话音控制增益自动调节恒量输出放大器(简称音控放大器)是近代短波无线电话终端设备的重要组成部分.这里所介绍的是用于发信支路的音控放大器(一般也可使用于收信支路),它的主要技术指标是:1.输入端电平变化-40～0分贝,输出端电平变化-1～+1分贝.2.频率响应在100赫至6千赫频段内,相对于1.5千赫变化约1分贝.
Voice control gain automatic adjustment Constant output amplifier (referred to as sound amplifier) is an important part of modern shortwave wireless telephone terminal equipment is introduced here is used to send the signal of the audio amplifier amplifier (generally also used for receiving branch Road), its main technical indicators are: 1. Input level changes -40 ~ 0 dB, the output level changes -1 ~ +1 dB. 2. Frequency response in the frequency range of 100 Hz to 6 kHz, the relative Changes at 1.5 kHz about 1 dB.
