Class AB AT1820 Series – Amplifier Technologies Inc.

Beginning with the the two-channel AT1822 to the seven-channel AT1827, all AT1820 Series amplifiers feature ATI’s Soft Turn-on protection. The Soft Turn-on circuit gradually powers up the amp to avoid tripping the circuit breaker or dimming the lights. At the back of the amplifier, an RCA unbalanced input, an XLR Balanced input, input selection switch and a pair of gold-plated, 5-way binding post outputs support each channel. There is also a 1/8” mono mini jack for +12V trigger, a gold-plated chassis ground lug, a fuse holder and an IEC 20 Amp inlet for the provided detachable power cord. The supplied power cord will have either: a NEMA 5-15 plug (Type B) for use in the USA, a BS 1363 (Type G) plug for use in the UK, or a Schuko (Type F) plug for use in the EU and the rest of the world.
