Checks for the connection at Plug-in Slot 1, sending/
reception through Control Line, MIDI Line and IN/OUT
through MEL Line. If Insertion Check is successfully
ended, these checks are implemented as follows: (1)
Perform Board Type Request. (2) Receive Type. (3) Check
to see whether it is a VH Board or not. (4) Send TEST
CODE to Plug-in’s MIDI LINE. (5) Check IN/OUT on
MEL Line. (6) Output 1 k.Hz sine wave to Plug-in.
Procedure:
Connect Vocal Harmony Plug-in Board to Plug-in Slot 1
and make sure the following level outputs from Outputs R
and L exist. Before this test, set Master Volume to the max.
Check Item:
 OUTPUT-L: Sine wave, 1 kHz ± 5 Hz, + 5.0 ± 2 dBm
(loading, 10 kΩ; distortion factor, 2.00% or less)
OUTPUT-R: Sine wave, 1 kHz ± 5 Hz, + 5.0 ± 2 dBm
