LOW CUT
Parameter/
Range
Explanation
ON/OFF
OFF, ON Turns the LOW CUT effect on/off.
DEPTH
20 –2000 Hz
This parameter sets the frequency below
which vocal pop and other undesirable
lower-range noises will be filtered out.
LO-FI
Parameter/
Range
Explanation
ON/OFF
OFF, ON Turns the LO-FI effect on/off.
TYPE
Select the type of lo-fi box.
RADIO
The audio will sound as if it is being played
on an AM radio.
By adjusting “TUNING,” you can simulate
the transient sounds that would occur as
you adjust the radio’s tuning frequency.
VINYL
The audio will sound as if it is being played
on a gramophone.
Needle noise caused by scratches and dust
on the record is also simulated.
DIGITAL
This setting allows you to create a lo-fi
sound by lowering the sample rate and/or
decreasing the number of bits.
A bank of series-connected real-time modify
filters allow the sound to be freely reshaped.
TUNING *1
0–100
This parameter is used with the RADIO set-
ting.
It simulates the transient sounds that would
occur as you adjust the AM radio’s tuning
frequency.
WOW FLUTTER *2
0–100
This parameter is used with the VINYL set-
ting.
It simulates the wow and flutter that occur
when the speed of the turntable is not con-
stant.
NOISE *3
0–100 This parameter is used to simulate noise.
FILTER *3
0–100 This parameter adjusts the filter.
D:E *3
100:0–0:100
This adjusts the balance of the direct and ef-
fect volumes.
PRE FILTER *4
OFF, ON
This filter reduces the amount of digital dis-
tortion. When turned off, it allows you to
create an intense lo-fi sound that includes
digital distortion.
SAMPLE RATE *4
OFF,
1/2–1/32 This parameter allows you to modify the
sampling rate.
BIT *4
OFF, 15–1
Modifies the number of data bits. When
turned off, the number of data bits will re-
main unchanged.
If an extremely low number of bits is select-
ed, certain input sources may result in loud
noises being input, even when there is no in-
put sound. In such a case, raise the noise
suppressor’s threshold.
POST FILTER *4
OFF, ON
This filter reduces the amount of digital dis-
tortion produced by the lo-fi. By turning this
off, you can create an extremely lo-fi sound.
E.LEVEL (Effect Level) *4
0–100
Adjusts the overall volume of the lo-fi
sound.
D.LEVEL (Direct Level) *4
0–100 Adjusts the volume of the direct sound.
MODIFY FIL (Modify Filter) *4
Select the effect of modify filter.
OFF No modify filter will be used.
LPF A low-pass filter will be used.
BPF A band-pass filter will be used.
HPF A high-pass filter will be used.
CUTOFF F *4
0–100 This parameter adjusts the cutoff frequency.
RESONANCE *4
0–100 This parameter adjusts the resonance.
GAIN *4
0– +24 dB
Adjusts the volume level of the sound that
has passed through the modify filter.
