Wireless microphones hold the promise of freedom from restrictive cables and the ability to closely connect with your audience—whether that audience is a throng of concert attendees, an all-important business group or a crucial phone caller in an urgent situation. These are the times when rock-solid dependability matters above all else. The Radius 200 utilizes Alto Professional’s most sophisticated diversity system, a cutting-edge system called True Diversity. Alto’s True Diversity receiver design is absolutely state-of-the-art. True Diversity system improves upon Radius 100’s Diversity system 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 microphone performance sounds like.FeaturesAll-in-one, easy-to-use wireless microphone system for the most demanding professional vocal applicationsDual-antenna/dual-receiver True Diversity design for mission-critical, dropout-free operationUHF band operation: 520 - 937.5MHz (regionally selected)Receiver includes a high-visibility back-lit LCD display: Displays RF frequency and channel, AF and RF signal levels and other critical functionsSingle-button scan feature for quickly identifying the optimal operating frequencySync function automatically synchronizes transmitter and receiver frequencySquelch control for minimizing background noise during silent periodsFront-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 frequencyDisplay: Hand-Held Microphone: 2-digit 7-segment LCDBelt-Pack Transmitter: 2-digit 7-segment LCDPower: Hand-Held Microphone: 2.4 VDC (1.2V via 2 AA batteries)Belt-Pack Transmitter: 3 VDC (1.5V via 2 AA batteries)Consumption: 120 mA 10 mADimensions:Hand-Held Microphone: 2.0” x 2.0” x 10.2” / 5.2 cm x 5.2 cm x 26.0 cmHeadset Microphone: 1.5” x 0.5” x 0.5” / 3.8 cm x 1.3 cm x 1.3 cm avalier Microphone: 1.0” x 0.25” x 0.25” / 2.5 cm x 0.6 cm x 0.6 cmBelt-Pack Transmitter: 2.6” x 3.8” x 0.9” / 6.5 cm x 9.7 cm x 2.4 cmWeights:Hand-Held Microphone: 0.5 lbs. / 0.2 kg Headset Microphone: 0.2 lbs. / 0.1 kg Lavalier Microphone: 0.1 lbs. / 0.05 kg Belt-Pack Transmitter: 0.2 lbs. / 0.1 kg.
