Preamplifier has two functions which seems very simple, and they are: volume control and input selection. For that simple reasons we have taken great care in design of our passive preamplifier.
High-quality TVCs (copper windings) from Audio-Consulting and effective solution
for attenuation with relays resulted in direct and natural sound of our preamplifier
Ecstasy IVse.
In our preamplifier we are using relays with Ag + Au clad bifurcated crossbar contacts which are fully sealed for high contact reliability, and there is no loss in signal quality because of that. Mechanical rotary switch is only used for control of above mentioned relays.
