Hifimediy DDX320v2 2.1 Digital Amplifier

This is a 2.1 (stereo + mono bass channel) amplifier that takes a digital signal, coax or optical. The crossover frequency between stereo channels and bass can be set from 80 to 360hz or bypassed. The amplifier can also be used as a stereo amplifier without crossover and without using the bass channel. The crossover is a preset filter in sta320, and it's 2nd order low pass and 1st order high pass.

It comes with a remote which adds some extra features (EQ, set crossover frequency, adjust display brightness, swap L-R channels, mute, change channel, standby, volume)

We have solved the noise bugs present in the first version of this amp!

We are not able to ship the batteries for the remote, because of shipping restrictions. The battery needed are 2 x LR1130/L1131/389/AG10/CR2880  (1.5V)
