• Substantial output options: 6.35mm single-ended and 4.4mm balanced outputs with a 3-level gain switch to suit a wide range of headphones.
• Flexible connectivity: USB, Optical, Coax, and RCA inputs; XLR, RCA, 4.4mm, and 6.35mm outputs enable diverse configurations, from compact desks to full setups.
• Sound customization at your fingertips: bass/treble EQ, six filter types (including Bypass), and two swappable op-amps for a tailored listening style.

Real-world use cases you might enjoy

• Desktop HiFi with headphones, offering a clean, low-noise foundation for detailed vocals and instrument textures.

Note to set realistic expectations: RCA and XLR output levels differ, so choose the connection that matches your backend equipment. EQ affects headphone output only to avoid misusing the preamp outputs. The ZH3 emphasizes a balanced, low-noise design that supports a wide range of listening preferences without promising specific loudness or outcomes.
