@) LINE STRAIGHT switch/indicator
By using this switch, the input signals from the various con-
nected peripheral components can be played back through
the amplifier's modifying (tone, mode) circuits, or bypassing
those circuits.
When the indicator is lighted, the function is ON. Input
signals will bypass the modifying circuits and be played back
with pure, flat-balanced tone.
When set to OFF, input signals will pass through the modify-
ing circuits before being played back, thus allowing you to
adjust bass and treble tone, and select the mode of playback
with the MODE selector switch.

the [3 92] or [40 2] position. The 3 ohm and 40 ohm selec-
tion should be made on the basis of the cartridge's load
resistance (impedance) value.
