” in the D32XD/D16XD owner’s manual.
1. You will need a Phillips (+) screwdriver.
2. Turn off the power of the D32XD/D16XD, and disconnect all
cables.
The interior of the D32XD/D16XD reaches high temperatures during
operation. Before you perform this operation, turn off the power and
wait at least 30 minutes for the interior to cool down.
3. Use the screwdriver to remove the four screws that fasten
the AIB-8 cover (or AIB-8).
Be careful not to lose these screws; you will need them to install the
TPB-2.

or AIB-8
4. Remove the AIB-8 cover (or AIB-8).
If the AIB-8 is installed, release the flat cable of the AIB-8 from the
connector lock by squeezing in on the tabs on the side of the cable
(see the illustration below), and remove it.
The flat cable and the AIB-8 will be damaged if you forcibly pull the cable
without releasing the lock.
6. Install the AIB-8 in the D32XD/D16XD.
First, insert the front edge (the edge where the cable is located) into
the opening that had been covered by the AIB-8 cover (or AIB-8), so
that the flat cable is folded inside the D32XD/D16XD. Next, lower
the back edge into place.
7. Fasten the AIB-8 in place, using the four screws that you
removed and remembered not to lose in step 3.
8. When you are finished, turn on the power and verify that
the TPB-2 is installed correctly.
If it is installed correctly, the TPB-2 icon will appear in the LCD
screen when you turn on the power.
If this icon is not displayed, it may be that the TPB-2 was not
installed correctly. Immediately turn off the power, and verify that it
was installed correctly.
Even if the TPB-2 is installed correctly, the TPB-2 icon will not appear if
the D32XD/D16XD system version is not 2.0 or higher.
