NOMENCLATURE AND USAGE OF EACH CONTROL

1) Input Selector Switch

This switch permits proper selection of desired programme
sources. You may set either of the positions (PHONO-l,
PHONO-2, AUX1, AUX-2). Input selection shali be com-
pleted by setting this switch on the corresponding position
to the desired programme sources after connection of
input.

2) Treble Level Control

This is level control to vary the treble response. A clockwise
turn of the knob boosts the treble response, and counter-
clockwise decreases and cuts off. This knob has the
click-stopper of ii points, and yields flat frequency
response at the centre of rotation angle. You can choose a
turn-over (roll-off) frequency at either of 2.5KH2 or 5KHZ
with the selector switch (3).

This level control is of independent structure, and permits
separate control of both left and right channels. The left
one is for left channel and the right one for right channel.
This is convenient for adjustment of different levels
between both channels due to different output of the
speaker systems.
