Operating Voltage
The label above the GPIO connector, and to the left of the mains (AC) connector indicates the AC mains
voltage range for which the LM 26 is approved.
The LM 26 utilizes a universal power supply, and will operate within the range 70-265V~50-60Hz : 30W. If
the plug on the IEC cable provided is not appropriate for your country, a locally-sourced IEC cable with the
appropriate molded plug should be used.
Once a suitable AC power supply is connected, the device can be turned on using the front panel power
button. When turned on, a diagnostic routine is performed and the power button LED changes from red
(Standby) to green (Active).

Grounding
Analog inputs and outputs feature Iso-Float
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-speed transform-
ers and opto-isolators create a barrier between the device and the outside electrical environment.
The Iso-Float feature is activated by default, but
may be disabled via the Lake Controller software,
or via the front panel menu.
Use correctly-shielded balanced audio input connections to minimise hum and interference. Please refer to
section 7.1.5 for further information.
NEVER disconnect the earth (ground) pin on the mains cable (AC power cord).
