ApplicationSuggested Microphone Placement Tone Quality Kick Drum 5 to 7.5 cm (2 to 3 in.) away from beater head, slightly off-center from beater. Sharp attack; maximum bass sound, highest sound pressure level.

Medium attack; thin, re- duced bass sound. 5 to 7.5 cm (2 to 3 in.) away from outside head, on-axis with beater (dou

MOUNTING THE BETA 52A ON A MICROPHONE STAND The builtin stand adapter features a dynamic locking system that permits adjustments to the microphones position, but resists slipping when struck or bumped. To mount the BETA 52A on a stand and adjust its position, proceed as follows: Screw the
12、integral stand adapter onto the end of a micro- phone stand (see Figure 3). Adjust the stand height and position as necessary. Pivot the BETA 52A until it is in the desired position rela- tive to the drum head or loudspeaker. Lock the BETA 52A in place by rotating the adjustment knob on the stand ad
13、apter clockwise until it is tight. Do NOT overtighten the knob with tools. If necessary, make minor adjustments to the microphone position without loosening the adjustment knob. Connect an audio cable to the integral XLR connector. 1. 2. 3. 4. 5. MODEL BETA 52A RadioFans.CN 收音机爱 好者资料库 2 SPECIFICATIO
