Product Details
Features
√ The number of four channel groups: 8 zones, each zone has 100 frequency points, and the frequency points do not interfere with each other, so multiple machines can be used at the same time.
√ Using the latest type of high-frequency acoustic surface filters to maximize the filtering of out-of-band interference signals.
√ Using double frequency conversion high frequency circuit design, with extremely high sensitivity.
√ Voice compression and expansion circuit, greatly improve the signal to noise ratio, unique voice compressor design.
√ Has a lockable control function button, easy to operate.
√ Equipped with independent adjustment of electronic volume for each channel.
