Perfect working order. Not modded or messed around with.

Includes board, display, rotary encoder, and instructions. This is the newer version that can learn IR commands. This works well. Lovely clean amplifier. I am only selling as I am going down the dsp route.

Out of stock on hifimediy website, but RRP is $114.00

Price $70 plus shipping at cost. Will ship worldwide. Payment by PayPal only.

















 
I already have a minidsp 2x4. Thanks.

Since this has been bumped, here is some more info.

This is a digital amp with no DAC. The source needs to be digital. This is then directly amplified without the need for conversion to an analogue signal.

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 (requires remote which is not included). 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. The crossover is default set at 80hz, also when the amp is in 2.0 mode.

New version (september 2014) comes without remote but with remote learning feature. You can use any 38kHz (RC5 code) remote that you have to control this amp. Details on how to set the remote in the manual.
The remote is required to: set crossover frequency, EQ, dim display. Without remote you can: adjust volume, switch input channel, set to standby.

SPECIFICATIONS:
•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. Note - crossover is still at 80hz if you don't disable it with a remote.
•Additional 4 inputs available on board (2 x SPDIF and 2 x CMOS)
•PCB Size: 115*115mm*40mm
