Radio constructor `` Start-7235 '' (Block audio frequency amplifier).
Radio and electrical constructors, sets.Audio AmplifiersThe radio designer "Start-7235" (Block Amplifier of ZCh) has been produced possibly since 1989. A high-quality block stereo amplifier can be assembled from RC, consisting of a pre-amplifier (UP) and a power amplifier (PA). The end-to-end operating frequency range is 20 ... 30,000 Hz. The input voltage of the UP - 0.25 V, the UM - 1 V. The harmonic coefficient at the rated output power of the UE - 0.2%, the UM - 0.3%. The nominal output power of the PA is 2x12 W, the maximum is 2x25 W. The PA has an LED indicator of peak output power values with indication of 2, 4, 8, 12 and 16 W for each channel. Dimensions of any UP or UM unit - 300x230x75 mm. Unit weight - 2 kg, UM - 4.5 kg.
