3.Setting of loop back
The loop back "C" or "D" button is pushed (C and D
are buttons for i88X). It enters the state of the loop
back if "START" button is clicked on the following
Loopback C screen or the Loopback D screen.
At this time, confirm the thing that mLAN of the
master clock lamp lights. Moreover, the sampling
frequency can be confirmed by keeping pushing the
selection button for one second or more.
*
For the error display
Error 1: The mLAN equipment is not found. Please
confirm the connection.
Error 2: It failed in Audio Loopback. Please set the
loop back again.
Error 3: It failed in MIDI Loopback. Please set the
loop back again.

If the button is clicked, and "START" button is
clicked on the following screen, it is initialized (data
of the factory shipment).
(Should not this inspection usually. )

General audio setting
The following item can be set from a set screen by
clicking "General audio setting" button.
THRU and the word clock mastering switch etc. of
word clock frequency (44.1kHz/48kHz), PLL
response, and SRC can be changed.
Confirm methods of I/O except mLAN
The operation of the main body of i88X can be
confirmed by separating mLAN when mLAN
doesn't operate.
(The mLAN circuit is passed or the ADC output is
connected directly with the DAC input. )
1. Please confirm the operation in either of A or B.
A. The DMSUB circuit board installation screw is
removed and the connector (Fig.1) is connected
instead of the MLN2 circuit board.
B.
The chip resistance on the DM circuit board is
removed, and the jump cable is soldered. (Fig.2)
2. The sound source is connected with the input of
i88X and the thing normally output is confirmed.
*
ADAT is output 6dB low.
