5Creon
Welcome
and thank you for purchasing the Creon. It combines a high-performance USB audio
interface with high-quality preamps and a separate, fully-featured analog monitor controller. You can play and play back, record and convert, control and listen with one
single device. So all you essentially need for a truly professional recording setup is the
Creon and a DAW.
Introduction
With and without DAW
Creon is designed to operate with your Digital Audio Workstation. But you can also do
a lot with it as a stand-alone device: plug in an instrument and play. Connect a microphone and sing along. Mix your own monitor signal with playback or guide tracks from
any source. What you are playing is not bad? Turn on the DAW and record it.

Placement
Place the unit on a leveled and stable surface or mount it in a dedicated rack frame.
The unit’s enclosure is EMC-safe and effectively shielded against HF interference.
Nonetheless, you should carefully consider where you place the unit to avoid electrical
disturbances. It should be positioned so that you can easily reach it, read the meters
and status LED‘s well, but there are other considerations as well. Try not to place it
near heat sources or in direct sunlight, and avoid exposure to vibrations, dust, heat,
cold or moisture.

USB
Connect here your computer. Alternatively you can connect an iPad or iPhone with the
original Apple camera adapter. The USB port complies with the Hi-Speed USB 2.0 specification with a data transfer rate of 480 MBit/s, and is Apple Class 2 compliant as
well.
USB 3 is backward compatible with USB 2, which means that the Creon can also be
connected to any USB 3 port. The Hi-Speed USB 2 specification is enough to provide
the Creon with the necessary data throughput. We decided to use the USB 2 interface
Connections
due to the reliability of the drivers..
The package includes an appropriate USB cable.
In case you use a different cable, make sure it complies to the Hi-Speed USB 2 specification. It recommends a maximum length of five meters. We recommend to keep the
cables as short as possible, remember: the shorter, the better. For cable runs extending over five meters, you could use a hub or a line extender, in which case you should
get the advice of an expert.

Connections
Sources 1 and 2
You have two stereo source inputs with different connectors at your disposal: Source
input 1 via two mono jacks (balanced), Source input 2 via two RCA connectors.
This means you can connect two audio devices as playback sources, be it a CD or MP3
player, a tape machine or even a smartphone.
Typical applications include the use of reference tracks to do A/B comparisons or playing an instrument on top of a song while listening to it — everything without the need
to connect the Creon to a computer.
IMPORTANT:
The source inputs are conventional playback
channels. Their signal cannot be recorded with
a DAW.

Input Selection:
Connections
Microphone-, Instrument- und Line Inputs
Taking into account both microphone inputs, the instrument and four line inputs, you
have five analog inputs at your disposal. Two of the five inputs can be used simultaneously for recording purposes.
The selection is defined by the assignment of the corresponding inputs. This has the
added advantage that the channel configuration can be directly and intuitively made
out by the assignment of the connections, plus there is almost no need for switching.
The input selection follows this provision:
Line 1|2 has preference over Mic Input 1|2
Instrument input has preference over Mic input 2 and Line input 2
IMPORTANT:
To record microphone signals, Line 1 and/
or Line 2, Instrument ought to be free. If you
cannot hear a microphone signal, check
whether Line 1, Line 2 or Instrument input are
free or not.

Mic Inputs
You can connect dynamic, condenser, tube, and ribbon microphones to the mic inputs.
Use the Phantom switch to provide phantom power to the microphones that require it.

Phones
Use the Phones jack on the front panel to connect your headphones. You can connect
all types of headphones with impedances from 20 to 600 Ohm. This wide range entails
big volume differences between low- and high-impedance headphones. In order to
keep under control low impedance headphones, we set a comparatively high impedance of 33 Ohms at the output.

phone preamp, for example to change headphones. This way you will avoid loud crackling noises reaching your ears. Plus, it will also spare you unexpected surprises whe-
never the new headphones you connect have a lower impedance or a higher efciency,
which will make them sound louder when connected to the Creon and keeping the
same volume setting.
Never connect mono plugs to the stereo jacks on the front panel. Otherwise you can
cause a short circuit that will damage the amplier! Headphone cables always have
stereo plugs.

Unbalanced Connections
XLR/Stereo Jack to Mono Plug/RCA
Connections
Unbalanced connections are also possible without the need of an adapter. It is important to verify the polarity of the three balanced wires. The image shows the pinout
of the XLR connectors, as well as the correct polarity for connections with unbalanced cables, whereby Pin 1 and 3 ought to be connected (for the stereo plug: ring and
ground). We recommend the use of specially manufactured 1/4“ stereo jack/XLR to
1/4“ mono plug/RCA cables to avoid the use of adapters. Such cables can be found in
specialized shops. The pinout diagram will help the specialist dealer make sure he provides you with correctly configured cables.

