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 ber 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

Digital Input Board DAC-60
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
(
Fig. 1
).
◆Retain the sub panel for future use.
❸Insert the option board into the slot, along the slot’s
upper and lower guide rails ( Fig. 2 ). 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 ush with the panel.
❹Secure the board by screwing in the top and bottom
screws.
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 ngers 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 ngers, rmly 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.

 While the above-named units have two expansions slots, they do not have sufcient power to
supporttwo digital inputsboards;soyou can onlyinstall a maximumof one digitalinput board

AD-30,AD-20,AD-10,AD-9).
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.
Cable Connections

COAXIAL Accepts 75-ohm coaxial digital cable.
OPTICAL Accepts JEITA-compliant optical ber cable.
When connecting to a TV, set the digital audio output to PCM.
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).
