Using the LIO-8 Hardware
LIO-8 Front Panel
Figure 6.3: LIO-8 Front Panel
The front panel provides LIO-8 system control and status at a glance (The Front Panel includes features
that are only enabled if you install one or two of available add-on Mic Pre boards. When no Mic Pre boards
are installed, these features are disabled and are present for future expansion. The Mic Pre related features
are noted below.):
• Monitor - Select the Monitor Controller input or output
• Preset - Recall one of the eight stored system configurations
• Input - Step through the available input sources (only active if fitted with optional mic pres)
• Link - Link multiple input and output encoders for stereo or multichannel use
• +48 - Enable phantom power, per channel (only active if fitted with optional mic pres)
• U/M - User mode (for future expansion)
• Power switch for rear 4 pin XLR connector (jumper defeatable)
• Sample Rate (nominal 44.1, 48, 88.2, 96, 176.4 or 192KHz)
• The Sample Rate is determined from the currently selected clock source so it will accurately indi-
cate the current sample rate, even when the clock source is being provided by an external device.
• Clock source:
• Internal indicates that the system is internally clocked
• Wordclock indicates that system is being clocked from the wordclock input
• Digital In indicates that the system is being clocked from the selected digital input
• Control Mode — Indicates what parameters the encoders are modifying:
• I/O Trim — Indicates whether you are modifying input or output channel gain.
• Input Status - Indicates mic input, line input or mic s/r by channel (fixed on “Line” if no Mic Pre is
fitted).
• Encoders - Eight detented encoders for multipurpose control, with push-switches.
• 15-segment metering for the 8 analog inputs and outputs using multicolor LEDs, which also display
gain values during encoder use. The meters are fast PPM peak reading meters with auto-resetting
peak holds.
• SysLock — Indicates that the system clock recovery circuit is properly locked to the selected clock
source. If this light is not illuminated, the LIO-8 will not be locked to a clock and will revert to its
