GETTING STARTED QUICKLY
If you are like most people, you probably want to get started right away.
Great! You can read the rest of the manual later to learn the finer points
of recording with a condenser mic. In order to get started, you will need
your new CM-87S mic and XLR Mic Cable, CPS-48 phantom power
supply and a 120 V AC grounded power outlet. You will also need a microphone stand to attach the Shockmount to hold your CM-87S mic. Other
equipment needed may include more XLR cables to connect to a mixer or
recording device.
1. Plug the CPS-48 phantom power supply into the proper AC voltage.
2. With the power off, connect the XLR mic cable to the MIC IN on the power
supply.
3. With the Shockmount connected to a mic stand, place your CM-87S mic
into the shockmount and connect the XLR mic cable to the CM-87S mic.
4. Next, you will need a second XLR cable (not included) to connect the
OUTPUT of the power supply to your input source (ie. mixer, multi-track
recorder etc...).
5. Once connected, you can turn the power supply ON (make sure all volume,
gain knobs, or faders on your input source are turned OFF).
6. Bring the input source’s volume or fader up to 0 dB. Speak into the mic
to test the level.
7. Turn the mixer’s gain up on this channel and stop just before the signal
peaks.
8. Check for transients that can cause the signal to peak by speaking or
singing at the loudest volume you will perform at and adjust the gain up
or down as necessary.
9. With the signal levels set, adjust any EQ that might be needed.
10. You are now ready to record with your CM-87S mic.

CM-87S
CM-87S CONSTRUCTION AND CARE
CM-87 Introduction:
The CM-87S is a studio quality, multi-purpose Large Diaphragm
Condenser microphone. It features a Gold Sputtered, 6 micron element and premium, low noise electronics, all suspended in a
handsome, rock solid, machined casing. The CM-87S also features
a 10 dB pad switch for easy handling of really hot signals and a
low cut switch for reducing hum, rumble, wind and handling
noise. This versatile microphone was developed with the project
studio in mind; so it is equally adept at reproducing stunning vocal
performances as it is at capturing the subtlest nuances of a fine
acoustic guitar. And with a maximum SPL of 135dB (145 dB with
10dB pad switch engaged), the CM-87S is also an excellent instrument and percussion microphone. You no longer have to own a
million dollar studio to get the sound the big boys get. The Carvin
CM-87S is your affordable ticket to awesome studio sound!
Construction and Shockmount:
The internally braced CM-87 capsule is precision mounted
behind a heavy mesh screen of perforated metal with large openings that offers complete protection while maintaining total “acoustic
transparency”. Nestled below, is the low noise, class A circuitry
surrounded by the solid, machined outer shell. When used with
the low cut switch on along with the included Shockmount, low frequency vibration and handling noise are virtually eliminated (-72
dB below 40Hz)!
Power Supply:
The CM-87S comes standard with the heavy duty CPS-48 phantom power supply, ensuring you will never experience noise or distortion during loud dynamic passages due to insufficient current.
The power supply connects to the CM-87S conveniently via the
included XLR mic cable.
*Note: While the CM-87S will operate from any professional quality 48V phantom power supply, we recommend using the CPS-48
unless you are absolutely sure about the quality of an alternate phantom power supply. The Carvin S/L mixing consoles will also provide the proper 48V phantom power and are designed to be used
with the CM-87S. Carvin is not responsible for damage to your
CM-87S caused by a non Carvin power supply.
Flight Case:
The CM-87S, shockmount, power supply and cables, all fit snugly
and safely in a high grade, aluminum alloy flight case so you know
your microphone and accessories are well protected between sessions or during travel. Carvin recommends returning your CM87S to this case after each use.
Care and Feeding:
Condenser microphones do not like to be banged, dropped, tapped,
blown into, shaken or stirred. The gold sputtered element is very
thin and fragile and can easily be stretched or knocked out of alignment. This is true of all large diaphragm condensers. Be very careful with your CM-87S! If you drop it from any distance, the resulting
damage will not be covered under your warranty.
Additionally, these mics don’t like moisture. It is always advisable to use a pop screen (Carvin part #WS87)when micing vocals
to avoid not only overly accentuated “P”, “B”, and “S” sounds, but
also to keep unwanted moisture off of the element. Over time, moisture on the element can attract airborne dust and dirt particles and
gradually degrade the performance of your mic. Carvin advises that
the microphone be kept in its flight case at all times when not in
use. Take a few minutes after every session and put your mic away
properly to help ensure years of top notch performance. Additionally,
always make sure the silicone “moisture absorber” (little white packet
with crystals in it) is packed in the case with your microphone. This
will help to eliminate any moisture or humidity in the case during
storage. You can re-activate a saturated “moisture absorber” by
baking it in an oven at 250 degrees for about 30 minutes. The outer
shell of your mic can be cleaned with a soft damp cloth. Do not
use harsh detergents, solvents, or abrasive materials.
a) Shockmount
The shockmount will fit any standard mic stand. It is designed to hold the CM87S mic while reducing low frequency vibration and handling noise.
b) Low cut switch
The Low Cut switch helps eliminate boomy low end frequencies (
-6dB @ 80Hz)
c) 10dB pad switch
This switch changes the mic’s maximum Sound Pressure Level (SPL) of 135 dB
to 145 dB. Switch to an SPL of 145 dB when recording loud sources.

Connect only balanced XLR cables.
