• Always handle the microphone with care to prevent damage to the sensitive capsule.
• Ensure the microphone is securely mounted on a stand using the provided shockmount to avoid accidental drops.
• The U 87 Ai requires 48V phantom power. Connect it only to equipment that provides standard phantom power.
• മൈക്രോഫോണിനെ തീവ്രമായ താപനില, ഉയർന്ന ഈർപ്പം അല്ലെങ്കിൽ നേരിട്ടുള്ള ഈർപ്പം എന്നിവയ്ക്ക് വിധേയമാക്കുന്നത് ഒഴിവാക്കുക.
• Do not attempt to open or service the microphone yourself. Refer all servicing to qualified personnel.
• ശക്തമായ കാന്തിക മണ്ഡലങ്ങളിൽ നിന്ന് മൈക്രോഫോൺ അകറ്റി നിർത്തുക.

Carefully remove the microphone and its accessories from the wooden box. Inspect all components for any signs of damage.

2. Mounting the Microphone

Attach the EA87 shockmount to a suitable microphone stand. Gently insert the U 87 Ai microphone into the shockmount, ensuring it is held firmly but without excessive force. The shockmount helps to isolate the microphone from vibrations transmitted through the stand.

3. മൈക്രോഫോൺ ബന്ധിപ്പിക്കുന്നു

Connect the provided XLR cable to the 3-pin XLR connector at the base of the microphone. Connect the other end of the XLR cable to a microphone preamplifier, audio interface, or mixing console that supplies 48V phantom power. Ensure phantom power is turned off on your device before connecting or disconnecting the microphone to prevent potential damage.

1. Polar Patterns

The U 87 Ai offers three selectable polar patterns: omnidirectional, cardioid, and figure-8. These patterns determine the microphone's sensitivity to sound from different directions.

• ഓമ്നിഡയറക്ഷണൽ: Picks up sound equally from all directions. Ideal for capturing room ambiance or multiple sources.
• കാർഡിയോയിഡ്: Most sensitive to sound from the front, with significant rejection from the rear. Suitable for vocals and isolating individual instruments.
• ചിത്രം-8: Equally sensitive to sound from the front and rear, with rejection from the sides. Useful for recording two vocalists facing each other or for M/S stereo techniques.

The polar pattern switch is located on the front of the microphone body, below the grille.

2. Pre-attenuation Pad (-10dB)

The U 87 Ai features a switchable -10dB pre-attenuation pad. This pad reduces the microphone's output level by 10 decibels, preventing distortion when recording very loud sound sources, such as close-miked drums or guitar amplifiers. Engage this switch when the input signal is too hot for your preampജീവൻ.

3. Low-Frequency Roll-off

A switchable low-frequency roll-off (high-pass filter) is integrated into the U 87 Ai. This filter attenuates frequencies below approximately 100 Hz, which can be useful for reducing unwanted rumble, handling noise, or proximity effect when close-miking. The switch for the low-frequency roll-off is typically located near the polar pattern and pad switches.

4. ഒപ്റ്റിമൽ പ്ലേസ്മെന്റ്

Microphone placement significantly impacts the recorded sound. Experiment with distance and angle relative to the sound source to achieve the desired tonal balance and minimize unwanted room reflections. For vocals, a pop filter is recommended to reduce plosives.

• വൃത്തിയാക്കൽ: Use a soft, dry cloth to wipe the microphone body. Do not use liquid cleaners or solvents, as they can damage the finish or internal components.
• സംഭരണം: When not in use, store the microphone in its original wooden box or a protective case to shield it from dust, moisture, and physical impact.
• കൈകാര്യം ചെയ്യൽ: Avoid dropping or subjecting the microphone to harsh impacts. The capsule is a delicate component.
• പരിസ്ഥിതി: Operate and store the microphone in a clean, dry environment with stable temperature and humidity.
