USING YOUR DM-90

The DM-90 can be used with any standard mixer, powered mixer/ amplifier, or mic preamp. Using either an XLR to XLR or XLR to 1/4" phone plug low impedance cable, connect the female XLR end to the DM-90 and the other end (male XLR or 1/4" phone plug, as appropriate) to your equipment.

The DM-90 can be mounted on a microphone stand with the integral mic holder mount supplied. Depending on the threading of the mic stand you are using, you may need to remove the threaded adapter from the mic holder.

Be aware of the proximity effect (an increase in bass response) when the mic is placed close to the instrument. This may or may not be desirable. Experimenting with the position of the mic with respect to the audio source will ensure the optimum results you are seeking in any given application.

If the microphone is placed too near a speaker during live stage use, an unpleasant howling effect (acoustic feedback) may occur. Although all microphones are prone to feedback to some extent, with a unidirectional polar pattern are specially designed to accept only signals from the audio source directly in front of the mic cartridge. Thus, the cardioid pattern of the DM-90 ensures that it will deliver only the desired audio in front of the mic, rejecting the unwanted audio from the rear, even in noisy ambient conditions with high sound pressure levels from the P.A. and monitor speakers. This means that feedback will be greatly minimized with the DM-90 in all live performance miking applications.

Some useful ways in which to totally eliminate annoying feedback include: experimenting with mic positions with respect to the speakers, decreasing speaker volume (whenever possible), and adjusting the equalization of the mic audio with the mixer.
