Purpose of the development: Multichannel automatic level control beep "Audio ALC-16" equipment designed for base stations and microwave cable television and performs the function of leveling sound signals at the input channel modulators.

Recommended application field: Telecommunication systems and television.

Technical characteristic: 1. Nominal input and output levels - 0 dB ( 0.775 V RMS with a load of 600 ohms). Provided the initial output level adjustment with an error less than 0.5 dB. 2 . Effectiveness of automatic level control : when the average input level of -20 dB to +3 dB output level varies no more than -6 dB to 1 dB. Dependence of the average output level of the input is a piecewise linear function of the three areas - gain limit . 3 . Operating frequency - 20 Hz -20 kHz ( -3 dB) 40 Hz -15 kHz (1 dB). 4 . THD at input level : minus 20 dB less than 0.2% , 0 dB is not more than 0.25% , +3 dB - less than 0.5% . 5 . Squelch threshold trigger level at the entrance - from -50 dB to -40 dB ( optimum value favorites for experimental operation ) . 6. Power supply voltage - 220 V ± 10% 50 Hz. Power consumption - no more than 10 VA .

Advantages over analogues: Additional function of "Audio-ALC-14" compared to the "Audio-ALC-16" is the possibility of introducing an external audio signal in all channels - for ads, etc.

The development stage readiness: Introduced in production

Description of the development:
()
The device allows you to eliminate unwanted sound level differences between different channels as well as between the different gears and advertising inserts within a single channel. To connect an external audio ads has a separate entrance and exit through ( for distribution to the following blocks). The signal from any possible announcement unit. To receive and normalization of the external signal applied ads AGC circuit similar to the main channels. Device implementation on TV " ZHMITS - TV network " Zhitomir , LLC " Lviv - KTB " TRK " Detinets " Chernigov .
