User Manual
HYPERCARDIOID CONDENSER
MODULAR GOOSENECK MICROPHONE
WITH 3-PIN FLUSH-MOUNT POWER MODULE
■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 flush-mount power module and gooseneck
assembly indicate the on/off status of the microphone.
• Capacitive touch switch for microphone control.
• Three-pin output power module allows for inconspicuous tabletop installation.
■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
• Check the strength of the mounting area. Insufficient strength or poor
mounting will cause objects to fall or become damaged.
• The circuitry in the microphone takes about 30 seconds to stabilize after power
is supplied. You may hear some audio disturbance during startup.
• Install the microphone on a flat, unobstructed mounting surface.
• Depending on the surface finish of a table, the isolators 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.

■Assembly
• Insert the gooseneck assembly (c) while rotating it into the flush-mount power
module (d).
• Tighten until it does not rotate, and use the hex wrench (i) to tighten the set
screw (h) and set the gooseneck assembly in place.
• Connect the capsule (b) to the gooseneck assembly, and attach the windscreen
(a).
* If the parts are not sufficiently tightened together, problems may occur such as
the LED colors of the gooseneck assembly and power module not matching or
sound is not output.
• Refer to the LED table to the right and set the LED color before attaching to
the mounting surface.
• If you are installing the flush-mount power module on a table without the
isolators, you must make a hole with a diameter of 20.5 mm in the mounting
surface.
• If you are installing with the isolators, the hole must have a diameter of 23.5
mm. Inserting the isolators between the mounting surface and power module
allows you to separate the flush-mount power module from the mounting
surface.
• Attach the upper part isolator (e) to the mounting surface, and attach the flush-
mount power module (d). Attach the lower isolator (f) to the reverse side of the
mounting surface, and then tighten the nut (g).
