- Transformer-balanced audio inputs for reliable signal integrity
- Loop-through XLR connectors for chaining multiple units
- Flexible input routing: switchable to left, right, or both headphone ears
- Two headphone outputs per amplifier (A/B gauge 6.35mm jacks)
- Balanced mix outputs of each 4-channel mixer for external routing
- Designed for headphone impedances from 200 Ω to 2 kΩ (supports 80 Ω with reduced battery life)
- Power via 2 x D-cell batteries or external 12–18V DC supply
- LED indicators for battery and external power sources
- Low battery warning indicator
- Compact and rugged for field or studio use
