Condenser Microphone

Thank you for choosing the MXL 770 Condenser microphone. With proper care, this mic will provide many years of satisfaction. To get the best results, please take a few moments to read this manual. Enjoy your microphone!

The MXL Team

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 subtle sonic details. They also tend to pick up sounds outside the pattern more than some designs, which can lead to powerful feedback if you are not careful. We strongly advise experimentation with placement and isolation requirements with the gain initially set low to avoid equipment (and ear) damage. It is strongly advised to use a mesh pop-filter to avoid moisture from damaging the capsule.

Contents

Unpack your MXL 770 microphone carefully and verify that all of the following items are included:

MXL 770 microphone • Shock mount • Carrying case

If any of these items are missing or damaged, contact the company from which you purchased the microphone.

Bass roll-off switch

The 770 features a bass roll-off switch to help reduce proximity effect. Proximity effect is distortion that often occurs when a sound source is too close to the mic. Some microphone patterns boost bass as you get closer to the micro-Phone; cardioid mics, for instance, tend to boost bass. The bass roll-off switch reduces the low frequencies for a more full range sound.

-10DB Switch

The 770 can be used in very loud sonic environments without significant distortion. If you hear distortion from the microphone, engage the "-10dB pad" on the rear of the microphone to the -10dB position. You may also move the microphone farther away from the sound source.

Power Requirement

The MXL 770 requires 48V phantom power ( ± 4V). If no sound is picked up by the microphone, make sure that the phantom power on your mixer or separate power supply is switched on.

Microphone Cable

The microphone cable can have a profound effect on the sound of any microphone. Even the finest microphone will sound poor if the interconnect cable allows noise to enter or causes distortion and loss of information. We recommend that you use the best microphone cable that your budget will allow.

Care

Dust and foreign material can reduce the performance of a microphone over time, so you should store the MXL 770 in its case when not in use.

Shock Mount

The MXL shock mount can shift in shipment. Simply shift the nylon bands to center the microphone in the assembly. Be sure that the wire clamp does not rest on the chassis of the mount, as this impairs mechanical isolation. Slide the mount all the way to the rim of the microphone for the most secure hold.
