Limiter; Lo-Fi Box - Boss BR-1180 Owner's Manual

Limiter

The limiter is an effect that prevents distortion by
suppressing input signals that exceed a set value (threshold).
Effect On/Off
This parameter turns the limiter effect on/off.
Threshold
Adjusts this as appropriate for the inputs signal. When the
input signal level exceeds this threshold level, limiting will
be applied.
Attack
Adjusts the time from when the input level exceeds the
threshold level to when the effect begins to apply.
Release
Adjusts the time from when the signal level drops below the
threshold until when limiting is removed.
Detect HPF
Adjusts the cutoff frequency of the level detection section.
With a setting of Thru, this will operate as a conventional
limiter.
Level
Adjusts the volume.

Lo-Fi Box

Produces a lo-fi sound.
Effect On/Off
This parameter turns the lo-fi box effect on/off.
Effect Type
Select the mode of the lo-fi box.
RADIO:
The sound will appear to be heard from an AM radio.
By adjusting "Tuning," you can simulate the sounds that
occur when you adjust the tuning frequency of the radio.
PLAYER:
The sound will appear to be heard from a gramophone.
The noise caused by scratches and dust on the record are
is simulated.
DIGITAL:
This allows you to create a "lo-fi" sound by lowering the
sample rate and/or decreasing the number of bits.
Realtime modify filters connected in series allow you to
reshape the sound freely.

When "RADIO" or "PLAYER" is selected
Tuning
This is a parameter for "RADIO." It simulates the sounds
that occur when you adjust the tuning frequency of an AM
radio.
Wow Flutter
This is a parameter for "PLAYER." It simulates the wow and
flutter which occur when the speed of the turntable is not
constant.
Noise
This simulates noise.
Filter
Adjusts the filter.
D:E Balance
This adjusts the volume balance of the direct and effect
sounds.
When "DIGITAL" is selected
Pre Filter
This filter decreases digital distortion. When turned off, you
can create an intense lo-fi sound incorporating digital
distortion.
Sample Rate
Modify the sample rate.
Bit
Modify the number of data bits. If this is turned off, the
number of data bits will be unchanged.
If an extremely low number of bits is selected, loud noise
may appear even when there is no sound, depending on the
input source. In such cases, raise the threshold of the noise
suppressor.
Post Filter
This filter decreases the digital distortion produced by lo-fi.
By turning this off, you can create an extremely lo-fi sound.
Effect Level
Adjust the volume of the lo-fi sound.
Direct Level
Adjusts the volume of the direct sound.
