Introduction

Congratulations  on  your  purchase  of  M-Audio’s 
Sputnik multi-pattern vacuum tube large-diaphragm 
condenser  microphone.  Studio  artists  around  the 
world  rely  on  M-Audio  microphones  to  capture 
acoustic  performances  with  clarity  and  accurate 
tonal  balance.   The  Sputnik  tube  microphone  from 
M-Audio  improves  upon  that  reputation  as  a  top-
of-the-line  solution  for  applications  requiring  the 
smoothest,  world-class  sound.    Engineered  to  the 
highest  sonic  standards,  the  Sputnik  addresses  the 
needs of the most critical professional users.  

The Sputnik microphone represents the culmination 
of  over  a  year  of  design  and  development.    Based 
on a classic vacuum tube design and manufactured 
in  modern  facilities  to  exacting  standards,  this 
multi-pattern,  dual-sided  large-diaphragm  studio 
condenser  mic  delivers  the  lush,  classic  sound 
normally associated with rare and expensive vintage 
mics like the Neumann U47 and AKG C12. In fact, its 
rich low-mid and smooth upper-mid response makes 
it a good bridge between these two venerable mics.

The  Sputnik’s  combination  of  military-grade 
vacuum tube, ultra-sensitive gold evaporated Mylar 
diaphragm,  solid  brass  construction,  and  multiple 
polar  patterns  makes  it  ideal  for  a  wide  variety  of 
voices,  instruments,  and  applications—especially 
putting  that  signature  sound  in  the  spotlight. 
Engineered from scratch, we designed Sputnik with 
input  from  some  of  L.A.’s  top  recording  engineers 
and  producers—and  it’s  an  instant  classic  in  their 
hands.  We are pleased to present what we believe 
to  be  the  most  versatile  and  natural-sounding 
microphone  solution  for  professional  and  high-end 
applications.

Using the Sputnik 

Microphone

Standard Operation

Even  if  you’re  a  seasoned  expert  in  microphone 
use  and  placement,  we  recommend  you  read  the 
following  instructions  when  setting  up  the  Sputnik 
for the first time.  

BEFORE YOU GET STARTED...  

The  Sputnik  power  supply  comes  factory 
programmed  for  100V~50/60Hz,  120V~50/
60Hz,  or  240V~50/60Hz  operation.   The  label 
on the bottom face of the power supply indicates 
the AC mains voltage operation.  The only way to 
change it is by altering the internal circuitry, but 
you (the customer) cannot do that without voiding 
your warranty.  Before using the mic, please check 
the label on the bottom of the power supply unit 
to  make  sure  it  is  set  up  to  accept  the AC  line 
voltage  in  your  location.  (This  should  not  be  a 
problem if you bought it in the country in which 
you are using it.)

However, if you need to use it in another location 
with a different AC mains voltage, we recommend 
you use a high-quality general-purpose step-up or 
step-down transformer, rather than one of those 
inexpensive  voltage  converters  suitable  for  an 
electric razor.  If you use the latter, rather than the 
former, the voltage output may be a square wave 
(rather  than  a  sine  wave)—which  will  probably 
result in noisy operation and will eventually cook 
the mic!

Please note that the mains fuse is user replaceable.  
If you need to change it, please follow the table on 
the bottom of the power supply in order to select 
an  appropriate  fuse  with  the  proper  current 
rating.

Now that you’ve ensured that the power supply is 
set to the correct voltage, you can begin to set up 
the Sputnik mic.

1)   First, make sure the power supply is turned off 

(and preferably, unplugged from the wall).

2)   Take the Sputnik 7-pin cable and connect it to 

the  female  socket  on  the  back  of  the  power 
supply.    (Facing  the  arrow  indentation  on  the 
male  plug  upward  will  help  you  align  the  pins 
correctly.)
