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 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)
