Commentary

This is the first control amplifier under the new system.

We have adopted a unique matrix relay control, which is an extension of the conventional relay control method, to minimize the signal path and minimize the switch contact between any input and the main output to a maximum of two places.

The parts used are carefully selected from the highest quality parts including MIL standard.

The amplifier section (No26L) and the power supply section (PLS-226L) are separated to reduce mutual interference between circuits.
The internal structure is composed of two monaural preamplifiers in which the left and right circuits are completely independent, and the power supply section is composed of left and right independent components using a toroidal transformer.

It is equipped with an absolute switch for phase switching and a balanced output that enables high-purity signal transmission.

The basic model consists only of line amplifiers without phono amplifiers.
An optional slot on the main board allows you to add one of two types of phono cards (MC phono card and MM phono card) to create a model with a phono amplifier.
If you add a balanced input card instead of a phono card, you can change your existing line amplifier to a balanced input model.

Each additional card is equipped with a gain selector switch, and the phono card is equipped with an impedance selector switch. The combination of the gain selector switch and the left / right independent gain control on the front panel supports all inputs.
