Block Audio Line and Power Block




























Pictures by Hifistatement

Features:
Battery powered Dual-Mono configuration
Both channels, supply units and non-audio circuits are physically separated, shielded and electrically isolated
Battery supply for audio circuits - each channel is powered by its own battery bank
At least 15 hours battery operation and a smart automatic function will activate charging mode when the battery becomes empty, or preamp is switched off
Short audio signals paths without any internal wiring
An overall symmetrical design
Separate grounds for left and right channel
Class-A operation, all discrete audio circuitry
DC signal coupling with Servo-Control
Symmetrical relay volume attenuator
Adjustable input sensitivity and channel balance
Full HT bypass function for all inputs
The output phase invert function
Two custom low-noise and low-radiation toroidal transformers with decoupled cases
2 × 120 000 µF of power supply-filter capacitance
Own physically separated and electrically isolated power supply for non-audio circuits
Selectable Battery or AC Mains operation mode
Built-in headphone Class-A amplifier
Selectable Auto Power Off mode
Auto brightness controlled graphical display and status LED
Infrared remote control
Optional MM/MC Phono stage
Eco/Auto Eco mode control and temperature indicator for power amplifier*
