iLM8 – Live User Manual
GPO has two options to choose from within the I/O menu in System Settings. GPO 1 & 2 can
be used for Alarm conditions or to monitor the ‘OVER’ and ‘UNDER’ target levels from the Mix
Monitor.
Output 1: Relay 1 is Normally Open. Alarm Option: Upon an AES lock loss failure, this relay
will close. When the failure is remedied, the relay will open. Mix Monitor Option: High – active
for ‘OVER’ target loudness.
Output 2: Relay 2 is Normally Open. Alarm Option: Upon a hardware failure (i.e. Power
Supply or Internal Communications Failure), the relay will close. When the failure is remedied,
the relay will open. Mix Monitor Option: High – active for ‘Under’ target loudness.
Input 1: Momentary voltage detected on this port will cause iLM8 - Live to toggle stop then reset
the infinite average for the surround and stereo inputs.
Input 2: Momentary voltage detected on this port will cause iLM8 - Live to toggle pause then
resume calculating the infinite average for the surround and stereo inputs.
NETWORK - Used for logging or to update iLM8 - Live’s firmware. To connect directly to a PC without
use of a network switch or hub, a crossover cable is required. Firmware updating is accomplished via
UDP Port 44600. Please refer to the iLM8 - Live Remote Dashboard section of this manual for more
details on logging, or the Firmware Update section of this manual for the update procedure.
PSU 1 - IEC320 port to connect to AC Mains. The internal power supply is auto switching and will work
on 120VAC-60Hz or 240VAC-50Hz electrical power systems with a maximum total current draw of 25W
(>.25A 120VAC or >.15A 240VAC).
Please connect iLM8 - Live to a properly grounded uninterruptible power supply (UPS) to
protect against power surges and low-voltage conditions. iLM8 - Live may be combined with other
devices on the output of the UPS as long as the total load is within the UPS’ capacity. Consult your
UPS manual for details.
HD/SDI
iLM8 - Live can use an optional factory-installed HD/SDI I/O module to measure audio directly
embedded into an SDI stream without any additional required equipment.
The HD/SDI module contains 3 Gb/s SDI technology and will auto-detect the signal, whether SD, HD or
HD 3Gb/s format. Audio will be automatically extracted from popular video standards such as: NTSC
525/29.97, PAL 625/25, 1080i/59.94, 1080i/50, 1080PsF/23.98, 1080PsF24, 720p/59.94 and 720p/50.
The sample rate of extracted audio is converted to 48 kHz, 24 bit resolution regardless of the source
material and is available as AES audio at iLM8 - Live’s output jacks
