Frequency-Agile UHF Belt-Pack Transmitter
Rio Rancho, NM
15
The FCC requires that the following statement be included in this manual:
This device complies with FCC radiation exposure limits as set forth for an uncontrolled environment. This device
should be installed and operated so that its antenna(s) are not co-located or operating in conjunction with any
other antenna or transmitter.
Operating frequencies:
Block 470 470.100 - 495.600
Block 19 486.400 - 511.900
Block 20 512.000 - 537.500
Block 21 537.600 - 563.100
Block 22 563.200 - 588.700
Block 23 588.800 - 607.900 and
614.100 - 614.300
Block 24 614.400 - 639.900
Block 25 640.000 - 665.500
Block 26 665.600 - 691.100
Block 27 691.200 - 716.700 (export only)
Block 28 716.800 - 742.300 (export only)
Block 29 742.400 - 767.900 (export only)
(Frequency usage varies by country
Frequency Selection: 256 frequencies in 100 kHz steps

Compatibility Modes: Lectrosonics Digital Hybrid (400 Series), 200 Series, 100 Series, and IFB.
Mode 3, Mode 6 (Other brands).
RF Power output: 50 mW
Pilot tone: 25 to 32 kHz frequency; 5 kHz deviation (400 Series only)
Frequency stability: ± 0.002%
Deviation: ± 75 kHz max. (200 & 400 Series Modes)
Spurious radiation: 60 dB below carrier
Equivalent input noise: –120 dBV, A-weighted
Input level:
If set for dynamic mic: 0.5 mV to 50 mV before limiting.
Greater than 1 V with limiting.
If set for electret lavaliere mic: 1.7 uA to 170 uA before limiting.
Greater than 5000 uA (5 mA) with limiting.
Line level input: 5.0 mV to 6 V before limiting.
Greater than 15 V with limiting.
Input impedance:
Dynamic mic: 300 Ohms
Electret lavaliere: Input is virtual ground with servo adjusted
constant current bias
Line level: 2.7 k Ohms
Input limiter: Dual envelope, >30 dB range
(Note: The dual envelope “soft” limiter provides exceptionally good handling of transients using variable attack and release time constraints.)

Instrument Cable: –12 dB/octave; -3 dB @ 35 Hz
Audio frequency response (overall system): Microphone : 90 Hz to 20 kHz (+/- 1 dB) with the 70Hz low frequency roll-off filter.
Instrument Cable : 40 Hz to 20 kHz (+/- 1 dB)
Controls: 2 position “OFF-ON” slide switch for noiseless turn on/turn off operation.
Front panel audio gain control.
Rotary switches on side panel adjust transmitter frequency.
Audio Input Jack: Switchcraft 5 pin locking (TA5F)
Antenna: Galvanized steel, flexible wire.
Battery: Precision compartment auto-adjusts to accept any known alkaline 9 volt battery.
Battery Life: 6 hours (alkaline); 7 hours (LiPolymer); 13 hours continuous (lithium)
Weight: 6.3 ozs. including battery
