6.7 EQ
In the input state, press once to switch to PEQ and press twice to switch to GEQ.
IN_1: MENU:EQ
EQ#: 1
BYP: O
FRQ: 0100000HZ
TYP: PEQ
BW : 0.33
Q=4.36
LVL : 0.00dB
IN_1: MENU:GEQ
GEQ# : 1
LEVEL : 0.00dB
(f=20Hz)
BYPASS: O
EQ#:
Each input channel has 8 bands of equalization. This control selects one of
the 8 available bands.
BYP:
This control will un-bypass (Off) or bypass (On) the currently selected band.
TYP:
The 5 types of EQ that can be used are: parametric (PEQ), low shelf (LOSHF),
high shelf (HI-SHF), 1st degree all-pass (AP-1), and 2nd degree allpass (AP-2).
FRQ:
The EQ center frequency ranges from 20Hz to 30kHz in either 1Hz steps or 1/36 octave
steps.
BW:
The EQ bandwidth ranges from 0.02 to 3.61 octaves in steps of 0.01 octave.
The equivalent Q value is automatically shown besides the octave value.
For 1st degree all-pass (AP-1) filter, the bandwidth will sets the phase shift at the
centre frequency. This phase shift is gradually changed from 180 degrees above
the centre frequency to the specied value.
LVL:
The EQ level (or gain) ranges from -30.00dB to +15.00dB in 0.25dB steps.
GEQ#:
The graphic equalizer has 31 bands of equalization from 20Hz to 20kHz. This control
selects one of the 31 available bands. The frequency corresponding to each band is
also shown.
LEVEL:
The GEQ level (or gain) ranges from -30.00dB to +15.00dB in 0.25dB steps.
BYPASS:
This control will un-bypass (Off) or bypass (On) the entire GEQ for this channel.
