Onkyo P-308

This control amplifier is designed to provide serious digital support and simplify high purity transmission. Direct In - We intend to take direct out thoughts and adopt simple circuit configurations that are multi-functional. Line-type inputs such as CD inputs are selected by the Input Selector switch, then then directly to the master volume-flat amplifier through muting, balance volume, mode and more. In addition, the tone control uses a direct tone system that is composed of a passive element by using a part of the volume circuit, eliminating the amplifier for toning. In addition, direct wiring is thoroughly conducted at the shortest distance between the input and the output side. Equipped with 8 input selectors and a separate double REC selector for Tape1 only. It has two outputs and a MODE switch on each one so you can get outputs for 3D subwoofer or center channel playback. The Output2 also includes an independent output attendant for both the left and right balance volume. The circuit configuration uses a super servo amplifier configuration with twin FET input and twin push-pull output stages. In addition, it achieves excellent characteristics by injecting the beneficial LED bias in terms of temperature coefficient and generated noise, as a material that obtains a constant voltage of about 2 V at a relatively small current.
