9 System 2000 Overview: The System 2000 is a time proven standard of Audio/Video entertainment designed exclusively for tour buses. The complete system incorporates: A state of the art digital Audio Control Unit that incorporates advanced digital design for enhanced reliability and complete centralized system control. The Control Unit 2000 allows the operator to control up to three audio selections, allowing custom tailoring of each channel's sound quality. There are three microphone inputs for the Public Address system, which is switchable between internal and external speakers. The unit contains a separate Video Section for controlling the VCP. It also allows the driver to control his own separate audio selections. The Control Head is housed in a shallow DIN-E chassis that allows ease and flexibility of installation. A specifically designed 102 watt RMS per channel amplifier, capable of driving up to twentysix, four ohm speakers. Up to six, custom designed ten-inch color monitors, which incorporate a unique anti-theft locking slide mount. This design makes installation and removal very easy. In conjunction with the Video system, there is a specially modified VHS video cassette player that allows the operator convenient control over its functions. Individual seat audio option. Allows each passenger to choose between up to four channels of stereo audio and one video audio channel. Allows individual volume control of each channel. (See Seat Audio Literature). Camera options: Both a rear-view Back-up Camera and Scenic View Camera option are available for the System (See Back-up Camera and Scenic View Camera Literature). 3

14 PA System In-Dash PA Module Operations: The in-dash Public Address Module automatically goes into standby mode whenever power is applied, indicated with a green power LED. When a microphone is keyed the PA module turns on (PA LED) and volume and tone can be adjusted on the front of the unit. Features: Separate Input Sensitivity Controls are used to adjust the gain of the each of the microphone inputs, allowing for varying microphone performance. These controls should be set to the minimum level that allows for an acceptable volume level. Integrated over-current protection in case of a fault condition. In the event of a fault condition the amplifier will automatically shut off. Once the fault is located and removed, the amplifier will automatically turn back on. +24 VDC Radio Upgrade option available. Dual Priority Microphone inputs: two primary, one secondary. P-2

41 System 2000 Amp 3000 Operations: The amplifier is automatically turned on and off by the C-2000 control head when the power button (on the C-2000) is pressed. There is a red L.E.D., on the front of the amplifier to indicate power is on. Features: A separate Input Sensitivity Control used to adjust the gain of the amplifier. This should be set to the minimum level that allows for an acceptable volume level. Integrated over-current protection in case of a fault condition. In the event of a fault condition the amplifier will automatically shut off. Once the fault is located and removed, the amplifier will automatically turn back on. This circuitry works independently of the main power circuit breaker. Incorporates a separate 24 to 12 volt converter internally. This converter is used to power the C-2000 and the main and auxiliary radios. This supply has a separate 2 amp circuit breaker, located next to the main breaker. A-19

If unit still does not operate verify the slide bracket connections and repair or replace unit as necessary. Form: TS G Series Rev A TS-8

110 Monitors power - up (screens light, green LED on rear panel is on) but no video is displayed; all monitors. VCP not operated properly Verify that a known good VHS tape has been inserted and that the VCP is in play. PLAY LED, on the front of VCP, is illuminated. VCP may be put into play from either the Control Head or directly from the front panel of the VCP. VCP Video out connection defective or incorrect. Check Video Out connection, at the rear of the VCP. Connection should be made to the jack labeled VIDEO OUT or the cable coming out of the VCP with the BNC connector. If possible, remove VCP and check out the unit by connecting it directly into a monitor with a Video input. If unit does not function, repair or replace it. If unit operates, check the cable, in the coach, that connects to the Video Out. Repair or replace as necessary. Defective or improperly installed Video Distribution Amplifier (700769) * May not be installed on all systems. Verify that the Distribution Amp has power connected to it. Verify that it is connected to the Video Out cable, from the rear of the VCP. Verify that the individual coax cables are correctly plugged into it.

Defective Monitor (700182). Remove a monitor from a position that does display video and re-insert it into the position with the suspect unit. If position now display Video proceed to Defective Monitor Possible Cause. If not, Check coax connections, at the rear of the monitor, and at the other end of the cable. If the system has a Video Distribution Amp the other end will be at the amp. If not so equipped, the cable will have to be traced back to its connection point. Cable may be verified by performing a continuity check, or inserting a spare, known good cable in its place. Repair or replace cable as necessary. Remove Monitor, check continuity on coax cable that extends from the rear of the unit. Repair or replace as necessary. If replacing suspect monitor corrects the problem. Repair or replace the Monitor. Video displays noise or lines across screen, all monitors. VCP has dirty video heads. Defective tape. Clean heads with a high quality wet style VHS cleaning tape. *Unit may require professional cleaning. Try a different tape that is known to be good and/or try tape in a different video machine. Defective VCP (model may vary). If cleaning does not correct the problem, repair or replace unit. Form: TS G Series Rev A TS-10

112 VCP does not function remotely from the Control Head (700227). Video System not operated correctly Defective or improperly installed VCP to Control Head Cable (511605). Defective Control Head (700227). Defective VCP (models may vary). Control Head must be placed in the Video mode by depressing the VIDEO button. Display will indicate "VID". Check cable connections at the rear of the Control Head (700227), and at the rear of the VCP. If possible perform a continuity test on the cable. Repair or replace cable as necessary. Activate the Video System. Operate the VCP directly from its front panel controls. If unit functions correctly, and the VCP to Control Head Cable (511605) has been checked, Repair or replace the Control Head (700227). It may be difficult to determine if problem originates in the VCP or the Control Head. If VCP cannot be operated directly from its front panel controls, or replacing the Control Head does not correct the problem, repair or replace the VCP. As some system configurations may vary, depending on the exact equipment and/or options that have been installed, please contact Radio Engineering Ind. directly ( ) if there are any further questions or problems that might arise.
