Mackie HM-4 Headphone Amplifier

Q: What is the amplification amount of this device? I am going to connect to tv out with low sound level and need to increase the sound output for 2 peop

Its definitely enough for two people. I use it to play electronic drums along with music tracks and it works well. Tv would probably require less volume and be equally acceptable.

Q: Does the mackie hm-4 come with a 1/4" to 1/4" tsr cable in addition to the included 12v power supply?

Hi, no it comes with HM-4 and the 12 VDC Power Supply, that's all,. Typically manufacturers don't give cables like that since it adds to the cost for them, and many people already have tons of cables. Please let us know if you have any other questions, thank you

Q: Does this work in reverse, i.e., can I plug 4 stereo (line level) inputs and mix them to a single stereo output?

No, it is one input only, it's not designed (nor will it work) in the opposite direction

Q: do the mackie hm-400 bass, treble and balance pots have a detent?

I dint know. I obliterated have the 4-user version, which does not have any sort of adjustment aside from volume... and there's is no detente.
