Description: LEIXEN N8 LCD Display Portable 1MHz-1000MHz Frequency Counter CTCSS / DCS Frequency Counter for Walkie Talkie Features: N8 handheld frequency counter using dot-matrix LCD, it mainly used to measure the frequency, CTCSS and DCS of radio transmission. The counter has antenna to make measurement quick and convenient. Specification: Operating current: 46mA Battery: 3-1.5V AAA Batteries Color: Camouflage / Yellow / Black Measure range: Frequency 1MHz-1000MHz, all CTCSS, all DCS Operation: P ower On/OFF: Press the power button and release to power on. Press the power button and hold 2 seconds to power off. M easure Method: a. Press the power button to turn on the counter, put the signal source nearby the counter, the measured frequency will be displayed within 1 second. (Sometimes there is a frequency value on the screen already when the counter power on, that is an interference frequency. You should press the power button once after put the signal source nearby the counter, and then the value is measured.) b. If the signal source has a CTCSS tone, the tone will be showed directly below the transmitted frequency display. c. If the signal source has a DCS code, the normal code and the invert code of DCS are simultaneously showed directly below the transmitted frequency display. (The DCS measurement would take one second more time.) d. To measure again, press the power button. T est measurement results: To test the results, press the right M button, the counter will transmit a low level signal with a tone. Your receiver will hear this so you know that the tested frequency and tone is correct. A utomatic power off: In the absence of any operating system would power off automatically after 60 seconds.

  The P Audio PHT-404 is an integrated high frequency horn and compression driver. The design yields very extended high frequency response and controlled directivity in a rectangular geometry. The rated coverage pattern is100 degree horizontal by 60degree vertical. This rated coverage pattern is ideal for short throw applications such as foreground and background music system designs found in restaurants, pubs, and retail environments. The PHT-404 has a rated bandwidth of 3kHz to beyond16kHz. This frequency response range makes the system excellent for wide coverage upper midrange and high frequency operation. The PHT-404 is ideally mated with a 10inch, or 8 inch low frequency loudspeaker in a two way design. The PHT-404 features a 1 inch diameter (25.4mm)phenolic based diaphragm assembly. The small format (1inch diaphragm is ideal for maintaining piston range performance in the upper frequency range. The wide horizontal mouth (10.6inches,269mm) maintains very good horizontal coverage control. The high sensitivity of 105dB (1watt at 1meter) allows the PHT-404 to be used in medium sized venues. The horn is made of a rigid die cast aluminium and the critical compression driver components are all controlled by P Audio’s advanced quality and manufacturing systems.

You can use it for your home stereo, then remove it and insert it into your cars audio system, for music on the go.This product takes up little space measuring in at just 8.5 centimeters with a weight of 25 grams. Investing in a good audio isolator such as this will not only cancel ground loop noise, but will also play your music without any unwanted distortion. The low frequency of this HIFI version isolator can reach 20hz, allowing for 99% of consumers to receive distortion free audio. Features The low frequency of this HIFI version isolator can reach 20hz,audiophile should know the meaning of it. Because the human hearing range is from 20hz to 200000hz, people will not hear distortion Effectively filters the distortion out of the audio in your car, or on your home stereo. Easy to use. Just plug it in and begin enjoying perfect audio. Employs proprietary audio transformers for a dB gain of 1.3 Included connectors: 3.5mm Male to 3.5mm Female hookup Rids your speakers of any humming/buzzing related to ground loop issues Passive in-line device Gets rid of DC current in the way of the signal path Complete frequency response Features a close to perfect audio response of +/- 0.0 dB from 20-20,000 Hz This islator only can cancel ground loop noise,For example; if you hear a noise when charging your device but not when operating on battery, then this product should solve the problem. This package includes: o 1 Kript Ground Loop Noise Isolator o 1 Instruction Manual for ease of use
