Analog Outputs - Analog outputs are provided via standard XLR3M connections. The outputs are
1
electronically balanced and feature LAKE Iso-Float circuitry; it is not recommended to use unbalanced connections.
The output impedance is 50 ohms, providing a maximum output level of +21 dBu. Please refer to section 7.1 of
the LM Series Operation Manual for further information.
Analog Inputs - Analog inputs are provided via standard XLR3F latching connectors. The inputs are
2
electronically balanced and feature LAKE Iso-Float circuitry; it is not recommended to use unbalanced connections.
The impedance is 20 kohms (balanced), and the inputs can accept a maximum input level of +26 dBu. Please refer
to section 7.1 of the LM Series Operation Manual for further information.
AES3 I/O - AES inputs and outputs are provided via a 25-pin DB25 connector. Inputs can be received on
3
AES1 (Ch.1,2) and AES2 (Ch.3,4) for all LM Series devices; the LM 44 also allows input from AES3 (Ch.5,6) and
AES4 (Ch.7,8).
Outputs are via AES1 (Ch.1,2), AES2 (Ch.3,4), AES3 (Ch.5,6) and AES4 (Ch.7,8). Please refer to section 7.2 of the
LM Series Operation Manual for further information.
The sample rates available for AES3 inputs and outputs are 44.1, 48, 88.2, 96, 176.4, 192 kHz; input and output
sample rates can be configured to lock to different sample rates.
Primary Network Connector - The primary Neutrik RJ45 etherCON® connection provides integration into an
4
Ethernet control network which may include other LAKE Processors and the LAKE Controller software. Network
connection permits full control of all functions along with real-time metering from a remote position. This device
supports the Dante audio networking protocol, which allows transmission of multichannel, high-definition digital
audio over the same Ethernet connection.
