Ribbon/Amp Interface





The amplifier interface box connects between a speaker amp and the SR1a, to achieve 5.6 ohms of combined resistance and 140W of power dissipation with moderate temperature increase.

The amplifier connects to binding posts / banana plugs at the back, and at the front, the SR1a cable plugs in to a male 4-pin XLR connector. The connector gender is chosen to prevent the possibility of plugging SR1a into a conventional headphones amplifier and effectively short it, causing damage to both the amp and the headphones.

The Amplifier Interface unit is air-cooled, so it should be kept on top and not covered.
