Iso-Float Electronic Balancing
The analog input and output electronic balancing circuits use the Lake Iso-Float system.
The Iso-Float technology combines the benefits of transformer-coupled isolation with the advantages of
clean, direct-coupled inputs and outputs. The audio converters are galvanically isolated, and not connected
to the main ground. High-quality transformers and opto-isolators create a barrier between the device and
possible grounding aberrations from the outside electrical environment.
Iso-Float settings are adjustable via the front panel menu or the Lake Controller software.

AES3 DB25 Connector
A DB25 connector, following the Yamaha pin-out standard, is provided for AES3 connectivity on the LM 26.
This single DB25 connection provides four channels of AES3 input and eight channels of AES3 output as
shown in Figure 7-4 on page 39 below. A detailed wiring reference is provided in Figure 7-8.
