Cardioid Dynamic Microphone

The e 604 is a compact cardioid dynamic for close proximity drum and percussion use.

The mic features a reinforced glass-fiber body, hum compensating coil, and integral stand mount.

The 604 frequency plot shows significant proximity effect at 5cm, which is the mic’s intended use distance: measured at its intended pos - approx +9dB @ 85Hz. High mids are emphasized, +3dB from 3–5kHz, with a flat high end through 15kHz and a rapid dropoff in response above ~16kHz.

Although described as a Cardioid microphone, the polar plot reveals a wide-cardioid response below 2kHz, with significant loss of rear rejection at low frequencies. Above 2kHz, the pattern is Supercardioid. At 16kHz, the pattern narrows significantly, with 25dB of rejection past 60° off-axis.

The e 604 ships with a drum rim mount and storage pouch. It is available singly, in 3-packs, and as part of the Drum Kit 600 microphone set (see sidebar link).

The Sennheiser Electronics Corporation e 604 is also known as: e604, evo604.
