MaXiO System Manual

CH. Limit: The CH. Limit setting allows you to limit the maximum number of channels that are

transferred via the PCI bus. If you select 32Ch, all 32 input and 32 output channels are active at the

same time. If you select 16Ch, only the first 16 input and the first 16 output channels are active, if

you select 8Ch, the first 8 input and the first 8 output channels are active. The lower the setting will

be, the lower the PCI transfer generated by the MaXiO PCI host card will be.

· depending on the system performance of the mainboard (and chipset) you use, you need to lower

this setting from 32Ch to 16Ch or 8Ch. Only fast and modern mainboards (check the system

requirements) allow you to use the 32Ch mode.

· the performance you can achieve with your MaXiO PCI host card based system also depends on

other components in your system beside the mainboard (and chipset). For example, other PCI

devices in your system (like high end network adapters, SCSI controllers, SATA/RAID

controllers, etc.) may affect the performance, especially when you use the 32Ch mode and higher

sample rates.

· as a general rule, it is better to use the 8Ch mode if you do not use more than 8 input and 8

output channels or the 16Ch mode if you do not use more than 16 input and 16 output channels.

· as a second general rule, the sample rate you use also affects the system performance, e.g. using

192kHz requires a faster system than using 48kHz. Another example: using 192kHz at the 8Ch

setting affects the system in the same way as using 48kHz at the 32Ch setting or using 96kHz at

the 16Ch setting.

The default setting is 8Ch. If you connect multiple external units such as EX8000 or a single

MaXiO 032 breakout box to one MaXiO PCI host card, you need to change the CH. Limit setting

before you can use more than 8 input and 8 output channels.
