This article covers Creative Labs CT4750 サウンドブラスター PCI 128 サウンドカード.

Overview

The Creative Labs CT4750 Sound Blaster PCI 128 is a classic sound card that defined PC audio for many enthusiasts in the late 1990s and early 2000s. It connects via the PCI bus and delivers 4.1-channel surround sound, offering a significant step up from the tinny onboard audio of that era. Its key strengths include the legendary Sound Blaster compatibility with DOS and Windows games, plus 128-voice wavetable synthesis for cleaner instrument playback. Today, this card is primarily sought after by retro PC builders and classic game collectors who want authentic audio performance on period-correct hardware.

Connectivity & Compatibility

Interface: PCI (32-bit, 5V key). Not compatible with PCI Express slots in any form. Audio output: 4.1-channel analog surround (front L/R, rear L/R, subwoofer) via 3.5mm jacks. Supported OS: Windows 9x/Me/2000/XP. No official drivers for Vista or later. Compatible devices: Desktop PCs with a free PCI slot. Laptop compatibility is essentially nonexistent.

Product Info

The CT4750 is part of the Sound Blaster PCI 128 family, launched around 1999. It was positioned as a mid-range option, more affordable than the high-end Sound Blaster Live! series while still offering 4.1ch surround. Today, it is available as a used item on marketplaces like . Pricing varies by condition, and warranty coverage is typically limited or absent. Accessories such as driver CDs or manuals are often missing. Market positioning: strictly entry-to-mid-range retro hardware. It is not suitable for modern gaming PCs, high-resolution audio, or ASIO-based music production.

Best Use Cases

Retro PC builders: If you are assembling a Pentium III or Athlon XP machine, this card provides authentic Sound Blaster audio that onboard chips cannot match. DOS game compatibility is a major plus. Classic game collectors: For Windows 9x/XP era titles like Half-Life, Quake III, or Age of Empires II, the 4.1ch output delivers the surround experience these games were designed for. DOS gaming enthusiasts: The SB16 compatibility mode works with many DOS titles. However, for absolute compatibility with the oldest games, a genuine ISA Sound Blaster 16 is still the gold standard. Not recommended for: Users on Windows 10/11 (no driver support). Anyone without a free PCI slot on their motherboard. Audiophiles needing high-resolution or low-latency ASIO performance.

Things to Consider

First, verify that your motherboard has a free 32-bit PCI slot (5V key). PCI Express slots are electrically and physically incompatible — no adapter exists to bridge this gap. Second, OS compatibility is a major limitation. Windows 98 SE and XP work well with official drivers, but Vista and later versions lack support. Linux may detect the card via ALSA, but functionality is not guaranteed. Finally, since this is a used product, inspect the board for capacitor bulging or corrosion. Check seller ratings and product descriptions carefully before purchasing. ## FAQ
Q: Can I use this card on Windows 10? A: Official drivers are not available, and stable operation is not guaranteed. While generic drivers may provide basic functionality, this is not recommended for reliable use. Q: Does it replace a Sound Blaster 16 for DOS games? A: It offers SB16 compatibility mode and works with many DOS titles. However, for the most demanding legacy games, a true ISA Sound Blaster 16 is a safer choice. Q: What speakers do I need for 4.1ch output? A: You need a 4.1 speaker system (front L/R, rear L/R, subwoofer) or five individual speakers. Standard stereo speakers will work in 2ch mode but won't provide surround effects.
