Audio-Technica ES925Cx/DS3 Modular Gooseneck Condenser Microphone

Introduction

Thank you for purchasing this product. Before using the product, read through the user manual to ensure that you will use the product correctly. Please keep this manual for future reference.

Features

• Modular microphone system comprised of an ES Series capsule, gooseneck assembly, and power module.
• RGB LEDs built into both the desk stand power module and gooseneck assembly indicate the on/off status of the microphone.
• The capacitive touch switch can be set to any of three operating modes: "touch-on/touch-off", "touch-to-talk" and "touch-to-mute".

Safety Precautions

Although this product was designed to be used safely, failing to use it correctly may result in an accident. To ensure safety, observe all warnings and cautions while using the product.

Cautions for the Product

• Do not subject the product to strong impact to avoid malfunction.
• Do not disassemble, modify or attempt to repair the product.
• Do not handle the product with wet hands to avoid electric shock or injury.
• Do not store the product under direct sunlight, near heating devices or in a hot, humid or dusty place.

Notes on Use

• Do not swing or pull the product. Doing so may cause disconnection or damage.
• The circuitry in the microphone takes about 30 seconds to stabilize after power is supplied. You may hear some audio disturbance during startup.
• The connectors are equipped with a special RFI-shielding mechanism. If you remove or replace the connector, you may adversely affect the microphone's RFI immunity. The Audio-Technica Crimp Tool (ATCT) and shield parts are required to shorten the cable and reinstall the connector while maintaining the RFI immunity.
• Install the microphone on a flat, unobstructed mounting surface. Make sure that the sound source is not below the mounting surface.
• Depending on the surface finish of a table, the desk stand power module may leave marks on the table.
• Do not excessively bend the gooseneck assembly, rotate the ends of the capsule, or pull on them. Doing so may cause disconnection or malfunction.
• The product is a modular system comprised of a microphone element, gooseneck assembly and power module. Make sure the parts are firmly attached before use.
• Do not remove the rubber O-ring on the power module connecting part at the lower section of the gooseneck assembly.
• When attaching parts, remove the black cap on the capsule connecting part of the gooseneck assembly. Do not remove the silicone part at the end of the capsule connecting part.

Switch Settings

To reduce low-frequency ambient noise (such as footsteps or air conditioning noise), room reverberation, and mechanically coupled vibrations as much as possible, turn on the low-cut filter switch [low-cut filter switch] on the bottom of the power module.
