Technical Specifications
Signal Path
Fully analog signal path.
Two independent discrete tube phono preamps, one per channel.
Topology: two-stage vacuum tube amplifier with passive RIAA correction and zero global negative feedback.
Tubes: aerospace and military-grade miniature dual triodes 6N16B/6N17B, rated for 10,000+ hours of service without degradation.
Phono preamps signal chain: tubes, resistors, and capacitors only.
Cartridge load: 47 kΩ.
Linear Power Supply
External, unregulated. Custom toroidal transformer wound to specification.
Noise Floor
Line inputs: −120 dB. Tube phono preamps: −75 dB.
EQ
Three-band equalizer per channel. Range: ±24 dB.
Metering
Hybrid metering. Fully isolated from the audio signal path.
LED matrices — stereo, per channel (Ch A, Ch B, Master) — display individual channel levels. The LED scale runs from −21 to +6 dB relative to nominal level, calibrated to IEC 60268-10 (Peak Programme Level Meter standard), the same scale used in professional broadcast and tape machine equipment. Sifam vintage VU-meters (2 × needle) display the bus sum: the mixed signal of both channels, not the master output.
Warm white LED illumination.
Inputs
Each of the two channels provides a line input (RCA) and a phono input (RCA), selectable per channel.
A stereo effects return (RCA) serves as a third input channel — full stereo mix capability, without equalizer or gain trim.
Outputs
Three independent outputs, each with its own level control:
Master — balanced XLR and unbalanced RCA.
Booth — balanced XLR and unbalanced RCA.
Record — unbalanced RCA.
Stereo effects send — RCA.
Headphone output — 6.3 mm jack.
Controls & Connectors
Potentiometers and faders: ALPS — smooth, precise, long-service action
Connectors: Neutrik (Liechtenstein) throughout
