Remote Control only Functions
Input Buttons: Allows direct selection of each of the 7 inputs of the SP20.
Please note that input SE4 is user-selectable to function as a unity gain
(processor) input. When engaged and SE4 is selected, ‘Unity Gain’ will
appear in the display and the volume control will be defeated. Before
selecting the unity gain input, be sure to turn down the volume on your
connected processor/source.
BAL/SE: Select as appropriate for each input. For source components
having balanced (XLR) connections to the SP20, select BAL. For single-
ended (RCA) sources, select SE. Once selected for an input source, the
setting is memorized.
Invert: Inverts absolute phase of the output signal.
Mono: Sums L and R input for mono output from any source selected.
Display Down/Display Up (DSP DN/DSP UP): Decreases/increases
display timeout; for more information about the timeout screen see ‘Display’

appears in display window as movable marker on bar graph. Useful for
compensating for uneven speaker placement or imbalanced output from a
source component.

have been in service. NOTE: After replacing tubes, this function should
be reset to ‘0’. See further instructions under ‘Hours Meter’ in the section
