The BTC-2 has a dual-chip, four-channel balanced design that keeps the positive and negative signals separate through both decoding and amplification, significantly reducing noise and distortion for clearer, more accurate sound. The ES9018K2M, a low-power DAC designed for stereo systems, gives precise reproduction whether the music arrives by Bluetooth or S\/PDIF, and an OPA1652 audiophile op-amp, with strong current drive, a fast transient response and a low noise floor, and two RT6863 amplifiers do the driving: 280mW + 280mW balanced and 190mW + 190mW single-ended.\u003c\/p\u003e\n\u003ch3\u003eThree inputs, four outputs\u003c\/h3\u003e\n\u003cp\u003ePress SOURCE to switch between Bluetooth, S\/PDIF digital and line in.

Headphones connect by 6.35mm, 4.4mm or 4-pin XLR. The 4-pin XLR is the full-power balanced output; the 4.4mm output is deliberately quieter, with a better signal-to-noise ratio for sensitive headphones and IEMs, and can also help if a system picks up hum. Matching the impedance gives a natural sound with well-defined bass; planar headphones are especially sensitive to it, so try the settings once you know the sound. A higher setting gives more output power, because it drives a harder load, unlike a solid-state gain switch.

A resistor network of 128 high-precision thin-film resistors (four groups of 32) converts the digital signal to analogue. Before it, an FPGA enhances the digital signal and outputs separate L+, L−, R+ and R− bitstreams for fully balanced decoding, while the audio bridge passes DSD through unaltered and converts PCM to a 1-bit DSD512 bitstream, re-clocking, de-jittering and re-shaping the data on the way.
