Alice 501T - 500-Series Mic Pre with Transformers

Alice 501T - 500-Series Mic Pre with Transformers

The Alice 501T is a high-performance transformer balanced microphone preamplifier. The 501 T is designed around Alice's legendary XTX131v2 matchamp which achieves a noise performance which is typically less than 0.5dB from theoretical Johnsons noise.

Next the mic amplifier itself. This is a discrete specially designed amplifier produced by Alice. It’s brilliantly stable and has excellent gain range, it’s almost impossible to overload so it does not need an overload indicator. The gain control gives plenty of range to use all mic types from ribbon mics up to studio condenser types.

To retain best possible quality of the audio, the output goes through another transformer, this gives you isolated balanced output and perfect matching to any line level input. The front panel has switching for phantom power, a rotary gain control and a phase switch which changes the polarity of the audio from positive to negative.
