4-4-3. MIDI In/Out Check
By connecting the MIDI IN and OUT ports, this test checks if the reply against the ID inquiry is correctly received. If
not, the prompt below will be displayed.
4-4-4. S/P DIF In/Out Check
By connecting the DATA IN and OUT terminals, this test checks if the S/P DIF signal output by itself is correctly
received. If the PLL circuit is not in a “LOCKED” condition, the prompt below will be displayed.
4-4-5. Adat In/Out Check
By connecting the DA TA IN and OUT terminals, this test checks if the ADAT digital signal output by itself is correctly
received. If the PLL circuit is not in a “LOCKED” condition, the prompt below will be displayed.
4-4-6. Phantom Voltage Check
When the following is displayed, phantom power (DC +48V) is supposed to be applied between the pin-2 (HOT) and
pin-1 (GND) / pin-3 (COLD) and pin-1 (GND) of XLR balanced input jack. Check the voltage between the pins using
a multimeter, etc. Pressing the [ENTER/YES] key would forward the Self Check test.
4-4-7. A/D and D/A Circuit Check (Input Monitoring)
The VF-16 automatically checks the before mentioned points in the Self Check mode. If the VF-16 is working properly,
the following will appear on the LCD and the VF-16 is automatically put into Input Monitoring mode.
