TOPPING L70 Full Balanced Headphone Amplifier - NFCA Technology, 146dB Dynamic Range, Ultra-Low Noise (Black) TOPPING

Comprehensive Details

Ultra-High Performance NFCA Amplification

The L70 is equipped with the same advanced NFCA modules found in the TOPPING A90, delivering incredibly low distortion, ultra-low noise at 0.3μV, and an impressive dynamic range of 146dB. This ensures that every detail across all headphone types is revealed with extraordinary clarity and precision.

Versatile Output Compatibility

The L70 supports multiple output types: 4-pin XLR, 4.4mm balanced, 6.35mm, and 3.5mm single-ended. Its fully balanced circuitry provides powerful, clean output, making it ideal for both balanced and single-ended headphones.

High Voltage & High Current Drive Capability

With up to 52Vpp balanced output voltage and a peak current of 1.4A, the L70 effortlessly powers even high-impedance and low-sensitivity headphones. Its ultra-low output impedance of less than 0.1Ω ensures accurate response and optimal performance.

Dual Gain & Volume Memory Settings

Switch between low and high gain modes to suit sensitive in-ear monitors (IEMs) or power-hungry over-ears. Save volume/gain preferences for up to 8 different output scenarios, allowing for safe and convenient switching between devices.

R2R Relay-Based Volume Control

The L70 features precision relay-controlled R2R volume, ensuring perfect channel balance, durability, and remote control functionality. No imbalance occurs at low volumes, providing consistent and accurate audio reproduction.

Headphone Amp + Preamp Function

Use the L70 as both a headphone amplifier and a high-fidelity preamp. With 20Ω single-ended (SE) and 40Ω balanced output impedance, it pairs well with a wide range of power amplifiers 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 functionality, ensuring coordinated and clean system integration.
