Thank you for your purchase of the DAC-60 Digital Input Board. This option board adds digital input jacks

to your preamp or integrated amp unit. It mounts into an expansion slot on the unit's rear panel, allowing

the unit to play digital source signals. The board provides a USB jack for easy connection to a personal

computer, and an optical fiber jack and coaxial cable connector that accept signals from CD players, TVs,

and other digital sources. Operation of the board—including switching among the inputs, and displaying

the sampling frequency—varies according to the host unit. Please review the documentation that came

with your preamp or integrated amp before using this board.

Included Accessories: "USB Utilities 3" CD and "USB Utilities 3" Setup Guide

Using the DAC-60

❶ Turn off your preamp or integrated amp.

❷ On the rear panel, remove the sub panel of the slot you

wish to use (

Retain the sub panel for future use.

◆

❸ Insert the option board into the slot, along the slot's

upper and lower guide rails (

). When the rear

of the board reaches the internal connectors, give a

gentle push to snap the connection into place, so that

the front of the board becomes flush with the panel.

❹ Secure the board by screwing in the top and bottom

screws.

Caution

Be sure to turn off power to the unit before inserting or removing the board. Leaving the power on

●

may damage the unit.

Do not put objects or insert fingers into the slot. Putting anything into the slot, other than the board

●

itself, may damage the unit.

Do not touch the board's components, soldering, or connector pins, as doing so may cause damage.

●

When handling the board, hold it by its panel face or along the outside of the printed circuit area.

Using your fingers, firmly tighten the mounting screws to secure the board to the panel. Be sure to

●

tighten securely, as looseness may result in damage.

Do not use electrical contact enhancers or conductivity agents on inputs jacks and connectors, as

●

these may cause failure, and lead to a serious accident.

Cable Connections

COAXIAL

Accepts 75-ohm coaxial digital cable.

OPTICAL

Accepts JEITA-compliant optical fiber cable.

When connecting to a TV, set the digital audio output to PCM.

Remove the plug's protection cap.

Retain the protection cap for future use.

USB Port

Before connecting to your computer, install the software from the included USB Utilities 3

CD, as explained in the included documentation.

Use a USB 2.0 cable with a Type B connector. The cable length should not exceed 2

meters (39 in).

USB connection requires bus power (minimum 200 mA).

USB port

Remove the USB dust cover.

Retain the dust cover for future use.

Caution

Do not run multiple cables (USB, coaxial, balanced, and line-level) between the same source device and

your amp unit at the same time. This may create a ground loop, causing humming or other noise.

●

If a DAC-60 mounted in any of the amplifiers named above and used with any of the following

sampling frequencies, it will play these frequencies correctly but will display a value of 192.0 kHz.

Option

PCM: 352.8 kHz, 384 kHz DSD: 2.8 MHz, 5.6 MHz, 11.2 MHz

board

●

While the above-named units have two expansions slots, they do not have sufficient power to

support two digital inputs boards; so you can only install a maximum of one digital input board

into these units. You may, however, install a DAC-60 alongside an analog input board (AD-50,

AD-30, AD-20, AD-10, AD-9).

Selecting the Input Signal

How to Select the Input Signal

Power-off or disconnect the digital source devices you do not wish to

use. The DAC-60 automatically selects from the remaining devices.

Note: If multiple signals are being input, the DAC automatically selects

one, in the following order of precedence: ❶ Coaxial, ❷ Optical,

❸ USB.
