Mojave Audio



	The Mojave Audio Story David Royer started Mojave Audio in 1985 in the garage of his house. The location was Anaheim, California, and Mojave Audio was a one-man, custom pro audio gear shop. David is best known for his ribbon microphone designs with Royer Labs, but he originally started out designing and building vacuum tube microphones, mic pre's and compressors for engineers in the Los Angeles area. His custom condenser mics have been used on many hit recordings over the years. For engineers who know about them, David's early tube condenser mics are highly prized possessions. Royer Labs is a ribbon microphone company and it will continue to concentrate solely on ribbon mics. But David knows his way around tubes and over the years he has developed a number of condenser microphones. In 2001, he worked up a kit that let people modify Marshall MXL 2001 mics into higher quality tube condenser microphones. He wrote an article for Tape Op Magazine on how to perform the modification, and later wrote a 2nd article on modifying a Marshall small diaphragm mic into a tube condenser microphone. The kits were well received and a number of engineers modified their microphones according to David's design, but both kits were discontinued in May 2005 so Mojave Audio could concentrate on developing and producing our new line of pro audio gear. The first Mojave Audio production product is the new MA-200 vacuum tube condenser microphone. There will be more products released over the next few years, including a small diaphragm tube condenser mic that is already being beta tested by a few of our LA based engineer pals.

	MA201 The MA-201fet is a large diaphragm, phantom-powered, solid-state condenser microphone with a fixed cardioid pattern. With its roots in a lineage of microphone designs by David Royer, the MA-201fet gives warm, full-bodied reproductions of vocals and instruments, with none of the shrillness and high frequency distortion artifacts that are often encountered with modern condenser microphones. Utilizing a 3-micron gold-sputtered capsule, high-quality Jensen audio transformer, military-grade FET and custom designed low-noise resistors, the MA-20fet performs at a level reminiscent of some of the best loved classic condenser microphones. Each MA-201fet microphone is carefully tested and evaluated, then packaged in its protective case with a professional grade shockmount. Features: Hand-selected 3-micron 1” capsule Jensen audio transformer Military-grade FET Custom designed low-noise resistors Ultra clean signal path Recommended applications: Vocals Voice Over and Broadcast High SPL sources, such as Kick Drums and Bass Guitar Amps Electric Guitar Piano Drum Overheads, Drum Rooms Acoustic Instruments Technical Data TRANSDUCER TYPE: Externally polarized pressure gradient capacitor DIAPHRAGM: 1-inch diameter, gold sputtered DIAPHRAGM THICKNESS: 3-micron POLAR PATTERN: Cardioid FREQUENCY RESPONSE: 20 Hz-20kHz, + 3dB SENSITIVITY: -39 dB re. 1V/pa MAXIMUM SPL: 125 dB DISTORTION: <1% @120dB SPL, <3% @134dB SPL SELF NOISE: 14dB nominal, not to exceed 16dB (A weighted) IMPEDANCE: 550 ohms, transformer balanced (Jensen) POWERING: 48VDC phantom power; current .68mA. DIMENSIONS AND WEIGHT: Carrying case with microphone, shock mount: 10” x 9” x 4.5”, 4 lbs. Microphone: 7 5/8” x 2”, 1 lb.

