High Pass Filters
Each input channel of the Solice mixer is equipped with a continuously variable
high pass filter.
The filters are very useful for eliminating wind rumble and air
conditioning noise. These filters have a 12dB per octave slope and operate from
18Hz up to approximately 200Hz. When turned fully clockwise, the filter is set to
18Hz and your audio signal is flat. As you turn the knob counter clock-wise, the
filter's -3dB cut off point is moved upward. When turned fully counter clock-wise,
the filter is set to its maximum setting and rolls off all signals below 200Hz. As a
general rule, you should only use as much low frequency roll off as needed to get
a good recording.
Equalization
The Solice mixer provides for 3-way equalization.
The High frequency
equalization is centered at approximately 8 KHz.
The Low frequency
equalization is centered at approximately 100Hz. The mid is variable from 1 KHz
to 3 KHz.
Each of the EQ level controls offers approximately +/- 10dB of
adjustment.
Limiters
Each input channel of the Solice mixer is equipped with a precision limiter.
These limiters are switchable on or off via a front panel mounted switch. It is
highly recommended that the input limiters be used at all times. They will save
you from input channel overload and clipping. When turned "On" and when
supplied with audio that is at and beyond the preset activation level, the limiters
begin limiting and the top "0" led of the Pre-fader channel meter will glow RED.
This LED is a two color LED and will also show Green if the audio level is at "0"
dB or above. Thus it is normal to have both segments of the LED lit at once.
This Red and Green lighted at the same time will show up as an Orange color.
This is a perfectly normal condition. The limiters are internally adjustable for both
activation level and for limiting ratio.
The limiters are factory set to activate at
+2dB on the Pre-fader channel meter and they limit at a ratio starting at
approximately 2.7 to 1 up to a ratio of approximately 50 to 1. These ratios were
chosen based on years of customer feedback.
Please note that the limiters
must be adjusted only by qualified technician who has access to precision test
equipment.
Do not try to adjust these limiters yourself.
Calibrating eight
separate limiters without the proper electronic test equipment will lead to poor
results.
Phase Reversal
Each input channel of the Solice Mixer is equipped with an audio phase inversion
switch.
These switches are used when recording with multiple microphones of
different makes and models. Sometime you may encounter a microphone with
