A:AnswerYou can but it needs to be a powered subwoofer. I have (2) floor speakers on A and (2) bookshelf speakers on stands on B with my powered sub on Line 3.
A:AnswerAn old style analog turntable can and will work with this receiver if and only if it has a preamp switch on it. Unfortunately not all turntables come with preamps. A lot of the newer higher end turntables come standard with a preamp switch. You can usually find the switch on the back panel next to your analog inputs. If it's an older turntable it most likely does not have a preamp switch or preamps and would require the purchase of a preamp box to bridge the turntable to the receiver.
A:AnswerHello - You can not directly plug in a microphone to this receiver. However, the Bluetooth feature is great and I do believe there are Bluetooth wireless microphones out there that would solve your question.
A:AnswerAs long as the speakers have the same impedance, the amplifier circuit will power all four speakers. All stereo components process a single input.
A:AnswerThis unit provides radio input although I never use it.
I can input HDMI sources from my smart TV (from WIFI not cable)
& my laptop.
This unit provides separate Bass & Treble controls.
My speakers are bass reflex and do not require 200 Watt power,
so my installer set the output to 80%.
This unit is the 4th one I have used with my speakers since 1975.
I enjoyed the sound so much that I bought a 2nd one as a spare since it has the same sound quality as my first amplifier (Harmon Carden).
