PRE4562 - AUDIO LINE PREAMPLIFIER - PROGRAMMED SYSTEM
Producer: AVT
The audio line preamplifier with the signal input switch is an indispensable element of any amplified amplifier circuit. The described project is equipped with a relay (PVC) volume control eliminating problems with modern potentiometers and remote control to improve service while maintaining the simplest possible system solutions. Thanks to the use of modern elements, a very decent result can be achieved with a small cost.
Recommendations: a complete preamplifier with a source selector that is useful, for example, in a built-in power amplifier.
Basic parameters:
