Product Details:

   Acoustic system equipment main technical indicators frequency characteristics: Audio equipment playback frequency range (frequency response) and signal amplitude with the change of frequency. Amplitude-Frequency characteristics: The unit of magnitude is db, and the frequency unit is Hz. Audio Guide System Equipment The frequency response of the sound system equipment is at least 32-18000hz, and the amplitude of the signal should be less than 2dB in this frequency range. Signal-to-noise ratio: The logarithm of the ratio of useful signals to noise at the same reference point. In the speaker input point signal-to-noise ratio 70dB, the human ear distance speaker a meters noise is almost not audible, fi system generally reach more than 100dB.

Dynamic range: The logarithm of the ratio of the maximum output power to the system noise output when the audio equipment is replayed. Audio Guide System Equipment Fi system generally reach more than 100dB. Distortion: The distortion of the sound source signal when reproducing audio equipment. Harmonic distortion, intermodulation distortion, transient distortion. Fi system harmonic distortion is generally less than 1%. Stereo separation: The separation of left and right two channels. Reflects the crosstalk level between the left and right channels. Stereo Balance: The difference between the signal gain of the left and right channels.

Sound system equipment is good or bad often need to look at some parameters below are some of the main technical indicators复件 Tour guides with MIC and earphone.jpg

Main technical specifications of sound system equipment

Frequency characteristic: The frequency range (frequency response) and the change of signal amplitude with frequency when reproducing audio equipment.

Amplitude-Frequency characteristics: The unit of magnitude is db, Audio Guide System Equipment and the frequency unit is Hz. The frequency response of the sound system equipment is at least 32-18000hz, and the amplitude of the signal should be less than 2dB in this frequency range.

Signal-to-noise ratio: The logarithm of the ratio of useful signals to noise at the same reference point. In the speaker input point signal-to-noise ratio 70dB, the human ear distance speaker a meters noise is almost not audible, Audio Guide System Equipment fi system generally reach more than 100dB.

Dynamic range: The logarithm of the ratio of the maximum output power to the system noise output when the audio equipment is replayed. Fi system generally reach more than 100dB.

Distortion: The distortion of the sound source signal when reproducing audio equipment. Harmonic distortion, intermodulation distortion, transient distortion. Audio Guide System Equipment Fi system harmonic distortion is generally less than 1%.

Stereo separation: The separation of left and right two channels. Reflects the crosstalk level between the left and right channels.Rose red.jpg

Stereo Balance: The difference between the signal gain of the left and right channels.
