MID controls the level of the midrange horn (approx. 200–4,000 Hz)
DRIVER GAIN
HIGH controls the level of the high frequency 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

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 fine volume adjustments.
