How to connect a turntable to a amplifier/ receiver

Most of vintage and modern turntable have to be connected to a special input on your amplifier/ receiver labelled PHONO. This input uses a special preamplifier section that a turntable needs before the signal can be sent to the amplifier stage. If your amplifier/ receiver has no PHONO input then you need to buy a separate phono amplifier first.

Important note: 
Some cheap modern turntables already have this phono amplifier fitted in the turntable. In this case you can use any input on your amplifier/ receiver to connect the turntable. Check the turntable's manual first.  

The diagram above shows you how to connect a turntable to your amplifier/ receiver. In most cases the PHONO input on the amplifier can accept turntables fitted with a moving magnet (MM) type cartridge. The PHONO input is a special type of input and is different from all the other inputs of an amplifier. Most vintage turntable and most modern turntable 
must be connected here. 

Playing back music from your turntable
Before switching the power on, set the various controls as follows:
  •      Plug the power cord of these two units into the AC wall socket
  •      Select the speaker switch that corresponds to the speaker system          which is connected to the SPEAKERS  terminals on the rear panel.
  •      Set the bass and trebele controls to "0" position
  •      Set the balance control to the center position.
  •      Select PHONO on the front panel. (Make sure the TAPE monitor is          set to off)
  •      Make sure the volume is set to minimum and switch the units on.
  •      Start playing a record (vinyl) on your turntable and increase the            volume to the desired level.
