Unpacking
Handle carefully!
Installation
Installing the 1212 I/O is simple and straightforward. However, to make
sure that you don’t damage the card or the computer, please read the
instructions on pages 2-11
They’re short, they’re sweet, and they’re even sprinkled with a few zippy
graphics–the perfect accompaniment to a brief coffee break.
The 1212 I/O package contains the following items:
• 1212 I/O PCI audio card (don’t remove this from its envelope yet!)
• 1212 I/O software floppy disks for MacOS and Windows 95
• S/PDIF breakout cable
• ADAT sync and Word Clock breakout cable
• ADAT Timecode Conditioner
• This manual
• Warranty card
The package may also contain a bundled software application.

before performing the installation.
Avoid static electricity
The 1212 I/O card is packaged within a protective anti-static envelope,
which prevents static electricity from damaging its delicate electronic
components. It’s a good idea to keep this envelope around; whenever you
need to ship your card, or to store it outside of your computer, put it back
in its envelope.
Before handling the card,
clothes and body by touching a grounded metal surface, such as the case
around your computer’s power supply
hold the card by the metal jack panel (where the connectors are), and touch
the power supply again with your other hand. While working with the
card, avoid moving around on carpeted surfaces–shuffling your feet on a
rug is almost guaranteed to build up a static charge. If you need to walk
around in the middle of working with the card, just repeat the static
discharge procedure before touching the card again.
These simple steps will ensure that a tiny little jolt of static electricity–like
the kind that holds your socks together when they come out of the dryer–
doesn’t zap your card into oblivion.

Hold the 1212 I/O by its edges
Did we already mention that the 1212 I/O uses a whole bunch of delicate
electronic components? Well, OK, so we’ve said it again. To avoid
damaging those lovely little silicon jewels,
edges of the card,
Don’t touch the electronic parts, the PCI connector pins, or any of the traces
on the board (those little silvery paths that run between the components).
There, we’re done nagging now.
Analog levels: +4 or -10
The 1212 I/O’s analog inputs and outputs can be configured for use with
either +4 dBu or -10 dBV signal levels, to allow clean interfacing with a
wide variety of equipment. You can even set the input and output levels
independently, if desired, so that you can record at -10 and play back at +4,
or vice versa.
The 1212 I/O ships from the factory configured for -10 input and output. If
you will be working with -10 levels, then you can jump ahead to the next
section, “Installing the 1212 I/O card in your computer,” on page 5. If you
need to switch either inputs or outputs to operate at +4, read on.
Setting the analog levels
The nominal analog signal levels are set by several
circuit board. A jumper is a small black connector which fits over a pair of
metal pins mounted on the board. The jumper makes an electrical
connection between the pins, just as if you were to solder a wire between
them. Unlike a wire, however, jumpers can be easily installed and
removed. The diagram below shows what they look like:

There are six jumpers on the 1212 I/O circuit board; each one is labeled
with a small “JP” (for “jumper”) followed by a number . The upper group of
four jumpers, labeled JP1 through JP4, set the input level; the lower group
of two, labeled JP5 and JP6, set the output level. The locations of the
jumpers are shown in the diagram below.

To change the nominal input or output levels:
1. Before handling the 1212 I/O card, touch a grounded metal surface
(such as your computer’s power supply). Follow the complete
instructions under “Handle carefully!,” on page 2.
2. Place the card on a clean surface.
3. To remove a jumper, simply grasp it gently but firmly, and then lift
it away from the board.
or:
To install a jumper, slide it gently onto the pins.
4. Repeat for all jumpers within the group: four for input, and two for
output.
4 Korg 1212 I/O
All jumpers within a group must be set the same way: either all installed,
or all removed.
5. If you have removed any jumpers, store them in a safe place.
They’ll be necessary if you ever want to switch the card back to -10dBv
operation.
Installing the 1212 I/O card in your computer
Please consult your compatible computer’s manuals for detailed
instructions on installing a card in your specific system. The instructions
below are a brief overview of the installation procedure.
1. If you have not done so already, read “Analog levels: +4 or -10” on
page 3, and set the 1212 I/O’s levels as desired.
2. Shut down the computer.
3. Detach the power cable from the computer.
4. Remove the computer’s main cover.
5. Choose any available PCI slot.
For each slot, there is a small port on the back of the computer, which
allows access to one end of the card (in the case of the 1212 I/O, this is the
jack panel, into which you plug all your digital and analog connectors).
There will be a small cover over the port.
6. Remove the cover from the port on the back of the computer.
7. Before handling the 1212 I/O card, touch a grounded metal surface
(such as your computer’s power supply). Follow the complete
instructions under “Handle carefully!,” on page 2.
8. Before plugging the card in, align it with the selected PCI slot.
The jack panel should line up with the port on the back of the computer.
There also should be a corresponding guide towards the front of the
computer, to hold the other end of the card in place.
9. Press the card gently but firmly into the slot, until the connector is
fully inserted.
Don’t force the card into the slot. If you encounter a lot of resistance, pull
the card out and try inserting it again.
10. To make sure that the connector is properly inserted, pull on the
card gently.
If the card resists your gentle pull and stays in place, then it’s inserted
properly.
If it moves easily, then go back to step 9 and try again.
11. After installing the card in the slot, replace the computer’s main
cover and power cable.

