3. OPERATION INFORMATION
3.1
1) Connect an optical or coaxial S/PDIF signal to the S/PDIF input (OPT1 or J5).
2) Connect the output to either headphones or an analog analyzer. If using the RCA test jacks
3) Verify that all power supplies are turned off and:
4) Once power is applied the volume LEDs will illuminate. Adjust settings as required with but-
6
a. Connect +5.0 V to the terminal marked +5 V (J4).
b. Connect from +1.8 V to +2.4 V to the terminal marked VD_HP (J6).
c. Connect from +1.8 V to +2.4 V to the terminal marked VA_IN (J7).
d. Connect the power supply common ground to the terminal marked GND.
e. Verify that all power supply output voltages are set correctly to correspond to the setting
(J8 and J9) a 16 Ω dummy load is provided in circuit. If using the headphone jack (J3) please
use a 16 Ω dummy load or 16 Ω headphones.
tons - note that the volume, bass, and treble buttons do not 'ramp' and must be pushed for
each increment/decrement. The volume level will initialize at -24 dB.
