PA7 Plus is Topping's most powerful desktop power amplifier yet. The new PA7 Plus Class D amplifier is capable of an impressive 300W x 2 @4Ω THD+N<10%, supporting TRS, XLR, RCA inputs. A BYPASS switch allows you to control the volume 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.
