Shure ULX ultra wide band UHF wireless systems. These systems are about 3-4 years old but were never used. I turned them on to verify they worked properly, mounted them in a rack and then never used them. My plans for them just never came about.
I have TWO of these systems. They come with dual antennas, user manuals, AC adapters, lavalier microphone (WL185), Beta 58A handheld microphone, ULX1-J1 transmitter and a ULXP4 receiver. An optional instrument cable can be purchased for them through Shure. Below the pictures (the second picture is a stock photo just to better show the receiver) is a complete list of features and specs.
These systems were $1100 brand new. I'm asking $400 a piece + shipping.
Features
Automatic Frequency Selection with group scan function
Over 1400 selectable frequencies
Predictive Diversity
5-segment transmitted audio signal strength meter
5-segment RF meter
3-segment transmitter battery fuel gauge
Advanced multi-function LCD displays group and channel
Mic/Line switch
Remotable 1/2-wave antenna
Frequency and volume lockout
XLR and 1/4-inch output
Rugged metal chassis
1/2 rack design
Specifications
RF Carrier Frequency Range: 554.000 to 865.000 MHz
Effective Range: 100 m (300 ft.) under optimal conditions (Actual working range depends on RF signal
absorption, reflection, and interference)
Audio Frequency Response: 25 to 15,000 Hz, (±2 dB (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 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
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 inch connector (into 3000
ohm load): —2 dBV
Impedance (output): 50 ohms at line level; 2000 ohms at mic level
Modulation: ±38 kHz deviation compressor-expander system with pre- and de-emphasis.
Dynamic Range: >100 dB, A-weighted
RF Sensitivity: 1.26µV 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: - 18 Vdc (negative ground), 550 mA
Battery Life: 8 to 9 hours (with 9V Duracell MN1604 alkaline battery)
Operating Temperature Range: -20 degrees to 49 degrees C (—4 degrees to 120 degrees F) NOTE:
Battery characteristics may limit this range.
Overall Dimensions: 1.72 in. x 8.56 in. x 6.52 in. (43 x 214 x 163 mm)
Net Weight: 2 lbs, 7 oz. (1105 g) |
