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. To external processor input To INSERT I/O Sleeve Ring Tip Sleeve Tip To external processor output F INPUT 3-8 (TRS phone) jacks These are TRS phone type 1/4" input jacks (balanced). 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. G OUTPUT 1 & 2 / MASTER OUT L & R (TRS phone) jacks These TRS phone type 1/4" output jacks (balanced) 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). H OUTPUT 3-8 (TRS phone) jacks These TRS phone type 1/4" output jacks (balanced) output audio analog signals from mLAN input channels 3-8 respectively. The nominal output level is +4 dBu. I DIGITAL 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. J OPTICAL IN & OUT jacks These optical jacks input and output digital stereo or ADAT audio signals. Use the [OPTICAL SELECT] (A) switch on the front panel to select DIGITAL STEREO, ADAT NORMAL, or ADAT DOUBLE mode. NOTE The coaxial and optical digital stereo input jacks feature a built-in sampling rate converter (SRC), which enables audio signals at different sampling frequencies to be input from connected devices. K MIDI IN & OUT ports Connect MIDI equipment here. These ports enable you to transmit MIDI messages between a computer or mLAN devices in an mLAN network and a MIDI instrument connected to the i88X. L DC IN terminal Connect the included AC adapter (PA-5D) here. WARNING 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 serious electrical shock hazard. Connect the adapter to an AC outlet of the specified voltage. M mLAN 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 commercially available 4-pin to 6-pin IEEE1394 cable. Avoid creating a connection loop (page 23) when connecting the devices. NOTE Yamaha recommends that you use an IEEE1394 cable with a length of 4.5 meters or less. 11
