Sennheiser MD 735
A supercardioid vocal dynamic that Sennheiser built around a suspended capsule and a glass-composite body, then advertised with a fold-the-page gimmick.
Overview
The MD 735 is a dynamic microphone with a supercardioid polar pattern and a frequency response of 50-18,000 Hz. Sennheiser sold it as part of its ProForce line. According to EQ-Magazine (October 1995, p.20), that line had its roots in an older Sennheiser favorite. That is the magazine's own framing, and it suggests the MD 735 was positioned as a vocal workhorse rather than a ground-up design. Sennheiser recommended it specifically for lead vocals.
The engineering fits that job. The capsule is suspended and isolated to cut down handling noise, which helps when a singer grips the body and moves around a stage. The housing is a durable glass-composite. Behind the diaphragm sits an NdFeB magnet structure that EQ-Magazine (October 1995, p.20) notes allows for a high output voltage. Sensitivity is listed at 2 mV/Pa, with an electrical impedance of 350 ohms. That is higher than the 200-ohm nominal impedance Sennheiser used on some of its other dynamics, so check how a given preamp or console input reacts before assuming plug-and-play behavior.
Compared with a plain cardioid, a supercardioid rejects more from the sides, at the cost of a lobe directly behind the mic. That makes stage placement and monitor positioning matter more than the spec sheet suggests.
