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.
