Six-channel audio preamplifier with common volume control
Spilka, Benedikt ; Balík, Miroslav (referee) ; Hanák, Pavel (advisor)
The main aim of this bachelor thesis is to design and to construct a low-frequency six-channel preamplifier with remote and local control and with symetric and line input for up DPA223 low-frequency amplifier. The preamplifiers must have galvanic separation together. Its gain/amplification must be remote controllable from mute to 0dB and locally from 0dB to -20dB. Low distortion, noise and other parameters monitored in audio technics are important for the design.
