AUDIO SOUND ADJUSTMENTS
The 2 x DRIVER GAIN switches allow the volume of the 2 x horns
to be adjusted in –1.5 dB, O dB (= linear) and +1.5 dB steps.
MID controls the level of the midrange horn (approx. 200–4,000 Hz)
HIGH controls the level of the high f requency horn (above 4,000 Hz)
The factory setting is the "O dB" position for all 2 switches.
Adjustments can be made according to personal taste, to match the
tonal "tonality" of the connected source equipment, or to slightly
correct for room acoustic influences.
In practice, the tonal balance between the 2 x frequency bands can
be changed by up to 3 dB. Example:
If the HIGH switch is set to +1.5 dB and the MID switch is set to –1.5
dB, the relative loudness of the midrange speaker compared to the
tweeter horn is reduced by 3 dB. This could be used as a benef icial
voicing for "shrill" recordings (with overemphasized midrange) or in
an acoustic environment with a "peak" in the midrange.

GAIN ADJUSTMENTS
The 3 x TOTAL GAIN switches allow the adjustment of the gain of
the speakers to the strength of the line level signal f rom the
connected preamp. To avoid sound degrading potentiometers in
the signal path, 3 x switches in an additive stepped arrangement are
being used. Factory default is the “O dB” position for all 3 switches.
Practical example: If a preamp already makes big “jumps” in sound
level by turning the volume knob just slightly, reducing the iTRON’s
input gain by up to –10.5 dB may increase the adjustment angle of
the pre amps volume knob considerably, thus enhancing its
practical usefulness for f ine volume adjustments.
The following steps are possible:
+/– 1.5 dB = left switch in “+” or “–“ position
+/– 3 dB = central switch in “+” or “–“ position
+/– 4.5 dB = central & left in “+” or “–“ position
+/– 6 dB = right switch in “+” or “–“ position
+/– 7.5 dB = right & left in “+” or “–“ position
+/– 9 dB = right & central in “+” or “–“ position
+/– 10.5 dB = all 3 switches in “+” or “–“ position
