Section 4 - Transport/DAC
The CD-77 may also function as a dedicated transport or DAC. Rest assured that with AMR’s proprietary jitterless
technology, either as a transport or a DAC, using either USB or S/P-DIF connections, the music signal remains
jitterless.
Before selecting betweem Transport/Integrated/DAC modes, always ensure the CD section is not in use such as
reading the Table of Contents or playing a disc.
4.1 DAC Input (RC-77 only)
The DAC button (RC4) is for the replay of music on the CD-77 from music stored on a computer hard-drive via an
S/P-DIF or USB cable connection.
To establish the connection between the CD-77 and the hard disk source:
i. Power on the CD-77.
ii. On the RC-77 press the DAC button (RC4) to place the CD-77 in DAC mode.
iii. Power ON the personal computer.
iv. Connect the S/P-DIF input or USB cable between the CD-77 and the personal computer.
v. Go to Control Panel > System > Hardware > Device Manager. In Device Manager wait until
the personal computer in Hardware has recognised the CD-77 as a USB Audio Device.
This is located under the Sound, video and game controllers category.
