CELEUS TUBE
INTRODUCTION
Thank you for choosing one of Phonic’s many quality
compact mixers. The CELEUS TUBE compact mixers –
designed by the ingenious engineers that have created
a variety of mixers fantastic in style and performance in
the past – displays similar prociency that previous Phonic
products have shown; with more than a few renements,
of course. The CELEUS TUBE features full gain ranges,
amazingly low distortion levels, and incredibly wide
dynamic ranges, just showing the dominance these small
machines will have on the pro audio market. Unique to
these models is a user-selectable vacuum tube providing
warmth and depth to your main output.
We know how eager you are to get started – getting the
mixer out and hooking all your gear up is probably your
number one priority right now – but before you do, we
strongly urge you to take a look through this manual.
Inside, you will nd important facts and gures on the set
up, use and applications of your brand new mixer. If you do
happen to be one of the many people who atly refuse to
read user manuals, then we just urge you to at least glance
at the Basic Setup section. After glancing at or reading
through the manual (we applaud you if you do read the
entire manual), please store it in a place that is easy for
you to nd, because chances are there’s something you
missed the rst time around.

USB SYSTEM REQUIREMENTS
Windows
• Windows™ XP SP2, Vista™, 7, 8 or 10
• Intel™ Pentium™ 4 processor or better
• 512 MB RAM (1 GB recommended)
Macintosh
• Apple™ Mac™ OSX 10.5 or higher
• G4™ processor or better
• 512 MB RAM (1 GB recommended)
BASIC SETUP
Getting Started
1. Ensure all power is turned o on your mixer. To totally
ensure this, the power supply should not be connected
to the unit.
2. All level controls should be set at the lowest level to
ensure no sound is inadvertently sent through the
outputs when the device is switched on. All levels can be
altered to acceptable degrees after the device is turned
on using the channel setup instructions.
3. Plug any necessary equipment into the CELEUS’ various
outputs. This could include ampliers and speakers,
monitors, signal processors, and/or recording devices.
4. Plug the power cable into the DC inlet on the back of the
mixer and then into a power outlet of a suitable voltage.
5. Turn the power switch on and follow the channel setup
instructions to get the most out of your mixer.
Channel Setup
1. To ensure the correct audio level of the input channel
is selected, each of the level input controls of the mixer
should be turned counterclockwise, or down as far as
they will go.
2. No input other than the one being set should have any
device plugged in. This will ensure the purest signal is
used when setting channels.
3. Select TRANS or TUBE on the TRANS/TUBE switch
located by the main output control. This depends on
which signal you wish to use.
4. Adjust the appropriate output level control (TRANS or
TUBE) to the center position. This will give you a little
wiggle room to play with the overall volume.
5. Set the level control of the channel you are setting to
around the middle point of the control.
6. Ensure the channel has a signal sent to it similar to
the signal that will be sent when in common use. For
example, if the channel is using a microphone, then you
should speak or sing at the same level the performer
normally would during a performance; if a guitar is
plugged into the channel, then the guitar should also
be strummed as it normally would be (and so on). This
ensures levels are completely accurate and avoids
having to reset them later.
7. Set the level controls so the Level Meter indicates the
audio level is around 0 dB. For channel 1, if the incoming
signal is too strong, you can try using the "PAD" button
to lower the level somewhat.
8. This channel is now ready to be used; you can stop
making the audio signal.
9. You can repeat the same process (steps 4 through 8) for
other channels.

USB MODULE STORAGE
The CELEUS USB player module features approximately
70MB of onboard storage to use for playback. That may
sound small but that could mean up to 60 minutes of music
at 128 Kbps, or a few hours of speech at 40 Kbps.
To upload les to the onboard storage, you will need a
USB-A to USB-A cable. Connect the USB connector on
the face of the CELEUS to your computer and it will be
recognized as a USB storage device. Simply copy your
les to the CELEUS TUBE.
Files on onboard storage will only be available when a USB
ash drive is not connected.
AUDIO INTERFACE
By simply connecting the USB cable provided along with
your CELEUS to the device and your personal computer
or laptop, you are able to send DVD quality (16-bit stereo,
with a 48 kHz sampling rate) signal to and from your mixer.
By doing this, you are actually turning your CELEUS
TUBE into a highly useful plug’n’play soundcard for your
computer.
The USB sends an audio stream of the Main Left and Right
(record out) signal of your mixer to the computer. You can
use almost any dedicated Digital Audio Workstation (DAW)
software to record the signal from the CELEUS mixer. You
can also set the mixer as your default audio device.
The USB interface also returns a stereo audio signal from
your computer back to channel 3 of the CELEUS. Ensure
the USB AUDIO button is engaged.

