Lo-Fi Box; Effect Type - Boss BR-1200CD Owner's Manual

Release
This adjusts the time it takes for limiting to be removed once the
signal level drops below the threshold.
Detect HPF
Adjusts the cutoff frequency for level detection. When "Thru" is
selected, this will operate as a conventional limiter.
Level
Adjusts the overall volume of the effect.

Lo-Fi Box

This effect is used to produce a lo-fi sound.
On/Off
This parameter turns the lo-fi box effect on or off.

Effect Type

Select the operating mode for the 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.
PLAYER:
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.
■ When "RADIO" or "PLAYER" is selected
Tuning
This parameter is used with the RADIO setting. It simulates the transient
sounds that would occur as you adjust the AM radio's tuning frequency
Wow Flutter
This parameter is used with the PLAYER setting. It simulates the wow
and flutter that occur when the speed of the turntable is not constant.
Noise
This parameter is used to simulate noise.
Filter
This parameter adjusts the filter.
D:E Balance
This adjusts the balance of the direct and effect volumes.
■ When "DIGITAL" is selected
Pre Filter
This filter reduces the amount of digital distortion. When turned off, it
allows you to create an intense lo-fi sound that includes digital distortion.
Sample Rate
This parameter allows you to modify the sampling rate.

Bit
Modifies the number of data bits. When turned off, the number of
data bits will remain unchanged.
If an extremely low number of bits is selected, certain input sources
may result in loud noises being input, even when there is no input
sound. In such a case, raise the noise suppressor's threshold.
Post Filter
This filter reduces the amount of digital distortion produced by the
lo-fi. By turning this off, you can create an extremely lo-fi sound.
Effect Level
Adjusts the overall volume of the lo-fi sound.
Direct Level
Adjusts the volume of the direct sound.
Modify Filter
This parameter selects the filter type.
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 Freq
This parameter adjusts the cutoff frequency.
Resonance
This parameter adjusts the resonance.
Gain
Adjusts the volume level of the sound that has passed through the
modify filter.
