Power Requirements

The MXL Revelation uses an EF86 tube that requires a dedicated power supply unit (included with your microphone). Even if your mixer has phantom power, it is recommended that you defeat the phantom power as a precautionary measure when it is not needed to power other mics that you might also be using.

This supply is switchable between 110 volts and 220 volts AC. In North America, the microphone ships in the 110-volt AC position and in the 220-volt AC position for export. However, you always want to ensure that the power supply voltage is correctly set for your local voltage as permanent damage to the microphone and/or power supply may occur if the incorrect voltage setting is selected. Every Marshall Electronics MXL microphone has been thoroughly checked before shipping; so if you do not hear the sound, check that the power supply is switched on.

Caution Do not “hot plug” the mic. Always ensure that the power supply is off when plugging and unplugging the included 7-pin cable from the microphone to avoid damaging the microphone and power supply.

• Bass Roll-off Switch
  The Revelation power supply features a bass roll-off switch to help reduce the proximity effect. The proximity effect is a distortion that often occurs when a sound source is too close to the mic. Some microphone patterns boost bass as you get closer to the microphone; cardioid mics, for instance, tend to boost bass. The bass roll-off switch reduces the low frequencies for a more full-range sound.

• Phase Switch
  The Revelation also includes a phase switch that allows you to reverse the polarity of the microphone signal by 180 degrees. This can help minimize phase issues when recording with multiple microphones.

Variable Pattern Control Knob

The Revelation features a continuously variable pattern selector located on the Revelation power supply. This knob allows you to alter the polar pickup pattern of the microphone from omnidirectional to figure eight, and everything in between. This can be done with the microphone turned on without causing any damage to the unit; however, it is recommended that you mute your speakers when changing to a new pattern. To change the polar pattern, simply rotate the knob to customize the microphone’s pickup pattern for your specific recording application. After rotating the knob to a new polar pattern, it will take a few seconds for the capsule to charge back up. During these few seconds, we recommend muting your speakers because you will hear static. Keep in mind that there is no single right way to find the perfect sound. Experimentation with different patterns in different recording situations will be the key.

One of the most popular polar patterns, a cardioid microphone picks up sound from the front of the microphone, has less sound from the sides, and has good rejection of sound to the back of the microphone. The cardioid pattern is well suited for situations when you want to pick up specific sound sources like a guitar within an ensemble and is recommended for recording applications where the acoustics are good but not perfect. For instance, a cardioid pattern is less likely to pick up ambient noise from computers and recording equipment.

An omnidirectional microphone picks up sound equally from all sides of the microphone. Omni-directional microphones are recommended for environments with excellent acoustics as they tend to pick up ambient noise. This pattern is well suited for picking up sound from a wider recording area. Omni-directional mics are less sensitive to plosives, handling noise, and proximity effects.

Commonly referred to as bi-directional, the figure 8 pattern will pick up sounds from the front and back sides of the microphone with equal sensitivity while maintaining a large amount of rejection 90° off access. Figure-8 patterns are the most susceptible to proximity effect and are commonly used in “mid-size” stereo recording setups.

• Ground Lift Switch
  A ground loop is an unwanted interference that can be created when multiple electronic devices improperly share a common ground. The Revelation includes a Ground Lift switch to help prevent such occurrences. If a ground loop is audible (usually a 50-60Hz humming noise), the ground lift switch on the front of the power supply should be set to the ‘lift’ position.

• -10dB Pad
  The Revelation can be used in very loud sonic environments without significant distortion. If you hear distortion from the microphone, engage the “-10dB pad” on the rear of the microphone to the -10dB position. You may also move the microphone farther away from the sound source.

• Shockmount
  The Revelation comes with a custom shock mount specifically designed to handle its large size. Shockmounts decouple the microphone from the mic stand and the environment and can minimize floor noise as well as noise induced by people handling the microphone stand. Shockmounts should be considered “standard equipment” for all recording applications. To mount the Revelation in the shock mount, first, attach the shockmount to the mic stand. With one hand, hold the Revelation microphone inside the basket of the shockmount with the threaded base of the mic resting on the retaining nut at the bottom. With your other hand, rotate the retaining nut until the microphone is securely attached to the shockmount.

