DS2416—Owner’s Manual
Introduction
Thank you for purchasing the Yamaha DS2416 Digital Mixing Card. With
8-track simultaneous recording, 16-track simultaneous playback, 24-channel
mixing, 4-band parametric EQ, effects, and dynamics, the DS2416 provides a
complete digital recording studio inside a regular personal computer. Unlike
other audio cards, the DS2416’s five DSPs take the load off the computer’s
main processor leaving it free to concentrate on timing and other tasks while
the DS2416 takes care of high-quality effects, EQ, and dynamics processing.
In some cases, the DS2416’s onboard processing powerhouse may allow audio
software to record and playback a greater number of tracks.
For ease of installation and high data throughput, the DS2416 uses the indus-
try-standard PCI (Peripheral Component Interconnect) bus. Sound cards
such as the Yamaha SW1000XG can be connected digitally, or two DS2416
cards can be digitally cascaded for 48-channel mixing, each providing 2-chan-
nel analog inputs and outputs, with 20-bit 128-times oversampling A/D con-
verters and 20-bit 8-times oversampling D/A converters, and stereo coaxial
digital input and output. Inputs and outputs can be expanded using the
optional AX44 Audio Expansion Unit, which offers four 1/4-inch analog
inputs—two of which can be used with microphones—four 1/4-inch analog
outputs and a stereo headphone jack. Two AX44s can be used with each
DS2416 card for eight analog inputs and outputs.
Yamaha DSP Factory
The DS2416 Digital Mixing Card forms the heart of the Yamaha DSP Factory
system, a range of products designed to bring professional digital multitrack
recording and mixing to personal computers. Other DSP Factory products
include the AX44 Audio Expansion Unit, and several analog and digital
multi-channel input and output options are currently under development.

Introduction
DS2416—Owner’s Manual
System Requirements
• IBM PC compatible PCI bus Windows 95 computer
• DS2416-compatible audio software
System Notes
The DS2416 can be used in any IBM PC-compatible PCI bus personal com-
puter running Windows 95. Since the PCI bus standard relies on the Pentium
processor, computers with earlier processors are not supported. The DS2416
requires a single 5 V PCI expansion bus slot, and cannot be used in 3.3 V PCI
slots. It’s compliant with PCI version 2.1, requires one IRQ (interrupt
request), but no DMA (Direct Memory Access). Since it’s a PCI card, IRQ set-
tings are made automatically. PCI bus speeds other than 33 MHz are not sup-
ported.
Processor type, memory, and hard disk requirements are dependent on the
controlling software, not the DS2416. The supplied device driver requires a
few hundred kilobytes of disk space. Although the DS2416 supports 8-track
simultaneous recording and 16-track simultaneous playback, actual perfor-
mance will depend on the capabilities of your computer and audio software.
Compatible Software
Any software that supports Windows MME (Multimedia Extensions), includ-
ing the Windows 95 Media Player accessory, can be used with the DS2416 for
recording and playback. To use the mixing functions, however, requires soft-
ware that supports the DS2416 mixer. The following software companies are
supporting the DS2416.
• C-Mexx
• Cakewalk
• Canam Computers
• Emagic
• IQS (Innovative Quality Software)
• Musicator
• SEK’D
• Sonic Foundry
• Steinberg

Installing the DS2416
DS2416—Owner’s Manual
Installing the DS2416
The DS2416 installs into a PCI expansion slot and requires no special jumper
settings or interrupt settings.
See your computer’s manual for full details on installing PCI cards.
1
Turn off the computer and disconnect the power cord.
2
Remove the computer’s cover.
3
Choose an empty PCI slot for the DS2416, and remove the screw
from its expansion-slot cover.
To prevent static electricity from damaging the DS2416, touch a grounded
metal part of your computer, such as the power supply case, before handling
it.
4 Carefully align and insert the DS2416 into the PCI slot.
5
Secure the DS2416 using the screw removed previously.
6
Replace the computer’s cover.
7
Turn on your computer.
8
When the New Hardware Found dialog box appears, select “Driver
from disk provided by hardware manufacturer”, and then click OK.
9
When the Install From Disk dialog box appears, insert the driver
floppy disk into the floppy disk drive, and then click OK.
The driver software is installed, and the Windows 95 desktop appears as nor-
mal.
Important: The DS2416 is grounded via the expansion-card fixing screw, so
be sure to tighten it securely.

Configuring the DS2416
The included setup utility is used to assign DS2416 inputs and outputs and
select the wordclock source. Note that some audio software may use its own
input and output assignments and ignore settings made using this utility.