Mic Gain
The Creon features two identical microphone preamps. The preamps are discrete,
which means they use single transistors instead of ICs. This allows the preamp to be
perfectly optimized for its task — such efforts are usually taken only in the production
of high-end preamps.
Use the Mic Gain control to adjust the microphone preamp level. The adjustable
volume range spans from +3 to +60dB. To achieve the best recording level, the -6dB
LED should flash from time to time: you have enough headroom left. If the LED remains
always on, it means that the level is at the brink of overloading — in such cases, you
Control Elements
should reduce the Mic Gain value.
The OVL LED indicates the Creon‘s converter is overloading, which should be strictly
avoided.
IMPORTANT:
Line 1|2 has preference over Mic Input 1|2
Instrument input has preference over Mic input 2 and Line input 2
To record microphone signals, Line 1 and/
or Line 2, Instrument ought to be free.
If you cannot hear a microphone signal,
check whether Line 1, Line 2 or Instrument
input are free or not.
Content
27Creon
48 V
Use the 48V switch above the Mic Gain knob to activate the 48 Volt phantom power
to supply condenser microphones with an integrated preamp. To work correctly such
microphones require a clean, noiseless voltage, which the Creon can provide.
IMPORTANT:
First connect the microphone to the Creon and then engage the phantom power. Now
you can start to work. Once you are done, disengage the phantom power first. Wait at
Control Elements
least ten seconds after disengaging the 48 V phantom power, before you disconnect
the microphone from the Creon, to allow for complete discharging — otherwise you
could damage the Creon‘s input stages.
VERY IMPORTANT:
All condenser microphones with a balanced, oating output, as well as ribbon
microphones, can be used with phantom
power. A microphone with an unbalanced
output should only be used without phantom power! We recommend you to disengage the phantom power for all types of
microphones except condenser micropho-
nes .

High-Pass Filter
The high-pass filter passes high-frequency signals but filters out impact noise, rumble
and other unwanted noises below 75 Hz. This first order filter has a 6dB/octave slope,
which means it is soft and goes unnoticed acoustically speaking.
Besides impact noise, other unwanted noises include the ones produced when handling the microphone.
Application examples:
Control Elements
Stage miking, speech recordings, vocals and high-pitched instruments where you are
sure that you will not need to record lower-pitched neighboring instruments.
Another aspect you should consider: low frequencies require a lot of energy during
conversion, which is another argument for engaging the high-pass filter when the
recording allows for it.
Content
29Creon
Instr Gain
The Creon also includes an instrument preamp. Use the Instr Gain control to adjust
the instrument preamp level in steps. The adjustable volume range spans from -6 to
+31dB. The possibility to reduce the level -6dB allows for the direct connection of electric bass guitars. To achieve the best recording level, the -6dB LED should flash from
time to time: you have enough headroom left. If the LED remains always on, it means
that the level is at the brink of overloading — in such cases, you should reduce the Instr
Gain value. The OVL LED indicates the Creon‘s converter is overloading, which should
be strictly avoided.

LED Indicators
The central LED display panel provides information about the operating status and
also helps you adjust better microphone and instrument signals.
Level Adjustment with two LED sets
Two traffic-light-like LED sets indicate the level of the four recording channels. Every
set of LEDs is numbered: set 1 correspond to mic preamp 1 and set 2 correspond to
mic preamp 2 and the instrument preamp.
Control Elements
Each LED set is identical to the others:
The OVL LED lights red to indicate the Creon‘s converter is being overloaded
The -6 (dB fs) LED lights yellow. An optimally adjusted level makes it flicker on and off
from time to time
The SIG LED lights green and indicates the presence of a signal
OVL > +15 dBu ( Host LED on)
> +20 dBu ( Host LED off)
-6 > +9 dBu
SIG > -20 dBu
Content
31Creon
Special note regarding the OVL LED:
this LED is directly connected to the converter and thus indicates the overloading of
the converter. Make sure it never lights during a recording, otherwise you risk ending
up with a useless take due to the presence of audible distortion. As a safety measure,
the OVL LED remains lit for around a second.
Status LEDs
Control Elements
The PWR LED indicates the power supply of the unit.
The HOST LED indicates that a host computer has been detected at the USB port and
the connection has been correctly established.
Note:
When used standalone, without DAW or iPad connected to the USB port, the digital
section is not initialized. And since the OVL LED is controlled directly by the converter,
if not initialized, the OVL LED is inactive.
Content
32Creon
Analog Inputs
The Creon allows the simultaneous recording of two analog inputs.
Switch 1|2 engaged: you hear Mic or Line inputs 1 and 2.
When recording a mono vocal track it makes sense to hear it in the center of the stereo
image, so you should engage the Mono switch as well.
DAW Returns
Control Elements
The Creon has two DA converters that allow you to monitor a stereo signal (two chan-
nels) from the DAW.
Switch 1|2 engaged: you hear the Mix from DAW outputs 1/2.
Content
33Creon
Sources
As a true monitor controller, you can also use the Creon as a preamp for two stereo
sources. Use the two switches under Sources to manage the two source inputs, which
are named after their connector format. For more information on the connectors refer
to „Sources 1 and 2“ on page 16.
JACK = balanced 1/4“ input (for a professional CD player or a converter, for example)
RCA= unbalanced RCA input (Hi-Fi CD player, AV receiver or similar)
Control Elements
Note: the level of both unbalanced inputs is automatically converted to professional
level in order for them to be directly comparable according to the Creon‘s standard
level.
Speaker DIM
The DIM switch reduces the monitoring level -20dB.

