Passive selector with the convenient volume

If you do not hear an LP, this selector is a superior pre-amp of the cost performance.
There is not an amplifier function to this selector.
This selector without the phonoequalizer cannot use an LP player.
INPUT to connect CD Player, PC, tuner, TV, etc to has 3 circuits.

OUTPUT to connect power amp to has 2 circuits.
About OUT PUT, one and both output are possible.
Because you can connect two power amp, you output the same sound source in two rooms and can change it to one room.
Please control a sound source by the volume.

REC is not influenced by the volume.
REC outputs a select sound source directly.

I recommend that you connect the power amp of the high class to this selector than you purchase an expensive pre-amp.



How to choose volume resistance 10k and 50k

1) Please choose a 50KΩ type for vacuum tube power amplifier basically.
2) Please choose a 10KΩ type for transistor power amplifier.


Please be careful about the gain of the power amplifier.

High gain amplifier(recommended range between 0.1Volt and 1Volt) is desired because this device does not have booster circuit.
In the case the power amplifier gain is low, there is a possibility that output level is not enough.

Three points of support Metal Washers

wa01wa02

The materials are brass.

Entering 3

Product name "Metal Washer"

Usage:
Please exchange it for the rubber washer of the shell.
As for the general shell, a rubber washer is used for a connection point.
Because this rubber washer is tender, the point of contact makes it vague, slight movement occurs.
Three points of support metal washers lose the vague point of contact and use it to make it the point of contact that does not move.

wa03 => wa04 => wa05 => wa06
             
wa07 => wa08 => wa09 => wa10

An effect:
It can get a clear sound to get rid of the slight movement of an arm and the shell.
A careful sound and feeling of speed improve by getting rid of the vagueness of the point of contact by three projections of three points of support washers.
