## Questions & Answers

**Q: Are the individual outputs amplified beyond normal "line-level" voltages? In other words, if the input is at max volume, will the output be louder?**
A: The amplifier circuit has a maximum voltage gain of 10 (20dB).  However, the actual gain you can get will depend on the impedance of the headset you plug into any given channel.  The design calls for a 47 Ohm output resistor for each channel, but the two I received were manufactured with 470 Ohm resistors installed, so the output impedance was ten times what it was supposed to be.  People getting units assembled with this error will see far lower gain than they should.  Beware!

**Q: could this device be bridged like a car amp?**
A: If you mean could you listen to headphones in the car with this, it is possible if you are a good technician or if your car unit has a “pre” or “pre-amp” output.   Trouble is the device has a wal-wart that wants alternating current and concerts it to direct current but you could look around for a CLA with the proper output voltage and tip.  So with a pre-amp output, the proper cabling, (rca l/r to 1/4” stereo or trs) and the appropriate power supply this will power headphones in your vehicle.  CAUTION:  Using headphones while driving is illegal in many jurisdictions- check your state or local traffic codes.  This will not drive speakers well by the way... the output power is too low.  Good Luck!!

**Q: Can i sub the power supply for a 12vdc usb cable? would usb sufficiently power this unit?**
A: USB ports supply 5V, not 12V, so, no, you can't power this thing with a USB cable.

**Q: Can this be used to amplify the sound coming from microphones in an auditorium (I will be using headphones)**
A: I very much doubt it.  This is a "line level" amplifier.  Line level voltage is much higher than the voltage coming from a microphone.  This amp is not designed to amplify a microphone.
