Overview

Fully balanced operation with a simple circuit topology that allows low negative feedback, and a high current/low impedance output stage.

High voltage, precision-regulated, power supplies to provide stable operating conditions for each gain stage and are carefully isolated from the audio circuitry.

Signal control is handled by a precision relay-switched volume system.

Fully balanced differential linestage with increased functionality
Precision-regulated B+ and B- supplies
Tube life extender circuit with B+ delay and soft filament ramp on power on
Balanced design, low-radiation power transformer
Quiet logic: Microprocessor sleep mode, quiet non-matrixing LED display with latching shift registers
All-tube, with lower gain high current 12AU7 circuit and 12AT7 buffer, minimal negative feedback
Two balanced /single-ended inputs, five single-ended inputs, one tape in, one balanced out, one single-ended out, one buffered record out
Soft-touch relay input select
117-step chip-based differential volume control, with 3-digit display
Higher resolution via single higher-resolution attenuator, and software control for balance and offset
Switchable gain between normal and low gain
Mono control on front panel
Fully bi-directional RS-232 control: programmable input offset, any input programmable as pass-through, and input disable, tape monitor and Mono control on front panel
Two programmable trigger outputs
Full function aluminium metal remote
TP-6.5 chassis size with all precision machined aluminium cosmetic
