(the two speakers cable must independent connect, no grounding together),
we must strictly in accordance with the marking of plus or minus cable connection,
this class D amp is recommend to the DC volts input 18-24V(not less than 1.5A)
The TDA7492 power chip work in high switching frequency even our human ear cannot hear,
but it will wounds uncomfortable when music reproduction.
Thanks for Indeed Hi Fi Lab, this Indeed TDA7492s Class D amplifier has been design in high bias;
so it has a constant current though to air coil / Wima cap also by pass to grounding.
It reduce the “Digital sound” with more vocal for hear.
It also produces heat from air coil when a bit current to consumption.
We have tested the amplifier in lab over 30days still power ON.
It hot as Class A high grade amplifier to work well!
Notice!!
If you have child in family or worry the risky of high temperature, please think twice to buy it!

Review
Hi Peter!
Thank you very much for the amplifier, it is amazing, i can't believe the
quality sound it is producing and the power, I’m feeding it with a EMU 0404 USB
(good DAC) and have connected it to a pair of Dibeisi DBS-5715 8Ω 750W PA
Speakers (1x Horn tweeter, 2x Piezo tweeters and 2x 15'' Woofers per speaker)
with good cables (BELDEN BE46381 2.5mm + banana plugs) and it sounds perfect! It
can easily achieve loudness beyond comfortable listening levels without
distortion!
It already sounds perfect, the sound is really crisp and warm, with deep and
tight bass, absolutely no noise from the device (can't hear anything from the
speakers with no signal and everything powered on, even with the amp volume
above 25%) and all that up to really high volumes without distortion.
I believe that you have done a wonderful design, it is beautiful to the eyes
(inside and outside) and to the ears.
Best regards,
