Product Information

addition if realistic sound synthesis is important. However with the daughterboard installed, you can't use the adjacent slot). CT2771 is an odd card with no information anywhere on the web - let me know if you have any details of this card. Other Creative cards often used the '1' suffix to indicate it was a "value" version of the "0"-suffixed card, so this is perhaps a "value" on top of a "value" card ;-) Either that, or it's some OEM variant.

The majority of Sound Blaster 16 cards feature either a discreteYamaha YMF262OPL-3 FM synthesizer as used on the Sound Blaster Pro II, or a Creative CT1747 chip which has this synthesizer integrated. Some post-1995 cards (notably the CT2910) feature the fully compatibleYamaha YMF289FM synthesis chip instead. All of these contain true Yamaha OPL-3 circuitry.

Third Generation (CT29xx)

Several versions of the CT2501 ViBRA-16 chip exist, including CT2501-TBQ, CT2501-TCQ and CT2501-TDQ. The CT2740 was a "Value Edition" card. It pre-dates the "earliest" 2nd-gen SB16, the CT2230. Note the CT1747 chip did not yet have the "OPL" licence logo on it - this is most likely because Creative had not received permission to put it on there from Yamaha at the time this board was made. The Sound Blaster 16 ASP has a 20-voice Yamaha YMF-262 chip for MIDI that produces a relatively disappointing range of sounds. (An optional daughterboard with a 32-voice E-MU chip would be a worthwhile Marc Sven Schulte informed me of the fact the DAC chip on these cards is sometimes the AK4501-VS by Asahi Kasei Microelectronics (AKM) and not the Creative-branded CT1701-T. It's possible Creative simply took this third-party DAC and got permission to rebrand it.

The CT1770, actual name Sound Blaster 16 SCSI-2, was the first Sound Blaster 16 card from Creative Labs to come with a SCSI-2 CD-ROM interface instead of IDE or other proprietary interfaces from Panasonic, Mitsumi and Sony. To support this SCSI interface, the card has an Adaptec AIC-6360L controller chip - you need to install an ASPI driver for this chipset from your CONFIG.SYS file followed by the usual MSCDEX in your AUTOEXEC.BAT. Creative Labs introduced the 2nd generation of Sound Blaster 16 cards in 1994, starting with the CT2230. The key difference from the 1st generation is that the Yamaha YMF262 was now gone as a discrete chip. Instead Creative Labs integrated the YMF262 into their own chip called "CT1747". These chips got the official "OPL" logo stamped on them, as they did contain the Yamaha circuitry inside. Also sadly gone was the hardware thumbwheel volume control.The CT2230, full name Sound Blaster 16 MCD ASP (Multi-CD with ASP chip) was the first of the 2nd-generation Sound Blaster 16 cards. Like the 1st-gen CT1750 it got The CT2770, full name, Sound Blaster 16 Value, was launched in 1994. Being a value edition card, it was pared down to the minimum - no wavetable header and only a Panasonic CD-ROM interface.

The CT2230 and CT2290 seem to be the most loved SB16s because they offer the lowest noise output of all the SB16 cards and are not Plug & Play. This is good because we retro gamers like to have our choices at the hardware level! Plug & Play was in its infancy in 1994, and would make configuring your card almost impossible outside of Windows. Open your computer and locate the CD-ROM and each of the cables connected to it. Below is an example of a disc drive, including where each of the cables should connect to the drive. The least noisy of the Sound Blaster 16 second-gen cards are the CT2940 and CT2980 with an embedded Yamaha YMF chip. These have the CT2502 (ViBRA) chips and are Plug & Play. CT2230 / CT2239 The CT2260 was an OEM version of the CT2230, though with some major differences. The CT2330's integrated CT1747 (FM synth chip) was replaced with Creative's new ViBRA-16 chip - CT2501. This was Creative's answer for the OEM market for Sound Blaster 16 - a cheap and cheerful solution that integrated the bus controller interface, DSP, mixer and codec into a single chip. This same chip would go on to be used on the Sound Blaster 32 range and many more budget ("Value edition") cards. The Sound Blaster 16 ASP comes with a powerful mix of applications, including two programs for sampling in Windows. WaveStudio is limited to sampling and editing what will fit in system memory (about a minute of 44 kHz sampling). If that's enough, you'll enjoy its intuitive interface and strong editing capabilities. Soundo'LE is the appropriate application for creating longer samples and embedding them into OLE-aware applications. The Sound Blaster 16 mixer, which you can access from Soundo'LE's menus, is very powerful and easy to use."InfoWorld, 11 Jan 1993With its timeless design and clean lines, the CD Jumper exudes elegance and versatility. It can be easily dressed up or down, making it suitable for various occasions and outfit combinations. Fun fact... user Imperious on the Vogons forum says he successfully ran a CT2770 on an 8088 XT (8-bit ISA slots only). The 16-bit part of the card is used for the CD-ROM interface only! Imperious said it's great for running the PC speaker audio through the sound card and out of the speakers, though there's only a tiny amount of games that can use the card's abilities on a system that slow. The CT1745A mixer chip from 1992 got an upgrade during this 2nd generation to CT1745-S (1993) and later to CT1745A-S (1994), though the first CT2230 cards still came with the original CT1745A.
