Graphic Equalizer; Lfo Filter; Auto Filter; Lofi - Behringer DDX3216 Operating Manual

Bass-Level (0 to 100%)
The Bass-Level parameter defines the intensity of the
harmonics generated for the low frequency range.
NR-Response (20 to 400 ms)
This parameter controls the response time of the gate.
NR-Threshold (-90 to 0 dB)
Use the NR-Threshold parameter to adjust the threshold below
which the gate is activated.

5.2.22 Graphic Equalizer

The Graphic Equalizer algorithm offers eight frequency bands,
each with a maximum boost/cut of 15 dB. The following
frequencies are available for processing: 50 Hz, 100 Hz, 250 Hz,
500 Hz, 1.5 kHz, 3.5 kHz, 7 kHz and 14 kHz. As this effect is
actually an insert effect, we recommend that you route the effect
post-fader, but disable the channel's main routing. In this way,
only the processed signal will be audible via the FX return path.

5.2.23 LFO Filter

The LFO (low-frequency oscillator) provides three different
operating modes: low pass, high pass and band pass. The low-
pass filter allows low frequencies to pass, but suppresses high
frequency signals. The high-pass filter allows high frequencies
to pass, but suppresses low frequency signals. The band-pass
filter leaves an adjustable frequency range unprocessed, but
suppresses all frequencies above and below that range. As this
effect is actually an insert effect, we recommend that you route
the effect post-fader, but disable the channel's main routing. In
this way, only the processed signal will be audible via the FX
return path.
Fig. 5.24: Parameters of LFO Filter algorithm
Speed (0.05 to 40 Hz)
This parameter adjusts the LFO frequency, i. e. the speed of
the filter modulation.
Wave (Tri, Sin or Squ)
The Wave parameter controls the shape of the modulating
waveform (triangle, sine or square).
Slewing (1 to 50 ms)
This parameter is available only for the SQU wave and allows
you to smooth sharp edges of the square wave.
Base Frequency (100 Hz to 10 kHz)
This parameter defines the cutoff frequency of the filter.
Filter-Mode (LP, HP or BP)
Use this parameter to determine the type of the LFO filter.
Available types are: LP (Low Pass), HP (High Pass) or BP
(Bandpass).
Depth (0 to 100%)
The Depth parameter controls the modulation depth of the filter.
Filter-Q (1 to 20)
This parameter controls the filter resonance and allows you to
accentuate the frequencies close to the cutoff frequency.

The Auto Filter algorithm is quite similar to the LFO Filter, but
depends on the level of the signal to be processed. As this effect
is actually an insert effect, we recommend that you route the effect
post-fader, but disable the channel's main routing. In this way, only
the processed signal will be audible via the FX return path.
Fig. 5.25: Parameters of Auto Filter algorithm
Base Frequency (100 Hz to 10 kHz)
This parameter defines the cutoff frequency of the filter.
Filter-Mode (LP, HP or BP)
Use this parameter to determine the type of the Auto Filter: LP
(Low Pass), HP (High Pass) or BP (Band Pass).
Sensitivity (0 to 100%)
This parameter defines the filter sensitivity, i. e. the threshold
above which the filter opens.
Filter-Q (1 to 20)
This parameter controls the filter resonance and allows you to
accentuate the frequencies close to the cutoff frequency.
Attack (10 to 1,000 ms)
Defines the time until the filter opens.
Release (10 to 1,000 ms)
Defines the time during which the filter closes.
For years and years, digital engineering has been trying to
achieve high-quality, low-noise and ever more brilliant audio, but
a "back to the roots" trend in the recent past has made more and
more people rediscover the warmth of analog sounds. The techno
and dance community loves vinyl and many a music lover misses
the charm of the good ol' LPs and tapes. The latest trend is called
"lo-fi"—instead of "hi-fi". To take account of this trend we offer
you this "weird" effect algorithm. Your recordings will definitely
have an "8-bit" sound as well as the same noise floor as a real
vinyl record—like in the good ol' days! As this effect is actually
an insert effect, we recommend that you route the effect post-
fader, but disable the channel's main routing. In this way, only
the processed signal will be audible via the FX return path.
Bits (6 to 16)
The Bits parameter reduces the quality of the audio signal to
the adjusted resolution.
Signal-HP (20 Hz to 16 kHz)
The Signal-HP parameter adjusts the cutoff frequency of the
high-pass filter.
Noise-Gain (0 to 100%)
This parameter determines the volume of the noise generated.
Signal-LP (100 Hz to 20 kHz)
The Signal-LP parameter adjusts the cutoff frequency of the
low-pass filter.
Noise-HP (20 Hz to 16 kHz)
This parameter adjusts the cutoff frequency of a high-pass
filter, which is effective exclusively on the noise generated by
the LoFi algorithm.
