Frequency response

Directivity

Before operating the unit, please read this manual thoroughly. This manual should be retained for future reference.

For the customers in Europe

This product is intended for use in the following
Electromagnetic Environments: E1 (residential), E2 (commercial and light industrial), E3 (urban outdoors), E4 (controlled EMC environment, ex. TV studio).

ATTENTION
The electromagnetic fields at the specific frequencies may influence the sound of this unit.

FEATURES

• Compact and lightweight design allows unobtrusive microphone use.
• Omni-directional directivity allows clear sound pickup from any direction.
• Powering system using an internal battery.
• Easy handling carrying case.

PRECAUTIONS

• The microphone should never be dropped or subjected to any excessive shock.
• Keep the microphone away from extremely high temperatures (above 60°C or 140°F)
• If the microphone is used too close to speakers, the sound from the speakers will be picked up and produce a howling effect (i.e., acoustic feedback). To prevent howling, avoid facing the microphone toward the speakers and maintain as much distance from the speakers as possible.
• Microphone and recording instruments should be turned on 10 minutes before they are actually used. This assures stable performance of the microphones and instruments.

BATTERY OPERATION

1. Open the battery compartment by turning the sleeve counterclockwise.
2. Insert an IEC designation R6 or LR6 (size AA) battery into the battery compartment.
   
   
3. Close the compartment by turning the sleeve clockwise. Be sure to close the sleeve firmly, otherwise malfunction or noise may occur due to the loose fit.

Notes:

• If the microphone is not to be used for a long time, remove the battery to avoid any possibility of corrosion.
• In case of battery leakage, wipe off any deposit in the battery compartment.
• Battery life depends on the battery type being used. Refer to the "Battery life" in "Specifications" below. When the battery is exhausted, sensitivity will be decreased and distortion will be heard. When this occurs, replace with a new battery.

CONNECTIONS

The output connector of the microphone is the XLR3-12C type. Connect the microphone plug to the microphone input of a mixer or a tape recorder. The microphone cable is 3 m (10 feet) long.

If a longer cable is necessary, an extention cable up to 200 m (660 feet) may be used without affecting sound quality or performance. Use a cable with an XLR-3-11C connector at one end and an appropriate plug at the other end which matches the input equipment.

Note:
If cable connector connection is necessary, note that there are two basic types of connections, balanced to ground and unbalanced to ground, and solder connections carefully. Poor soldering may cause hum pick up.

MORE ABOUT MICROPHONE USE

• To reduce the effect of wind or breath noise, attach the supplied wind screen to the microphone.
• The supplied microphone holder is convenient for attaching the microphone to clothing. Be careful not to cover the microphone head.

Performance

Frequency range: 40 Hz–15,000 Hz
Directivity: Omni-directional
Output impedance: 250 ohms ±20% (1 kHz), balanced
Sensitivity (typ.): –53 dB (2.2 mV) (0 dB = 1 V/Pa, 1 kHz)
Signal-to-noise ratio: 62 dB (typ.) (IEC 179 A-weighted, 1 kHz, 1 Pa)
Inherent noise: 32 dB SPL (typ.) (0 dB = 2 × 10^–5 Pa)
Wind noise*¹: Less than 40 dB SPL (with wind screen)
Maximum input sound pressure level *²: 122 dB SPL (typ.)

Operating temperature: 0°C to 60°C (32°F to 140°F)
Storage temperature: –20°C to +60°C (–4°F to +140°F)

*1 Value derived by applying a wind velocity of 2 m/sec. (6.6 ft./sec.) to the microphone from all directions, and converting the mean value to the equivalent input sound pressure level (0 dB = 2 × 10^–5 Pa).

*2 Value derived by taking the input level at which 1% waveform distortion occurs with a 1-kHz microphone output signal, and converting it to the equivalent input sound pressure level (0 dB = 2 × 10^–5 Pa).
