Carvin cm98st User Manual

CARVIN ENGINEERING DATA

Congratulations on your purchase of the CM98ST tube microphone.  This

large diaphragm mic is a precision device that will provide accurate
recordings of vocals and instruments.  Stunning results can be acheived
from it’s wide-band fequency response and 6 micron edge terminated gold
sputtered diaphragm giving your recording a very warm, natural sound.
A special high pass filter eliminates unwanted low frequency rumble while
a -10dB pad switch prevents the diaphragm from being over-driven.  Enjoy
your new world of professional recording.

INSPECT YOUR MIC FOR ANY DAMAGE which may have occurred during shipping.  If any

damage is found, please notify the shipping company and CARVIN immediately. 

SAVE THE CARTON & ALL PACKING MATERIALS.  In the event you have to re-ship your

unit, always use the original carton and packing material. This will provide the best possi-
ble protection during shipment.  CARVIN and the shipping company are not liable for any
damage caused by improper packing.  

SAVE YOUR INVOICE.  It will be required for warranty service if needed in the future. 

RECORD THE SERIAL NUMBER on the enclosed warranty card or below on this manual for

your records.  Keep your portion of the card and return the portion with your name and com-
ments to us.

1. Plug the phantom power supply into the proper AC voltage.

2. With the power off, connect the gold 7-pin XLR mic cable to the MIC IN

on the power supply. 

3. With the Shockmount connected to a mic stand, thread your CM98ST

mic into the shockmount and connect the 7-pin XLR mic cable.

4. Next, you will need a second XLR cable (not included) to connect the

OUTPUT of the power supply to your input device (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 mixer are turned OFF).

6. Bring the mixer’s channel fader up.  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 the polar pattern and any EQ that might

be needed.  

10. You are now ready to record with your CM98ST mic.

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 CM98ST mic and the gold 7-pin XLR Mic Cable, phantom power
supply and a 120 V AC grounded power outlet.  You will also need a micro-
phone stand to attach the Shockmount to hold your CM98ST mic.  Other
equipment needed may include other cables to connect to a mixer or record-
ing device.
