The PA7 is one of Topping's most powerful desktop amplifiers. The new PA7 class D amplifier is capable of 210W x 2 @4Ω THD+N<10%, supports TRS, XLR, RCA inputs. A BYPASS switch allows volume control via a DAC (digital-to-analogue converter) or preamplifier. The design of the aluminium enclosure amplifier matches Topping's E70, E70 Velvet and L70 devices.
