Digital Hybrid Wireless Belt-Pack Transmitters
Rio Rancho, NM
25
Transmitter
Operating Frequencies:
Band A1: 470.100 - 537.575
Band B1: 537.600 - 614.375
Band C1: 614.400 - 691.175
Frequency Selection Steps: Selectable; 100 kHz or 25 kHz
RF Power output: 25, 50 or 100 mW
Pilot tone: 25 to 32 kHz; 5 kHz deviation
(Digital Hybrid mode)
Frequency Stability: ± 0.002%
Deviation: ± 75 kHz max. (Digital Hybrid mode)
Spurious radiation: 60 dB below carrier
Equivalent input noise: –120 dBV (A-weighted)
Input level: Nominal 2 mV to 300 mV, before limiting
Greater than 1V maximum, with limiting.
Input impedance: • Mic: 300 Ohm
• Line: 2k Ohm
Input limiter: DSP controlled, dual envelope “soft” limiter
with greater than 30 dB range
Gain control range: 44 dB; digital control
Modulation indicators: • Dual bicolor LEDs indicate modulation of
-20, -10, 0 and +10 dB referenced to full
modulation
• LCD bar graph
Controls: Side panel membrane switches with LCD
interface for power on/off and all setup and
configuration controls
Audio Input Jack: Switchcraft 5-pin locking (TA5F)
Audio Performance (Digital Hybrid mode)
Frequency Response:
Mic input: 35 Hz to 20 kHz (+/-1dB); low frequency
roll-off is selectable at 35, 50, 70, 100, 120, 180 Hz
Line/Instrument: 35 Hz to 20 kHz (+/-1dB)
THD: 0.2% (typical)
SNR at receiver output:
Note: The dual envelope “soft”
limiter provides exceptionally good
handling of transients using variable
attack and release time constants. Once activated, the limiter compresses 30+ dB
of transmitter input range into 4.5 dB of receiver output range, thus reducing the
measured figure for SNR without limiting by 4.5 dB
SmartNR No Limiting w/Limiting
OFF 103.5 108.0
NORMAL 107.0 111.5
FULL 108.5 113.0
