Digital Effect Processor
27. Program Control
This control will allow users to select one of the 16 built-
in digital effects of the CELEUS analog mixer. The effect
names that correspond with the numbers can be found on
the top of the mixer's face, or in the digital effect table.
28. Effects On Button and Indicator
Pushing this button will turn the built-in effect processor
on and off. When the effect processor is activated, the
corresponding LED will light up to indicate so.
29. Parameter Control
Turning this control will adjust the one main parameter of
the selected effect. Each effect's parameter can be found
on the digital effect table.
30. EFX RTN Control
This control adjusts the final output level of the DFX
processor as sent to the main mix. For more EFX in your
signal ('wet'), turn this control up and your channels' level
controls down. For 'dryer' audio, turn the individual channel
level controls up and reduce the EFX control.
31. "To Phones" Button
This button will allow you to send your EFX signal to the
Headphone mix for monitoring.
32. EFX Send Control
This is the final level control for the EFX Send mix. Your
EFX mix is created by using the individual EFX controls
found on input channels 1 through 3.

33. Tape In/USB Audio Control
This control adjusts the incoming signal from both the RCA
"Tape In" jacks and the built-in USB recorder/player. The
signals are then sent to the main mix. If there are input
signals from both the USB interface and the Tape In, the
two signals are combined and controlled simultaneously.
34. Tape In/USB To Phones Button
Pushing this button in will send
your Tape In/USB Play signal to the
Headphone mix for monitoring.
35. Phones Control
This
level
control
determines
the final output level of both the
Headphone
jack.
The
headphones signal is the main
mix unless the "EFX TO MAIN" or
"TAPE IN/USB TO MAIN" buttons
are engaged.
36. Tube Window
The CELEUS TUBE's defining feature is the built-in vacuum
tube. This can be replaced by the user if necessary.
The CELEUS TUBE uses a 12AU7 tube (also known as
ECC82). To replace, unscrew the tube's protective window,
remove it, and carefully take out the existing tube. Ensure
the tube is not hot before handling it.
37. Power Indicator
This indicator illuminates when power is activated.
38. Master TRANS/TUBE Level Controls
These rotary controls are the final level control for the Main
transistor and tube audio mixes, sent to the Main outputs.
When turned all the way up, these Master controls provide
10 dB of gain to the signal, and when set all the way down,
the signal is effectively muted. They will also adjust the final
output level of the signal sent through the USB interface to
the computer.
39. TRANS/TUBE to Headphones Button
This button determines whether the Transistor or Tube
signal will be sent to the headphone output. Essentially, it
allows users to better monitor and compare the two signals
before determining which they prefer to use.
40. Level Meter
This dual 41 segment level meter gives an accurate indication
of when audio levels of the Main L/R signal reach certain
levels. The 0 dB indicator illuminates is approximately equal to
an output level of +4 dBu (balanced), and the PEAK indicator
illuminates about 1.5 dB before the signal is dynamically
clipped. To make the maximum use of audio, set the various
level controls so that it sits steadily around 0 dB to make full
use of audio, while still maintaining fantastic clarity.