• Microphone Cables
  The microphone cable can have a profound effect on the sound of any microphone. Even the finest microphones will sound poor if the interconnect cable allows noise to enter or causes distortion and loss of information. We highly recommend exclusively using the Mogami® cables supplied with your Revelation.

• Care
  Dust and foreign material can degrade the performance of a microphone over time so always store the unit in its case.

• Grill
  The Revelation microphone uses a single-layer mesh grill. This design minimizes standing waves and harmonic distortion. Because this type of grill leaves little protection between the user of the microphone and the capsule, we highly recommend using a pop filter. Use of a pop filter will help protect your microphone’s sensitive capsule, keeping it free from moisture caused by saliva and breath condensation.

Recording Tips and Tricks

Vocals and Dialog

Ideally, you want to record vocals in a relatively “dead” room. If you clap your hands and get an echo effect, you should consider adding some carpet, blankets, drapes, or other sound-absorbing materials. On that note, make every effort to avoid getting too close to the room’s walls. These hard, reflective surfaces can easily complicate the recording process. Move your mic setup toward the room’s center.

Generally, you should position the vocalist roughly 6 – 8 inches away from the microphone. Getting too close to the microphone tends to increase bass response and can create problems with plosive sounds (i.e., those popping Ps, Bs, Ds, and Ts). Getting too far away makes the microphone more subject to picking up room ambiance and creates the effect of the vocalist being in a bowl. While vocalists may need to move about in order to hit those high notes, make every effort to maintain a constant distance from the microphone, as this will provide the greatest tonal balance (see Fig. 1). For the most part, the microphone axis (or center line) should aim toward the nose and mouth to obtain the fullest sound. It’s not a bad idea, however, to experiment with angling the microphone slightly away from the dead center so as to help minimize plosives. Further, you should always place a “pop” filter between the vocalist and the microphone, with the pop filter positioned 3 – 4 inches in front of the microphone. This will greatly increase your ability to achieve the most natural-sounding recordings with minimal interference from plosive sounds. Fixing plosives with audio editing software often creates more of a problem than the plosive itself. The use of a pop filter will also protect your microphone’s sensitive capsule, keeping it free from moisture caused by saliva and breath condensation. Remember—good microphone technique, proper positioning, and the use of a pop filter can make all the difference between a so-so-vocal recording and a great one.

Recording Acoustic Guitar

• Your best results for capturing the acoustic guitar (or any similar stringed instrument) begin with a properly tuned instrument and strings that, while not old, aren’t so new as to create tuning issues due to stretching. There are two optimum points for microphone positioning: either near the bridge or by the twelfth fret.
• While it may seem natural to place the microphone in front of the instrument’s sound hole, doing so usually increases low-frequency response to the point of making the instrument sound “boomy.”
• Twelfth Fret Placement: Placing the microphone roughly 2 – 4 inches from the twelfth fret and aiming directly at the strings will generally produce a warm, full-bodied sound with good tonal balance. In addition, the sound hole’s contribution to the sound will be moderated since the microphone is not pointed directly at it.
• Bridge Placement: Similarly, you can position the microphone so it is 3 – 6 inches from the guitar’s bridge. This will generally produce a somewhat brighter tonal quality. You should also be prepared to experiment with positioning the microphone slightly off-axis should you find yourself capturing too much low-frequency response from the guitar’s sound hole.
• The acoustical characteristics of your room will also have a pronounced effect on your results. A “live” room will produce an overall “brighter” guitar sound, while a “damped” room will produce more of a mellow tone. If you have two microphones, you may wish to experiment using one in close proximity to the guitar as previously described, with the second microphone on a stand a few feet away to capture the room’s ambience. Blending the two sources can produce excellent results.

