IntroductionThe CL8a is a condenser microphone and therefore requires 48V phantom power. Phantom power is provided by a mixer’s preamplifier channel or if necessary, an external phantom power supply and sent to the microphone along a balanced microphone cable. To ensure the longevity of your equipment, and is good mixing etiquette, always turn down the master fader and monitor controls to zero when switching the phantom power on or off. Poor microphone performance can be attributed to phantom power issues. If you notice that the microphone is exhibiting reduced signal output, increased noise, or decreased headroom (distortion), there may be an issue with the phantom power supply or the microphone cables. When connecting the CL8a to a mixer or audio interface, be sure that the input is of microphone level and be sure that the phantom power is engaged as explained in the previous section. Most mixers and interfaces will offer a microphone input with mic trim (usually called Trim or Gain) control. The purpose of the mic trim control is to optimize the amount of good signal to any noise associated with the mixers electronics. A good mic preamp with trim also will have a PEAK or CLIP indicator. To set a good level for the microphone, set the CL8a up in front of the desired sound source and slowly raise the mic trim control until you see the PEAK LED light up. Then, turn the mix trim control down until the LED does not light any more. On most mixers, the ideal setting is that the trim control is turned up as much as possible without lighting the PEAK LED.

The CL8a offers a switchable high-pass, which you can use to eliminate any unwanted low frequency content. When the High-pass Filter is set to the “flat” (indicated by the straight line) position, there is no effect on the signal. When the High-pass switch is set to the “roll-off” position (indicated with the angled line), a 12 dB per octave low-cut at 100 Hz is applied to the signal. This can be extremely useful for removing low frequency stage rumble, wind noise during outdoor use, and filtering out lows from drums when used as an overhead cymbal microphone on a drum kit. The CL8a includes a 10 dB attenuation pad that can be selected with the slide switch located below the grill, which lowers the input sensitivity and is used to prevent overloading the onboard preamplifier. Setting the switch to the 0 dB position, the control is bypassed and there is no effect on the signal. When the switch is set to the -10 dB position, the input sensitivity of the microphone will be lowered by 10 dB. This is useful when close miking loud sound sources with very high transient sounds, such as drums, cymbals or brass instruments. Before setting the attenuation pad switch to the -10 dB position, it is advisable to perform a sound check and to optimize the input signal levels using proper gain staging. If distortion is apparent when the performer is singing or playing their instrument at maximum level, work backwards through the signal chain to find out where the distortion exists. First check the microphone preamp level. If it is set to the minimum position and there is distortion, activate the preamplifier pad switch. If the signal level drops and the distortion goes away, then the microphone preamp was overloaded. If the level drops but the distortion remains, then the overload is happening at the microphone input. Set the attenuation switch to the -10 dB position. If the distortion still remains, then either have the performer lower the level of their instrument or move the microphone further away from the sound source. Using the pad switch (A) High-Pass Filter (B)Polar Pattern An important characteristic of any microphone is its directionality or polar pattern. The CL8a features a dual- membrane capsule allowing for a choice of three individual polar patterns: omnidirectional, unidirectional (cardioid), and bidirectional (figure-8). The microphone pattern can be selected using the three- position slide switch on the rear of the microphone. Each pattern has distinct pick-up characteristics with respect to the sensitivity and frequency response to sounds arriving from different directions. The following section discusses some of the features of each pattern, to help you choose the best setting for your application. Omnidirectional - The omnidirectional setting reproduces sound from all directions, (including off-axis), with an even frequency response, which makes it resistant to the phenomenon known as proximity effect. It captures a greater amount of ambient sound than the other settings, and thus will include more of the room sound than when using a directional setting. The omnidirectional setting is great for recording ensemble performances including group vocals, brass, woodwind, and other instruments with the artists facing each other in a circle around the microphone. To select the omnidirectional pickup pattern, set the pattern selection switch to the left position, indicated by the circle icon. Unidirectional (cardioid) - The cardioid pickup pattern is the most widely used for studio and live miking applications. It captures sound in front of the microphone and rejects sound from the sides and back, which allows for better separation of instruments in the studio, and picks up more of the instrument sound in relation to the sound of the room. The separation also allows for more control and more gain before feedback in live sound reinforcement situations. To select the cardioid pickup pattern, set the pattern selection switch to the center position, indicated by the “heart-shaped” icon.ENGLISH

