Installing the C03U
Installing the C03U is a simple procedure that takes just a few minutes. Since the
C03U is USB compliant, you can use either a MAC or PC, connect the included USB
cable and plug and play. You will be able to control your C03U using the standard
audio interface controls in the MAC or Windows operating system. You will find
detailed instructions on setting up with MAC OS and Windows in the following sec-
ENGLISH
tions of this manual.
For expanded control, you can install the Samson Softpre applet which will give you
programmable Gain and a digital Input Meter so you can adjust the internal, digitally
controlled microphone pre-amplifier to the correct level. You can also use the Low Cut
Filter to remove unwanted low frequency rumble. There's even a Phase switch so you
can invert the signal polarity when using multiple microphones.
Since it is possible to adjust the level of the signal from the operating system preferences, and in your recording software, it's a good idea to be familiar with these controls in the MAC or Windows operating system. Therefore, we recommend that you
follow the section Getting Started with Windows XP (and 98) or Getting Started with
MAX OS X before installing the C03U software driver.
IMPORTANT NOTE:
program, so we recommend that you install the microphone on your computer without
the Softpre first. Then, please check our website for a list of programs that work with the
Softpre applet.

Using the Softpre Software Applet
Installing the Softpre Software
The C03U can work with most audio software by
simply connecting the microphone to your computer
using the supplied USB cable. However, to take advantage of the advance features you should install the
Samson C03U software. Getting the software is easy.
Just type samsontech.com into your favorite internet
browser, look for the C03U driver link and follow the
on screen instructions to download the driver. After
you download the driver software, run the installation
program and start to use the C03U software.
Once you have the C03U software installed you can
operate your C03U by following the simple instructions outlined in the following sections of this manual.
Setting a Good Level
One of the most important fundamentals of good
audio engineering is setting proper levels. Even on a
small typical mixer, or basic multi-track recorder, there
are several controls that affect the level of a signal as it
makes it’s way from your sound source to your speakers and then, ultimately, the level of your headphone
or monitor system. These include pre-amp gain, EQ,
aux sends and returns, channel fader level, bus or group levels, and finally, the master
fader. That’s not to mention the level of the 5:15 train on its way to Pennsylvania
Station who’s thunderous crossing horn can be picked up from 5 miles away while
miking a nylon string guitar, despite the use of double moving blankets over the windows of your project studio. But that’s another story with another set of disciplines.
Start off by being aware that anytime you change any control in the audio path, you
are probably affecting gain somewhere. Then, be sure to carefully monitor the levels
on your input and output meters to avoid a clipped signal with too many peaks.
Also, remember your ear is the most sophisticated and calibrated piece of test gear
you have. So, setting a good level should be approached from a technical point of
view, and then confirmed, by a creative point of view.
ENGLISH
INPUT GAIN – Fader
The C03U has an onboard, digitally controlled analog INPUT GAIN stage which is
controlled by the C03U software fader. The fader control provides a range of gain
from -62 to +48 dB. The C03U can accept levels from most any sound source by using
the INPUT GAIN fader. You can use the INPUT GAIN control to adjust the level of your
input signal. It is a good idea to start with the level low and raise it up as you need.
Be sure to monitor the input digital VU METER and try to set the INPUT GAIN control
so that the meter reads just below the CLIP indicator. If you see the CLIP indicator
light you are “Over–Loading” and the sound may become distorted. If this happens,
simply back down on the INPUT GAIN Fader. The CLIP indicator will stay red until you
clear it by clicking on the CLIP icon.
5
Using the Softpre Software Applet
DIGITAL VU METER - Input Level
To monitor the signal being sent from the
C03U, there is an digital VU METER with a scale
from infinity to Digtal Mximum or CLIP. The
level displayed on the meter will be affected by
the Input Gain Fader so be sure that you have
that set to the correct position for your sound
ENGLISH
source. The digital VU METER features “VU”
ballistics, which means it reacts to the signal
based on an average level. Use the VU METER
when you are setting your input level using
the GAIN control. Try to set the level so that
the meter reads about just below CLIP but so
that it never goes to CLIP. If you see the CLIP
indicator light you are “Over–Loading” and the
sound may become distorted. If this happens,
simply back down on the INPUT GAIN Fader.
