WideWire Channel Mapping
The WideWire feature of the LS-AES provides alternative multi-wire digital I/O connection modes
for compatibility with legacy third party devices.
WideWire is enabled in the LStream window of the LynxTWO/L22 Mixer. When enabled, alternate
dual and quad wire connections are available, but vary according to the signal sample rate according
to the following table:
WideWire Sample Rates and I/O Modes
Signal Sample

ON/OFF
I/O Mode LS-AES I/O
Frame Rate
44.1k / 48k Either Single-wire 44.1k / 48k
88.2k / 96k OFF Single-wire 88.2k / 96k
88.2k / 96k ON Dual-wire 44.1k / 48k
176.4k / 192k OFF Dual-wire 88.2k / 96k
176.4k / 192k ON Quad-wire 44.1k / 48k
Dual-wire connections require two digital input or output connections to transfer two audio channels.
Quad-wire connections require four digital input or output connections to transfer two audio
channels. In each case, the number of active LStream channels is reduced. The LS-AES inputs and
outputs used for each mode are shown in the following table.
