EINSERT I/O 1 & 2 (TRS phone) jacks
These unbalanced TRS phone-type 1/4" connec-
tors are used for channel insert ins and outs. Use
a split cable to insert an external effects proces-
sor to INPUT 1 & 2 (3) on the front panel.
INSERT I/O 1 corresponds to INPUT 1, and
INSERT I/O 2 to INPUT 2.

The pin configuration is shown below.

FINPUT 3-8 (TRS phone) jacks
These are TRS phone type 1/4" input jacks (bal-
anced). The nominal input level is –20 dBu
through +10 dBu. You can also connect devices
such as synthesizers or rhythm machines with
unbalanced outputs here.
GOUTPUT 1 & 2 / MASTER OUT L & R (TRS

phone) jacks

These TRS phone type 1/4" output jacks (bal-
anced) output an audio analog signal, which is
the combination of mLAN input channels 1 & 2,
and audio monitoring output selected via the
[SELECT] (7) switch on the front panel. The
nominal output level is +4 dBu (pages 16 and
17).
HOUTPUT 3-8 (TRS phone) jacks
These TRS phone type 1/4" output jacks (bal-
anced) output audio analog signals from mLAN
input channels 3-8 respectively. The nominal
output level is +4 dBu.
IDIGITAL STEREO COAXIAL IN & OUT

jacks

These coaxial jacks (RCA pin connectors) input
and output IEC-60958 consumer format digital
audio signals. Connect these jacks to the stereo
input and output of a DAT recorder, MD
recorder, etc., using RCA pin cables for digital
audio.
JOPTICAL IN & OUT jacks
These optical jacks input and output digital ste-
reo or ADAT audio signals. Use the [OPTICAL
SELECT] (A) switch on the front panel to select
DIGITAL STEREO, ADAT NORMAL, or ADAT
DOUBLE mode.
The coaxial and optical digital stereo
input jacks feature a built-in sampling
rate converter (SRC), which enables
audio signals at different sampling fre-
quencies to be input from connected
devices.
KMIDI IN & OUT ports
Connect MIDI equipment here. These ports
enable you to transmit MIDI messages between
a computer or mLAN devices in an mLAN net-
work and a MIDI instrument connected to the
i88X.
LDC IN terminal
Connect the included AC adapter (PA-5D) here.
Be sure to use the included adapter. Using an
AC adapter other than the PA-5D may cause
damage to the i88X, and may even pose a seri-
ous electrical shock hazard. Connect the
adapter to an AC outlet of the specified volt-
age.
MmLAN 1 & 2 connectors
These 6-pin IEEE1394 connectors enable you to
connect the i88X to an mLAN device or
IEEE1394-compatible (FireWire/i.Link) device.
The operation is identical regardless of which
connector is used (mLAN 1 or mLAN 2). If the
target device has a 4-pin connector, use a com-
mercially available 4-pin to 6-pin IEEE1394
cable. Avoid creating a connection loop
(page 23) when connecting the devices.
Yamaha recommends that you use an
IEEE1394 cable with a length of 4.5
meters or less.