MAKING CONNECTIONS
56
Front Panel
1. Combo Jack
This jack accepts XLR and ¼” phone jack inputs for
balanced and unbalanced signals. They can be used in
conjunction with microphones – such as professional
condenser, dynamic, or ribbon microphones – or line-level
audio devices. With low noise preampliers, these inputs
serve for crystal clear sound replication of microphones.
Note: When using an unbalanced microphone, please ensure phantom
power is switched o. However, when using condenser microphones the
phantom power should be activated.
2. Stereo Channel Inputs
The CELEUS TUBE features 2 stereo input channels
(channels 2 and 3), the inputs of which dier slightly to the
mono channels. Each channel includes two ¼" TRS phone
jacks ideal for use with keyboards, drum machines and
electric guitars.
If you wish to use a mono device on a stereo input, simply
plug the device’s ¼” phone jack into the left (mono) input jack
and leave the right input bare. The signal will be duplicated
to the right due to the miracle of 'jack normalizing'.
Stereo channels can also be used with return signals
from external digital sources. Channel 2 doubles as the
Bluetooth channel, while channel 3 also works with the
USB Audio signal from the computer. When channels are
used for these signals, the stereo input connectors are
eectively disengaged.
3. EFX Output
These 1/4" TS phone jack is the nal output of the EFX mix,
as controlled by the individual EFX rotary controls found
on each channel. This can be used to feed any number of
external signal processors. The signal can then be returned
to the CELEUS TUBE through a stereo line input channel.
4. Output Connectors
These balanced XLR connections will send the nal stereo
line level signal sent from the main mix. These outputs can
be connected to an amplier for sending the signal out to
speakers, or directly to active speakers. These outputs
receive the signals adjusted by the TRANS and TUBE rotary
controls on the front of the mixer. The TRANS control will
adjust the level of the regular transistor audio sent through
the main outputs, while the TUBE control will adjust the
level of the tube signal. The TRANS/TUBE switch located
beside this connector will allow users to determine which
mix the MAIN OUT will send.
5. Tape In (L and R)
These inputs accommodate RCA cables from such devices
as tape, CD and MP3 players. The line from this feed is
directed to the Tape In mix and controlled by the Tape In /
USB Audio level control.
6. Record Out (L and R)
As with the Tape In ports, these outputs will accommodate
RCA cables, able to be fed to a variety of recording
devices. This may include cassette recorders or even
laptop computers. Phonic suggests the use of a y-cable
for connection of consumer electronics that feature mini-
stereo jacks.
The record output has 2 settings: Transistor and Tube. This
allows the record outputs to utilize the CELEUS TUBE's
tube signal or the regular transistor signal, as per your own
needs. The switch to control this setting is found directly
above the RCA Record Output connectors.

smartphone charging cable. Connect the CELEUS to your
smartphone to charge the battery while simultaneously
using the mixer.
9. DC Power Input
This standard DC power input port is for connection of the
included power supply. Please use the included power
supply only as using the incorrect voltage can cause
irreversible damage to the mixer.
10. Headphones Jack
This stereo output port, found on the
very front of the mixer, is suited for use
with headphones, allowing monitoring
of the mix. The audio level of this output
is controlled using the Phones/Control
Room control on the front panel.
CONTROLS AND SETTINGS
11. Phantom Power Switch
When this switch is in the on position, it activates +48V of
phantom power for the XLR microphone input, allowing
condenser microphones to be used on channel 1. Activating
Phantom Power will be accompanied by an illuminated LED
above the mic input. Before turning Phantom Power on, turn
all level controls to a minimum to avoid the possibility of a
ghastly popping sound from the speakers.
NB. Phantom Power should be used in conjunction with balanced
microphones. When Phantom Power is engaged, single ended
(unbalanced) microphones and instruments should not be used
on the Mic inputs. Phantom Power will not cause damage to most
dynamic microphones, however if unsure, the microphone’s user
manual should be consulted.
12. Power Switch
This switch is used to turn the mixer on and o. Ensure you
turn all level controls down before activating. This ensures
no audio is inadvertently sent through your system.

