System 2000

Overview:

The System 2000 is a proven generation 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 VCR. 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 100-watt RMS per channel amplifier, capable of
driving up to twenty-six, four ohm speakers.

• Up to six, custom designed 10-inch color monitors, which incorporate a
patented, 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 recorder that allows the operator
convenient control over its functions.

Individual seat audio option. Allows each passenger to choose between

•

up to seven channels of stereo audio and one video audio channel.
Allows individual volume control of each channel.

Verify power connections to relay
and any external current protection
devices, ie fuses or circuit breakers

Control Head. Measure the Voltage
on both sides of the Video relay's
coil. The side connected to the
(510566) cable, orange wire, should
measure approximately 0 Volts. The
opposite side should measure power
(+12 or +24V depending on relay
used). Relay should energize. If
these voltages are present but the
relay does not energize, replace the
relay.
Verify that the orange wire (from
510566 cable) is connected to the
relay coil. Activate the Video
System (as previously described).
Measure Voltage levels at the relay
coil. If the orange wire does not
measure near 0 Volts (less than 1V),
and all other connections are correct,
replace or repair the Control Head
(700227).
If power is being switched by the
relay, verify that it is also present at
the parcel racks, were the monitors
connect to it. If not, repair or replace
