PCI 4.1-channel sound card

The BONAEVER card plugs into a desktop PCI slot and uses the CMI8738 chip to deliver 120 dB signal-to-noise ratio. It provides full-duplex playback and recording with HRTF 3D spatial positioning and supports DirectSound 3D plus A3D 1.0 interfaces. The board handles 24-bit S/PDIF input and output simultaneously, including optical connections. Windows 98, 2000, XP and NT are supported at signal voltages from 0.5 V to 5 V.

Sustained-load behaviour

During extended sessions the card maintains 44 kHz sampling for stereo recording and playback without dropping to lower rates. Full-duplex operation keeps both capture and playback paths active for music synthesis or voice work. The 120 dB signal-to-noise ratio remains stable, so background hiss does not rise as the system warms up. Driver support for the listed Windows versions keeps the audio pipeline consistent over long periods.

Thermals noise and power

The passive design has no fan, so it adds no audible noise to the chassis. Power is drawn directly from the PCI bus within the 0.5 V to 5 V signalling range, requiring no external connector. Heat output is low enough that standard case airflow handles it without extra cooling. The optical S/PDIF ports avoid electrical ground loops that can introduce hum in analogue setups.

Questions about this item

How loud is the fan noise when the BONAEVER 120dB PCI card runs continuously?

The card has no fan; it draws power from the PCI slot and produces no audible noise during operation.

What must I already have inside my PC for this sound card to function?

A vacant PCI slot and a Windows 98, 2000, XP or NT installation are needed for the plug-and-play driver.

Will the CMI8738 card work beside an older ISA sound card I want to keep?

The card uses a standard PCI interface, so it can coexist with legacy ISA audio hardware in the same system.
