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).
Refer to the frequency supplement supplied with the system.

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 microphone 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 voltage on pin 2 (with respect to pin 3 of low impedance output) and the tip of the high impedance 1 / 4 -inch output

Transmitter Gain Adjustment Range ULX2: 25 dB

Receiver Audio Output Level (+/-38 kHz deviation, 1 kHz tone):
XLR connector (into 600 ohm load): +3.9 dBV (line), -17dBV mic
� in. connector (into 3000 ohm load): -2 dBV

Impedance: ULXS4 (output): 50 ohms at line level; 2000 ohms at mic level

Modulation:
+/-38 kHz deviation compressor-expander system with pre- and de-emphasis

FR Power output: ULX2: 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:
ULX2: 9V alkaline battery (Duracell MN1604 recommended); 8.4V Nicad optional
