6.3 Post-amp effects
The post-amp effects described in the following paragraphs
are located post amp and cabinet simulations in the signal chain.
An integrated crossover determines at what frequency the
effects start working and regulates the bass information when
the unit is used without effects. The cut-off frequency of this
18 dB/octave Butterworth crossover is regulated in EDIT mode
under X-OVER. The display shows the frequency divided by
factor 10. Adjustments are made by using the bank UP/DOWN
keys. If the display shows “-”, the crossover is not activated and
the complete signal is affected by the effects. When, for example,
“8” is shown in the display, this means that frequencies under
80 Hz remain unaffected by the effects.
Volume balance between the high pass and the low pass can
be adjusted when you are setting up the crossover settings by
using the EFFECTS control (all the way to the left = low pass
signal only, all the way to the right = high pass signal only).
6.3.1 Reverb and delay algorithms
DELAY+CHORUS: This algorithm combines a delay and the
ever-popular chorus effect.
ST. DELAY: A delay of the input signal. Different tempo settings
enable you to produce interesting delay effects. This way, you
can quickly create repititions—particularly with “slapping”—that
wouldn’t even be possible without a delay.
DELAY/LOOP: This function allows you to jam along with your
own signal. To do that, record with the delay/loop effect a short
sequence (max. 15.36 sec.). This sequence can be played back
in an endless loop.
6. EFFECTS PROCESSOR
You can for example use this loop as a foundation for your
melody and improvise around it. To record this sequence via
MIDI, send the respective MIDI controller (see chapter 10 ). When
you use this function without MIDI, the delay can last a maximum
of 1023 msecs.
REVERB: The reverb is still the most important effect in a
mixdown or during a live event. A reverb is used to add ambience
to an otherwise “dry” sound.
AMBIENCE: This effect simulates a room without reflexions.
6.3.2 Modulation effects
PHASER: The phaser functions according to the principle that
a second, phase-shifted signal is added to the original signal.
This way, the signal seems thicker and livelier. This effect was
originally used for guitar sounds and keyboards. In the ’70s, it
started being used for other instruments as well (e. g. electric
piano and electric bass).
FLANGER: A flanger modulates the tone pitch of a signal
upwards and downwards at a constant tempo.
(STEREO) CHORUS: This effect subtly detunes the original
signal. This way, a pleasant effect is created in combination
with a tone pitch variation. This effect is particularly well-suited
to lend a warm characteristic to the bass sound. Additionally,
when “popping” occurs, it can make the tone sound less intrusive
and harsh.
6.3.3 Special effects
VCF+FLANGER: The combination of filter and flanger effect.
VOICE BOX: This vocal simulation fades between various
vowels (a/e, a/i, a/o etc.) by using a LFO (Low-Frequency
Oscillator). You can control this effect via a MIDI foot controller.
ULTRABASS: A very low bass sound that lies an entire octave
beneath the lowest bass frequency present in the mix is currently
very popular. However, this sound can often only be created at
the studio because most bass amplifiers have no subharmonic
function. The ULTRABASS processor, which has also found
home in various BEHRINGER bass amps, makes creating this
effect a no-brainer. You will be amazed how ultra-low the sounds
created with the ULTRABASS function are.
