Product Description

  • Immaculate Condition.
  • Original box, packing & cables.
  • Factory Manual & Warranty Card
  • Finish: Black

Topping A90 Headphone Amplifier

The Topping A90 is nested feedback design; this means that the A90 uses cascaded op-amps in conjunction with negative feedback loops that help control each op-amp. The way this works is an op-amp is placed at the output of the previous op-amp in the series and a negative feedback loop adjusts the output of each op-amp into the next. The outcome is an amp with a higher gain, faster slew rate, and lower distortion than an amp using the same op-amps in parallel.

Features

  • Two pairs of XLR jacks and 2 pairs of RCAs; one each for input and outputs.
  • Can be used with two different sources via the selector switch on the front panel.
  • Can output up to 18V on the low gain and up to 49V on the mid and high gain settings
  • The front face has a series of 3 switches on the left side, headphone ports (XLR, 4.4mm balanced and 6.35mm single-ended) placed in the centre and the volume knob is situated on the far right.
