Model Name: CHOIR STICK MI CROPHONE

Whenever possible, the distance from the mic to the rear­most pickup should be no more than twice the distance to
the front source, to maintain front-to-rear balance (Figure

1). Width of the pickup is approximately 2.5 times the
distance to the closest performer. If additional mics are
needed for wide sources, they should not be closer together
laterally than 2 to 3 feet, to avoid phase cancellation (Figure

2). This typical spacing is approximately 2.5 feet apart.
To orient the mic element in the proper direction, bend the
gooseneck housing until the desired location is found.

Note: All Shure

elements will have somewhat different

The Super-Cardioid Element (130°) configuration will have
a broader coverage pattern, leading to variations in the
distance to the front-most source, the angle of acceptance
(element polar patterns), and so

on. Since applications
may vary, please use this spec sheet as a guide. All draw­ings and measurements are for reference only.

CHOIR STICK MICROPHONE INSTALLATION
Ace Backstage Co.’s Choir Stick Microphone is a wide­range miniature condenser microphone designed for quality
sound reinforcement, professional recording, television, and
other demanding sound pickup applications. It requires
9V to 52 V DC from an external phantom power supply

(usually provided by the mixer). A recessed switch on
the power module permits the choice of flat response or
low frequency roll-off to help control undesired ambient
noise. Two interchangeable Shure

elements (Cardioid and

Super-Cardioid) are available to permit selection of angle
acceptance from 115° to 130°.

Note: Figures 1 and 2 assume that the element in place
is a Super-Cardioid element (115°). The combination of
small size and excellent response makes the Choir Stick
Microphone ideal for choirs, instrumental groups, or the­ater stages. A uniform 115° angle of acceptance from the
cardioid element provides well-balanced audio pickup. The
microphone should be located forward of the front-most
source (24”-36”) and above the rear most source (ap­proximately 24”-36”), and aimed between them (Figure

1). Increasing

the height of the mic above the sources will

tend to equalize the sound levels between them, but may
also increase the background/reverberant sound pickup.
