The JMK ZG-1449-18 audio amplifier is a dual channel
audio amplifier capable of functioning in an automotive
environment.
Each channel of the amplifier is capable of both simultaneous
and independent operation.
The amplifier uses vehicle 12 volt power and contains all the
necessary filtering and shielding to eliminate electromagnetic
interference from other “on-board” equipment such as trans-
mitters relays etc.
The amplifier is protected against reverse power hook-up and
inadvertent “crow baring “ of the audio output channels.
The amplifier can handle vibration and shock as is
normally encountered in the automotive environment and
storage temperatures of 85ºC. It will operate with a 25% duty
cycle continuously at 60ºC. Typical voice or music signals
can be amplified continuously even at 80ºC
