Wireless microphone system with LINE 6 XD-V55(12ch) and a SHURE lavalier microphone. The transmitter is V55-BP(12ch). Since the microphone is SHURE, I think the sound quality is better than the original (subjective...). This SHURE microphone (unidirectional) was opened for photography, but is new and unused. I have confirmed that power, channel settings, and sound output all work normally. ■ Digital wireless set ideal for performers and vocalists who require professional quality ■ Can be used worldwide without a license ■ Equipped with unique EQ filter modeling technology that allows performers to select the appropriate model depending on the microphone placement and the instrument being connected ■ 12 channels can be used simultaneously ■ Operates on the 2.4Ghz band, free from interference from TV broadcasts, white space devices, and cell towers ■ 90m transmission range ■ One-step setup ■ The bodypack LCD displays the selected channel, battery life, EQ filter model, etc. ・ Specifications ■ Frequency band: 2.4Ghz ISM band ■ Simultaneous channels: 12 ■ Frequency response: 10 Hz (-0.5dB) - 20kHz (-2.5dB) ■ System latency: Less than 2.9 msec (from audio input to output) ■ THD: 0.03% typical ■ Operating temperature: 1-50℃ ・ Receiver ■ Number of receiver antennas: 2 ■ Power requirements: 9Vdc 500mA ■ Output impedance: XLR / 150Ω balanced, 1/4 inch / 1kΩ unbalanced ・ Transmitter ■ RF output power: 10mW ■ Maximum audio input level: 6.5Vpp ■ Input impedance: 1.3MΩ ■ Supply bias voltage: 5VDC ■ Included accessories: AC adapter, Tokunashi lavalier microphone, transmitter V55-BP, 1/2 wavelength antenna x 2 Thank you for viewing.