The CLIP indicator will stay red until you clear
it by clicking on the CLIP icon.
Using the Low Cut Filter
Like any good mic pre, the C03U software
features a Low Cut, (or High Pass), filter for
attenuating the bottom-end frequencies. The
Low Cut filter allows you to remove the lower
frequencies that you sometimes just don’t wantto pick up. For example, when you
are miking a high-hat you only want to capture the frequencies that the hi-hat is producing. Therefore, by using the Low Cut filter, you can reduce the amount of pick-up
from the low toms and bass drum that may leak into the hi-hat mic. You can use the
same technique on other instruments like acoustic guitar, violin, piano and even on
vocals. In live sound applications, the Low Cut filter is especially useful for removing stage rumble. The Softpre software provides a variable Low Cut filter that allows
you to adjust the exact frequency at which the low frequencies begin to roll-off, or
attenuate.
PHASE – Switch
For a variety of miking and mixing techniques, it may be necessary to invert the signal phase from the source you have plugged into your C03U and Softpre software.
When the PHASE switch is pressed in, the yellow LED will light showing that the
input signal is now out-of-phase.
Powering the C03U
The C03U is a condenser microphone, and like all condenser microphones, it has
internal electronics that require an active power supply. Traditional studio condensers are almost always powered by a Phantom Power supply which is usually derived
from the mixing console. The C03U receives its power from the USB bus. Simply
connect the microphone to the computers USB port and the microphone is ready to
operate. The C03U features a power on LED, which will illuminate when USB power is
present.
6
Operating the C03U
1
Using the PAD Switch
The C03U includes a PAD switch, which you can
use to lower the input sensitivity of the microphone. When the PAD switch is set at the 0dB position the PAD is bypassed and there is no effect on
the signal. When the PAD switch is set to the –10dB
position, the microphone’s input sensitivity will be
lowered by 10dB. You can use the PAD when you
are miking loud sound sources with a high SPL
(Sound Pressure Level).
2
Using the Hi-Pass Filter
The C03U offers a user selectable hi-pass, or low-cut filter, which you can use to eliminate any unwanted low frequency reproduction. When the Hi-pass Filter is is set to
the “flat” (indicated by the straight line) position,
there is no effect on the signal. When the Hi-pass
switch is set to the “roll-off” position (indicated
with the angled line), a 12dB per octave low-cut
at 100Hz is applied to the signal. This can be
extremely useful for removing low frequency stage
rumble, wind noise during outdoor use, and filtering out lows from drums when used as overhead
cymbal microphone on a drum kit.
Polar Patterns
The most important characteristic of any microphone is its directionality or “pickup
pattern”. The C03U’s versatile dual capsule design is capable of producing three useful
pick up patterns; Cardioid, Omni, and Figure 8. It is easy for you to select the pickup
pattern using the C03U’s pattern selection switch located on the rear of the microphone. When choosing a pattern, you should be aware of the phenomenon known as
the “proximity effect”.
2
1
ENGLISH
Simply put, proximity effect is the change in frequency response as the microphone
position is changed relative to the sound source. Any microphone exhibits its best
frequency response when pointed directly at the sound source (on-axis). Depending
on the pickup pattern, the low frequency response will increase, sometimes
greatly, when positioned less than 12 inches away from the sound source (off-axis).
Understanding and knowing how to use the proximity effect can be a tremendous
help in getting just sound you looking for. The following sections details the three
available pickup patterns.
