Technical description
Signal processing
L-ISA Processor II has no SRC capabilities. Therefore, the input audio streams sample rate must match the DSP
sample rate, and the output streams match the DSP sample rate.

Signal inputs
L-ISA Processor II features three BNC MADI input connectors and two Ethernet ports allowing it to process up to 128
inputs selected from:
• 64 AVB channels (8 redundant streams of 8 channels) and 96 MADI channels at 96 kHz.
• 64 AVB channels and 192 MADI channels at 48 kHz.
To maintain the phase relationship between inputs into the L-ISA Processor II, it is recommended not to mix MADI
and AVB channels from the same device due to latency differences of the stream formats (>1 ms).
In addition, L-ISA Processor II features one XLR input connector capable of retrieving two AES/EBU channels.
MADI
L-ISA Processor II can receive up to 192 channels at 44.1 kHz / 48 kHz or up to 96 channels at 96 kHz, using the three
MADI input BNC connectors on the rear panel.
AES/EBU
L-ISA Processor II can receive two AES/EBU digital audio channels at 44.1 kHz, 48 kHz, or 96 kHz using the AES/EBU
input connector on the rear panel.
The connector is a female XLR3.
Milan-AVB
Eight redundant AVB streams of up to eight channels may be connected to L-ISA Processor II, for a total of 64 AVB
channels. One CRF stream may also be connected to L-ISA Processor II.
Each Ethernet port uses a high speed data transfer protocol up to 1 Gb/s and supports the Milan AAF PCM32 stream
format, with stream frequencies of 48 kHz or 96 kHz.
