Anleitung Zusammenfassung
It is on when the switch is pushed in. Turn this switch on when connecting a high output impedance device such as guitar or bass. 5. PAD switch This switch lowers the level of the input signal by 26 dB. The pad is on when the switch is pushed in. When a line level input source is connected, turning the pad on will allow the gain trim knob to have a wider useful range of adjustment. 6. Compressor mode switch This switch changes the compressor’s response speed. Use the Fast setting for short sounds such as drums or percussion, and the Slow setting (press the switch in) for more sustained sounds, such as vocals. 7. Low cut switch This switch activates a 70 Hz –6 dB/oct low cut filter. Use this to reduce unwanted low-frequency content. The filter is on when the switch is pressed in. 8. Level meter The meter shows the audio level. If the needle moves into the red area above 0 dB, this indicates that digital clipping is occurring. Set the gain trim knob and the compressor sensitivity knob to prevent the needle from exceeding 0 dB. 9. Gain reduction LED This LED will light when gain reduction is being applied by the compressor. 10. Compressor sensitivity knob This specifies the audio level where the compressor begins to kick in. Turning the knob toward the right will increase the sensitivity, so that compression will be applied even at low levels. If you don’t want to apply compression, turn this knob all the way to the left. 11. Link switch Press this switch in to link the two channels together for use with stereo sources. When linked, compression will be applied equally to both channels whenever either channel exceeds the compressor’s sensitivity threshold, preserving the stereo imaging. 2. Operation 2-1. Assigning the input The inputs of the TPB-2 will show up as Input 9 and Input 10 on your D32XD/D16XD. The audio sources connected to the TPB-2’s inputs can be assigned to any of the mixer channels. (See D32XD/D16XD owner’s manual, p.42 “1. Inputting audio to the mixer”) Preamp input INPUT 9 is shown as the icon, and INPUT10 is shown as the icon. •Access the MIXER, INPUT/OUTPUT/CH ASSIGN, “Ch Assign” tab page. •Select “SOURCE” for the channel you want to assign, and use the buttons to select . You can also use the value dial or the +/– keys to make this selection. In the same way, select for another channel. 2-2. Adjusting the input level When you’ve finished making your connections, watch the TPB-2’s level meter while you use the gain trim knob to adjust the level. Set the trim knob so that the level meter needle does not exceed 0 dB when the loudest sound is input. If the level meter goes beyond 0 dB even when the gain trim knob is turned all the way toward the left, press the PAD switch and then use the gain trim knob to adjust the level. Normally if the needle goes beyond 0 dB, digital clipping has occurred, causing distortion. You should set the level so that it does not exceed 0 dB. 2-3. Using the compressor urn the compressor sensitivity knob all the way to the left so that the compressor is not being applied. Use the gain trim knob to raise the level so that the meter slightly exceeds 0 dB during the loudest input passages. Slowly turn the compressor sensitivity knob toward the right. The gain reduction LED will begin to light, indicating that the compressor is being applied. While watching the level meter, continue turning the compressor sensitivity knob until the level does not exceed 0 dB during the loudest input passages. If you want to apply a lot of compression to intentionally “squash” a vocal, use the gain trim knob to raise the input level further, and turn the compressor sensitivity knob toward the right to increase the compression. By using the gain trim knob to raise the preamp level appropriately, you can saturate the vacuum tube, generating analog overtones to enrich the sound in conjunction with the compressor. 2-4. Using the link switch Turn on the link switch if you want to use stereo compression. When you’re recording a stereo source, and the level of one channel rises to the point where compression is being applied to only that one channel, then the relative volume of the other channel will increase, producing the impression that the stereo image has shifted to one side. In such cases, turning on the link switch will automatically apply compression to both channels at the same time, whenever either channel reaches the compressor’s threshold level. So that the compressors for both channels will function in the same way, select the same compressor mode setting for both channels (either Fast or Slow). You should also set the compressor sensitivity knob to about the same setting for both channels. 3. A note about the vacuum tubes This device contains vacuum tubes. We recommend that you allow the tubes to warm up for about ten minutes after you turn on the power, before you begin running any audio signals through the TPB-2. If you begin using this device immediately after turning on the pow...