7
Operating the C03U
3
Super Cardioid
While Omni and Bi-directional microphones are very useful for a variety of specialty
applications, the majority of miking situations in recording and live sound require
uni-directional or Cardioid microphones. The C03U condenser’s pickup pattern is
Super-cardioid, which offers even more side-to-side rejection. The uni-directional
nature allows for better separation of instruments in the studio and more control over
feedback in live sound reinforcement. To select the
ENGLISH
Super Cardioid pickup pattern, set the pattern selection switch to the center, Super Cardioid position
indicated by the “heart shaped” icon. When positioned correctly, the Super-cardioid pickup pattern
allows you to pick up more of the sound you want
and less of the sound you don’t want.
4
Omni
Omni, or omni-directional, microphones pick up sound from all directions. To select
the Omni pickup pattern, set the C03U’s pattern selection switch to the right, “O” position. You can use the omni pickup pattern if you want to capture the ambient sound
and natural reverb in a room where an instrument or voice is being recorded. The
Omni mode is also great for recording ensemble
performances from groups of vocals, brass, woodwind and other instruments with the artists facing
each other in a circle around the microphone. As an
added benefit, the omni pattern is the least susceptible to the proximity effect. This can be extremely
useful when recording artists who have a tendency to move their instrument, including their voice, around the microphone while performing. In these situations, using
a cardioid pattern can result in the frequency response changing tremendously with
just a few inches of movement resulting in a recorded track with the lows moving up
and down in volume. Using the omni pick up pattern can help control these tricky
miking situations allowing you to capture the best performance without inhibiting
the talent by forcing them to try to stay in a fixed position.
5
Figure 8
Figure 8, or bi-directional, mics pick up the sound
directly in front and back of the microphone while
rejecting the sound on the left and right sides. To
select the Figure-8 pickup pattern set the C03U’s
pattern selection switch to the left, “8” position.
In this mode it’s almost like having two identical
microphones facing back-to-back to each other. This can be an ideal setting for capturing two artists singing a duet or laying down a background vocal track. Having the
two artists face each other while performing can help capture the emotions that may
other wise be missed if two microphones are used. You can also create some interesting slap back echo effects by positioning the C03U in Figure-8 pattern between a
recorded instrument and a particular wall in the studio. The rear capsule will pick up
the reflection of the sound off the wall, and by changing the distance of the microphone from the wall you can actually change the delay time of the echo.

Operating the C03U
Microphone Placement
In order to maximize the sound quality, you must pay careful attention to the placement of your C03U and how it is positioned for the instrument or vocalist that you are
miking. All microphones, especially uni-directional or cardioid microphones, exhibit a
phenomenon known as “proximity effect.” Very simply put, proximity effect is a resulting change in the frequency response of a microphone based on the position of the
mic capsule relative to the sound source. Specifically, when you point a cardioid mic
directly at the sound source (on axis) you will get the best frequency response, however when you start pointing the microphone slightly away (off axis) you will notice
the low frequency response dropping off and the microphone will start to sound
thinner.
For most vocal applications you’ll want to position the microphone directly in front
of the artist. The same may be true for miking instruments, however, you can make
some pretty amazing equalization adjustments by slightly changing the angle of
the capsule to the sound source. This can be a very useful technique in capturing
the optimum sound of drum set, acoustic guitar, piano or other instruments in a live
room or sound stage. Experimentation and experience are the best teachers in getting good sounds, so plug in!
Setting Up the Signal Level
You can adjust the C03U's internal digitally controlled analog Input Gain stage by
using the Softpre applet, or you can control the input gain by using the software
control in your computer's operating system and/or digital audio workstation. Either
way, the purpose of the mic trim control is to optimize the amount of good signal to
any associated noise. A good mic pre, like the C03U software control panel, will also
have LEVEL or CLIP indicators. To set a good level on the mic, set the C03U up in front
of the desired sound source and slowly raise the input trim control until you see the
CLIP or Peak indicator light up. Then, turn the input trim control down until the indicator does not light any more. For more information on setting the Input Gain with the
Softpre applet, see the section "INPUT GAIN - Fader" on page 7 in this manual.
ENGLISH
P-Popping
P-Popping is that annoying pop that you can get when the microphone diaphragm
gets a blast of air from a vocalist pronouncing words with the letter “P” included.
