ITC - T-531B, Wireless Microphone

Characteristics

- It adopts 1/2 width and 1U height of EIA international standard metal cabinet, which can be directly mounted to the rack.

- With 100 frequencies in each of 640-857MHZ six frequency bands, advanced PLL frequency synthesis phase-locked loop technology, adjustable frequency and adjustable transmit power to avoid interference frequency.

- Superior anti-interference ability can effectively restrain same frequency interference, or noise caused by the external interference.

- LCD display window, channel, frequency, RF signal strength, AF audio output intensity.

- With infrared frequency automatic synchronization locking transmitter frequency ACT function.

- Receiving antenna adopts rear separated design, single-antenna automatic selection reception, audio code and noise to lock double mute circuit. It is not only long in receiving distance, but also rare to disconnect.

- SQ internal adjustment can increase the receiving sensitivity to increase the receiving distance, or reduce the sensitivity to avoid noise interference.
