JUMPERS

Product Information

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. The CT2260 appeared to be pretty good compatibility-wise, working well for every game I tried. It has a wavetable connector which I tried and it worked well with my NEC XR385 daughterboard, however I can confirm the presence of the "hanging note" bug with this card. Board revision 29417 got either the old CT1745A mixer chip from the first generation, or the newer CT1745-S. Board revision 49432 got the even later CT1745A-S. Whether you're heading to the office, meeting friends for a casual outing, or enjoying a cozy evening at home, the CD Jumper is a stylish choice. Pair it with jeans for a relaxed yet chic look or dress it up with tailored pants for a more polished ensemble. The CT1780 was the same as the CT1750 with the exception that the CD-ROM interface was for LMSI (Laser Magnetic Storage International) drives. LMSI was a subsidiary of Philips. The interface itself is a 16-pin header. The only other sound cards that came with an LMSI connector were the MediaVision Pro Audio Spectrum 16 LMSI (FCC ID: ICW-PAS16P) and MediaVision Fusion CD16 S/E LMSI.

addition if realistic sound synthesis is important. However with the daughterboard installed, you can't use the adjacent slot). The CT1703-TBS is apparently decent for noise (low) and is also found on the CT2290, AWE32 and AWE64. In June 1992, the Sound Blaster 16 was introduced as the successor to the Sound Blaster Pro, though the Pro was sold for a number of years alongside the SB16. The first '16' model was CT1740. For the first time you could get a Sound Blaster card with CD-quality (44 kHz) digital audio sampling.

Before getting started

Despite the model number, the CT2700 is still a 1st-generation card, being almost identical to the CT1740 and CT1750 cards, except that it gets only a Mitsumi CD-ROM interface. More Images CT2772 was the same as the CT2770A, but got FCC ID: IBACT-SB16NCDR, which I can only assume means "No CD-ROM", as it didn't come with a CD-ROM interface, but this card did come with a wavetable header which is odd for a value edition card...

The design of the Sound Blaster 16 board, which varied from model to model, could further exacerbate CQM's inaccuracies. Despite its shortcomings, it was much more faithful-sounding than the sample-synthesis simulation that AudioPCI-based sound cards employ. Boards utilizing CQM synthesis have a CT1978 chip, or they may have CQM integrated into another chip, e.g. ViBRA16C/X-based boards. The CT1790, also called Sound Blaster 16 Sony is the same as the CT1740 but with a Sony CD-ROM interface. More ImagesSound Blaster 16 Value edition. Most of these have the CT1978 CQM FM synthesizer chip which is almost universally considered poorer quality than a true Yamaha OPL3 chip (some CT2980 cards have the original Yamaha chip which is preferable). If it has the Yamaha chip instead, this is one of the lowest-noise SB16 cards you will find.

Following the success of the CT2260 and its first ViBRA-16 card, the CT2800 or Sound Blaster Vibra 16S, uses an updated chip - the ViBRA 16S (CT2504). 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 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 1993 CT2770A then followed, removing these obsolete CD-ROM interface headers from the board as well as the CSP/ASP chip area.

First Generation (CT1xxx)

offers the same high quality sound, plus the facility to upgrade. Also available with advanced signal processing for enhanced sound capability, it features both IDE and Creative/Panasonic CD Rom interface."

CT2830 is similar to the CT2700 and even the original CT1740 Sound Blaster 16, in that it has a real Yamaha OPL3 chip, has the same DSP and even still supports a CSP/ASP chip. It comes with an IDE 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. Board revision 29409 was the original CT2770 and still had the other CD-ROM interface solder pads for Mitsumi and Sony drives, plus the CSP/ASP chip solder pads.The CT2919 was the non-"Value Edition" version of this card, designed for the OEM market. More Images The CT2291 is the "Value Edition" version of the CT2290. These do not support having a CSP/ASP chip. These cards also only have an IDE connector - no 'Creative/Panasonic Drive' connector. With 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. This card has been reported to have the hanging note bug, but the only cards I have seen have DSP v4.16 which does not suffer this. More Images 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.
