CM98ST Large Diaphragm Tube Condenser Mic
OPERATING MANUAL
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.

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.
