Congratulations on purchasing Carvin’s

CM30D

drum and instrument

microphones.

The

CM30D

mic kit is capable of handling high sound pres-

sure levels without distortion making them ideal for live or recording close-

miking of all types of drums and percussion instruments.

They are also

accurate for use in sonic reproduction of brass, woodwind and other

instruments producing high sound fields.

FEATURES

• Cardioid pattern allows close miking to minimize bleed-through from other

drums or stage instruments.

• Neodymium element delivers maximum output.

• Up to 140dB SPL handling capacity for distortion free reproduction of

even the loudest drums.

• Transformerless moving-coil dynamic design for enhanced bass and fast

transient response.

• All metal construction for maximum reliability.

• Special rubber shockmount mic holder minimizes floor vibration pick-up.

• Incredibly small, low-profile design for minimum visibility and close

miking placement around the drum kit.

• Gold plated XLR connectors for maximum conductivity.

• Full frequency response for sonic punch with exceptional clarity.

GETTING STARTED QUICKLY

If you are like most people, you probably want to get started right away.

Great!

In order to get started, you will need your new

CM30D

mics and

XLR Mic Cables

.

You will also need a microphone stand to hold your

CM30D

mics.

Carvin recommends our

MS

line of stands (

MS11, MS13,

MS15

).

Other equipment needed is your mixer (sound system or record-

ing system).

1. With the mixer power off, plug the

CM30D

mics into your mixer using bal-

anced

XLR

cables.

2. Please see the other side of this manual for suggested

Mic Placement

.

Each

mic can be mounted on a mic stand with the built-in mount.

Depending on

the threading of your mic stand, you many need to remove the inner

threaded adapter.

Use a large flat screwdriver or coin to assist you.

3. Once the mics have been placed into position, you can turn the mixer ON

(make sure all volume, gain knobs, or faders on your mixer are turned OFF).

4. Bring the channel volume or fader up to 0 dB.

5. Play each drum individually and turn the mixer’s gain up on each channel

and stop just before the signal peaks.

This should be done at the loudest

volume you will perform at. Check for transients that can cause the signal

to peak and adjust your gain up or down as needed. It might be a good idea

to do a second signal check while playing the entire kit.

Drummers can

tend to play louder during a song with other band members playing along.

6. With the signal levels set, adjust any EQ that might be needed.

7. You are now ready to use your new

CM30D

mics.

CHECK LIST OF PARTS

Included with your

CM30D
