Korg owner manual Introduction, Features, Installing the TPB-2

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 ownerÕs manual carefully and use your TPB-2 only as directed.

Features

The TPB-2is 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 record- ing applications.

Using a specially tuned version of our acclaimed Valve Force circuit, the TPB-2delivers 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 compressorÕs gain reduction and limiting circuitry allow you to avoid any audio clipping while youÕre recording.

Installing the TPB-2

Before you install the TPB-2, make sure that your D32XD/D16XDÕs 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.

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.