Monitor Mix
With the Monitor Mix control you create a monitor mix fast and easily. No need to fi
ddle with gain controls or faders, just blend between the Inputs (mic, line, instrument)
and the DAW/Sources.
The analog monitoring of all analog inputs and sources is absolutely latency-free, it is
as real-time as it gets.
Control Elements
In the center position (1:1), the volume of the analog inputs (mic, line, instrument) and
DAW returns and sources is balanced. When set hard left, you can only hear the analog
inputs (mic, line, instrument). Hard right you can only hear the DAW returns and sources through your monitoring system.
Content
35Creon
Phones
The Creon features a powerful headphone amplier. Use the Phones volume control to
adjust the level of the headphones signal.
Headphones volume adjustment is also independent from that of the loudspeakers.
The outputs and gain are designed for headphones with impedances from 20-600
Ohms. For more details regarding the connection of headphones, refer to „Headphone
Outputs“ on page 23.
Control Elements
Optimal Potentiometer Control Range
The control range of the headphone amplifiers is very wide: it allows you to listen to
very high level signals with 30 Ohm headphones, as well as to detect the faintest
details in quiet passages with 600 Ohm headphones. To achieve such a wide range,
and due to component characteristics, a constant taper during the beginning of the
travel of the potentiometer cannot be guaranteed. A reduction of the overall volume
would also lower the tolerance in this initial range, but at the price of wasting power
margin. Thus, we recommend you to adjust the level above the „1“ mark to achieve the
best results.
Content
36Creon
Volume
Use the Volume potentiometer to adjust the volume of both channels of the
Speaker | Main Out outputs on the rear panel. The high-grade potentiometer regulates
the audio signal directly to avoid any coloration/distortion typical of VCAs and DCAs,
which require higher inter-channel tolerances and have a tendency towards higher distortion figures. The Volume control uses a relative dB scale referenced to the input
level. When set to the 0dB mark the input level is „as is“ (the amplification factor is 1
or unity gain).
The signal can be attenuated up to -78dB.
Control Elements
If the signal can still be heard when hard left, do not worry: the potentiometer is not a
switch. This was a conscious decision we made to be able to offer you an amplification
possibility too. Power off the source when you want to mute it.
Recommendation: Calibrate the whole monitoring system (read the following section)
so that the control range in use is always between eight and two o‘clock of the travel.
This is the range where the potentiometer works best, which guarantees a good and
noiseless level matching for the monitoring system.
Content
37Creon
Calibration of the Monitoring System
Calibration of the Monitoring System (Part 1)
The input signal level of the Creon and the input sensitivity of the power amps or
active speakers should be matched to ensure a proper overall gain. An inappropriate
matching results, for example, in an extremely high monitoring level with a fairly low
volume setting (at 9 o‘clock). Likewise, settings above two o‘clock should sound really
loud, otherwise it is indicative of a matching problem.
During calibration it can get very loud and annoying, so don‘t forget to wear ear
protection.
For calibration we recommend using a SPL Meter (where SPL stands for „Sound
Pressure Level“). Place the measuring microphone at the listening position and playback pink noise from a generator calibrated to 0dBu. Each measurement should be
done with one channel (and loudspeaker) at a time. 83dB SPL at the listening position
is a good and very common reference value.
Content
38Creon
Calibration of the Monitoring System
Calibration of the Monitoring System (Part 2)
Adjust the volume control until the SPL meter reaches 83dB with pink noise.
Ideally, 83dB SPL should be reached when the volume control is near the 12 o‘clock
mark.
Write down the exact value for 83dB SPL at the listening position. If it only reaches
83dB SPL above two o‘clock, increase the power amps‘ or active loudspeakers‘ input
sensitivity (higher dB value).
Conversely, you should decrease the power amps‘ or active loudspeakers‘ input sensitivity (lower dB value) when it indicates 83dB SPL before reaching the 12 o‘clock mark.