Proximity Effect Cardioid microphones, exhibit a phenomenon known as proximity effect. Proximity effect is a resulting change in the frequency response of a microphone based on the position of the mic capsule relative to the sound source. In general, as the microphone moves closer to the sound source, the bass response increases. Bidirectional (figure-8) - This setting captures sound directly in front and back of the microphone while rejecting sound on the left and right sides, and has minimal off-axis frequency response deterioration. It is very useful in a variety of stereo microphone techniques. The figure-8 pattern can be used to simultaneously capture two instruments or vocalists by positioning the microphone directly between them, so one is addressing the front of the microphone and the other the rear. To select the figure-8 pickup pattern, set the pattern selection switch to the right position, indicated by the “8” icon. For most vocal applications you’ll want to position the microphone directly in front of the artist about 4 to 18 inches. This will pickup the voice while minimizing unwanted background or ambient noise. Slight changes to the angle of the microphone in reference to the sound source can make some pretty amazing equalization adjustments. Experimentation and experience are the best teachers in getting good sounds, so plug in and start creating! Polar PatternMicrophone Placement The CL8a is a great microphone choice for many instrument miking situations. Below is a brief guide on using the CL8a in some typical applications: Vocals Position the microphone directly in front of the artist so that the microphone grille is between 6 to 18 inches away. The closer the artist moves to the microphone, the more the bass or low response increases; this is called proximity effect. To achieve the fullest sound, the vocalist should aim the microphone center line towards their mouth. If p-popping (turbulent bursts of air produced when uttering consonants) is occurring, use a pop filter or rotate the microphone a little bit away from the artist so that sound arrives at the microphone slightly off-center. Acoustic Guitar There are a variety of ways that the CL8a can be used to mic an acoustic guitar. Optimal microphone placement will depend on the type of instrument, and what kind of sound you’re looking to capture. It may be necessary to experiment with various positions to achieve full and balanced tone. When miking a standard steel string acoustic, it is suggested that you begin with the microphone at a distance of 6 to 12 inches from the sound hole, positioned slightly off-axis, and pointing towards the edge of the fingerboard. From this position, moving the microphone towards the sound hole will cause the mic to capture more low frequencies. If, instead, you wish to capture more high-end, or to remove any unwanted boominess, move the microphone toward the fingerboard. Unlike a steel string acoustic guitar, the sound of a nylon string acoustic guitar that is played by finger picking is usually naturally warmer. To record an even, full tone, it is suggested that you begin by positioning the microphone 3 to 6 inches above the center of the bridge. This will help emphasize the higher frequencies and pick up the attack sound of the finger picking. If the microphone is picking up too much low frequency from the sound hole, move the microphone so that it is slightly off-axis from the guitar. If you have a pair of CL8a microphones, try one positioned at the fingerboard and the second over the bridge of the guitar, or have one microphone positioned close to the guitar and the second a few feet away to pick up the sound of the room, blending the two sources together.ENGLISH

Piano The grand piano is a very challenging instrument to capture, and can be miked in a variety of ways. For close miking the piano, position the CL8a just inside the piano, centered between the soundboard and the open lid. The closer you move the microphone toward the instrument the more low frequencies the microphone will pick up. For an ambient recording like that used in a classical performance, position the microphone outside the piano, facing into the open lid. For a more contemporary ensemble sound, place two CL8a microphones in the piano, positioning one over the low strings and one over the high strings at a distance of 6 to 12 inches apart. When miking an upright piano with a single microphone, position the microphone just above and in front of the piano with the top open, centered over the instrument. If you have a pair of CL8a microphones, position the microphone over the open top of the piano with one microphone over the bass strings and one over the high strings. You can also position two mics in front of the kickboard area approximately 8 inches over the bass and high strings. Guitar Amp Placement of the microphone when recording an electric guitar can impact the tone as much as the choice of instrument and amplifier. Guitar amps are usually close- miked but consideration must be made for the type of signal the amp will produce. While condenser microphones like the CL8a have fast transient response, they cannot handle extremely high SPL. The CL8a should be placed approximately 4 inches from the grill of the amp. If the signal is distorted, activate the onboard 10dB pad. For a brighter sound, the microphone should face the center of the amplifier’s speaker cone. By moving the microphone off of the center of the speaker, the sound becomes mellow, rolling off some of the high frequencies. To add more of the room sound, the microphone can be angled away from the amplifier, or placed further away from the speaker. Microphone PlacementOverhead Drum Kit The CL8a performs exceptionally well when used as an overhead drum set microphone. You can position the microphone approximately centered 5 feet in front of the drum kit 12 to 24 inches above the kit. For stereo miking, use two microphones placed over the drum set at a distance of 3 to 6 feet. Even though overhead mics are mostly for the cymbals, you can get the entire kit to sound great with just two microphones. You should experiment with the exact placement depending on the size of the room and whether you’re looking for an ambient or close-miked sound. Microphone PlacementENGLISH

P-Popping Sometimes when recording vocals certain plosive consonants (like hard “P” and “B” sounds) overload the input of the microphone which causes clipping and adds distortion to your recording. It is advisable to use a pop filter to reduce the effect of the blasts of air from vocalists when pronouncing words that include these hard consonant sounds. The pop filter also helps to protect the microphone element from moisture. You can also try placing the microphone slightly off axis (on a slight angle) from the vocalist. This can often solve the problem without using an external pop filter. Stand Mounting the CL8a The CL8a can be mounted to a standard microphone stand using the included swivel mount adapter. If you are using a 5/8” mic stand, you will need to remove the Euro stand adapter. Simply screw on the swivel adapter on your mic stand or boom arm. Now, loosen the thumbscrew and adjust the microphone to the desired angle. Once set, tighten the thumbscrew to secure the microphone in place. Using the CL8aFor additional isolation the CL8a can be fitted on the optional SP01 spider shockmount to isolate the microphone from vibrations and mechanical noises transmitted through the mic stand. Follow the steps below to mount the CL8a to the SP01. Attach the SP01 to a mic stand by screwing the shockmount onto the stand. Remove the CL8a swivel mount by rotating the threaded collar counterclockwise. Install the CL8a into the SP01 by fitting the microphone into the center of the web, positioning the CL8a onto the bottom mounting plate (A). Secure the SP01 by rotating the shockmount’s the threaded collar clockwise until tight (B). To adjust the angle of the CL8a, loosen the thumb screw on the SP01, position the shockmount and microphone to the desired position. Once set, tighten the thumbscrew to secure the microphone in place (C). Note: Be careful not to cross thread or over tighten the threaded collar or thumb screw. Optional SP01 shockmount
