English wordclock master" on page 10. You can select the sampling frequency using mLAN Auto Con- nector or mLAN Graphic Patchbay (page 20). INT: The i88X uses the internal clock at 44.1 kHz. ADAT: The i88X uses the incoming ADAT sig- nal as the master clock. mLAN: The i88X uses the incoming mLAN signal as the master clock. Lit green: The i88X locks to the word- clock master. Flashing green: The i88X is not locking to the wordclock master. C [mLAN ACTIVE] indicator This indicator lights up when the i88X is operating. The indicator turns off when an error occurs during an mLAN operation. When you click the [ID] button in mLAN Auto Connector or mLAN Graphic Patchbay (page 20) to identify the corresponding mLAN device in the network, the indicator flashes. NOTE The indicator also lights up if an mLAN cable is not connected to the unit. D [STANDBY/ON] switch This switch turns the power to the unit on or off (Standby). CAUTION Be sure to follow the procedures described in "Turning the Power to the i88X and Connected Devices On and Off" on page 12 when you turn the power to the i88X on or off. Even when the switch is in the STANDBY position, a small amount of electricity is still flowing to the unit. When you do not plan to use the i88X for an extended period of time, be sure to unplug the AC power adapter from the AC outlet. ■ About the OPTICAL SELECT Switch, MASTER CLOCK Indicators, and Wordclock The function of the OPTICAL IN and OUT jacks (J) specified by the [OPTICAL SELECT] switch (7), and which MASTER CLOCK indicator (B) will light up, varies depending on which mLAN device in the mLAN network is being used as the wordclock master. 1. When the wordclock master in an mLAN network is an mLAN device other than the computer and i88X (that is, when the i88X is using the incoming mLAN signal as the master clock): MASTER CLOCK indicators The [mLAN] indicator lights up. [OPTICAL SELECT] switch DIGITAL: The OPTICAL IN and OUT jacks function as a digital stereo input and output. ADAT NORMAL or ADAT DOUBLE: The sampling frequency in the mLAN network determines the operating mode (NORMAL or DOUBLE). You can select either mode when the OPTICAL IN and OUT jacks are used as the ADAT input and output. 2. When the i88X is referencing the incoming ADAT master clock signal and the i88X has been specified as the clock master in the mLAN network (that is, when the i88X is using the signal from ADAT as the master clock): MASTER CLOCK indicators The [ADAT] indicator lights up. [OPTICAL SELECT] switch DIGITAL: The OPTICAL IN and OUT jacks function as a digital stereo input and output, but the IN jack is unable to receive the ADAT wordclock signal. Therefore, the i88X automatically switches to its internal clock running at 44.1 kHz. (Refer to Case 3.) ADAT NORMAL: The OPTICAL IN and OUT jacks function in ADAT NORMAL mode. ADAT DOUBLE: The OPTICAL IN and OUT jacks function in ADAT DOUBLE mode. 3. When the i88X is not receiving the correct wordclock: MASTER CLOCK indicators The [INT] indicator lights up, and the i88X references its internal clock running at 44.1 kHz. In Case 1, the [mLAN] indicator also lights up. In Case 2, the [ADAT] indicator also lights up. [OPTICAL SELECT] switch DIGITAL: The OPTICAL IN jack functions as the digital stereo input. In this case, you can still monitor analog inputs (from INPUTs 1-8) and digital stereo input (from OPTICAL IN). Therefore, you can monitor the sound from a musical instrument or microphone connected to the i88X without running the computer. ADAT NORMAL or ADAT DOUBLE: ADAT signals are unavailable, although you can still monitor analog input (from INPUTs 18). 10
