The Line-Out jack is a one-hole connecting interface on your synthesizer
card. It allows you to connect your card to powered speakers or an external amplifier for
This jack may not be available on your card.
The SPDIF (Sony/Philips Digital Interface Format) connector allows you
to transfer digital audio signals from one digital device to another. In this way, the
fidelity of a transferred digital signal is preserved. You can transfer digital signals
from your synthesizer card to a digitaldevice such as a DAT player through the SPDIF

Memory Module Expansion Slots
The Memory Module Expansion slots allow you to install SIMMs (Single
In-line Memory Modules) on your synthesizer card so that you can have more RAM for your
MIDI instrument samples. You can add up to a maximum of 28 MB of RAM using SIMMs. When you
want to use these SIMMs, you need to change the setting of the DRAM jumper on your card.
We recommend that you use a pair of SIMMs with the same capacity. The SIMM RAM access time
must be 80 nanoseconds or faster.
DRAM Expansion Jumpers
If you have installed SIMMs in your synthesizer card's Memory Module
Expansion slots, you can use the DRAM_EN jumper on your synthesizer card to choose between
the on-board 512KB or installed SIMMs.
The factory default setting of jumper DRAM_EN is to use the on-board 512KB.
Some synthesizer cards may not come with the on-board 512KB. Such cards do not have the
DRAM Expansion jumper.
Motherboard Audio Connectors
These connectors are used to connect your synthesizer card to your
motherboard's audio chips, if present. See Appendix C, "Hardware Information"
for detailed information on these connectors.
