ZG-1449-18

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
