Main Specifications
 Receiving channels: Four channels (4 wireless handheld microphones or lavalier microphones)
 Chassis specifications: EIA standard 1U metal chassis
 Panel Display: Color VFD (vacuum fluorescent tube display) display, which can simultaneously display the band code, channel setting, RF/AF signal strength, automatic signal selection, noise interference and transmitter battery capacity. It can set multiple functions such as group, channel, frequency, user name, mute level, PC remote control address and panel lock.
 Carrier frequency band: UHF 620~934MHz
 Bandwidth: 24MHz
 Number of preset frequencies: Groups 01 to 06 each have 8 preset frequencies that do not interfere with each other without any restrictions, groups 07 and 08 each have 12 preset frequencies, and groups 09 and 10 each have 16 preset frequencies that do not interfere with each other, for a total of 104 carefully selected frequency combinations.
 Receiving mode: Dual tuner pure automatic selective reception
 Oscillation mode: PLL phase locked frequency synthesis
 RF stability: ±0.005% (-10~50℃)
 Practical sensitivity: S/N>80dB at an offset of 40KHz and an input of 6dBμV
 Maximum deviation: ±45KHz with volume expansion
 Overall S/N ratio:>105dB(A)
 Overall THD: <0.5% @ 1KHz
 Comprehensive frequency response: 50Hz~18KHz, with low frequency attenuation filter circuit
 Silent control mode: original "audio code and noise lock" dual silent control
 Volume output: The default setting is equal to the sound head sensitivity, and the user does not need to adjust the volume output.
 Maximum output voltage: Three-stage switch: balanced: +16dBV / 0dBV / -6dBV, unbalanced: +10dBV / 0dBV / -6dBV.
 Output socket: XLR balanced socket
 Output switching: can switch individual channels or mixed outputs
 Operation method: Manual adjustment and connection to computer remote control
 Mute adjustment: Use the front panel jog dial
 Mute adjustment display: Displayed by color VFD window option
 Power supply: Built-in 100~240V AC switching power supply
