of a maximum input level of 130 dB SPL or electret
condenser type capable of a maximum input level of
125 dB SPL.The lapel microphone with bodypack
shall be electret condenser type with a cardioid
pattern and be capable of a maximum input level
SPL of 120 dB SPL.The headset (speech) microphone
with bodypack shall be electret condenser type with
a cardioid pattern and be capable of a maximum
input level SPL of 120 dB SPL.The headset (aerobics)
microphone with bodypack shall be electret
condenser type with a cardioid pattern and be
capable of a maximum input level SPL of 120 dB SPL.
The transmission method shall be frequency
modulation (F3E) with a PLL-based modulation
system operating in the frequency range of 692 -
722 MHz with 16 selectable channels.The RF carrier
power shall be no greater than 50 mW with
maximum deviation of ±40 kHz and a tone key
frequency of 32.768 kHz.The unit shall operate for a
minimum of 10 hours using a 9 V (6LR61), alkaline
type battery.A power LED shall glow continuously to
indicate normal operation and flash to indicate low
battery level (< 6 VDC).The transmitter shall utilize
a 1/4 wave helical antenna.Transmitter controls
shall include Power On/Off, Channel Select and Input
Sensitivity Adjust (bodypack).The bodypack shall
include a 0.14" (3.5 mm) dia.input jack and a
rotatable attachment clip.The transmitters shall
operate within a temperature range of +14° F to
+122° F (10° C to +50° C).The transmitters shall be
constructed of black resin. Dimensions shall be
1.97"dia. x 9.26" (50 mm x 235.2 mm) for the
dynamic handheld, 1.77" dia. x 9.26" (45 mm x
235.2 mm) for the condensor handheld and
2.44" W x 5.59" H x 1.26" D (62 mm x 142 mm x
32 mm) for the lapel and headset bodypack.The
lapel microphone cable length shall be 4.76 ft.
(1.45 m).The weight (with battery) shall be 0.60
lbs. (270 g) for the dynamic handheld, 0.55 lbs.
(250 g) for the condensor handheld and 0.33 lbs.
(150 g) for the bodypack. Included accessories shall
be a frequency-adjust screw driver and storage
case, stand adapter (handheld) and rotatable
lapelclip (lapel/bodypack).The aerobics headset
shall also include a sweatband and moisture-proof
waist pouch.
