GENERAL DESCRIPTION The ACU is a low power, 7-channel, FM stereo transmitter, operating in the FM band (88.1107.7 MHz). The unit has 7 transmitter “cards” integrated into a single 19-inch chassis for rack mounting. It has two 88.1-107.7 MHz output ports for two separate antenna systems. The transmitters can individually operate in either stereo or mono mode. Each transmitter card can be set to a specific operating frequency using the two 10-position rotary switches on each card.

FRONT PANEL FEATURES (refer to drawing 580320-PINOUTS) Stereo/Mono Switch Set to appropriate setting Modulation LED’s LED’s should usually be in the green, with occasional flashes of RED. No LED’s lighted indicates no audio input. SW2(LSB)/SW1 (MSB) Set to appropriate channel. Reference the Frequency Allocation Chart. Power LED LED is lighted when power is applied. No light indicates either there is no power to the ACU, or the re-settable fuse has been tripped.
ANTENNA INSTALLATION The antenna system and ACU, which are exclusively installed in mass transit rail cars, must be professionally installed in accordance with these instructions. The ACU is to be installed in the utility cabinet of the “B” rail car of a “married pair” rail car pair. See the Antenna Connection drawing 550320-ANT. The ACU connects to the antenna system as shown in 550230-ANT.
