MCX300 AM-FM Tuner and Cassett e Tape Player
'HVFULSWLRQ
The Rauland MCX300 AM-FM Tuner and Cassette Tape Player comes ready to be rack-mounted. It includes a separate 12-VDC power supply that can be plugged into any convenient 120-VAC power outlet. There is a standard female “F” connector to accommodate a coaxial cable from the external antenna required for the AM-FM tuner, and an RCA-type phono jack for connecting the unit’s unbalanced monaural audio output to a sound or communications system. The audio output provides ample signal for the auxiliary input of an amplifier or a communications system.

General Information
Revised Model
This manual is for the revised MCX300, which began shipping in May 1996. It features a slightly different tuner and tape player but retains the same specifications and convenient plug-in connectors as the previous model. For the older-versions of the MCX300, see KI-1745, KI-1967, KI-1950 and KI-1972.

An external 75-ohm antenna is required for the AM-FM tuner. The type of antenna to use depends upon the equipment’s location within the building and the strength

Page 6

of the radio signals in the area. For most installations, Rauland recommends the antenna system shown in the attached wiring diagram, KM0710.
The system should be installed with some protection against lightning. Articles 810 and 820 of the National Electrical code, ANSI/NFPA No. 70-1978, provide detailed information regarding the grounding of
structure, cable system. The Code also specifies the size of the grounding conductors, the locations of the antenna discharge units, the connections to the grounding electrode, and the requirements for the grounding electrode. An example of an installation meeting these requirements is given in the attached illustration, IL0153.
Audio Output
Obtain a single-conductor shielded cable of suitable length to connect the Audio Output jack on the back of the chassis to the Auxiliary or Tuner input of the sound or communications system. T erminat e one end of the cable in a male RCA- type phono plug; the other end should have a connector that matches the input of the system.

Plug the RCA-type phono plug into the “Audio Output” jack of the MCX300, and the other end of the cable into the “Auxiliary” or “Tuner” input of the main system.
Power
Insert the output plug of the power supply into the “Power Input” jack on the back of the MCX300, then plug the power supply itself into a suitable 120-VAC outlet.

The attached IL0153 suggests a grounding system for an AM/FM antenna system; the attached KM0710 illustrates a way of mounting the AM and FM antennas.
The following Rauland-Borg parts are used in the suggested system: FMT-65 FM Antenna. LV0027 AM/FM Antenna Coupler, which includes:
The coupler itself.
9
An outdoor housing.
9
Two screws for mounting the coupler inside the housing.
9
A “U” bolt and related hardware for mounting the housing to the mast.
9
QC0126 Lightning Arrestor. This includes the hardware needed to mount the coupler to the mast.
The remaining parts shown in KM0710 (wires, coaxial cable, the antenna-mounted matching transformer, “F” connectors, the masts, and the AM insulators) are readily available from suppliers.
Mount the parts firmly to the mast, as shown in the illustrations, to properly ground the antenna system.
Operating Instructions
Refer to the separately supplied vendor's instructions for the tuner and cassette player’s operation and care.

The “Program/Monitor” position plays the unit through both the system and
9
the monitor speaker. The “Off” position disconnects the unit’s output from both the system and
