Miyajima Passive Selector

If you do not listen to LPs, this selector is the best performing passive “pre-amp” for the money.
There is no amplification in this passive “pre-amp” input selector.
This passive “pre-amp” input selector does not have phono equalization and cannot be used to play LPs!
There are three stereo input circuits; connect any high output devices such as CD player, tuner, TV or PC.

There are two stereo OUTPUT circuits to connect to power amplifiers.
You may connect either of the output pairs or both pairs simultaneously.
Because you can connect two power amps, you can send the same sound to either one, or two rooms. Please – always turn down the volume control before switching to a different input source.

REC output is fixed and not changed by the volume control.
REC output jacks connect to the input source directly.

You can connect a high quality amplifier to this passive “pre-amp” input selector and volume control chassis rather than purchase an expensive preamplifier; the only input source that won’t be available directly is for phono /LPs.

How to choose the volume control resistance (10k or 50k)
1) Please choose a 50KΩ resistance type for vacuum tube power amplifiers.
2) Please choose a 10KΩ resistance type for transistor power amplifiers.

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.
