How to hook up your SEGA Genesis – Model 3
This page will show you the various ways to get your SEGA Genesis 3 up and running!
SEGA Genesis – Model 3
Ports and Connections
SEGA A/V OUT:
This port is used for the SEGA Composite RCA AV Cable (red, white & yellow). And can be used with an RF Box.
AC ADAPTER:
This is the power supply port for the SEGA MK-1479 AC unit.
The SEGA Genesis (Model 3) has two different ways to connect to your television.
RF: the cable that was packed with all the units, but provides the worst picture quality. You should only use this method if you television does not have RCA available.
COMPOSITE RCA: this provides the best picture quality available from the Master System and is what GameTrog recommends.
METHOD #1 – RF Connection
What you will need:
SEGA Genesis
(Model 3 – MK-1461)
SEGA RF Box
(MK-1632)
SEGA MK-1479
AC Power Supply
This is the method that most of you will remember. It was the staple method of hooking game systems up to a TV starting with PONG and still used for the XBOX and Playstation 2. It is by far the worst way to go for picture quality. The reason being is that all the video and audio signals are compressed into one coaxial cable and jammed in to the TV, letting the television split it apart on its end. This causes a fuzzy picture, often accompanied by rolling lines! But if you only have a Coaxial input on your TV, what else can you do?
STEP #1 
Plug the SEGA RF Box cable into your SEGA Genesis. You use the cable with the end that just plugs in, not the end with the screw on it.
STEP #2
Attach the other end of the SEGA RF Box to your television cable port. (see diagram) If you are currently using this port for your Antenna, Cable or Satellite TV, and you only have one port (unlike the diagram), unscrew the cord, screw in the RF box, and then screw the TV Cord to the port supplied on the RF box (shown on bottom of illustration). This way your TV source will continue to work.
STEP #3
Change the CH3-CH4 switch (Which is located on the MK-1632 RF box) to desired channel. The channel shouldn’t matter. This channel would be your TV’s tuner channels or local channel, not a cable or satalite provider’s channel. On your TV’s INPUTS this is normally refered to as AIR.
STEP #4 
Plug the SEGA MK-1479 Power Supply into the back of the SEGA Genesis.
STEP #5
Plug the SEGA MK-1479 Power Supply into the wall.
STEP #6
Plug in a game and turn on the SEGA Genesis, even if you don’t see it on the TV yet. On the SEGA Genesis 3 there is no LED light for power, just orange paint (lame) so there’s no way to tell if the power is working, but when you’re searching for the right channel or input and you see the game, you got it right!
STEP #7
Turn the TV to the channel you picked on the back of the game system. If you have a newer model TV, you probably have several INPUTS SOURCES available from COMPONENT, VIDEO 1 2 & 3 and so on. If this is the case you will most likely need to change it to AIR, which you may also have more than one option (AIR 1 or 2 or A and B, as shown on the above diagram). To change to these different video signal options, you usually have an INPUT or SOURCE button on your remote or television. If everything went right (and your game works…) you should be in business!
STEP #8
See how far you can get in Sonic 2!
METHOD #2 – RCA Connection
What you will need:
SEGA Genesis
(Model 3 – MK-1461)
SEGA Genesis Model (2-3)
RCA AV Cable
SEGA MK-1479
AC Power Supply
This method will give you the best picture quality you can get from the SEGA Genesis. It is the method you should use whenever possible as the improved image quality over the RF connection, is very noticeable.
STEP #1
Plug the SEGA Genesis Model 2-3 RCA AV cable into your SEGA Genesis.
STEP #2
Attach the other end of the RCA cable to your TV. You could have multiple options available like on the diagram. You can place it in any one that is not in use. YELLOW is always the VIDEO and should be plugged into the YELLOW port. RED and WHITE (right and left respectively) are the sound and should be plugged into the proper color for the cable.
STEP #3
Plug the SEGA MK-1479 Power Supply into the SEGA Genesis.
STEP #4
Plug the SEGA MK-1479 Power Supply into the wall.
STEP #5
Plug in a game and turn on the SEGA Genesis, even if you don’t see it on the TV yet. On the SEGA Genesis 3 there is no LED light for power, just orange paint (lame) so there’s no way to tell if the power is working, but when you’re searching for the right channel or input and you see the game, you got it right!
STEP #7
Turn your TV to the appropriate VIDEO SOURCE You probably have several INPUTS available from COMPONENT, VIDEO 1 2 & 3 and so on. In the diagram above you would need to change your TV to VIDEO 1. To change to these different video signal options, you usually have a INPUT button on your remote or television.
