The Alchemy DPA-2 power amplifier is about dynamic musicality, thanks to design that combines Class A circuit topology composed of discrete FETs and a linear power supply using a toroidal transformer. The pure analog input stage preserves all the detail and nuance of the most delicate passages. The Class D output stage with switching power supply results in impressive output combined with cool-running efficiency.
The power output of the DPA-2 isn't just formidable, it's easily configurable for the needs of every system. Producing 325 watts-per-channel in stereo, the Alchemy amplifier can be easily switched to deliver 650 watts in monaural mode, sufficient to drive demanding, power-hungry loudspeakers.

• Selectable high/low gain to match any preamplifier

Q: 1. HI! Since Windows 7 and 10 do not have multichannel output (only 2 channels can be heard), I decided to work 2 8 channel sound cards simultaneously. I am a composer and want to compartmentalize the orchestra into 16 distinct channels using software that would let me do that. Sound source will be taken from their analog outputs. This is why I am looking for 2 8 channel amplifiers. Can this be done with the Pyle? Thank you, John

A: If your audio interface or sound card has 16 outputs outputs, you can then connect them to the 8 unbalanced RCA stereo pairs on two of these amplifiers, and then send the signals out to passive speakers.

Q: 2. What is THD rating(s) for this amp?

A: Unfortunately this manufacturer has chosen not to publish this and other specifications.

Q: 3. Can we use 220 volts

A: Yes. This unit's voltage selector range from 110 v to 220 volts.

Q: 4. Can be using 220 volts

A: Yes . Power 110/220V Switchable (DC 12-15V)

Q: 5. where are the volume controls it looks bare of any knobs it said independant 8 channel?

A: The volume controls are located on the back. I use this unit as an amplifier for speakers throughout my house, each channel goes to a wall volume control knob first, then to speaker. I would highly recommend adjusting the channel control knobs on back of amp to limit the output to wall unit or the amp will burn them up. Go ahead and get 100 watt wall units if this is what you want to use it for. The amp is adjusted to about 60% output for each channel. I do have speakers also hooked up directly to amp as well (NO WALL CONTROL) , I just have the volume statically set for that zone, as for it would be very inconvenient to change the volume on the amp.

Q: 6. Does it have fans to keep it cool?

A: Yes the Yamaha PX8 amplifier has cooling fans.

Q: 7. Will this work with a Audio Technic U855QL podium microphone, (Dynamic)?

A: The Pyle Pro PCAU25A 80W Stereo Power Amplifier BH #PYPCAU25A does not have a microphone input.

Q: 8. Can this be used with an equaliser?

A: Yes it can. It normal practice to use a graphic EQ for your monitors.

Q: 9. Got a pair of yamaha cbr15 inch speakers. Will px5 be suitable for the speakers

A: Yes, the Yamaha PX5 Stereo Power Amplifier is compatible for use with a pair of Yamaha CBR15 Speakers.

Q: 10. Can we use PX3 pro amp for hometheater setup and home or this is for commercial purpose like events and functions .. thanks

A: This is generally used for either amplifying PA speakers or for commercial use. Usually home entertainment speakers require an amplifier that pushes a different impedance. This amp does 300w at 8ohms per channel and 500w at 4ohms per channel. Most home entertainment speakers run at 6ohms and are generally a lower wattage.
