Description of Douk Audio Amplifier Subwoofer Full Frequency

Warm tip: G10 is mono channel amplifier, want stereo output please buy 2PCS or 3PCS. Large output power with gain switch: using TPA3221D2 amp chip and comes with 24V power adapter, allows 2-level of output level (21db/27db) for switchable max 100W/200W output power to match better with different speakers. Mono channel with low frequency output: with SUB/FLAT switch, G10 can both as a full frequency amp and a subwoofer amp, and add a SUB output to directly connect active subwoofer. 2PCS G10 can drive left and right channel independently to avoid mutual interference, easy to build 2.0/2.1channel system. Pluggable Vacuum tube design and HiFi sound: using 6K4 tube, sounds warm and delicate, full and mellow, much softer and more listenable. Can be directly replaced by 6J1/6J4/ GE5654/6AK5/6*1N to enjoy different sound styles. Perfect design and powerful function: using reasonable and advanced circuit with high-quality components. With SUB frequency adjustment (40-200Hz), built-in speaker protection circuit, low-pass filter, no audible noise even at high power output. Unique appearance and proper size: vertical placement design more beautiful and fashionable, black solid aluminum chassis looks cool and elegant, both enjoyment of auditory and visual, very suitable for the audiophiles who pursue HiFi sound.

The audio output is distorted much more than the specified 0.1% according to the waveform on my oscilloscope

Pros
  • Easy installation
Cons
  • There are other interesting options.