	MA200 The MA-200 is a large diaphragm, vacuum tube condenser microphone with a fixed cardioid pattern. Born to a lineage of fine microphone designs by David Royer, the MA-200 gives warm, full-bodied reproductions of vocals and instruments, with none of the shrillness and high frequency distortion artifacts that are often encountered with modern condenser microphones. Utilizing hand-selected 3-micron capsules, high-quality Jensen audio transformers and military-grade JAN 5840 vacuum tubes, the MA-200 performs at a level reminiscent of some of the best loved classic condenser microphones. The MA-200 power supply can be set for 115V and 230V, 50 or 60 Hz, through an internal switch (100V is also available). Each MA-200 microphone, power supply and cable set is burned in for 24 hours, carefully tested and evaluated, then packaged in its protective case-within-a-case. Features: Hand-selected 3-micron capsule Jensen audio transformer Military grade JAN 5840 vacuum tube Internal switchable power supply voltage Ultra clean signal path Recommended applications: Use anywhere you would use an expensive, large diaphragm tube microphone: Vocals Broadcast Acoustic Instruments Piano Drum Overheads, Drum Rooms Orchestral Recording Choral Recording Voice-overs Technical Data: TRANSDUCER TYPE: Externally excited capacitor type DIAPHRAGM: 1-inch diameter, gold sputtered DIAPHRAGM THICKNESS : 3-microns POLAR RESPONSE: Cardioid FREQUENCY RESPONSE: 30 Hz-18 kHz, ±3dB SENSITIVITY: -37dB re 1V/pa MAXIMUM SPL: 120dB DISTORTION: head amp only, <1% @117dB SPL, <3% @ 125dB SPL SELF NOISE: 14db nominal, not to exceed 16db (A Weighted) IMPEDANCE: 200 ohms, balanced using an output transformer VACUUM TUBE: 5840 - pentode tube wired for triode operation POWER REQUIREMENTS: 100-120VAC; 220-240VAC, 50 or 60 Hz. Power consumption approx. 10 watts. DIMENSIONS AND WEIGHT: Carrying case with microphone, power supply, shock mount and cables: 13 lbs. Microphone: 7 5/8 X 2, 1 lb.

	MA100 The MA-100 is a small diaphragm, vacuum tube condenser microphone with interchangeable cardioid and omnidirectional capsules. The latest in a lineage of successful microphone designs by David Royer, the MA-100's 'cathode follower' design allows use on high SPL instruments such as drums and guitar amplifiers, as well as the more common applications of a small diaphragm, vacuum tube condenser microphone, such as acoustic instruments, cymbals, stereo pairs and pianos. Featuring hand selected 3 micron capsules, high quality Jensen audio transformers and military-grade JAN 5840 vacuum tubes, the MA-100 performs at a level reminiscent of some of the best loved classic small diaphragm tube condenser microphones. The MA-100 power supply can be set for either 115v or 230v via an external switch. Each MA-100 microphone, power supply and cable set is burned in for 24 hours, carefully tested and evaluated, then packaged in its protective case. Small Diaphragm - Big Sound! Why choose a small diaphragm microphone? Because small diaphragm microphones offer some distinct advantages over their larger brethren: More consistent polar pattern Better transient response Ease of placement Why choose an MA-100 ? Extended low-frequency response High SPL handling capability - try putting your large-diaphragm mic on a snare drum! Features: Interchangeable cardioid and omnidirectional capsules Hand-selected 3-micron capsule Jensen audio transformer Military grade JAN 5840 vacuum tube External switchable power supply voltage Ultra clean signal path High SPL handling capability Recommended applications: Acoustic Instruments Drums Guitar Amplifiers Piano Stereo Pairs (X/Y, MS, Decca Tree, Blumlein, etc.) Orchestral Recording Choral Recording Voice-overs and Broadcast Percussion Technical Data: TRANSDUCER TYPE: Externally excited capacitor type DIAPHRAGM: .8" / 20.5 mm diameter DIAPHRAGM THICKNESS: 3 microns POLAR RESPONSE: Interchangeable Cardioid and Omnidirectional Capsules FREQUENCY RESPONSE: 20 Hz - 20 kHz, ±3dB SENSITIVITY: -37dB re 1V/pa\| MAXIMUM SPL: 120dB DISTORTION: head amp only , not to exceed .4% @ 140 dB SPL SELF NOISE: Not to exceed 16dB IMPEDANCE: 450 ohms, transformer balanced VACUUM TUBE: 5840 pentode wired as triode, operated as a unity-gain buffer stage (cathode follower) POWER REQUIREMENTS: 100-120VAC; 220-240VAC, 50 or 60 Hz.
