Congratulations on your purchase of the SV33

High Denition Studio Vocal Microphone

The SV33 Studio Microphone is the culmination of two decades of engineering and

innovation at Earthworks Inc., the goal of which was to celebrate the human voice by

revolutionizing the way in which one can capture the full depth of nuance and emotional

expression. The objective of this manual is to provide a basic understanding of the fea-

tures and capabilities of this new microphone as well as some fundamental information

to help you get started. As with all new technologies, the innovation process continues

with you in your discovery of what is now possible.

• Cherry-wood Box - The SV33 box is hand-crafted from solid cherry-wood, provid-

coupled with its timeless aesthetic will protect your microphone for years to come.

• Pivot Arm - Allows mounting the SV33 on a stand or boom and enables rotation

along either the vertical or horizontal axis. The microphone is constructed to pro-

vide mechanical isolation, however the pivot arm does not provide shock absorp-

tion and can be substituted with a shockmount (available as an optional accessory)

if needed.

Stand and Boom Mounting

1. Because the mass and weight of the SV33

can introduce complexity into the mounting

process. It is recommended to rst remove

theSV33fromthePivotArmbyunscrewing

theknurledblackringwithyourngers(Fig-

ure 1). Gently set the microphone aside in a

safe location until you are ready to complete

step 3.

2.MountthePivotArmontothemicrophonestandor

boom(Figure2).

3. Insert the threaded end of the microphone into the knurled

blackring,(Figure3)androtatetheringuntilitisngertight

(do not use tools to tighten).

mounting in order to

avoidlooseningofthepivotarmfromtheboomduetorotationaltorquefromtheweight

of the microphone.

Preamps & Input Capabilities

The SV33 can provide a very clean output of up to 10 volts. However, some preamps

are unable to handle this amount of input level. Be aware of the limitations of your

preamps and choose one that can handle high input levels. The use of electronically

balanced inputs is recommended. If you use a transformer preamp, it is suggested that

younotpushittoohard.Onlyaveryhighqualitytransformercancleanlyhandlethe

highlevelsandlowfrequencyoutputoftheSV33.

Connecting the SV33

TheSV33requires24-48voltphantompower.Aswithallcondensermicrophones,the

SV33 “thumps” when phantom power is applied or removed. Before connecting the

microphoneorapplyingphantompower,makesurethechannelismuted.Connectthe

SV33usingahigh-quality3-pinXLRmicrophonecable.Wait15to20seconds(upto

1 minute with transformer-coupled inputs) before unmuting the channel as the internal

circuitry takes time to stabilize.

SV33 Use and Fundamentals

The SV33 is capable of delivering excellent results with only modest attention given to

roomacousticsandconventionalmicrophoneetiquette;However,thefollowingguide-

lines and suggestions are presented to help achieve consistently exceptional results.

Microphone Placement

At its core, the SV33 has been designed to pick up a wider array of sound emanating

fromthehumanbodyandvoice.Whenaperformerspeaksorsings,therearemultiple

sources generating sound all at once. The contributions of the chest, neck, mouth,

nose and head all sound very different from one another, and their balance continually

changes. As with other complex musical instruments, like drums, piano and guitar, the

position of the microphone greatly affects the sound that is captured. Developing an

understanding of the unique SV33 capabilities will transform microphone placement

into a powerful tool for shaping the desired vocal sound.

The following provides a few examples of what is possible through placement of

this microphone:

 • Tocaptureanaturalvocalsoundthatissimilartowhatalistenerwouldhear

in the room with the performer, consider placing the microphone at the same

  heightastheperformer’smouth,6to12inchesaway,aimedattheirmouth.

 • Reducingthedistanceto3inchesorsowhilestillpositioningthemicinfront

of the mouth allows you to get a drier and more intimate vocal sound. As with

  allmicrophoneplacementtechniquesyoustillneedtomovethemicaround

   fromthatstartingpointtondthedesiredtonalbalance.

 • Adistancegreaterthan12inchescanbeusedtoincreasetheratioofroom

sound to direct vocal sound.

On-axis Frequency Response

TheSV33isatfrom30Hzto33kHz(Figure6).

Proximity Effect

Conventionalstudiovocalmicrophonestypicallyexhibitastrongproximityeffect.Con-

sequentlytheirlowfrequencyresponsevarieswidelywithdistance,droppingoffasthe

performer moves away from the microphone and increasing as they get closer. There

is often only a narrow sweet spot in the range of distances that provides the appropriate

balanceoflowfrequencycontentforaperformer’svoice.

In practice this often leads to a compromise of the overall tonal balance and nat-

uralness of the vocal sound, as keeping the microphone inside the sweet spot for

lowfrequenciesplacesittooclosetothevocalisttocapturethenaturalbalanceof

all of the sound-generating parts of the human body.

The SV33 has been engineered with the gentlest possible proximity effect to avoid

thissortofcompromise.Thismicrophoneslowfrequencyresponseisalmosten-

tirely unaffected by distance, therefore a whole new constellation of use and place-

ment options open up, making it possible to achieve the desired vocal sound.

Polar Response

The polar response of the SV33 provides a wide area of pickup that is consistent in

frequencyandamplitudeoutto70degreesoff-axis(Figures7&8).Italsoprovides

alargeareaofuncoloredrearrejectionbeyond110degreesoff-axis(Figures10-A

&10-B).Dependingonwhatelseishappeningintheroom,aimtherearofthe

SV33towardsourcesyouwanttoavoid.TheSV33’srearrejectionofdeepbass

is also extraordinary.

Pop Screens & Plosives

The SV33 has a built-in screen to keep saliva,

lipstickordirtfromthecapsule;however,when

working close to the SV33 an external pop-

screen should be used as an additional preven-

tion against plosives. It is also recommended to

usethemicplacementsshowninFigures9-A&

9-Btohelpreduceplosives.

Cleaning

When cleaning the windscreen or microphone

body do not spray cleaning solutions onto the

microphone. Instead, use a damp cloth (not too

wet) to carefully remove dirt, grease or lipstick.

If more extensive cleaning of the windscreen is

required, rst remove the windscreen by un-

screwing it from the body of the microphone.

Gently hand wash with warm water and a small

amount of mild dish detergent. After thoroughly rinsing, gently shake any water droplets

from the windscreen and air-dry before using.

Donotattempttoremovethepoplterfromthewindscreenassembly.Donotdirectly

wetorsubmergethebodyofthemicrophoneinanytypeofuid.

If Something Seems Wrong

If you experience unexpected behavior from the SV33 such as noise, distortion or

a lack of output signal, it is recommended that you start by checking the following:

 • Isphantompowerswitchedon?Isitatleast24V,andisthephantompower

  sourcecapableofsupplyingatleast10mAofcurrent?

 • Areyouusinghighqualitymicrophonecables?Failedsolderjointsandpoor

  shieldingfoundinlow-qualitymicrophonecablescanbeasourceofvarious

types of unwanted noise and distortion, and can prevent the proper function-

ing of the microphone and phantom power.

 • Ifdistortionoccurswhenmikingloudsourceslikedrums,electricguitarorvery

  loudvocalistsatcloserange,verifythatthepreampitselfisn’tclipping.Some

preamps will not handle high input levels. Even with the gain control set to mini-

mum they are sensitive enough to overload and clip when loud sources are

captured with high output condenser microphones. In such cases an external

  inlinepad(suchastheEarthworksLP20)canbeusedtoreducethemicro-

  phone’ssignallevelbeforeitentersthepreamp.
