Solo Switch (Internally Illuminated when activated)
When pressed, this latching switch will route the channel signal to the Solo system (located in the Master
section). This switch illuminates when activated.
High-Frequency Level Control (Shelving)
Adjust the high frequency boost/cut b/- 8 dB; there is a detent at the center “0” position. Boost or cut
of the high frequency level control is usually used for minor tonal adjustments and should be used sparsely for
best sonic results.
Low-Frequency Level Control (Shelving)
Adjust the low frequency boost/cut b/- 8 dB; there is a detent at the center “0” position. Boost or cut
of the low frequency level control is usually used for minor tonal adjustments and should be used sparsely for
best sonic results. The frequency range affected by this low frequency control is directly affect by the position
of the Variable High-Pass filter, keeping the frequencies affected by this control always above the frequencies
that have been attenuated by the Variable High-Pass filter control. Caution should be exercised as to the
amount of boost used when the High-Pass Filter control is set above the 1 o'clock position as to IF any boost
will improve or deteriorate the sonic quality of that channel. Most profession engineers know that the best
sounding EQ is NO EQ.
High-Pass Filter Control
Adjusts the high-pass filter corner frequency between 20Hz and 200Hz at a roll off rate of 12dB per octave.
When turned fully counter clockwise, this control is in the OFF position and has no effect on the channels
signal. This control is used to remove unwanted signal content below the set frequency, such as stage rumble.
The result is usually improved signal quality of the associated input signal while decreasing the amount of low
frequency amplification demand of the audio systems amplifier and speaker combination. This type of filter is
also called a Low-Cut filter. Best result is obtained when set from just above fully clockwise to the 12 o'clock
(control pointer straight up) position. Caution should be used when turn this control greater than the 1 o'clock
position as to much low frequency content may be removed resulting in an unnatural sound. Movement of
this control will also affect the "knee" of the Low Frequency control so it remains usable regardless of the
amount of low frequency content that is removed.
