Imprimir páginaThank you for your purchase of the DAC-40 digital input board. This optional board plays music
signals supplied from the digital outputs of a CD player or similar source. You can connect to the
player using either coaxial cable or optical fiber. You can also use a USB cable to connect to and
play music data from a personal computer. Install this board into an option slot on the rear panel of
your supporting Accuphase analog device, and use its digital input jacks to connect to the external
source.
Note that usage procedures vary according to the device you are using. Please be sure to read
your device's documentation before starting use.

Selecting Your Input
If your device includes a DAC switch...
Use the DAC input switch button to select the input.
Otherwise...
❶ The DAC-40 will automatically lock in the input signal from the ①coaxial, ②optical, or ③USB
connector, in that order, when power comes on or when the input selector is set to OPTION.
❷ To select the input jack to use on the DAC-40 (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.
Note
●
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.

er documentation.
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-40 and an AD-30, AD-20 (Analog Disk Input Board) for
simultaneous use.
How to Install
❶ Turn off the device power.
❷ On the rear panel, remove the slot cover of the slot you wish
to use. (see
)
Fig. 1
◆
Retain the slot for future use.
❸ Insert the board along the top and bottom guide rails in the
slot (see
).
Fig. 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.
Caution
●
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.
●
Do not use electrical contact enhancers or conductivity agents on inputs and cable
connectors. The warranty does not cover damage caused by these materials.
