MARCAD (MAximum Ratio Combining Audio Diversity)circuitry constantly monitors signals from both receiver sections and combines them to create a single output signal. The result is improved reception and exceptional freedom from dropouts.
The LX4 receiver interfaces with the HR (half-rack) format, and are supplied with both single and dual rack-mount hardware. An optional WA503 accessory kit lets you front-mount antennas.
The LX2 transmitter includes a three-light gauge that indicates both “power on” and the amount of battery life remaining.
Instead of a conventional single RF meter, the LX4 receiver has two meters, one for each antenna. The dual meters indicate received signal strength at each antenna, and make it easier to identify and troubleshoot RF “deadspots.”
A five-light audio meter helps to optimize transmitter gain setting and lets you monitor audio level during operation.
Guitar players demanding the highest degree of sound quality and reliability will appreciate the low noise and uncolored sound of the LX Wireless System.
This circuit analyzes signal quality instead of signal strength. This virtually eliminates the possibility of annoying noise bursts coming through your receiver.
The supplied ac power adapter incorporates small, in-line transformers that save space on ac power strips. It also has mounting tabs so it can be secured to any surface, as well as locking dc power connectors to prevent accidental disconnection from the receiver.
|RF Carrier Frequency Range||169.445 to 240.000 MHz (available frequencies depend on the applicable regulations in the country where the system is used)|
|Working Range||91 m (300 ft) under typical conditions. NOTE: Actual working range depends on RF signal absorption, reflection and interference.|
|Audio Frequency Response||50 to 15,000 Hz, ±2 dB. NOTE: Overall system frequency response de-pends on the microphone element.|
|Audio Output Level(±15 kHz deviation, 1 kHz tone)||XLR connector (into 600 Ω load): 0 dBV (line), –20 dBV (mic)1/4inch connector (into 3 kΩ load):–8.8 dBV|
|Gain Adjustment Range||25 dB|
|Impedances||Output: 150 Ω (XLR); 3 kΩ (1/4-inch phone jack)|
|Modulation||±15 kHz deviation compressor-expander system with pre- and de-emphasis|
|RF Power Output||50 mW maximum (complies with FCC and IC regulations)|
|Dynamic Range||>102 dB, A-weighted|
|RF Sensitivity||0.45 μV for 12 dB SINAD (typical)|
|Image Rejection||80 dB typical|
|Spurious Rejection||75 dB typical|
|Ultimate Quieting (ref. 15 kHz deviation)||>100 dB, A-weighted|
|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.)|
|System Distortion (ref. ±15 kHz deviation, 1 kHz modulation)||0.3% THD typical|
