Class A Instrument Input
The Instrument Input is a fully dis crete impedance converter
that also operates in class A mode . It is based on a low-noise
field effect transis tor that, due to its ext remely high input impe-
dance, is es pecial ly well s uited to this ta sk.
Relay switching
In order to ensure the shortest possible signal paths, nearly all
switching functions are handle d by optimally positi oned, encap-
sulated relays with gold-plated contacts (the switches them-
selves only trigger the relays). Sin ce resistors also gr eatly affec t
audio quality, the entire audio signal path utilizes painstakingly
selected resistors with 0.1 % tolerance.
Foil condensers
The op-amp circuits use premium FKP f oil condensers, which
sound much more open than ceramic type s and provide more
natural dynamic response.
