Technical Info
Channel Frequencies
Channel J1: 554 to 590 MHz
Channel M1: 662 to 698 MHz
RF Carrier Frequency Range: 554.000 to 865.000 MHz (Available frequencies depend on the applicable regulations in the country where the system is used).
Effective Range: 100 m (300 ft.) under optimal conditions
Note: Actual working range depends on RF signal absorption, reflection, and interference
Audio Frequency Response: 25 to 15,000 Hz, +/-2 dB
Note: Overall system frequency response depends on the micro-phone element. *Output Level: Microphone Level = Line Level - 20 dB
Transmitter Audio Polarity: Positive pressure on microphone diaphragm (or positive volt-age applied to tip of WA302 phone plug) produces positive volt-age on pin 2 (with respect to pin 3 of low impedance output) and the tip of the high impedance 1/4 in. output
Transmitter Gain Adjustment Range: 25 dB
Receiver Audio Output Level (+/-38 kHz deviation, 1 kHz tone):
XLR connector (into 600 ohm load): +3.9 dBV (line), 17 dBV (mic)
1/4 in. connector (into 3000 ohm load): 2 dBV
Impedance
ULX1 (input): 1 Megohm
ULXS4, (output): 50 ohms at line level; 2000 ohms at mic level
Modulation: +/-38 kHz deviation compressor-expander system with pre- and de-emphasis.
RF Power Output: 30 mW maximum
Dynamic Range: >100 dB, A-weighted
RF Sensitivity: 1.26 uV for 12 dB SINAD (typical)
Image Rejection: 80 dB typical
Spurious Rejection: 75 dB typical
Ultimate Quieting (reference +/-38 kHz deviation): >105 dB, A-weighted
System Distortion (reference +/-38 kHz deviation, 1 kHz modulation): 0.3% total harmonic distortion, typical
Power Requirements
ULX1: 9V alkaline battery (Duracell MN1604 recom-mended); 8.4V Nicad optional
ULXS4: 14 - 18 Vdc (negative ground), 550 mA
Battery Life: 8 to 9 hours (with 9V Duracell MN1604 alkaline battery)
Operating Temperature Range: -20 to 49 C (+4 to 120 F)
Note: Battery characteristics may limit this range.
Overall Dimensions
ULX1 (H x W x D): 96.5 x 67 x 26.7 mm (3.86 x 2.68 x 1.10 in.)
ULX4S (H x W x D): 43 x 214 x 163 mm (1.72 x 8.56 x 6.52 in.)
Net Weight
ULX1: 79 g (2.8 oz.), without battery
ULXS4: 1049 g (2 lbs, 5 oz.)
