Mixer Main – PEQ
This screen controls and displays the settings for the Mixer
Main Channel parametric equalization.
The PEQ is a 6-band, fully parametric EQ that includes
variable High Shelf and Low Shelf Filters. Bands 1 and 6
may be configured as shelvingfilters.
1. PEQ tab – Selects the EQ screen.
2. PEQ Out/In – Engages / disengages the equalizer.
3. RTA On – Engages / disengages the a real time
analyzer that displays the tonal balance of the
channel’s signal including peak hold indicators.
NOTE: Only one
RTA may be running
on the system at a
time. Touch the RTA
button. If another
device is using the
RTA, the message shown above displays.
NOTE: When the RTA is off, the Parametric
EQ graph expands to use the entire
grapharea.
4. Simple button – Hides the Frequency, and Q controls for all bands. Changing to Simple mode does not affect existingsettings.
5. Reset button – Sets all the PEQ controls to their factory default position.
6. RTA display – Displays the amplitude of the channel signal in 1/3 octave bands. Peak hold indicators are displayed for each band.
• RTA graph vertical scale – Represents audio level from -60 dB to-5dB.
•
RTA graph horizontal scale – Represents frequency from 31.5 Hz to 16 kHz.
7.
Parametric EQ graph – A graphic representation of the equalization curve based on the PEQsettings. The trace dims to indicate that the PEQ
is Out(disengaged).
• EQ graph vertical scale – Represents audio level from -20 dB to+20dB.
• EQ graph horizontal scale – Represents frequency from 20 Hz to 20 kHz.
8. EQ handles – Touch, hold, and drag to change the Frequency and Gain of the associated PEQ band. The frequency band button must be
engaged to see the handles.
9. Low Shelf and High Shelf filter buttons – Changes EQ Band 1 and Band 6 from parametric filters to shelving filters. When a shelf filter is
engaged, the Q control is not available. The low shelving filter raises or lowers a range of frequencies below the set frequency. The high shelving
filter raises or lowers a range of frequencies above the set frequency.
10.
Frequency Bands 1, 2, 3, 4, 5, 6 buttons – Engages / disengages the associated parametric EQ band. Each band is fully parametric with a
frequency range of 20 Hz to 20 kHz.
11. Gain control knob and readout – Adjusts the gain at the frequency setting of the associated EQ band. Range of -15 dB to +15 dB.
12. Freq control knob (Frequency bands 1 – 6) – Sets the center frequency of the associated EQ band. If the Shelving filter is engaged, the Freq
control sets the knee frequency of the shelf filter.
13. Q knob – Adjusts the Q of the associated EQ band. When the Shelf Filter is selected, the Q control is hidden. In addition, Q can be adjusted
by“pinching”.
