distance as measured in free field shall be 394 ft. (120 m). The system shall be FCC and UL
listed with a five year manufacturer's warranty.

The wireless receiver shall have 16 selectable channels. The receiving method shall be double
super-heterodyne using antenna switching diversity. Specifications shall include a S/N ratio of
greater than 104 dB (A-weighted), harmonic distortion of less than 1% and frequency response of
100 - 12k Hz, ±3 dB. The receiving sensitivity shall be greater than 80 dB with 20 dBµV input and
40k Hz deviation. Squelch types shall be carrier and noise with a variable squelch sensitivity of 18

10k ohms and sensitivity of -20 dBV/100 mV shall allow the connection of the output of a second
receiver or other audio source to be mixed with the main receiver output signal. Front panel
LED's shall include AF PEAK that lights at 3 dB below clipping and ANT A/B. Front panel controls
shall include Check, Squelch and Volume. The wireless receiver shall be powered from the AC
mains using a supplied AC-DC adapter with a power consumption of 250 mA (12 VDC). The unit
shall operate within a temperature range of +14° F to +122° F (-10° C to +50° C). Unit
construction shall be black resin with dimensions of 9.45” x 1.38” x 4.33” (240 x 35 x 110 mm)

VAC, 60 Hz) and frequency-adjust screw driver.

The handheld wireless microphone transmitter shall have a cardioid pattern and be dynamic type
capable 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 ±40k Hz and a tone key frequency of 32.768k Hz. 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) diameter 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 (W x H x D) shall be 1.97"dia. x 9.26" (50 x 235.2
mm) for the dynamic handheld, 1.77" diameter x 9.26" (45 x 235.2 mm) for the condenser
handheld and 2.44” x 5.59” x 1.26” (62 x 142 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 condenser 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 lapel clip (lapel/bodypack). The aerobics
headset shall also include a sweatband and moisture-proof waist pouch.
