![]() IRQ is usually 5 or 7 (5 was the factory default), and DMA channel was usually 1.įor the other settings necessary for the card to work (IRQ number and DMA channel) these are set using one of the tools the INSTALL program puts onto your hard disk, called DIAGNOSE, which we'll come onto in a bit. ![]() NOTE: Some games expect your Sound Blaster to be at I/O address 220, so unless you have a very good reason to change it, keep it on that address. If closed this uses the default MPU-401 address of 330h, but if open it will use 300h. Right next to these jumpers is another one, MSEL. The choices for the former are set via jumpers IOS0 and IOS1 in the lower-middle of the card, with choices of 220h (closed/closed), 240h (open/closed), 260h (closed/open) or 280h (open/open). The Sound Blaster 16 Value CT2770 is what I would consider "semi Plug & Play" - that is, you set jumpers for the I/O addresses the card will use, both for the digital audio part and the MPU-401 (MIDI) interface part. there's no time to waste! Lets get this thing installed and working. It would be better if it had the CT1703 which was much quieter (electrical noise-wise), but that didn't come out until the following year, 1995.Īnyway, enough of the rambling. According to my research it's not the worst - that honour goes to the CT1701 (no suffix). By the way, this Line Out takes signals from the Voice, MIDI, CD, Line-In, Microphone and PC speaker sources and mixes them together. Only this revision and the earlier revision got a Line Out socket, so I'm happy as it seems I have the best of the three revisions. I believe that also, any cards that have the CT1747 do not suffer from the "hanging note" bug, despite the fact that its DSP chip is version 4.12, which normally means it would have the issue.Īnother positive note is that this card got a later iteration of the Creative mixer chip, CT1745 - this is the 'S' model, which expanded on their earlier mixer chips by providing 32 independent levels of software volume control on both left and right channels for Master, Voice, MIDI, CD and Line-In sources. This card came out about a year before Creative began pushing their inferior CQM FM emulation onto cards like this one, so it's good to know this is still a real Yamaha "under the hood". On the plus side, my card here does have a true Yamaha OP元 chip - it's just embedded inside the chip near the middle of the board, CT1747, with the OPL logo printed on it. These all got removed on this one which is 019423. The 029409 board revision of CT2770 still had solder pads for the ill-fated CSP/ASP chip as well as a plethora of CD-ROM interfaces for Mitsumi and Sony too. Despite that, it looks like a nice clean board, almost brand new, and is a good compact size.ĭuring the CT2770s life they produced 3 board revisions: 019423, 029416. As you can see from the main pics above the "Value" label that Creative slapped on this board appears to mean one key thing: the lack of a Wave Blaster header. ![]() Unfortunately, all SB16s have a flawed Sound Blaster Pro emulation mode which means it only plays back in mono, thus causing it to really just be like a basic Sound Blaster when run in this mode.Īll CT2770s got the now useless Creative/Panasonic CD-ROM header (useless unless you have a matching CD-ROM drive!), though it didn't take long for most of us to start daisy-chaining our CD-ROM drives onto the IDE cable from the motherboard anyway, or use the second port, IDE2. SB16 took it one step further with its 16-bit digital audio (CD quality) capability. The Sound Blaster 16 succeeded the Sound Blaster Pro which itself had introduced stereo FM synthesis, but only had 8-bit digital audio. ![]() This meant cost-reducing the SB16 to make a card that was still up-to-date (16-bit) but without the frills. Arriving around two years after the first Sound Blaster 16, and coinciding with the introduction of their new flagship AWE32, Creative were keen to continue selling into the budget end of the sound card market. What was the SB16 Value? Well, there were many cards that got this less-than-spectacular bit of branding, but I will focus on this specific one - the CT2770. This was thrown in as part of a bundle auction where the main 'prize' for me was actually a Slot 1 motherboard, but bundled into the deal were several graphics cards, a Pentium II CPU, some memory, a Sound Blaster AWE32 Value, and this little chap. Welcome to another retro review, today we cover a sound card from Creative Labs - it's my very own Sound Blaster 16 "Value", this particular specimen being model CT2770 in Creative's nomenclature, with board revision 019423.īought as part of a bundle including an ABIT AB-BH6 mobo, AWE64 Value, S3 Trio, and much more in September 2019 for £63 Retro Review: Sound Blaster 16 Value (CT2770) ![]()