extensions must be loaded before the card can be used.
11. After successfully re-starting with the 1212 I/O extension loaded, reenable any installed virus detection extensions.
Virus detection software will only interfere the first time that the 1212 I/O
extension loads.
Installing the 1212 I/O software (Windows 95)
The 1212 I/O includes several important pieces of software for
Windows 95-compatible computers. Some of this software is driver
software, which you can just install and forget about, but two programs–
the 1212 I/O Utility, and the 1212 I/O Wave Device Control–allow you to
control various aspects of the 1212 I/O.
The 1212 I/O Utility program offers quick and easy access to the routing
and mixing features of the card. The 1212 I/O Wave Mixer offers various
controls for using the card as multiple Wave devices, including
synchronization of each device for playback and record, and settings for
each device’s volume and balance.

Korg engineers worked valiantly to squeeze an incredible number of
inputs and outputs onto the 1212 I/O’s relatively small jack panel. To
produce such a densely packed piece of digital audio real estate, they used
a number of breakout cables–that is, cables with a single connector on one
end, fanning out to two or three connectors on the other.
The analog inputs and outputs use 1/4” TRS (tip-ring-sleeve) connectors to
carry stereo, unbalanced signals, similar to a stereo headphone jack. You
can use standard “insert” cables to bring these signals out to a pair of 1/4”
mono connectors. We’ve provided special, custom cables for use with the
S/PDIF and Word Clock & ADAT Sync connectors.

This input is used to bring analog signals into the 1212 I/O. You can
connect this to the output of a mixer, microphone pre-amp, synthesizer,
and so on. To allow use with a wide range of equipment, the analog input
may be configured for either +4 dBu or -10 dBV signal levels. For more
information, please see “Analog levels: +4 or -10” on page 3.
Microphones and electric guitar outputs should be sent through a mixer or
pre-amp first, to bring them up to +4 or -10 levels; otherwise, their signals
will be too weak.
The analog input uses a 1/4” TRS (tip-ring-sleeve) connector to carry a
stereo, unbalanced signal. The tip carries the right side, the ring carries the
left side, and the sleeve carries the ground. You can use standard “insert”
cables to bring the signals out to a pair of 1/4” mono connectors.

Alesis BRC; this is necessary when transferring audio from S/PDIF input
to ADAT output in a BRC-equipped system.
As with the Word Clock input, above, the Word Clock output requires a
shielded, video-quality cable, with 75-ohm or greater impedance.
ADAT Timecode Conditioner
The 1212 I/O’s ADAT Timecode Conditioner is a small device which fits
between the ADAT 9-pin sync cable and the 1212 I/O’s ADAT timecode
connector. This device pre-conditions the ADAT timecode, enhancing the
1212 I/O’s timecode sync capabilities.
If you will be using ADAT timecode with the 1212 I/O, please make sure
that the ADAT Timecode Conditioner is connected between the ADAT sync
cable and the ADAT sync connector on the 1212 I/O’s ADAT sync input.

Word clock settings
Using only the 1212 I/O’s analog input and output
1212 I/O into a variety of different setups. By its nature, the instructions
here are brief; for additional detail, please consult the manuals of the other
digital audio hardware and software being used.
The great majority of technical support questions regarding the 1212 I/O
are the result of incorrect wor d clock settings. Incorr ect wor d clock settings
may cause subtle degradation of audio, louder pops and clicks, altered
playback speeds, and/or timecode problems.
Keeping track of the word clock source may seem confusing at first, but it’s
really pretty simple. Just remember that, as with SMPTE synchronization
setups, there must be one and only one word clock master, with all other
devices set to slave to the master device. This means that you need to keep
track of the word clock settings on all of your digital audio devices–not just
on the 1212 I/O.
The 1212 I/O can be used as a stand-alone analog I/O card, without any
digital connections. In this case, set the 1212 I/O’s word clock source to
Internal.
S/PDIF devices (DAT, effects, etc.)
There are two broad classifications of S/PDIF devices: those which can use
an external clock to control their digital output, and those which cannot.
These two types require different settings on the 1212 I/O.
Devices which do not accept external word clock
Many S/PDIF devices don’t have a separate setting for the word clock
source. For instance, many DAT machines automatically use incoming
digital audio data as the word clock source when recording, and
automatically use the internal clock source when playing back. Some
stand-alone A/D converters also may not accept an external word clock.
When recording from such devices, all the other devices must slave to the
S/PDIF device’s clock.
1. Connect the digital audio cables between the S/PDIF input and
output of the 1212 I/O and the S/PDIF device.
2. When recording from the S/PDIF device into a digital audio
program, set the 1212 I/O’s word clock source to S/PDIF•Word
Clock.

