Notes:

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

• 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.)
Dynamic range: 90 dB (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).

Power requirements

Normal operating voltage: 1.5 V DC
Minimum operating voltage: Approx. 1.1 V DC