Recording an Amplified (Electric) Guitar

• While the electric guitar can certainly be recorded directly, there are times when there is simply no substitute for the sound of a real amplifier. Guitar amps have particular gain stages that facilitate the popular “crunch” guitar sound. While digital modeling and processing systems certainly have their place, they may not have the same level of realism as the sound from an amplifier. A small guitar amp can be just as effective for this application as a stack because you don’t necessarily need to “crank” the volume.
• Instead, you want to increase the amp’s initial gain to achieve the desired amount of overdrive.
• Typically, a guitar amp is close-miked to achieve the highest direct sound. Placing the microphone roughly 4 inches from the grill, aimed directly at the center of the loudspeaker will produce the most “edge” to your sound. By angling the microphone slightly off axis and towards the wall, you can add more “room sound.” Experimentation is a key factor in achieving the sound you are looking for (see Fig. 3).
• The placement of the amp is another important factor. If the amplifier sits on a carpeted floor, you are more likely to reduce the amount of brightness in the sound. Similarly, elevating the amplifier off the floor may result in a loss of low end. If you’re looking for a big reverberant tone, placing the amp and microphone in the bathroom is another popular technique. The hard tiles and other reflective surfaces can do wonders for a dull sound. In this case, move the microphone back a few feet from the loudspeaker and crank it up!

Recording the Piano

The piano is one of the most challenging instruments to record, and many problems stem from the quality and maintenance of the instrument itself. You’ll obtain the best results by using an instrument that has just been tuned and is in good mechanical condition.

The piano is generally recorded using the close miking technique. Ideally, you’ll want a minimum of two microphones. Usually, the microphone capturing the higher strings is assigned to the left channel, and the microphone capturing the lower strings is assigned to the right channel in the final stereo mix, though the stereo spread generally is not hard left and right. While a single microphone can be used, the lower and upper extremities of the instrument will likely be compromised.

• Grand Piano: For the upper strings, position the microphone approximately 8 inches from the piano hammers (to reduce mechanical noise) and 8 – 11 inches above the strings, with the Pan position set to the left of the center. For the lower strings, position the microphone toward the far end (away from the keyboard) roughly 6 – 12 inches from the end and 8 – 11 inches above the strings, with the Pan position set to the right of center. Position the piano’s lid at full stick (see Fig. 4A). If you are using a single microphone, position the microphone approximately 8 inches from the piano hammers (to reduce mechanical noise) and 8 – 11 inches above the strings – centered over the piano’s mid point. The pan position should be centered and the piano’s lid should be at full stick.
• Upright Piano: With an upright piano, the two microphones are generally placed either just over the top of the piano with the top open, or you can remove the piano’s front panel beneath the keyboard and place the microphones below.
• Front Panel Placement: For the upper strings, position the microphone approximately 8 – 11 inches away from the strings, with the Pan position set to the left of the center. For the lower strings, position the microphone 8 – 11 inches away from the strings, with the Pan position set to the right of the center (see Fig. 4B).
• Single Microphone / Open Top: If you are using a single microphone, it is generally recommended that you record from above, as placement of the microphone in the lower center may interfere with the performer’s ability to access the pedals and the microphone will likely pick up excessive pedal and other mechanical noise. Position the microphone just over the open top, centered over the instrument (see Fig. 4C).

Recording a Drum Set

Like the piano, capturing the drums can be quite a challenge, if for no other reason than the fact that you must be very careful to avoid positioning the microphone(s) where they could be hit! Ideally, you’ll want a minimum of two microphones for this job, though a single microphone can be employed.

• Stereo Overhead Pair: Position the two microphones approximately 16 – 20 inches above the performer’s head, separated laterally by roughly 2 – 3 feet, and placed 5 – 6 feet out in front of the drum kit. Adjust the two microphone’s Pan position so that you achieve a good stereo spread, though generally not hard left and right (see Fig. 5A).
• Single Overhead Microphone: Position the microphone approximately 16 – 20 inches above the performer’s head – centered in front of the drum set, and placed 5 – 6 feet out in front. The microphone’s Pan position should be centered for mono drums (see Fig. 5B).

For best results, record the drums in as acoustically “dead” a room as you can. If the room is live, the sharp attack transients of the drum kit will only become that much more difficult to capture if the room has hard, reflective surfaces, resulting in a muddy sound without any real definition. Further, you should always record the drums dry and add signal processing after the fact.
