Digital Input Board

Thank 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.

DAC-40 INSTRUCTION MANUAL

Selecting Your Input

If your device includes a DAC switch...

Use the DAC input switch button to select the input.

Otherwise...

The DAC-40 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-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.
	For information about how to set up and use a computer connected by USB, refer to the
	computer's user 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

Turn off the device power.

On the rear panel, remove the slot cover of the slot you wish to use. (see Fig. 1 )

Retain the slot for future use.

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.

Secure the board by screwing in the top and bottom screws.

Illustration shows installation on the E-460.

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.
