Radio Shack MPA-125 - Manual (Page 7)

7 Connections
Connecting an Auxiliary Sound Source
You can connect any high-level sound source, such as a CD player, tape deck, or tuner, to the
CD/AUX jack on the back of the amplifier.
Connecting the MIX BUS Jack
You can connect another MPA-125 to this jack to double the size of your PA system. This lets
you use up to eight microphones (or six microphones and two turntables), and two auxiliary
sound sources.
Use a shielded cable with phono plugs at each end, and connect the cable between the MIX
BUS jacks on the back of the two amplifiers. For the best results, do not use a cable longer than
6 feet.
Connecting an Equalizer
You can connect an equalizer or other external signal processor to the EQ IN and EQ OUT jacks
on the back of the amplifier.
Note: You can also connect a tape deck to the EQ OUT jack for recording.
