Signal Input
Accepts a standard single-ended input pair (RCA) from preamplifiers with
single-ended outputs. Inputs are clearly marked Left and Right, indicated by a
white and red inner ring respectively. Care should be taken to maintain channel
integrity.
Refer to Chapter 13 “Specifications”, for detail on input sensitivity and
impedance.
Earth Lift Switch
This switch isolates the internal signal earth of the amplifier from the mains
earth and is useful if system hum is a problem. Setting this switch down
(EARTH) connects the internal signal earth to mains earth and is the normal
position. Setting to up (FLOAT) disconnects the signal earth from the mains
earth.
Note: Activating this switch has no effect on chassis earth, maintaining the
connection to mains earth.
