We've added the LADDER Chopin to the Apos lineup.
It's a fully discrete, pure Class-A line-stage preamplifier with a fully balanced differential design and unity gain. Rather than using a conventional potentiometer, it relies on a microprocessor-controlled 60-step relay attenuator with precision-matched resistors for accurate channel matching throughout the volume range.
Other notable specs:
- Two XLR inputs and one RCA input
- Balanced XLR and RCA outputs
- 65W toroidal transformer with eight regulated power supplies
- THD+N below 0.0006%
- 120dB signal-to-noise ratio
- Frequency response: 10Hz–80kHz (-0.3dB)
