Technical Tests of Ensoniq PCI Sound Card
-by Arny Krueger
Analog I/O tests of the Ensoniq PCI sound card show fine performance. Remember that the distortion and frequency response shown is for a round trip through the card - using both the ADC and DAC components of the card. They are therefore show about twice what one would see using this card as either a ADC or DAC. Round-trip frequency response is smooth, and within +/- 0.2 dB up to 17.5 kHz. Two-way THD at 1 kHz is 0.0051 %, and S/N is 74 dB. Only the S/N is substantially poorer than the TB Fiji to a degree that could be possibly audible with music. Of course, this card also lacks digital I/O. This is all quite good performance, particularly considering the price. Installation experience with this card has been good - it follows general Win95 plug-and-play specs. If you have formerly installed a SoundBlaster Pro or SB16 in the system, you may want to run the provided SETUP program to get the DOS driver installed, or you may get Windows Protection Error on boot. If you are running Windows-only multimedia programs, you can disable the "Legacy" driver and reclaim an IRQ. It is feasible to run several of these concurrently to obtain more than 2 channels of full duplex sound. For more hints on using the Ensoniq Audio PCI take a look at the "unofficial" Audio PCI website at: http://204.186.128.102/ Ensoniq software updates are in the "downloads" section of the Ensoniq website or by FTP from: ftp://ensoniq.inter.net/pub/ensoniq/
