Thank you for purchasing the MXL Recording Pac Plus. Your purchase includes the MXL 2003 studio recording
microphone and the MXL 603 instrument microphone. With proper care, these mics will provide many ye ars of
satisfaction. For best results, please take a few moments to review this literature.
MXL 2003 Studio Recording Microphone
General Characteristics
This microphone has a 1.06” gold-sputtered diaphr agm and a very open and unconstrained cardioid pickup pattern.
Large capsule condensers are very sensitive, readily revealing ver y subtle sonic details. They also tend to pick up
sounds outside the pattern more than some designs, which can lead to po werful feedback if you are not careful. We
strongly advise experimentation with placement and isolation requirements with the gain initially set low
equipment (and hearing) damage!
Power Requirements
IMPORTANT - This unit requires phantom power at 48 volts, +/- 4 volts. Each unit has been thorough ly c hecked before
shipping, so if you do not hear sound, check that the phantom power on your mixer or separate power supply is
switched on!
Isolation Shockmount
The high-isolation shockmount may shift during ship ping. S imply shift the elastic bands t o cent er the microph one in th e
assembly. Be sure that the wire clamp does not rest on the chassis of the mount, as this im pairs mechanical isolation.
Slide the mount all the way to the rim of the microphone grill for the most secure hold.
Microphone Cables
The microphone cable can have a profound effect on the s ound of any microphone. Even the finest microphon es will
sound poor if the interconnect cable allows nois e to enter, or causes distortion and loss of information. Use only the
best microphone cable your budget will allow.
Care
Dust and foreign material can degrade the performance of a mi crophone over time so alwa ys store the unit in its case.
For vocals closer than 3”, use a “popper stopper” or a foam windscreen to avoid g etting moisture on the diaphragm as
this can substantially degrade the microphone’s performanc e. Store the microphone in its original packaging in a co ol,
dry place.

MXL 603s Instrument Condenser Microphone
General Characteristics
This microphone has a twenty millimetre gold-sputtered diaphragm and a fixed cardioid pickup pattern. Condenser
microphones are very sensitive, readily revealing very subt le sonic details. They also tend to pick up sounds outside
the pattern more than some designs, which can lead to po werful feedback if you are not careful. We strongly advise
experimentation with placement and isolation requirements with the gain initiall y set low
to avoid equipment (and ear)
damage!

before shipping, so if you do not hear sound, check that the phantom power on your mixer or se parate power supply is
switched on!
