CAUTION:
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT
REMOVE COVER (OR BACK).
NO USER SERVICABLE PARTS INSIDE. REFER SERVICING TO
QUALIFIED SERVICE PERSONNEL.
WARNING:
TO REDUCE THE RISK OF ELETRIC SHOCK, DO NOT EXPOSE
THIS APPLIANCE TO RAIN OR MOISTURE.
13 For added protection of the TV set during a lightning storm or when the TV set is to be left
unattended for an extended period of time, unplug it from the wall outlet and disconnect
the antenna. This will prevent damage to product due to lightning storms or power line
surges.
14 A TV set and cart combination should be moved with care. Quick stops, excessive force,
and uneven surfaces may cause the TV set and cart combination to overturn.
15 Unplug this TV set from the wall outlet and refer servicing to qualified service personnel
under the following conditions:
A. When the power cord or plug is damaged or frayed.
B. If liquid has been spilled into the TV set.
C. If the TV set has been exposed to rain or water.
D. If the TV set does not operate normally by following the operating instructions.
Adjust only those controls that are covered in the operating instructions as improper
adjustment of other controls may result in damage and will often require extensive work
by a qualified technician to restore the TV set to normal operation.
E. If the TV set has been dropped or damaged in any way.
F. When the TV set exhibits a distinct change in performance — this indicates a need for
service.
16 Do not attempt to service this TV set yourself as opening or removing covers may
expose you to dangerous voltage or other hazards. Refer all servicing to qualified service
personnel.
17 When replacement parts are required, have the service technician verify in writing that the
replacement parts he uses have the same safety characteristics as the original parts. Use
of manufacturer’s specified replacement parts can prevent fire, shock, or other hazards.
18 Upon completion of any service or repairs to this TV set, please ask the service technician
to perform the safety check described in the manufacturer’s service literature.
19 When a TV set reaches the end of its useful life, improper disposal could result in a picture
tube implosion. Ask a qualified service technician to dispose of the TV set.
20 Note to CATV system installer.
This reminder is provided to call the CATV system installer’s attention to Article 820-40 of
the NEC that provides guidelines for proper grounding and, in particular, specifies that the
cable ground shall be connected to the grounding system of the building, as close to the

FUNCTIONS
Level Controls - Allows any of the channels to be adjusted independently to raise or lower the output of each channel.
BUS(L.R)*LINE Switch - Allows each channel to play a variety of dierent inputs. Depending on the switch posion the channel
amplies the signal connected to the BUS input and its own LINE input. Bus switch also includes a L and R posion which is used to
direct the channel to play the le signal from input “L” or right signal from input “R”.
POWER MODE SELECTION
There are three ways to turn the amplier on and o:
1. Manual - Use this selecon when you wish to manually turn the amplier on and o by using the front power buon.
2. Trigger - Use this selecon to turn on the amplier when it receives voltage (3-24V A/C or D/C) from an external source and turns
o once that voltage has stopped. The voltage source must be connected to the trigger-input jack on the back of the amplier.
3. Audio Sense - The amplier will automacally turn on when the amplier’s main input receives an audio signal. At the moment
that either the le or right input jacks receive a signal, the amplier will automacally turn on. Once the signal stops, the amplier
automacally goes into stand-by mode aer 3 minutes.
BRIDGE MODE
To bridge two adjoining channels move the switch marked “BRIDGE” to the “ON” posion. The output of the combined channels can
then be used to power one speaker. Do not connect more than one speaker to the outputs of the bridged channel.
REMOTE POWER ON
3-24V DC/AC Trigger in - 3-24V AC or DC input to trigger power up with voltage from another device, such as a receiver. The voltage
source must be connected to the trigger-input jack on the back of the amplier.
12V DC Control Out - The 12V output jack on the back of the amplier can be used to turn on a variety of components equipped to
be acvated when they receive a 12V DC output.
