Place the microphone 3-5 cm above the head, at an angle of 30-60° for optimal balance between fundamental and harmonics.

How to avoid interference from other sound sources?

Position the microphone so that the off-axis source is in the maximum attenuation angle, approximately 120°.

What accessories are included with the E904?

The microphone comes with a MZH 604 clamp, a pouch, and the user manual.

Can I use the E904 on a guitar amplifier?

Yes, the E904 is suitable for miking guitar amplifiers, as well as percussion, brass, and woodwinds.

What is the polar pattern of the E904?

The E904 has a cardioid polar pattern, which allows focusing on the source while attenuating side and rear noise.

What is the frequency response of the E904?

The frequency response is 40 to 18 000 Hz, providing a powerful and lively sound on drums and percussion.

How to clean the E904 microphone?

Use a dry, soft cloth to clean the housing. Avoid solvents or abrasive products.

What type of connector does the E904 use?

The E904 features a XLR-3 connector rotated by 90°, reducing space, especially with angled connectors.

Is the E904 suitable for vocals?

No, the E904 is primarily designed for instruments (drums, percussion, amplifiers). For vocals, prefer the e935 or e945 models.

USER MANUAL E904 SENNHEISER

Instructions for use

Notice d'emploi

High-quality dynamic microphone with cardioid pick-up pattern.

Due to its compact design, the microphone is ideal for use with drums (toms and snoares). It can easily be positioned in cramped space conditions (e.g. below the cymbals) and the supplied MZH 604 microphone clamp allows to precisely attach it to the rim of the instrument.

The 904 is also suitable for miking guitar amplifiers, percussions as well as brass and woodwind instruments.

A rugged full metal body effectively protects the microphone from impact damage.

The XLR connector turned by 45^ allows the space saving positioning of the microphone in the case of angled connectors.

Features

• Extremely vivid, powerful sound with drums and percussions
  Sound can be shaped as needed to fit all styles of music
• Extremely rugged for rough stage use
• Hum compensating coil protects against electromagnetic interference
  Gold-plated XLR connector (turned by 45^ )

Positioning the microphone

Drums

Position	Resulting sound	Commentary
	More fundamental tone, little overtones	Position on the drum: 3–5 cm above the batter head, the fundamental tone to overtones ratio can be adjusted via the angle. The most balanced results are obtained at an angle of 30–60°.
	Less fundamental tone, many overtones
		Use of a second €904 for picking up the resonant head and the snares. If necessary, activate phase reversing for one of the microphones.

In order to prevent interference due to crosstalk between adjacent sound sources, try to position the microphone so that the interfering sound source is located in the angle area of the highest cancellation of the microphone (approx. 180^ ).
