(5).Once USB driver is installed, press S key on the front panel or the USB key on the remote
control to input signals. Also, the signal option of the menu can be set as
“
USB
”
, then the USB
input function is on and the screen is switched to
“
USB INPUT
”
interface.
7. Coaxial Input
Coaxial input can improve the sound of the input digital signal. No matter TV STB, DVD, high
definition player, low-end CD player, Bluetooth or WIFI, the voice will become nicer after the
signal optimization and re-arrangement of QA661 circuit as long as it has coaxial output and is
able to input to QA661.
(1).Connect the coaxial output of your device with one end of the coaxial cable and connect the
other end with the coaxial interface with EXT COAX symbol printed on the rear panel of
QA661.
(2).Turn on the power switch of QA661, press S key on the front panel or COAX key on the
remote control to select the coaxial input signal. Also, the menu signal can be set as
“
Coaxial
”
,
the coaxial input function is turned on and the screen is turned to
“
COAXIAL INPUT
”
interface.
8. Word Clock Input
QA661 has a word clock output of nice parameters and total electrical isolation when it uses an
internal player. If your DAC also has word clock input, such as Hilo, use a BNC cable to connect
DAC word clock input, then the working clock on DAC synchronizes with the player and the
sound quality will be improved on a further level.
(1).Connect one end of BNC cable with the BNC interface with WORD CLOCK symbol printed
on the rear panel of QA661, and the other end with the DAC with word clock input function.
(2).Set DAC asynchronous clock source as the word clock input.
