2 channel mic/instrument/line tube/hybrid preamp in 19" 1U rack format

Design concept: (tube) pentode hybrid preamp, transformer input and output
2 channels
Switchable input impedance (for mic input only): 900Ohm, 10kOhm, 2.4kOhm
Instrument (DI) input impedance: 3.9MOhm
Balanced line input impedance: 15kOhm (dedicated input transformer)
Output mode: Transformer or solid state balanced driver
Low/high frequency shelving boost, corner frequency varies (see manual)
Frequency response: 10Hz-50kHz +/- 3dB
Maximum gain: 76dB (mic); 50dB (line and instrument)
Gain control range: 36.7dB (for mic input, Pad switch adds another 10dB)
Harmonic distortion: <1% before clipping level, quickly decreases if driven less.
Maximum output level: 32dBu
Minimum output load: 600Ohm
Connectors: XLR mic and output, balanced only
Instrument input: 1/4” unbalanced, mono
Power consumption: 50W
All supply voltages regulated (including heater)
285V Plate voltage for huge headroom
Gold plated printed circuit boards with a double copper layer.
Gold plated tube sockets

The Berliner can be ordered with Ni-Fe alloy or pure Steel output transformers:
Berliner A: 2 Ni-Fe alloy core output transformers
Berliner B: 2 pure Steel core output transformers (the choice of most people)
Berliner AB: Ch1 with Ni-Fe transformer, Ch2 with pure Steel.
Please specify mains voltage when ordering: 115VAC or 220-240VAC.
