ZS, LS, VS, WS Belt Pack

INSTRUCTIONS

The "ZS" Series:

A low profile microphone that has been developed especially for the flute family.   Most instruments have sound emanating out of more than one spot, the flute being no exception; that is why we use more than one microphone on one instrument: one over the keys, the second over the armature.  The volume of this mic positioned over the keys is balanced at 100% while the one at the armature is balanced at 75%.  This is to enable reproduction of the flute's natural sound.  The recommended placement is 3 1/2 - 4 inches over the keys for the first mic, and 1 inch away from armature for the second (see Figure 1).  When positioning the mic on the flute you may bend the flex part of the mic but never twist; this will damage the mic.  The microphone can be placed on the instrument by turning the thumbscrew counterclockwise until the jaws open enough to fit the clamp over the flute.  If at this point you have any reservations about scratching your flute we recommend making a sleeve out of felt and slipping it over the joint (see Figure 2).  Place the clip over the joint (or over the felt on the joint) and tighten thumbscrew tight enough so mic will not slide around.  If you your mic came with a belt pack, read on.

The "LS" Series:

A low profile microphone that can be used on most wind instruments with a flange on the bell.  It's supple gooseneck and harmonic dampener absorbs most of the handling noise that is produced by keys or valves.  It is important to realize the microphone is attached to the bell of the instrument, and it must be placed in an area that keeps it safe from impact by mutes, stands, etc.  The microphone can be placed on the instrument by holding the clip between the thumb and middle finger and pressing the button with the index finger.  The indentation in the clips should be placed on the flange of the bell.  At the end of the microphone wire is a 3.5mm plug which allows it to be used with the M-42 Belt Pack.

The "WS" Series:

A low profile dual microphone designed with bi-directional principles.  The four primary instruments are:  Clarinet, Oboe, Bass and Alto Flute.  To attach the microphone to Clarinet or Oboe first open the clamp to the full position by turning thumbscrew counterclockwise.  The clamp has been provided with rubber cushioning to prevent marring the instrument.  If at this time you are uncomfortable placing it directly on the instrument, we suggest making a sleeve out of felt, suede, leather, or flannel.  Place the clamp over the ring joint of the bell with the longest gooseneck of the microphone able the keys.  The smaller gooseneck can be placed above the bell, or moved up to the lower keys, or anywhere in between, for a specific sound desired,   It is important at this time that the balance of the microphone over the keys (long gooseneck) is set to 100% volume.  While the second microphone (shorter gooseneck) is set at 75% volume.

If used with Alto or Bass Flute, placement of clamp should be over the head joint.   If you have any reservations about placing it directly on the instrument, we suggest making a sleeve out of felt.  All other materials could damage the finish.   Placement of the longest gooseneck should be over the keys while the shorter should be aimed at the armature not to be in the direct path so as not to pick up wind noise.

The "VS" Series:

A low profile microphone designed for Violin and Viola.  This microphone incorporates a clamp that is adjustable for different widths of the Violin and Viola.   This can be achieved by loosening the set screw with the allen wrench that is provided.  Sliding the lip of the clamp to the width of the instrument.  The thumbscrew is used to apply pressure to the opposite side - to keep the microphone firmly placed on the instrument.  Allowing the user to decide how much tension they wish to apply.  The lips are fitted with soft suede to prevent marring the instrument.   If you are uncomfortable placing the microphone directly on the instrument at this time - we suggest soft material such as felt or chamois over the instrument where the clamp will be in contact.  Once you have the clamp open far enough to allow placement on the instrument turn the thumbscrew clockwise to apply pressure.  The supple gooseneck attaching the clamp to the microphone must be positioned in close proximity to the f-hole, but not point in.  Experimenting with placement will increase or decrease certain frequencies.

Caution:

It is important to realize when performing outside - the slightest breeze will create excessive noise.  A wind screen must be used in this situation.  We suggest using Windtec's model number 2100.  After use of the microphone it is important to keep it clean.  Using a soft brush remove any rosin or residue from the head of the microphone.  For the rubber gooseneck we suggest using a damp rag, or commercial product known as Armor All.
