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 DS2416s ve DSPs take the load off the computers 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 DS2416s 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 industry-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-channel analog inputs and outputs, with 20-bit 128-times oversampling A/D converters 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 inputstwo of which can be used with microphonesfour 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.

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 computer 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. Its compliant with PCI version 2.1, requires one IRQ (interrupt request), but no DMA (Direct Memory Access). Since its a PCI card, IRQ settings are made automatically. PCI bus speeds other than 33 MHz are not supported. 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 performance will depend on the capabilities of your computer and audio software.

Compatible Software

Any software that supports Windows MME (Multimedia Extensions), including the Windows 95 Media Player accessory, can be used with the DS2416 for recording and playback. To use the mixing functions, however, requires software that supports the DS2416 mixer. The following software companies are supporting the DS2416. C-Mexx Cakewalk Canam Computers Emagic IQS (Innovative Quality Software) Musicator SEKD Sonic Foundry Steinberg

Installing the DS2416

The DS2416 installs into a PCI expansion slot and requires no special jumper settings or interrupt settings. See your computers manual for full details on installing PCI cards.
1 Turn off the computer and disconnect the power cord. 2 Remove the computers 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.
Important: The DS2416 is grounded via the expansion-card xing screw, so be sure to tighten it securely. 6 Replace the computers 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
oppy disk into the oppy disk drive, and then click OK. The driver software is installed, and the Windows 95 desktop appears as normal.

Conguring 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.

Wordclocks

Unlike analog audio equipment, digital audio equipment must be synchronized when digital audio is transferred from one device to another, otherwise, the digital audio might not be read correctly and audible noise, glitches, or clicks may occur. Synchronization is achieved using whats called a wordclock, which is a clock signal for synchronizing all the digital audio words in an audio system. Note that wordclocks are not the same as SMPTE or MIDI timecode, which are used to synchronize audio recorders, MIDI sequencers, and so on. Wordclock synchronization refers to the synchronization of the digital audio processing circuits inside each digital audio device. In a typical digital audio system, one device acts as the wordclock master and the other devices act as wordclock slaves, synchronizing to the wordclock master. If the DS2416 is the only digital audio device in your system, no special wordclock settings are required, as the DS2416 synchronizes to its own internal wordclock. Add a DAT recorder or digital multitrack recorder, however, and you must decide which device to use as wordclock master and which devices to use as slaves. Even when youve done this and congured your system, it may sometimes be necessary to change the wordclock settings, such as when recording from a DAT or CD player. Wordclocks run at the same frequency as the sampling rate. The DS2416 generates its own wordclock at 44.1 kHz (the industry-standard sampling rate for music CDs) or 48 kHz and can be used as wordclock master. Alternatively, it can be used as a wordclock slave synchronized to an external wordclock of between 30.08 kHz and 50.88 kHz (32 kHz 6%, 48 kHz +6%). Converting the sampling rate of digital audio is a complicated process, so its best to use the 44.1 kHz sampling rate, especially if your work is destined for CD distribution. Wordclock signals can be distributed via dedicated cables or derived from standard digital audio connections, such as the D IN connection on the DS2416. With Coaxial digital audio connections, a wordclock signal is transmitted even when no audio signal is present. In a system where all devices share a common wordclock, its important that all devices be turned on even when theyre not being used. Turn on the wordclock master rst, and then the slaves. When shutting down the system, turn off the slaves rst, and then the master. Before commencing with a recording session, make sure that all wordclock slaves are synchronized to the master. Some devices have front panel indicators to show when they are wordclock synchronized. Refer to the instructions for each device.

Recording Digitally to DAT
Recording Digitally to the DS2416
In this example, a DAT deck is connected to the DS2416 D IN connector for digital recording. The DS2416 works as wordclock slave and the DAT works as wordclock master.

Digital Out

DS2416 (wordclock slave)

In this example, the D OUT connector on the DS2416 is connected to the digital input of a DAT recorder for digital mixdown recording. The DS2416 works as wordclock master and the DAT works as wordclock slave. When the digital input on the DAT recorder is selected as the recording source, the DAT should automatically synchronize to the wordclock signal coming from the DS2416. On some DAT recorders, the wordclock source may have to be set separately. Refer to the instructions supplied with your DAT recorder.

Connecting an SW1000XG Sound Card
The Yamaha SW1000XG PCI Sound Card features an XG tone generator, onboard effects, MIDI interface, and analog inputs, and by connecting it to the I connector on a DS2416, its outputs can be digitally connected to the DS2416 mixer via its sub inputs. Note that you cannot use an SW1000XG card with two digitally cascaded DS2416 cards.
1 Install the DS2416 and SW1000XG cards in your computer. 2 Using the supplied 14-pin to 16-pin cables, connect the I con-
nector on the DS2416 to the ?? connector on the SW1000XG, as shown below.

to connector I (sub inputs).
DS2416 Q&A (Questions & Answers)
Q Whats a DSP? A A DSP, or Digital Signal Processor is a processor optimized for
real-time digital data processing. The DS2416 features the same DSP as the Yamaha 02R and 03D digital mixing consoles.

Q At what wordlength is digital audio processed? A The EQ features a 44-bit data path, 32-bit coefcient, and 54-bit
accumulator. All other mixer sections feature a 32-bit data path, 24-bit coefcient, and 42-bit accumulator.
Q Does the DS2416 have any onboard memory? A Yes, 3 megabytes, which is used for input, and effects delays. Q What is the available recording time? A This is dependent on the software and selected wordlength Q How do I synchronize the DS2416 to MIDI Clock, MTC, or SMPTE

timecode?

A The DS2416 receives timing information from the controlling soft-
ware, so if the software supports external timecode, so does the DS2416.
Q Can DS2416 mixer functions be controlled via MIDI? A If the controlling software supports this, yes. Q How good are the onboard effects processors? A As good as those used in the Yamaha ProR3 and REV500 effects

processors.

Q Can the DS2416 be used simultaneously with a Sound Blaster or

Korg 1212 I/O card?

A Yes.

Troubleshooting

Trouble Advice Make sure that the computer is turned on. Make sure that the DS2416 is inserted in the PCI bus slot correctly. Make sure that the DS2416 input and outputs are correctly assigned using the controlling software. The DS2416 does not work? In older computers, some PCI slots may not function as the bus master, and the DS2416 will not work in such slots. See your computers manual for more details. Some PCI cards may conict with the DS2416. Try removing cards, or swapping slots with the DS2416.
