Low frequency amplifier "Impulse-80".

Amplifying and broadcasting equipmentThe LF amplifier "Impulse-80" was produced presumably since 1978 by the Kherson semiconductor device plant. Designed to amplify low-frequency signals from microphones, electric guitars, electric organs, synthesizers, tape recorders and other sources. Designed to work in pop music ensembles. The device consists of a monophonic bass amplifier with a mixer of six channels in one case, has three microphone inputs, two inputs for connecting electric guitars and one for connecting an electric organ. For each of the 6 first inputs, volume control is provided, as well as the timbre for the highest and lowest sound frequencies. There is an output to the effects "loop" with level control and two outputs to the speaker systems. The amplifier is equipped with electronic protection against short circuit of the load, there is an overload indicator that allows you to monitor the mode of its operation. The amplifier was produced in two versions of external design and with two speakers (2 types). The nominal output power of the amplifier is 75 W into a load of 6 ohms. Maximum output power 150 watts. The nominal frequency range of the amplifier is 30 ... 20,000 Hz. SOI 1%. Tone control range ± 12 dB. Power consumption no more than 300 watts.
