Features:
1). Frequency: 2400-2483MHz.
2). More than 20 channels for selection.
3). Input interface is compatible with both microphone and stereo audio input, and can be shift without turning the device down.
4). Digital transmission.
5). Additional 20dB selection available for the microphone input (for the high-sensitivity microphone, monitoring applications).
6). Highest sampling ratio in the field:
64k@16bit x 2, with the frequency response of 20-20KHz, HDCD sound quality.
7). Small in size, highly integrated.
8). Lowest latency in the field (<0.5ms), excellent surrounding effect.
9). Low power consumption, wide range of input voltage.
10). Audio muting function when receiving weak or no signals.
11). Auto channel scanning function.
12). The receiver has the special function of standby dormancy when there is no signal, and the standby current is less than 0.5 mA.
13). For headphone users, there's a low work voltage (2-2.2 V) in option.
14). Channel LCD display screen.
15). Flexible design ability to support customized functions.
16). Transmitting output power: 0-20 dBm at your option (to be confirmed in the order); Transmitting range can be up to 180 meters in an open field with the highest output power.
