CAD Audio E300S Multi-Pattern Condenser Microphone User Manual

Introduction

Thank you for choosing the CAD Audio E300S Multi-Pattern Condenser Microphone. The E300S is a high-performance, externally-biased large-diaphragm condenser microphone designed for professional audio recording. Its versatile features, including multiple polar patterns, a hi-pass filter, and an attenuator, make it suitable for a wide range of applications, from vocal recording to instrument miking.

This manual provides detailed instructions to help you set up, operate, and maintain your E300S microphone, ensuring optimal performance and longevity.

Key Features

• Operating Principle: Externally-biased condenser for precise sound capture.
• Polar Patterns: Selectable Cardioid, Figure-of-Eight, and Omnidirectional patterns for versatile recording.
• Frequency Response: Wide range from 20Hz to 18KHz to capture full audio spectrum.
• High Sensitivity: -34dBV (20mV) @ 1 Pa for detailed sound reproduction.
• High SPL Capability: Handles up to 145dB SPL at 1% THD, suitable for loud sources.
• Attenuator: 20dB pad for managing high-volume inputs.
• Hi-Pass Filter: Reduces unwanted low-frequency noise.
• Power Requirements: P48 (48V) phantom power.
• Rechargeable NiMH Batteries: Provides current reserve for consistent performance.
• Included Accessories: Elastic shock mount and carrying case for protection and stability.

Setup Instructions

1. Unpack the Microphone: Carefully remove the E300S microphone and its shock mount from the carrying case.
2. Attach the Shock Mount: Securely screw the elastic shock mount onto a standard microphone stand. The shock mount helps isolate the microphone from vibrations and handling noise.
3. Mount the Microphone: Gently insert the E300S microphone into the shock mount. Ensure it is held firmly by the elastic bands.
4. Connect XLR Cable: Connect a balanced XLR cable to the microphone's XLR output connector located at the base. Connect the other end of the XLR cable to your audio interface, mixer, or preamplifier.

5. Apply Phantom Power: The E300S requires P48 (48V) phantom power to operate. Activate the 48V phantom power on your audio interface, mixer, or preamplifier. The microphone's internal rechargeable NiMH batteries provide current reserve, but external phantom power is essential for operation and to charge the internal batteries.
6. Position the Microphone: Place the microphone in the desired recording position, considering the sound source and the chosen polar pattern.

Operating Instructions

The CAD Audio E300S features several controls on its body to adjust its performance for different recording scenarios.

1. Polar Pattern Selection

The E300S offers three selectable polar patterns, allowing you to control the microphone's directionality and sensitivity to sound from different angles. Use the switch labeled with the polar pattern symbols.

• Cardioid (Heart-shaped symbol): Most sensitive to sound from the front, with significant rejection from the rear and sides. Ideal for isolating a single sound source, such as a vocalist or instrument, in a live or studio environment.
• Omnidirectional (Circle symbol): Equally sensitive to sound from all directions. Best for capturing ambient room sound, group vocals, or instruments where a natural, open sound is desired.
• Figure-of-Eight (Figure-8 symbol): Equally sensitive to sound from the front and rear, with strong rejection from the sides. Useful for recording two vocalists facing each other, or for capturing room reflections while minimizing side-bleed.

2. Hi-Pass Filter (Low-Cut Filter)

The hi-pass filter switch (often indicated by a sloped line symbol) reduces low-frequency content. This is useful for:

• Minimizing rumble from air conditioning, traffic, or stage vibrations.
• Reducing proximity effect (an increase in bass response when a sound source is very close to the microphone).
• Cleaning up vocal tracks by removing unwanted low-end mud.

Engage the hi-pass filter by moving the switch to the appropriate position (usually indicated by a sloped line or "HPF").

3. Attenuator (Pad)

The 20dB attenuator (often indicated by "-20dB" or "Pad") reduces the microphone's output level before it reaches your preamplifier. This prevents overloading the input stage of your mixer or interface when recording very loud sound sources, such as drums, guitar amplifiers, or loud vocals.

If you notice distortion or clipping in your recording chain, engage the 20dB pad by moving the switch to the "-20dB" position.

Maintenance

Proper care and maintenance will ensure the longevity and optimal performance of your CAD Audio E300S microphone.

• Cleaning: Use a soft, dry cloth to wipe the microphone body. Do not use liquid cleaners, solvents, or abrasive materials, as these can damage the finish or internal components.
• Storage: When not in use, store the microphone in its provided carrying case to protect it from dust, moisture, and physical damage. Avoid storing it in environments with extreme temperatures or high humidity.
• Handling: Always handle the microphone with care. Avoid dropping it or subjecting it to strong impacts, which can damage the delicate capsule.
• Phantom Power: Ensure P48 phantom power is consistently supplied during operation to power the microphone and maintain the charge of its internal NiMH batteries.
