• 【Ultra-High Performance NFCA Amplification】 Equipped with the same advanced NFCA modules as TOPPING A90, the L70 achieves incredibly low distortion, 0.3μV ultra-low noise, and 146dB dynamic range—ideal for revealing detail across all headphone types.
• 【Versatile Output Compatibility】 Supports 4-pin XLR, 4.4mm balanced, 6.35mm and 3.5mm single-ended outputs. Fully balanced circuitry ensures powerful, clean output whether using balanced or single-ended headphones.
• 【High Voltage & High Current Drive Capability】 With up to 52Vpp balanced output and 1.4A peak current, the L70 effortlessly powers high-impedance and low-sensitivity headphones while keeping ultra-low output impedance (<0.1Ω) for accurate response.
• 【Dual Gain & Volume Memory Settings】 Switch between low and high gain modes for sensitive IEMs or power-hungry over-ears. Save volume/gain preferences for up to 8 output scenarios—ensuring safe and convenient switching.
• 【R2R Relay-Based Volume Control】 Precision relay-controlled R2R volume ensures perfect channel balance, durability, and remote control functionality. No more imbalance at low volumes.
• 【Headphone Amp + Preamp Function】 Use L70 as a headphone amplifier or a high-fidelity preamplifier. With 20Ω SE and 40Ω balanced output impedance, it pairs well with a wide range of power amps and active speakers.
• 【Ground Loop Terminator & 12V Trigger】 Eliminate hum with the GND/LIFT switch, and sync power with other devices via the 12V Trigger in/out—perfect for clean, quiet, and coordinated system integration.
