Convenient voluminous passive selector without power supply
If you dont use a record, this is a cheap and very good preamp. There is no amplifier and there is no amplifier function. Record players cannot be used without a phonoequalizer
There are 3 inputs of 1, 2, and 3 to connect audio from CDs, computers, tuners, and TVs.
The output (OUTPUT) connected to the power amplifier has two types of A and B, allowing you to output both A and B simultaneously by switching between A and B.
Recording terminal (REC) can record signals selected by SELECTOR 1, 2, and 3, regardless of volume position.
In addition, if you want to adjust the volume and want to record recording, please use OUTPUT A or B.
Rather than spending money on expensive preamps, you can upgrade the power amplifier by using a cheap selector.
You may see preamplifiers with expensive transformers and expensive volume resistors, but we didnt want to improve sound quality as much as the price. This selector is not inferior to those premium products.
How to choose the type (how to choose the volume resistance).
Please choose the standard 50KΩ type for vacuum pipe power amplifiers, and 10KΩ type for transistor power amplifiers.
