Radius 200M is an easy-to-use UHF True Diversity instrument wireless system that provides reliable, crystal-clear sound for the most demanding professional applications. Alto’s True Diversity receiver design is absolutely state-of-the-art. Radius 200’s True Diversity system improves upon the Radius 100, because it utilizes two separate receiver sections as well as two antenna systems. The unit constantly polls both receivers and the signals at the antennae, to instantly and seamlessly select the stronger signal. This is what “bulletproof” wireless performance sounds like.FeaturesAll-in-one, easy-to-use instrument wireless system for the most demanding professional applicationsDual-antenna/dual-receiver True Diversity design for mission-critical, dropout-free operationUHF band operation (520 - 937.5MHz) regionally selectedReceiver includes a high-visibility back-lit LCD display: Displays RF frequency and channel, AF and RF signal levels and other critical functionsWireless belt-pack transmitter and 1/4-inch instrument cableSingle-button scan feature for quickly identifying the optimal operating frequencySync function automatically synchronizes transmitter and receiver frequencySquelch control for maximum clarity and dynamic rangeFront-panel rotary volume controlBalanced XLR and unbalanced 1/4 -inch mic or line-level outputsSpecs RECEIVERUHF Band Operation: 520–937.5 MHz (region-specific)Oscillator: PLL SynthesizedFrequency Stability: ±0.005%Modulation: FMTransmission Range: 328 feet / 100 metersSignal-to-Noise Ratio: > 100 dB (at 20 KHz deviation and 60 dBV antenna inputImage & Spurious Rejection: 80 dB minimumReceiving Sensitivity: At 2 uV over 52 dB/A SNRSelectivity: > 50 dBAF Response: 80 Hz – 18 KHzTHD: < 1% (at 1 KHz)IF Frequency: 1st: 243.95 MHz / 2nd: 10.7 MHzDynamic Range: > 100 dBTone Signal: 32.768 KHzAudio Output: 1 balanced XLR1 unbalanced 1/4” (6.35mm)Display: High-visibility back-lit LCD with RF and AF metersPower: Supply: 12 V, 1 A, center positive (adapter included)Consumption: 520 mA ±10 mACase: Half 19” EIA-rack metal caseDimensions: 7.9” x 7.2” x 1.720.0 cm x 18.3 cm x 4.2 cmWeight: 2.1 lbs.1.0 kgTRANSMITTERSUHF Band Operation: 520–937.5 MHz (region-specific)Channel Selection: Synchronization with receiverRF Power Output: 10 mW (maximum)Frequency Stability: ±0.005%Deviation: ±20 KHz with limiting compressorSpurious Emission: > 60 dB below carrier frequency.
