Description
 
Control amplifier equivalent to No. 1 under a new system.

The relay control by the original matrix scheme into which the system for change-over by an old relay system was developed further is adopted. The switchpoint electric contact point between all inputs and main outputs is suppressed to a maximum of two places at the same time it makes a signal path into the shortest by this.

The part of the highest peaks including Military Standard is selected carefully and adopted as a using part.

The cross interferencee is suppressed by having the stream composition which separated the amplifier part (No26L) and the power-source part (PLS-226L).
The internal structure has two monophonic preamplifier composition which became independent completely in the circuitry on either side, and the right-and-left independent stream composition which used the toroidal transformer is adopted as a power-source part.

The absolute switchpoint for a phase switching and the balance output which makes signal transmission of a high purity possible are carried.

The stream composition of only line amplifier without phone amplifier is made into the basic model, and the option slot prepared on the mainboard is used,It is possible to constitute a model with phone amplifier from adding one of two kinds of phone cards (MC phone card / man-month phone card). Moreover, if a balance input card is added instead of a phone card, the existing line amplifier can be changed into the model used as the type corresponding to a balance input.
The gain changeover switch is prepared in these cards, respectively, and the impedance changeover switch is also carried in the phone card. All the inputs are supported with the combination of the right-and-left independent gain control on this gain changeover switch and the front panel.
