Description

The PRO 23 is a cardioid instrument microphone featuring a low-proﬁle design for minimum visibility and versatile placement options.

Tailored for snare, toms and other highly dynamic instruments, the PRO 23 oers a moving coil dynamic design with cardioid polar pattern, delivering superior o-axis rejection for maximum gain before feedback. With a frequency response of 10012,000 Hz, the mic is engineered to handle fast transients and high SPLs.

The output of the microphone is a 3-pin XLRM-type connector.

The microphone is enclosed in a rugged housing and is outﬁtted with an integral ⅝"-27 threaded stand clamp. The included AT8665 drum mount screws into the stand clamp to permit mounting of the PRO 23 to the rim of a drum. A soft protective pouch is also included.

Operation and Maintenance

Output is low impedance (Lo-Z) balanced. The signal appears across Pins 2 and 3; Pin 1 is ground (shield). Output phase is “Pin 2 hot”— positive acoustic pressure produces positive voltage at Pin 2.

To avoid phase cancellation and poor sound, all mic cables must be wired consistently: Pin 1-to-Pin 1, etc.

Avoid leaving the microphone in the open sun or in areas where temperatures exceed 110° F (43° C) for extended periods. Extremely high humidity should also be avoided.

Take care to keep foreign particles from entering the windscreen. An accumulation of iron or steel ﬁlings on the diaphragm, and/or foreign material in the windscreen’s mesh surface, can degrade performance.
