EQ - FLANGER - DDL
EQ-Flanger-DDL combines an EQ with a flanger and a digital delay. Use flanging to get that “jet
aircraft woosh” effect.

EQ
The signal enters an input level trim (parameter 20) followed by a programmable EQ, and then is
routed to the flanger. The flanger is routed directly to the output. The left channel signal passes
through the delay and is routed back into the flanger. Another signal from the delay is routed to
the output on the right side. One feedback parameter (12) controls both delay levels. There are two
discrete echoes that are sent to the left and right outputs respectively. The signal from both echoes
has one level control (parameter 15). There is also an external dry signal (not shown) that goes
directly from the input to the output and is controlled with the mix parameter (01).
01 — Mix
02 — Volume
See the descriptions under the Mix and Volume Parameters, in the beginning of this section. We
recommend a Mix setting of 99.
03 — Flanger LFO Rate Range: 00 to 99
Controls the rate of modulation of the flanger effect.
04 — Flanger LFO Width Range: 00 to 99
Controls the range of the high to low frequency sweep in the flanger effect.
05 — Flanger Center Range: 00 to 99
Controls the sweep center of the flanger effect. The larger the flanger center, the wider will be the
available width.
06 — Flanger Feedback Range: -99 to +99
Controls the amount of feedback applied from the output to the flanger input. The sign of the
value determines the polarity of the feedback.
07 — Flanger Notch Depth Range: -99 to +99
Controls the depth of the notches created by the flanging effect. A setting of +00 will disable the
flanging effect, and also provide a doppler effect for wide, moderately slow LFO rates.
