Main Features • Broadband wireless receiver transmitter (50MHz), sub-receiver technology (25MHz two independent sub-bands of each): The receiver has two channels 100 channels adjustable independent, broadband transmitters can be common to both left and right sub-broadband, especially for a large number of places simultaneously. Solve the problem of string frequency. 100KTV rooms of different frequency, even more than 100 places, by different spatial multiplexing using the same frequency can easily deal with. • 1U metal chassis built-in dual-channel receiver circuit, a strong, heat-isolation and harmonic interference of professional quality. • with 『tone code and radio intensity』 mute control, prevention of karaoke machines, computers and DVD discs and other radiated noise interference. • ACT 』『 auto channel with the lock button to recover, as long as a press SET key, can make the transmitter auto lock receiver work channel error and failure. Specification Panel Display: LCD liquid crystal display, it can show RF / AF signal strength, channel, frequency, mute at the vibration mode of a number of functions: PLL frequency synthesizer phase-locked frequency stability: ± 0.005% (-10 ~ 50 ℃) Carrier frequency: UHF500 ~ 950MHz (Standard: 740 ~ 790MHz) Band width: 50MHz frequency adjustment: ∧ / ∨ select the desired frequency, press the SET 』『, can make the transmitter auto lock work channel of receiver. Receiving Mode: double-conversion receiver sensitivity: The degree of offset is equal to 40KHz, Input 6dBV time, S / N> 80dB maximum deviation: ± 68KHz with a volume extend S / N ratio:> 105dB (A) General THD: < 0.5% @ 1KHz Frequency response: 50Hz ~ 18KHz ± 3dB Maximum Output Voltage: Independent Balanced: +10 dB (2.5V) / 600Ω, unbalanced mix: +4 dB (1.25V) / 5KΩ. Mute Control: 『 tone code and radio intensity 』double mute control DC power supply: 12V/500mA
