SoundBlaster 32 PNP (1994) CT3600


often mistaken for an AWE32 The Sound Blaster 32 (SB32) was a value-oriented offering from Creative, announced on June 6, 1995, designed to fit below the AWE32 Value in the lineup. The SB32 lacked onboard RAM, the Wave Blaster header, and the CSP socket. The boards also used ViBRA integrated audio chips, which lacked adjustments for bass, treble, and gain

lets start out by saying loud + clear, there are many different model #s of sound blaster cards..
and many different models of awe32 cards within those sound blaster cards.
the important thing to know is whether or not your card is pnp (plug&play)
if its a pnp card then all of the important resource configurations are done via software
if its not a pnp card then all of the config is done by adjusting hardware jumpers or dipswitches on the actual card itself
having the correct set of drivers for your card is crucial.. especially if u are using a pnp card.
plugnplay was a very new concept around the time of the awe32 (1994)

this patch will allow you to have more options of which IRQ to use for the card its a patch from late 1996

install with this cd:

use whatever patches u need from here:


info regarding different model sound blaster cards

drivers (dont use these use the full 190mb cd linked above this is missing the pnp manager CTCM/CTCU that comes with the cd which is needed to properly set irq/base address on the card without this utility u are stuck with whatever the card is already set to dont make the same mistake i did!!!)

The Sound Blaster 32 is a standard Sound Blaster16 with the EMU 8000 Advanced WavEffect music synthesizer chip. The card includes all the standard Sound Blaster16 features.

The EMU8000 is a sub-system offering high quality music synthesis using advanced wave effects technology. It comes with an onboard dedicated effect engine. The effect engine provides high quality effects like reverb and chorus to MIDI playback. The EMU8000 supports up to 32 voices, and the effect amount for each voice can be controlled via MIDI.

The main difference between the AWE32 and Sound Blaster32 cards is the onboard memory, 512k memory on the AWE32 cards vs. 0 k on the Sound Blaster32 cards. In addition, there is a Wave Blaster Header on the AWE32 cards, not in Sound Blaster32 cards.

One topic I keep banging on about is the advantage of having digital outputs (like S/PDIF -- and if you're wondering just what S/PDIF is, check out the sidebox explaining all about it) on your PC sound system, allowing you to transfer your digital audio to a DAT machine entirely in the digital domain. Observant owners of the Creative Labs AWE32 card may have noticed that the manual states that the card does have an S/PDIF output, which makes it look like a very cost-effective way to add this facility to your PC, as all you have to do is make a simple lead.

Unfortunately, it isn't as useful as it first appears. In fact, only the signal from the onboard Emu 8000 synth chip is connected to this output, so you will only get the output of the AWE's synth section (ie. the MIDI sounds) from this connector -- no wave files or CD audio. To look at it in a more positive light, you do get a very high-quality sample playback system, which is easily on a par with many semi-professional quality musical instruments, as it is not 'filtered' by the AWE's consumer quality audio electronics.

Creative Labs have produced an application note that tells you how to connect up the S/PDIF signal. This is available on the web from:


For anyone who doesn't have access to the Internet, here's a quick resumé of the process. First remove the AWE from your PC and lay it on a flat surface, with the component side up and the metal mounting bracket on the left-hand side. The S/PDIF pins are located on the component side of the AWE, about a third of the way along the PCB from the left-hand end -- ie. away from the metal mounting bracket. The connector is labelled J10 and S/PDIF. The two pins of J10 are labelled 0 and 1; 0 is the signal and 1 is the ground. The easiest (and safest) way to connect a digital device to the card is to mount an RCA (phono) socket on a blank back plate and make a cable with a 0.1-inch header connector to attach the RCA socket to the AWE32's S/PDIF pins. Maplin part number HB59P looks like it might be suitable for attaching to the connector on the PCB. Creative Labs do apparently sell a kit with the appropriate parts, but I have been unable to find out how you can purchase it -- you could try ringing their salespeople on 01734 828291 for more information.

By fitting an RCA phono connector to bring the digital signal out of your PC, you can use a standard mono phono cable to connect your PC to the digital device, and can then disconnect your DAT or DCC without having to open up your PC. This method of connection is also more robust than a flying lead, and will prevent the cable from accidentally coming adrift from the AWE32. When using the S/PDIF output, the AWE's analogue outputs and mixer will continue to operate as normal. However, changing either the MIDI or the master volume levels with the mixer will not have any effect on the level of the digital output.

Creative Labs say that with a reasonable quality audio amplifier and speakers, you will hear an enhanced sharpness and clarity of the music, together with an almost total lack of noise and hiss. The dynamic range of the system will also increase significantly.

Here is a 10-stage checklist for the whole procedure:

1. Assemble the backplane to AWE32 S/PDIF cable assembly (if working from kit).

2. Open the system unit of your PC (see manufacturers instructions).

3. Locate AWE32 and remove.

4. Locate the S/PDIF connector pins.

5. Attach adapter cable to pins (red side to 0).

6. Re-fit AWE32 to system, taking care to ensure that all cables are securely connected.

7. Fit adapter to backplane slot adjacent to AWE32.

8. Close system unit.

9. Connect adapter to DAT, DCC or amplifier.

10. Test the digital output by playing a MIDI file using the AWE32's synthesizer.
