GENERAL INFORMATION

Dynamic Precision BPC 7.3.

We congratulate you on your choice of the

The technical solutions are all based upon the best high quality switches, connectors and discrete

components available, and the company's unique knowledge to achieve the best possible reproduction of

musical signals.

power amplifiers is designed to accommodate passive balanced configurations by

keeping the input capacitance between 100 pF and 200 pF (please consult the Users Guide for that

particular power amplifier). As a result of this, the cable length between

and the power amplifier

can be extended compared to other power amplifiers normally having a higher input capacitance (500 pF to

1000 pF). The inter conductor capacitance for balanced cables is normally 100 pF - 120 pF per meter, and

this gives a combination of

power amplifier the advantage to be

interconnected with cables as long as 9 meters and still achieve the similar affect on the treble level as

power amplifiers with an input capacitance of 1000 pF.

The resistive part of the input impedance, for power amplifiers is of minor importance.

From an audible point of view, it does not matter if the resistive input impedance for a power amplifier is

or 100 k

, but what really matters when using passive controllers is to keep the capacitive load as

low as possible. The latter is achieved using interconnect cables as short as possible (between the pre-

amplifier and the power amplifier), and have the lowest possible input capacitance on the power amplifier.
