m908 User Manual, Rev. G
• clock output Sets the Word Clock output signal source. Options are <clock in, system
clock> When clock in is selected the Word Clock output buffers and re-transmits the
incoming word clock. When set to system clock the Word Clock output transmits the
system clock. Use the system clock setting when the m908 is the clock master in a studio.
• optical input 1 mode Sets the mode for optical input connector 1. Options are
<TOSLINK, ADAT, SMUX>
◦ TOSLINK Stereo PCM. 96kHz maximim sample rate
◦ ADAT 8 channel PCM. 44.1kHz or 48kHz sample rate
◦ SMUX 4 channel ADAT 88.2kHz or 96kHz sample rate
• optical input 2 mode Sets the mode for optical input connector 2. Options are
<TOSLINK, ADAT, SMUX>
◦ TOSLINK Stereo PCM. 96kHz maximim sample rate
◦ ADAT 8 channel PCM. 44.1kHz or 48kHz sample rate
◦ SMUX 4 channel ADAT 88.2kHz or 96kHz sample rate
Note: when changing the mode of an optical connector the input mode will not be
changed until the user clicks the encoder. If the optical mode for the selected
connector has changed, any routes associated with it will be disconnected.
• meter output source Selects the Meter Output source. See Meter Output setup
• meter output routing Enters the Meter Output routing setup screen. See Meter Output
setup.
• backlight Sets the LCD display back-light intensity level. Options are <min, med, high,
max> Adjust the back-light to the lowest level that is acceptable bright for your work
environment.
• display dim Sets the amount of idle time before the display automatically dims. Options
are <off, 10, 15, 20, 25, 30, 45, 60 minutes>.
NOTE: For long display back-light life it is highly recommended to set the display dim to
activate. The backlight dim timer is restarted after any user input on the RCU. If the timer
reaches it's preset time the display will dim. Pushing any of the switches or turning the
encoder knob will bring the backlight back to its normal brightness.
• gpio x mode Sets the mode of the GPIO 1, 2, 3, and 4 pins. Options are <disabled, input,
output> There is a gpio mode parameter for each of the 4 GPIO pins.
• gpio x logic Set the logic level for the GPIO 1, 2. 3, or 4 pins. Options are <active low,
active high> There is a gpio logic parameter for each of the 4 GPIO pins. For logic driven
input functions, the active logic state turns the function on, while the opposite state turns
the function off. For edge triggered input functions the active low setting selects a falling
edge trigger and the active high setting selects a rising edge trigger.
• gpio x input function Sets the function for the selected GPIO 1, 2, 3, or 4 pins when in
