INTRODUCTION

Congratulations  on  your  purchase  of  a  Mojave  Audio  MA-300  Multi-pattern  Vacuum  Tube 
Condenser  Microphone.  Your  MA-300  was  carefully  designed  and  constructed  using  only  the 
finest materials. The MA-300 microphone is capable of delivering superb performance and, with 
minimal care, will do so for many years. Your MA-300 was thoroughly tested and given a 24-
hour factory burn in prior to shipment.

The  MA-300’s  capacitor  capsule  and  electronics  are  adapted  from  mid-1950’s  design  practice.  
The  MA-300  utilizes  a  U.S.  made,  military-grade,  low  noise  sub-miniature  vacuum  tube  and  a 
Jensen  audio  output  transformer.  By  utilizing  modern  components,  the  microphone  system 
emulates  the  performance  of  “classic”  tube  microphones  without  using  esoteric,  unreliable,  or 
hard to find components.

The  MA-300  is  guaranteed  to  perform  as  specified  and  is  suitable  for  recording  even  the  most 
demanding music, provided that the microphone is used sensibly.

For  optimum  performance  from  your  microphone,  please  read  this  manual  thoroughly  and 
familiarize yourself with the proper use of the MA-300.

UNPACKING AND INSPECTION

Carefully  unpack  your  MA-300  and  verify  that  all  of  the  accessories  included  with  the 
microphone are accounted for. Do not discard any packing materials! If anything is missing or 
damaged, contact your dealer or Mojave Audio immediately.

Items included with the MA-300 are:

1. MA-300 microphone inside an aluminum style carrying case.
2. AC operated microphone power supply.
3. 16-foot microphone cable with 7-pin male and female connectors.
4. MA-300 shock mount and European adapter (fitted to shock mount).
5. AC power cable for power supply - molded IEC business machine type with plug. 
6. Rugged carrying case for all above items.

Verify that the serial number of your MA-300

 

matches correctly with the one on your receipt. The 

MA-300 serial number can be found 

 

inside the microphone housing. To access, simply unscrew 

the  bottom  ring  and  slide  the  body  off.  When  corresponding  with  Mojave  Audio  about  your 
microphone  or  when  service  is  required,  we  will  need  to  know  the  serial  number,  so  keep  it 
handy.