There are a few ways to deal with the problem including using an external pop filter.
Some famous engineers have relied on an old nylon stocking over a bent clothes
hanger, which actually works very well. You can also try placing the microphone
slightly off axis (on a slight angle) from the vocalist. This can often solve the problem
without using an external pop filter. However, for a more reliable solution, try an
external pop filter like the Samson PS-01.
Stand Mounting the C03U
The C03U can be mounted to a standard microphone stand using the included swivel
mount adapter. If you are using a U.S. 5/8” mic stand, you will need to remove, by
unscrewing, the Euro stand adapter. Simply screw the swivel adapter on to your mic
stand or boom arm. Now, loosen the thumbscrew and adjust the microphone to the
desired angle. Once set, tighten the thumbscrew to secure the microphone in place.

Using the Optional SP01 Shock-Mount
Using the Optional SP01 “Spider” Shock-Mount
For additional isolation the C03U can be
fitted on the optional SP01 “Spider” shock
mount. Follow the steps below the to install
the SP01.
ENGLISH
• First, screw the SP01 shock mount onto
your mic stand or boom arm. If you’re
using a US 5/8” mic stand or boom,
remove the Euro adapter.
• Remove the C03U swivel mount by
rotating the threaded collar counterclockwise as shown in figure 1.
• Install the C03U into the SP01 by fitting
the microphone into the center of the
web, positioning the C03U onto the bottom mounting plate.
• Secure the SP01 by reinstalling the
threaded collar, rotating clockwise until
tight. (Figure 2)
• Now, loosen the thumb screw to adjust
the angle of the microphone and position the C03U to the desired location.
Once set, tighten the thumbscrew to
secure the microphone in place.

Obtention d’un niveau optimal
L’un des principes de base de l’audio réside dans
l’obtention d’un niveau de travail convenable. Même
les petits mélangeurs ou les enregistreurs multipistes
de base sont équipés de réglages qui affectent le
niveau du signal dans son trajet entre la source et les
enceintes, ainsi que le niveau de votre casque ou de
votre système d’écoute. Ces réglages sont : Gain de
préamplification, égalisation, départs et retours Aux, Faders de voies, réglages de
niveau de bus ou de groupe, et enfin, le Fader général. N’oublions pas le train de 5:15,
dont la trompe est tellement bruyante que vous pouvez l’entendre 10 km à la ronde
pendant que vous essayez de faire une prise de guitare classique, malgré le fait que
vous ayez utilisé toutes les couvertures de la maison pour essayer d’isoler les fenêtres
de votre studio. Mais c’est une autre histoire. Vous devez savoir qu’à chaque fois que
vous modifiez un réglage dans le trajet du signal, vous modifiez probablement le
gain quelque part en aval du trajet. Veillez à contrôler les afficheurs de niveau d’entrée et de sortie pour éviter de saturer le signal. Souvenez-vous que votre oreille reste
le meilleur outil d’appréciation. L’obtention d’un bon niveau doit être approchée de
façon technique et contrôlée à l’écoute.
FRANÇAIS
Fader de GAIN D’ENTRÉE
Le C03U est équipé d’un étage interne de réglage du niveau d’entrée analogique
contrôlé de façon numérique par le Fader du logiciel du C03U. La plage du Fader est
réglable de -62 à +48 dB. Le C03U peut accepter tous les types de niveaux à l’aide du
Fader de GAIN D’ENTRÉE, qui détermine le niveau du signal d’entrée. Il est conseillé
de commencer avec un niveau faible et de monter progressivement le réglage.
Contrôlez le niveau d’entrée sur l’afficheur et essayez de régler le gain d’entrée de
sorte que l’afficheur de niveau reste juste en dessous du niveau d’écrêtage CLIP. Le
témoin CLIP s’allume lorsque vous surchargez les circuits, ce qui crée de la distorsion.
Lorsque cela se produit, baissez le Fader de gain d’entrée. Le témoin CLIP demeure
allumé en rouge jusqu’à ce que vous cliquiez dessus.
