Rocktron Xpression, User Manual

Page: 28 / 76

Delay provides a reproduction of the input signal, occurring at a prescribed
time (usually expressed in milliseconds) following the input signal. The
Xpression provides two discrete delays (Delay 1 and Delay 2), each of which
has its own set of parameters to determine its particular characteristics.
The PARAMETER SELECT control will allow you to access each of the following
Delay parameters:
The PARAMETER ADJUST control allows you to adjust the selected parameter:

The DELAY I/O parameter determines whether the delay circuit is
active or bypassed for the current preset. Select IN to active the delay.
Select OUT to bypass the delay.
The MUTE TYPE parameter allows for muting the delay at its input
(PRE), its output (POST) or BOTH.
Muting the input (PRE) of the delay will not allow any signal to enter
the delay section until the delay is switched in. When using a moderate
amount of regeneration, switching out the delay with the input muted
will allow you to generate a non-delayed signal which will play over
the decaying regenerated signal which continues on after the delay is
switched out.
Muting the output (POST) of the delay will result in the delayed signal
being immediately turned off when the delay is switched out. This
means that delays and regeneration will not continue when the delay is
switched out. If the output were not muted, signals that were input
before the delay was switched out would be allowed to regenerate,
even after switching out the delay.
It is also possible to mute both the input and the output (BOTH) so that
no signal enters or exits the Delay section until it is switched in.
The TIME1 parameter determines the multiplier by which a new delay
time will be selected for Delay Time 1 when the Tap Delay feature of
the Xpression is used. (See Section 7 page 50: "Tap Delay" for more
information on the Tap Delay feature.)
The TIME2 parameter determines the multiplier by which a new delay
time will be selected for Delay Time 2 when the Tap Delay feature of
the Xpression is used. (See Section 7 page 50: "Tap Delay" for more
information on the Tap Delay feature.)
The DELAY LEVEL parameter determines the overall level of the
delayed signal at the output of the Xpression.
The D-MIX S1/S2 parameter defines the ratio of Source 1 signal to
Source 2 signal to be input to the Delay section. Source 1 is the Voice 1
output from the previous effect in the signal chain (chorus, flanger,
pitch shifter, etc.), while Source 2 may be the Voice 2 output from the
previous effect in the signal chain or the direct signal (selectable via the
SOURCE 2 parameter). (Refer to the block diagrams shown on pages
17 and 18 for a visual representation of the input to the Delay section.)
