SPEAKER OUTPUTS: Output jacks for connecting external bass speaker cabinets (these jacks
are wired in parallel). The overall impedance rating is 4 ohms. For instance, you can connect
one 500 watt cabinet with a minimum rating of 4 ohms or two 500 watt cabinets with a
minimum rating of 8 ohms each. If you operate the BASSBASE 400 at a higher impedance
rating, power output will decrease accordingly.
It is very important that you heed the maximum rated handling capacity of any speaker
cabinets you choose to connect, especially if you have borrowed them from someone you
want to remain friends with.
