SLX Wireless Systems feature the patented Audio Reference Companding for crystal-clear sound beyond the limits of conventional wireless technology. Automatic Frequency Selection Automatic Transmitter Setup 960 Selectable frequencies across 24 MHz bandwidth Detachable 1/4 wave antennas Microprocessor-controlled diversity RF presence LED 5-segment audio meter Multi-function, backlit LCD Low battery indicator Frequency and power lockout Rugged metal chassis Volume control on rear of unit 1/2 rack design Furnished rack hardware Non-slip bumpers for use out of rack XLR and 1/4" outputs Dimensions 42 mm H x 197 mm W x 134 mm D (1.65 x 7.76 x 5.28 in.) Weight 816 g (1 lb. 13 oz.) Housing Galvanized steel Audio Output Level (ref. +/– 38 kHz deviation with 1 kHz tone) XLR connector (into 600 Ω load): –13 dBV 1/4 inch connector (into 3000 Ω load): –2 dBV Output Impedance XLR connector: 200 Ω 1/4 inch connector: 1kΩ XLR output Impedance balanced Pin 1: Ground Pin 2: (+) Pin 3: (-) Sensitivity –105 dBm for 12 dB SINAD, typical Image Rejection >70 dB, typical Power Requirements 12–18 Vdc at 150 mA, supplied by external power supply Operating Range Under Typical Conditions 100m (300 ft.) Note: Actual range depends on RF signal absorption, reflection, and interference Audio Frequency Response (+/– 2 dB) Minimum: 45 Hz Maximum: 15 kHz Note: Overall system frequency depends on microphone element. Total Harmonic Distortion (ref. +/– 38 kHz deviation, 1 kHz tone) 0.5%, typical Dynamic Range >100 dB A-weighted Operating Temperature Range –18°C (0°F) to +50°C (+122°F) Note: battery characteristics may limit this range Transmitter Audio Polarity Positive pressure on microphone diaphragm (or positive voltage 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. Beta 58A® Vocal Microphone The Beta 58A microphone accentuates the warmth and clarity of lead and backup vocals. Its supercardioid design provides maximum isolation from other onstage sounds. Supercardioid, Dynamic Frequency response: 50 to 16,000 Hz Neodymium magnet for high signal–to–noise output SLX2 Handheld Transmitter Frequency response: 50 to 15,000 Hz Automatic Transmitter Setup Backlit LCD with timeout feature 470 - 782 MHz operating range
