iLM8 User Manual
Rear Panel
AES INPUTS - Four 75Ω BNC connectors will accept the AES3 digital audio stream. For iLM8 to work
properly, the following channel inputs must be maintained:
• 1/2 - Left and Right Channel (Front)
• 3/4 - Center and LFE
• 5/6 – Left and Right Surround
• AUX – Left and right Auxiliary
AES OUTPUTS – Four passive 75Ω BNC connectors output the AES3 digital audio stream.
Balanced Digital AES I/O (option 01) – One transformer
Coupled 110Ω balanced I/O connector is provided as per
AES3-1992 standard for using AES format digital audio
over 110Ω twisted pair cable. A standard TASCAM format
DB-25 female connector is included on iLM8 and can
interface directly with your existing equipment.
HD/SDI I/O (option 02) - Two 75Ω BNC connectors handle HD/SDI I/O. One input port as well as one
passive output are present when this option is installed. Supported formats include SMPTE 259M,
SMPTE 292M, and SMPTE 424M as well as ITU-R BT.656 and ITU-R BT.601. See the HD/SDI section
of this manual for more details.
The AES-3id-1995/SMPTE 276M standard dictates a 75Ω unbalanced connection and requires proper
termination. The termination should occur at the destination of the signal (that is, on the inputs to iLM8).
If the loop-through BNC connectors are not feeding additional equipment, terminate each of these with
a standard 75Ω terminator. Like other inputs, HD/SDI signal should also be terminated.
