Chipset: TPA3255 + NE5532
・【Equipped with PFFB】 The [Aiyima] A70 is the first stereo home audio Class D amplifier on the market based on TI’s TPA3255 chip with a post-filter feedback loop (PFFB).
・【Equipped with 12V Trigger Input and RCA Audio Input】 The trigger input allows for easy one-button activation of the audio chain from the source. This gain switch can be used to boost the signal input into the RCA input.
・【Balanced Input】 The [Aiyima] A70 stereo amplifier adopts XLR audio signal input.
・【With RCA Output and Sub-Channel Output】 The sub-channel output with variable filter output is controlled by the volume setting and adds an adjustable cutoff frequency (20-150hz/20-600hz) to the low-pass filter output, allowing you to easily build a 2.1 channel audio system to match your desktop speakers.
・【Professional Audio Components】 Simple appearance with professional audio components, excellent performance, measured SINAD up to 96dB, and S/N ratio up to 116dB, providing excellent audio quality.
・【Replaceable Op-Amp Chips】 Explore subtle changes in sound quality and increase the fun of customization by replacing op-amp chips such as Sparkos SS3602, MUSES02, OPA2604, OPA2134PA, OP249, AD827, RM4558, LM4562, and LME49720HA.
・[A70 Note] When turning off the power, a slight popping sound may be heard, but this is normal. Please do not be concerned.
【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device's requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
