Power circuit and vertical symmetry circuit
configuration
The double-transformer configuration which consists of a
1kVA toroidal transformer and an additional sub-transformer
is coupled with the high capacity capacitor to ensure that no
fluctuation occurs in the power voltage even when high
power outputs are required. As a result, this unit becomes a
revolutionary power amplifier which does not possess a
voltage regulator.
The amplifier stage allows more idling current than usual to
flow, and normally functions at Class A, except for strong
power where it functions at Class AB. The vertical symmetry
push-pull output operates in all stages, and helps to avoid
clipping.
Equips WBT’s speaker terminals
The speaker terminals are WBT-0710 Cu which use the pure
material WBT nextgen series. Two sets of terminals enable
biwiring connections.
3 system input
This unit equipped 3 input system terminals, 1 XLR and 2
RCA, which can be selected with the button on the front
panel.
Highly precise, highly rigid chassis
Combined with pin-point feet which distribute the vibrations
equally, and a main chassis and outer design manufactured
by high precision processing at the machining center, this unit
also features an output transistor enclosed and stabilized by
an aluminum block together with a heat sink attached with
stainless steel if 4 mm-diameter fins to eliminate vibrations.
