INSTRUCTION MANUAL
Digital Input Board
DAC-30
Note
If installing on an E-308, C-245, or CX-260…
Owing to power limitations, these devices cannot accept more than a single DAC-30. You can,
however, install both a DAC-30 and an AD-20 (Analog Disk Input Board) for simultaneous use.
Thank you for your purchase of the DAC-30 digital input board. This option board accepts digital
music signals from the digital outputs on CD players, MD players, and similar devices, and plays
out the music. You can connect to the player using either coaxial cable or optical fiber. You can also
use USB cable to connect to and play music data on a personal computer. Install this board into
an option slot on the rear panel of your analog device, and use its digital input jacks to connect to
the external source. Usage procedures vary according to the device on which the board is used;
please be sure to read the documentation that came with that device before starting use.
Using the DAC-30
How to Install
Illustration shows installation on the E-460.
COAXIAL
Accepts digital coaxial cable.
OPTICAL
Accepts JEITA-compliant optical fiber cable.
Notes
When connecting a component, please do not connect up both coaxial cable and
(balanced or line (unbalanced)) analog cable at the same time. Simultaneous
connection of both cable types will produce a ground loop, resulting in electrical
noise.
The DAC-30 will automatically lock in the input signal from the coaxial, optical,
or
USB connector, in that order, when power comes on or when the input
selector is set to OPTION.
To select the input jack to use on the DAC-30 (coaxial, optical, or USB): disconnect
the input cables you do not wish to play from, or else switch off the power to the
input devices you do not wish to play from.
◆
For information about how to set up and use a computer connected by USB, refer
to the computer's user documentation.
❶
Turn off the device power.
❷
On the rear panel, remove the slot cover of the
slot you wish to use. (see
Fog. 1
)
◆
Retain the slot for future use.
❸
Insert the board along the top and bottom guide
rails in the slot (see
Fog. 2
).
Push the board in gently until it touches the
connector at the back of the slot, and then give
it a firmer push so that it seats fully into the
connector.
❹
Secure the board by screwing in the top and
bottom screws.
Turn off the device power before installing or removing option boards. Installing
a board while power is on may damage the equipment.
Keep fingers out of the opened slot. Do not place anything other than the board
into the slot.
Avoid touching the board’s soldered areas, connector contacts, and
components. Touching these areas may damage the circuitry or the contact.
Hold the board by the edges or along its panel.
Tightly screw in the two screws all the way (by hand). If screws are loose,
terminals may separate from ground, resulting in poor contact or equipment
damage.

Adds one coaxial input, and one optical-fiber input, and one USB input to the device.
Use these to input digital sound signals from digital components. To select which of the
three inputs is used: Leave the input you do not wish to use empty, or else turn off the
component connected to it.
