Input Channel - Peq - QSC MP-M80 User Manual

Input Channel − PEQ
This screen controls and displays the settings for the
Input Channel parametric equalization.
The PEQ is a 4-band, fully parametric EQ that includes
variable HPF (High Pass Filter) & LPF (Low Pass Filter).
• The HPF is variable with a range of 20 Hz
to 2,000 Hz. It passes frequencies above
the setting while cutting those below.
• The LPF is variable with a range of 1 kHz
to 20 kHz. It passes frequencies below the
setting while cutting those above.
• Bands 1 and 4 may be confi gured as
shelving fi lters.
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 to the right 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 and low and high cut fi lters. 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. High Pass and Low Pass buttons – Engages / disengages the HPF and LPF (described above).
10. Low Shelf and High Shelf fi lter buttons – Changes EQ Band 1 and Band 4 from parametric fi lters to shelving fi lters. When a shelf fi lter is
engaged, the Q control is not available. The low shelving fi lter raises or lowers a range of frequencies below the set frequency. The high shelving
fi lter raises or lowers a range of frequencies above the set frequency.
11. Frequency Bands 1, 2, 3, and 4 buttons – Engages / disengages the associated parametric EQ band. Each band is fully parametric with a
frequency range of 20 Hz to 20 kHz.
12. Nain control knob and readout – Adjusts the gain at the frequency setting of the associated EQ band. Range of -15 dB to +15 dB.
13. Freq control knob (Frequency bands 1 – 4) – Sets the center frequency of the associated EQ band. If the Shelving fi lter is engaged, the Freq
control sets the knee frequency of the shelf fi lter.
14. 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".
15. Freq control knob (Low and High Cut) – Sets the frequency of the low and/or high cut fi lter as measured from a point 3 dB below 0 or unity.
