PRODUCT INFORMATION - OPUS 54
Thank you for selecting the Opus 54 neckworn microphone. Please
take some time to read carefully through this product information
before setting up the equipment.
Application
The Opus 54 has been designed for "hands free" applications. It is
ideal for sales and product seminars, workshops, entertainers, dancers,
drummers, keyboard players etc. Due to its low profile the Opus 54 is
also suited for aerobics instructors, theatre use and stage musicals.
Connection
Three versions of the Opus 54 are available for use with wireless belt-
pack transmitters: The Opus 54.100 is equipped with a 3.5 mm mini
stereo Jack plug, the Opus 54.16/3 is fitted with a 4-pin Lemo plug
and the Opus 54.18 comes with a 4-pin mini XLR plug. The Opus
54.09 has a bare-ended cable.
For wired applications with phantom power sources the Opus
54.16/3 can be used with the CV 3 adapter. If the CV 3 is completed with
the ZCV battery compartment, the Opus 54 can also be used battery
powered (9 V).
Setting up and adjustment
The Opus 54 features a rugged yet adjustable neckband and flexible
ear bows that can be shaped for personal comfort to ensure a secure
fit. The Opus 54 is also suited for people who wear glasses.
The Opus 54 has a cardioid polar pattern which means a high gain
before feedback can be achieved, it also helps eliminate background
noise.
The flexible gooseneck allows optimum positioning of the micro-
phone and due to the angled form of the microphone it can be
placed to the side of the mouth for maximum intelligibility. Avoid
continuous bending of the gooseneck as it can cause excessive stress
and wear out the gooseneck.

Maintenance

Use a soft, damp cloth for cleaning the Opus 54 microphone and
connecting cable. If necessary, you can use a gentle cleansing agent
(such as washing-up liquid). Make sure not to allow any water to enter
the transducer element and never use any solvent cleansers.
If you use the Opus 54 with a pop screen, you should clean it in clear
water from time to time. Make sure the pop screen is completely dry
before it is replaced back onto the microphone.
Service
Servicing must be carried out by qualified service personnel only.
Dismantling the microphone yourself will invalidate the guarantee.
