Rotary Control Knobs
The I/50 has two microprocessor-driven rotary controls for volume, input select, and other limited functionality. Each rotary knob is able to
rotate or can be pressed down.
The left rotary knob selects input and allows entry into the phono control settings. The right rotary knob controls the volume. The volume
range is from 1 to 45. Pressing down on the volume knob mutes and unmutes the I/50. When muted, the LexieTube® display will be
dimmed. The inputs will appear as following on the LexieTube® display: S1 (SE 1 input), or PH (Phono input when module is installed); S2
(SE 2 input); S3 (SE 3 input), or PT (PassThru when engaged); BL (Balanced input). See accompanying instructions with the DAC module
for an explanation of the display functions when installed.
Note: An optional Phono and/or DAC module can be installed in the I/50. The amplifier will automatically recognize when either of these
modules are present and add their functionality to the control system of the I50. There is no software to install when adding modules.
Remote Control Functions
Display
Pressing the display button will cycle the LexieTubes® through various levels of brightness. There are four levels of brightness settings.

Direct Input Selection
The four buttons for input selection are dedicated to each of the four analog inputs - SE1/Phono, SE2, PassThru (SE3), and BL. Select your
desired input by simply selecting it on the remote control.
DAC Functions
The six DAC functions buttons will only work when the DAC module is installed. Please see accompanying instructions with the DAC
