The Creative Labs Vibra 16S CT2504 SoundBlaster 16 audio interface,
supplied on some models in an ISA slot, can be summarized as follows:
• 83 dB SNR
• 8-bit and 16-bit stereo sampling from 5 kHz to 44.1 kHz
• Creative OPL3 synthesizer (11 polyphonic voices)
• connector for WaveBlaster standard (wave-table synthesizer) board
• connector for MIDI /joystick interface (MPU-401 UART compatible)
• microphone input (600 ohms, 30 mV to 200 mV peak-to-peak)
• line-out (stereo) jack can supply 2 W per channel into a 4 ohm load
Drivers are provided on the CD-ROM that is supplied with the PC (5011-
3802) for Windows NT 3.51 and OS/2 Warp. These are required since the
board is Plug-and-Play, but these operating systems are not. The
HP supplied drivers are capable of downloading the required configuration
information for the audio board. The user can select the default
configuration or change any of the parameters. The drivers are not Plug-
and-Play, so they are not able to signal conflicts with other devices. At the
time of release, they bear the version number A.01.02. Windows 95 is a true
Plug-and-Play operating system, and does not need such drivers.
