Question 1

Can this amplifier be used with a turntable?

Accepted Answer

I have hooked this amp to a turntable, so yes.

Question 2

Is it possible to drive several 8 ohm speakers in parallel so that the load is small?

Accepted Answer

when you have 2 sets of 8 ohm speakers connected to an amplifier, you have a 4 ohm load. 3 sets would be about 2.7 to 3 ohms, 4 sets of speakers would be 2 ohms, and so on.. rough values, since impedance is a variable thing depending on whats being played through the amp (speaker impedance is a nominal value, not really exact).

the problem is, the lower total impedance allows the amplifier to generate more current internally than the amp is designed to deliver - and you would need it turned up a ways to drive that many speakers. reproducing low frequencies is problematic too, since with less impedance there is less "damping" or ability for the speaker to return to it's original state after it moves (mostly a problem with bigger speakers).

but ultimately, the power supply or an output chip would likely fail at some point of extended use. 4 ohms is the practical limit, which is 2 pairs of 8 ohm speakers.

Question 3

I have a set of bluetooth ear buds. Can I take sound from my tv through this transmitted to my buds via bluetooth

Accepted Answer

No, see my other answer, but an update, I now see the other device is now on sale so it is no longer more expensive than 
this device.  I still had problems with connecting to bluetooth at times with the IMi device, but maybe I didn't understand the instruction. 
This device  will do what you want, but doesn't have all the functions of this amplifier : 
1Mii B06TX Bluetooth 5.0 Transmitter for TV to Wireless Headphone/Speaker, Bluetooth Adapter for TV w/Volume Control, AUX/RCA/Optical/Coaxial Audio I

Question 4

I am hearing impaired but my wife is not.  Can I use this amp to separately drive and control speakers and headphones?

Accepted Answer

The best solution for your suggestion is to use a separate headphone amp (mentioned in another answer), however, you can daisy chain the two components together so that your input source goes through the amp shown in the photo, then take a pair of patch cables and connect one end to the record output of the first amp and the other end of the patch cable to the input of the headphone amp.  Your volume control will be totally independent and can have your headphones as loud as needed while the  volume on the main amp used for the speakers is at your wife's listening preference.  Remember, the connectors marked "output" will handle other amplifiers because that is a "pre-amp" output source.  If the output says "speaker" then you should not connect another power amp to that connection because the second amp will be overdriven by the first amp, possibly causing damage to both.
