Commentary
This is a pre-main amplifier that condenses the basic design of the Integra A-817RXII into a compact size of 330 mm wide.
An in-phase transformer is added to the signal system and power supply circuit. This in-phase transformer cuts off the loop with the connected equipment to prevent external interference to the amplifier.
The output is equivalent to that of the A-815RXII.
It is equipped with a direct tone with a Contrabass with a booth in the ultra low range.
