EQUALIZER section

This section sets the internal six-band EQ (HIGH, HIGH MID, MID, LOW MID, LOW, SUB LOW). Of the six bands,
HIGH and SUB LOW EQ can be switched between shelving and peaking types. In addition, the HIGH band can function
as an LPF, and the SUB LOW can function as an HPF.

1 EQ [LPF] switch and LED (HIGH band only)
This switch changes the HIGH band EQ type to LPF.
When LPF is selected, the switch LED will light.
In this case, the [Q]/[GAIN] encoders of the HIGH
band will have no effect, and the perimeter LEDs will
be displayed.
2 EQ [BYPASS] switch and LED
This switch bypasses each EQ band.
When bypassed, the switch LED will light.
3 EQ [ ] switch and LED (HIGH band only)
This switch changes the HIGH band to high-shelv-
ing.
The switch LED will light when high-shelving is
selected.
In this case, the HIGH band [Q] encoder will have
no effect, and the perimeter LEDs will be displayed.
4 EQ [Q] encoder and LEDs
This encoder sets the Q (steepness) of each band.
Rotating it toward the right will make the Q gentler,
and rotating it toward the left will make the Q
sharper.
The range is 10.0–0.10 (41 steps) for each band.
The current approximate value is shown by the
perimeter LEDs.

5 EQ [F] encoder, [VALUE] indicator, and [Hz]/[kHz]
LEDs
This encoder sets the center frequency of each band.
The range is 20 Hz – 20 kHz (121 steps) for each
band.
The current value is shown by the [VALUE] indica-
tor, and either the [Hz] or [kHz] indicators will light
to indicate the units of the displayed value.
6 EQ [GAIN] encoder and LEDs
This encoder sets the gain of each band.
The range is –18 dB – +18 dB (0.5 dB units), and the
approximate value is shown by the perimeter LEDs.
7 [EQ ON] switch
This switch turns the entire equalizer on/off.
The switch LED will light when the EQ is on.
8 EQ [HPF] switch and LED (SUB LOW band only)
This switch changes the SUB LOW band EQ type to
HPF.
The switch LED will light when HPF is selected. In
this case, the [Q]/[GAIN] encoders of the SUB LOW
band will have no function.
