Using The Flex15Geq - Yamaha QL5 Reference Manual

Using the Flex15GEQ

You will use the Channel Strip section's faders and [ON] keys to control the Flex15GEQ.
A rack in which a Flex15GEQ is mounted will show information for two GEQ units (A and B)
in the VIRTUAL RACK window.
NOTE
If you mount a Flex15GEQ, two monaural 31BandGEQ units will be placed in a single rack.
However, only up to fifteen bands can be adjusted for each unit.
STEP
1. Press the rack container in which you mounted Flex15GEQ.
2. Press the GEQ ON/OFF button to turn the Flex15GEQ on.
3. Press one of the buttons in the FADER ASSIGN field to select the group of bands you
will control.
4. Use the faders in the Channel Strip section to adjust the selected band.
5. When you've finished making settings, turn off the buttons in the FADER ASSIGN
field.
NOTE
• When a fader in the Channel Strip section is set to the center (flat) position, the corresponding
[ON] key indicator will turn off. This indicates that the corresponding band is not being modified.
If you raise or lower the fader even the slightest amount, the [ON] key will light, indicating that this
band has been modified.
If you press a lit [ON] key to make it go dark, the corresponding band will immediately return to
the flat state. If you press the [ON] key once again, the value that was modified is shown.
However, please note that if the [ON] key for this band is off and if you press the [ON] key for the
fader of a different frequency band, the adjusted gain value will be canceled and will return to
±0dB.
• If you switch the display to a different screen, the fader assignments in the Channel Strip section
will forcibly be defeated. However if you once again display the same rack, the group of bands
you had previously been controlling will automatically be assigned to the faders.
• When you close the GEQ window, the buttons in the FADER ASSIGN field automatically turn off.
GEQ EDIT window (Flex 15GEQ)
This window is the same as that for the 31BandGEQ, except that the AVAILABLE BANDS
parameter box indicates the real-time number of additional bands (maximum 15) that
can be controlled in the current GEQ.
For a rack in which a Flex15GEQ is mounted, the rack switch tabs will be split as xA and
xB (x is the rack number).
Parametric EQ operations
In addition to the standard 4-band EQ, QL series consoles also feature an 8-band parametric
EQ (PEQ) that can be rack mounted. You can mount this PEQ in GEQ racks 1-8 and patch it
to the insert-out/in of an input channel (GEQ 1-8 rack only), a MIX/MATRIX channel, or a
STEREO/MONO channel. You can also mount it in EFFECT racks 1-8 (FX 1-8) and patch it
to the insert-out/in of an input channel, MIX/MATRIX channel or STEREO/MONO channel.
The gain of each band can be adjusted using the Centralogic section's faders and [ON] keys.
The following type of PEQ is provided.
8BandPEQ
This is a monaural 8-band PEQ. There are also an independent HPF, LPF, and 3 notch filters.
Two 8BandPEQ units (shown as "A" and "B" respectively) can be mounted in a rack, and
therefore you can use two channels of input and output for each rack.
