Since 1987, the Corvette 50U-068S full amplifier has been produced by the Kirovsky Ladoga AOOT AOOT. '' Corvette 50-U-068C '' is a representative of a new generation of full amplifiers. In its creation, technical solutions of the amplifier `` Brig-001-stereo '' were used. For the first time, a LAN-class power amplifier with two-level power supply was used here, which made it possible to improve the thermal regime of the amplifier. UMZCH has protection against short circuit in load or during overload. There is a pickup switch with which, in addition to the electromagnetic, you can also connect the electrodynamic. The maximum power value is indicated by the indicator. The signal level limiter reduces the signal when using speakers with a power lower than recommended. A volume control with variable loudness allows you to reduce noise while lowering the volume level, and the choice of frequency response in the low frequency region matches the characteristics of auditory perception with the acoustic properties of the room. Interference at infra-low frequencies with EPIs is limited by the low-pass filter, and interference from phono records by the high-pass filter. Commutation of programs, speakers and headphones is made by push-button switches, with light indication. Switchable electronic output network allows you to power devices that work with the amplifier. Rated output power for speakers with an impedance of 8 (4) ohms 60 (80) watts. Operating frequency range 10 ... 70,000 Hz. Harmonic coefficient 0.05%. The coefficient of intermodulation distortion of 0.06%. The signal-to-weighted output noise ratio for PA is 96 dB. The dimensions of the amplifier are 430x390x120 mm. Weight 10.8 kg. The price is 650 rubles. The first releases of amplifiers were referred to as "Corvette U-068C" and "Corvette 50-068C." Since the beginning of 1989, the plant, together with the described amplifier, began production of the Corvette 100U-068S amplifier with a rated output power for an output of 8 (4) Ohms - 65 (95) Watt. ,null,ru,null,null,null,null