System Configurations
In Deck, set the Sync Mode to Digital. For more information on word clock
settings in audio software, please see “Setting the word clock source in
digital audio software,” on page 16.
3. When playing back into the S/PDIF device from a digital audio
program, set the 1212 I/O’s word clock source to Internal (or ADAT,
if you generally use an ADAT system as the master clock source).
Devices which accept external word clock
Some S/PDIF devices, on the other hand, may allow you to freely select
between internal and external word clock. Some may use a dedicated word
clock input; others may use the clock signal received at their S/PDIF input.
When using the 1212 I/O with these devices, you don’t need to change
word clock settings between recording and playback. Instead:
1. Connect the digital audio cables between the S/PDIF input and
output of the 1212 I/O and the S/PDIF device.
2. If the S/PDIF device has a dedicated word clock input, connect the
word clock output of the 1212 I/O to the word clock input of the
S/PDIF device.
3. Set the S/PDIF device to use the external clock source.
4. In the digital audio program, set the 1212 I/O’s word clock source to
Internal or ADAT, as desired.
You can also use a dedicated word clock source as the master for the
1212 I/O. In this case, connect the word clock output of the master device
to the word clock input of the 1212 I/O, and set the 1212 I/O’s word clock
source to S/PDIF•Word Clock.

Korg 880D/A
The 880D/A provides the 1212 I/O with an additional 8 high-quality
analog outputs. The 880D/A connects directly to the 1212 I/O’s ADAT
optical output, so setup is very simple.
1. Connect the optical output of the 1212 I/O to the optical input of the
880A/D.
You don’t need to make any word clock settings on the 880D/A; it will
automatically slave to its ADAT optical input.
2. In the digital audio program, set the 1212 I/O’s word clock source as
desired.
If you are using the 1212 I/O and 880D/A as a stand-alone system, set the
word clock source to Internal. If you are using the 1212 I/O in combination
with other digital audio devices, see this manual’s instructions for those
devices.

The 880A/D provides the 1212 I/O with an additional 8 high-quality
analog inputs. The 880A/D connects directly to the 1212 I/O’s ADAT
optical input, so setup is very simple.
First, connect the cables:
1. Connect the Word Clock output of the 1212 I/O to the Word Clock
input of the 880A/D.
2. Connect the optical output of the 880A/D to the optical input of the
1212 I/O.
Next, make all the word clock settings:
3. On the 880A/D, set the CLK. SOURCE to EXT.WCLK.
This makes the 880 A/D sync to the word clock output of the 1212 I/O.
4. In the digital audio program, set the 1212 I/O’s word clock source as
desired.
If you are using the 1212 I/O and 880A/D as a stand-alone system, set the
word clock source to Internal. If you are using the 1212 I/O in combination
with other digital audio devices, see this manual’s instructions for those
devices.
Korg 880A/D and 880D/A
This setup combines the 1212 I/O with the Korg SoundLink DRS 880A/D
and 880D/A to create a system with 10 analog inputs and 10 analog
outputs. The1212 I/O provides the master word clock, and both the
880A/D and 880D/A slave to the 1212 I/O.
To use the 1212 I/O with both the 880A/D and 880D/A, simply follow the
directions under “880D/A” and “880A/D,” above.
880A/D and 880D/A, recording from a S/PDIF device
If you like, you may also record simultaneously from a S/PDIF device
(such as a DAT, or an external A/D). This will allow you to record up to 12
tracks simultaneously from an S/PDIF source, the 880A/D, and the 1212
I/O’s analog inputs.
You may or may not need to change the 1212 I/O’s word clock source to
S/PDIF•Word Clock; the 880A/D and 880D/A can remain as described
above. For more information, see “S/PDIF devices (DAT, effects, etc.)” on
page 12.
Korg 168RC
This setup combines the 1212 I/O with the Korg SoundLink DRS 168RC
