USING TCDP The TCDP program lets you play music from standard audio compact discs at the MS-DOS command prompt. You can run other programs from the hard drive or diskette drive while a CD plays. To use TCDP, change to the hard drive and type tcdp and press ENTER. The TCDP control panel is displayed. Use the mouse or the arrow keys to highlight the symbol that corresponds to the action you want to perform. The symbols on the control panel are similar to those on a CD player or tape player. When you select a symbol, its description is displayed in the lower right corner of the control panel. To activate the highlighted option press ENTER, press the space bar, or click the mouse button. The counter displays the time elapsed for a track. You can also enter TCDP command options at the MS-DOS prompt. To review the commands available, type tcdp ? and press ENTER. After you decide which options to use, type tcdp /o and press ENTER. Where o is one or more of the options you want to user. Like SBP-MIX, SBP-SET lets you adjust the volume of audio sources, mix sound, and choose filters. The SBP-SET command line in the AUTOEXEC.BAT file runs SBP-SET automatically at system startup. Volume adjustments made by changing the SBP-SET command line in AUTOEXEC.BAT are recognized after a system restart. SBP-SET lets you perform the following tasks: -Select an audio source for recording -Choose a filter. -Adjust the volume for an audio source. -Adjust the master volume. -Mix sound from different audio sources. You can also run SBP-SET from the MS-DOS prompt. Exit Windows. At the MS-DOS prompt, type SBP-SET/H and press ENTER. A description of each SBP-SET command line option is displayed. Run the program again using the options of your choice to adjust volume. The default SBP-SET command line is: SBP-SET / M:10,10 /VOC:10,10 /CD:10 /FM:12,12 /LINE:10,10 M sets the master volume left and right channels, VOC sets the left and right channel of voice, CD sets the volume for a CD, FM sets synthesizer volume, and LINE sets the volume for a line audio source. To change the volume level for sources used with MS-DOS based applications, use an editor to change the SBP-SET lien of the AUTOEXEC.BAT file in your root directory. USING SBP-MIX SBP-MIX is a terminate-and-stay-resident program that lets you adjust the volume of audio sources. The program remains in memory until you remove it. Exit Windows. At the MS-DOS prompt, type SBP-MIX and press ENTER. After installing SBP-MIX, you can activate it by pressing the ALT+1 hotkey. (Press and hold ALT, and then press 1). The SBP-MIX window is displayed. Use the arrow s=keys to select audio sources and adjust volume levels as described below: -MASTER VOLUME - Adjusts the volume of digitized sound. -VOC VOLUME - Adjusts the volume of digitized sound. -LINE VOLUME - Adjusts the volume of the line-in audio. -CD VOLUME - Adjusts the volume of CD-ROM drive output. -MIC VOLUME - Adjusts the volume of a microphone. -FM VOLUME - Adjusts the volume of synthesized music. After selecting an audio source, press ENTER. You can also select the ADC test option and set it to ON to test ADC input. Select the ADC channel option to choose MIC, CD or LINE ADC input and set the filter to HIGH or LOW. Select the FM Channel options to set FM steering. All settings remain in effect as you use audio features with MS-DOS applications. When you run Windows or restart your computer, the SBP-MIX volume settings are cleared. To remove SBP-MIX from memory, type SBP-MIX/U and press ENTER. After removing SBP-MIX from memory, you can change the hotkey combination. To change the hotkey combination, enter a command in the following format at the MS-DOS prompt: SBP-MIX/k hotkey Where hotkey is the key combination you want to use as the new SBP-MIX hotkey. The hotkey must include two keys: -A shift status key (SHIFTL, SHIFTR, ALT, or CTRL) -Any number (0-9) key on the main keyboard For example, to change the hotkey to CTRL+6, type SBP-MIX/kctrl6 and press ENTER.
