AND OUTPUT
With this button depressed the filter set is in
the 1/3 octave mode, and with this button
out, in the 1/1 octave mode. When the filter is
set in the 1/1 octave mode, there will be three
adjacent positions on the dial for each 1/1
octave filter. The centre frequency of the
selected 1/1 octave filter is indicated in the
centre position.
The two frequency ranges I and II are 25 Hz-
20kHz, D, A, B, C and Linear, and 2Hz- 160
kHz respectively. The Type 1614 contains
both ranges, but the Type 1615 contains only
the filters in range I. On the dial of the 1614,
the two ranges are distinguished by the bold
circles.
When
the 50-position switch is placed out-
side the frequency range of the 1615 there
will be no output from the filter set.
Also no output will appear in the 1614 at the
same positions of the filter switch, whilst fre-
quency range I is selected.
