How should I position the ISOMAX 4RF for best coverage?
The ISOMAX 4RF’s extremely accurate hypercardioid pattern works best when the mic
element is about a foot in front of the presenter and at chest level, pointing toward the face.
This location eliminates pops and other breath noises, doesn’t interfere with sight lines, and
accommodates both normal conversational levels and presenters who prefer to project to
the crowd.
The pickup area is approximately a 90° cone extending from the tip of the microphone,
allowing the presenter to move around or share the podium with a second person.
ISOMAX 4RF Podium: Frequently Asked Questions
12”
What options are available for the ISOMAX 4RF?
The most popular conguration is black, with an 18” semi-rigid stalk that is exible at the top
and bottom. The ISOMAX 4RF is supplied with a matching windscreen and storage tube.
Length:
Stock lengths are 12”, 18”, and 24”, including the microphone capsule and connector base.
Rigidity:
The ISOMAX 4RF stalk is available exible; semi-rigid with a exible top, bottom, or top and
bottom; and completely rigid. The semi-rigid section can be bent without tools. The exible
sections are easily adjusted by the presenter.
Special orders:
The ISOMAX 4RF can be special ordered in cardioid, hypercardioid, or omnidirectional
patterns.
How should I mount the ISOMAX 4RF to a desk or podium?
The Countryman A4CDM Desk Mount is specically designed for the ISOMAX 4RF
microphone. It consists of a Neutrik connector module and a metal bushing that can be
mounted through a table top or podium surface. It both supports and connects the mic, and
provides an attractive, unobtrusive mount with a very small footprint. This kind of mounting
is practical only because of the ISOMAX 4RF’s Active Vibration Isolation—other podium
microphones require bulky shock mounts to avoid table vibration noises.
Mounting the A4CDM requires drilling the table surface and soldering to the connector
module, and is recommended for permanent installations only. The mic itself is held in
place by the XLR connector’s latch and can be easily removed for storage.
