Product description

• Compatible with a wide range of op-amp chips If you want to personalise your audio experience with the A70's op-amp rolling feature, you can try using a compatible eight-pin dual op-amp chip, such as RT3609SM, OPA2604, OPA2134, LM4562, JRC5532, OP275GSZ, OPA1612, and more. Note It is to replace the op-amp chip of the second board underneath.
• Richer Input Methods This 2-channel amplifier has RCA inputs, balanced inputs and trigger inputs, and adds RCA gain switches to adjust the sound according to your needs. Its 12V trigger input connector can be synchronised with other devices, simplifying the switching process and eliminating the need for separate operation. Note The 12V trigger must be connected to a preamplifier and must come with a 12V trigger output not compatible with WiiM brand.
• Advanced Thermal Technology Based on the groundbreaking thermal design of the A70MAX, we have upgraded the A70's cooling system by adding dust caps to the vents on both sides for better ventilation, resulting in constant and stable high power output.
• Versatile design Vertical desktop configuration allows for flexible placement in any setup while taking up minimal space. And the large crystal terminals make it more stable and sound layered for big dynamic music.
• What you get you get an A70 amplifier, a 48V5A gallium nitride power supply, and a manual. Note You need a more powerful power supply to get the MAX 4 Ohm 300W x2 power output, such as 48V 10A
