TERMINOLOGY
The term Delay Line refers only to the Bucket Brigade Devices (BBDs) and
analog signal processing between the input and output stages. Delay and
Analog Delay refer to the entire 500 Series Module.
GAIN STAGING
Unlike digital delays, pushing the Analog Delay into overdrive is a very
musically useful effect. When the
LEVEL LED flashes ORANGE, built-in
limiters are activated. Beyond this point, higher DRIVE settings will result
in gentle saturation and increasing harmonic content added to the signal.
RED flashes indicate clipping. We encourage you to experiment with differ-
ent
DRIVE settings and their effect on multiple sound sources.
NOTE: For many audio interfaces, a DRIVE setting for unity gain will be
between 2 and 4, with an OUTPUT setting between 6 and 8. DELAY TIME
and FEEDBACK settings also affect the output level from the Delay Line.
Increasing FEEDBACK increases the output level due to the cumulative ef-
fect of sending output signals back into the BBDs. Decreasing the DELAY
TIME decreases the output level via shorter voltage charge and discharge
rate of the capacitance sections in the BBDs.
FREQUENCY RESPONSE AND LEVELS
The Analog Delay was designed with an area of filter overlap in the 0.5x
(Short) and 1.0x (Long) delay ranges, with the 0.5x range (35ms-400ms)
having a broader frequency response. This provides the ability to fine tune
the tonal characteristics of the delayed sound.
age charge and discharge rate of the capacitance sections in the BBDs.
CONTROLS, INDICATORS, AND INPUTS
The Analog Delay has been designed with a combination of physical and
virtual controls for modern studio and live sound workflow. Primary con-
trols for the Delay Line are located on the Delay’s front panel.
The 6-waveshape LFO is controlled by the free plugin/stand-alone editor
or via MIDI messages. There are no LFO controls on the front panel.
NOTE: Upon launching the editor for the first time you will be prompted to
set the MIDI port for the Analog Delay.
