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)
The receiver chip is WM8805 and the oscillator used is TCXO.
Chips used are STA510A for stereo channel, and sta508 for bass channel.
2x100W@6ohm (or 2x75W@8ohm or 2x65W@4ohm) + 160W@4ohm
There is a +10dB function (DIP switch 4)
Voltage range: single 15 to 36VDC or dual rail 12 to 26VAC.
Max 30VDC (20VAC) if you use 4ohm speakers for stereo. Overload might occour if using 4ohm speakers on stereo channel @36VDC.
Sample rates accepted: 32 to 192 kHz
Resolution: up to 24 bit
Bass channel can be disabled with a DIP switch.
Additional 4 inputs available on board (2 x SPDIF and 2 x CMOS)
