The A90 Discrete features fully discrete components for superior sound, dual gain settings for versatile compatibility, and advanced noise elimination technologies.

Product Details

【Fully Discrete NFCA Technology for Superior Sound】The A90 Discrete uses fully discrete components to enhance the NFCA module, with 4 NFCA-Discrete modules and 39 transistors per module, delivering high output voltage, high current, and low impedance for driving a wide range of headphones effortlessly.
【2 Gain Settings for Versatile Headphone Compatibility】With two gain settings, the A90 Discrete is designed to power both sensitive IEMs and full-sized headphones. The low gain setting minimizes noise for high-sensitivity IEMs, while high gain provides ample power for over-ear headphones.
【Ground Loop Noise Terminator】Eliminate ground loop noise with the GND/LIFT switch on the A90 Discrete. In normal use, set to GND, and when noise occurs, switch to LIFT to enjoy uninterrupted audio. Perfect for complex setups with multiple devices.
【Dual Function: Headphone Amp and Preamp】The A90 Discrete functions as both a headphone amp and a preamp, offering consistent high performance in both modes. Its 20ohm SE and 40ohm balanced output impedance ensure compatibility with various power amplifiers for flexible use.
【Expanded Input Options with Ext90】The A90 Discrete offers 1 XLR and 1 RCA stereo input, but when paired with the Ext90, it expands to 4 XLR and 2 RCA inputs, making it a versatile option for complex audio setups. The 12V Trigger interface allows easy synchronization with other devices.
【Precision R2R Volume Control】The A90 Discrete features R2R volume control using relays and resistor networks for precise, long-lasting volume adjustments. This ensures accurate channel balance and remote control convenience for an optimized listening experience.
【Volume Memory Function for Convenience】The A90 Discrete memorizes output volume settings for PRE, HPA, and PRE+HPA modes, automatically restoring the last used volume when switching back to a previous mode. This feature offers seamless operation across different audio setups.