This LED indicator will light up when Phantom Power is
activated on the microphone input.
14. PAD Button
The PAD button is used to attenuate the input signal by 25
dB. This should only be pushed in when using line-level
input devices.
15. Gain Control
This controls the sensitivity of the input signal of the Line/
Microphone input of the rst input channel. The gain should
be adjusted to a level that allows the maximum use of the
audio, while still maintaining the quality of the feed. This
can be accomplished by adjusting it to a level that will allow
the peak indicator occasionally illuminate.
16. Guitar Button
Located on channel 2, this button allows users to adjust the
impedance of the channel so it's appropriate for guitars.
Engaging this button will change the input's impedance to
470KΩ making it ideal for direct connection of guitars.
17. 'BT' and 'USB Player' buttons
Located on channels 2 and 3, these buttons enable their
corresponding channels to be used for their respective
digital audio signals. The BT button allows channel 2 to be
used for the Bluetooth audio streaming function, while the
USB AUDIO button allows channel 3 to control the USB
signal received from the computer through the rear-panel
USB port.

18. Compressor Control and Indicator
This controls the onboard compressor function on channel
1. Turning this control up towards the 12 o’clock position will
adjust the threshold and ratio of the compressor at varying
degrees. Once you reach the 12 o’clock position, the
control will then adjust the compression settings along with
an onboard expander (or, in other words, a compander).
The LED that accompanies this control will light up when
the compressor is triggered.
19. TREBLE (High Frequency) Control
This control is used to give a shelving boost or cut of ±15
dB to high frequency (12 KHz) sounds. This will adjust
the amount of treble included in the audio of the channel,
adding strength and crispness to sounds such as guitars,
cymbals and synthesizers.
20. MID (Middle Frequency) Control
This control is used to provide a peaking style of boost and
cut to the level of middle frequency sounds (2.5 KHz) at a
range of ±15 dB. Changing middle frequencies of an audio
feed can be rather dicult when used in a professional
audio mix, as it is usually more desirable to cut middle
frequency sounds rather than boost them, soothing overly
harsh vocal and instrument sounds in the audio.
21. BASS (Low Frequency) Control
This control is used to give a shelving boost or cut of ±15
dB to low frequency (80 Hz) sounds. This will adjust the
amount of bass included in the audio of the channel, and
bring more warmth and punch to drums and bass guitars.
22. EFX Control
This control alters the signal level that is sent to the EFX
output, which can be used in conjunction with external
signal processors (this signal of which can be returned to
mixer via the stereo return inputs), or simply as additional
auxiliary outputs for any means required. This control also
adjusts the level of audio that is sent to the built-in digital
eect panel.
23. Pan / Balance Controls
This alternates the degree or level of audio that the left
and right side of the main mix should receive. On mono
channels, the PAN control will adjust the level that the
left and right should receive (pan), where as on a stereo
channel, adjusting the BAL control will attenuate the left or
right audio signals accordingly (balance).
24. Peak & Signal Indicators
These LEDs will light up when signals reach certain levels.
The Signal LED on the right will light up when any audio
signal is present on the channel. The indicator on the left
(Peak) will light up when the channel hits high peaks, 6 dB
before overload occurs.
It is best to adjust the channel level control so as to allow
the Peak indicator to light up on regular intervals only. This
will ensure a greater dynamic range of audio.
25. Channel Level Control
This control will alter the signal level that is sent from the
corresponding channel to the main mix.

which will adapt the mixer to
external devices dependeing
on their operating levels. If the input source is -10 dBu
(consumer audio standard), it is best to engage the switch,
giving the signal a slight boost. If the input source is +4

corresponding LED will light up to indicate so.
29. Parameter Control
Turning this control will adjust the one main parameter of
the selected eect. Each eect’s parameter can be found
on the digital eect table.
30. EFX RTN Control
This control adjusts the nal 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 nal level control for the EFX Send mix. Your

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 nal output level of both the
Headphone jack. The default
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 dening 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 nal 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 eectively muted. They will also adjust the nal
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.
