An audio attenuator circuit is
also provided to enable the user
to install both the positive and
negative speaker outputs from a
J AMMA ( or similar) system
without disabling the on-board
amplifier, and to take advantage
of the quality audio amplifier sys-
tem available in large screen
TVs, thereby enhancing the use
of the system in arcades or other
large and noisy environments.
The ASC Model 121 is designed

game use. It is easy to install and
is complete with an easy to follow

means that if someone breaks
into the cabinet from the back to
try and get the cash box they will
find a piece of 3/4" plywood pro-
tecting any access to the front of
the cabinet from the back.
CERTIFIED
First, we have now received UL
certification on all of our video
products. Along with our hockey
tables, we now offer our complete
product line with UL certification
to meet the ever-changing state
and local ordinances requiring all
products that are placed in a com-
mercial environment be UL ap-
proved.
SECURITY
Along with the UL certification,
we have also made many changes
to improve the cabinet security
against break-in's. We have im-
proved the bracket and locking
design of the control panel so that
it is no longer possible to "pop"
the control from outside and steal
the boards. This new design locks
securely from the inside of the
cabinet and provides a new level
of stability and security for the
control panel. We have also iso-

RETRO
The new control panel locking
system is retrofittable to our
older HS-5 and HS-9 cabinets.
Please contact your Dynamo dis-
tributor to order these control
panel kits.
RGBffV INTERFACE
We have also developed an inter-
face board for the HS-13 big
screen cabinet. This board con-
verts the RGB signal from any
JAMMA game board to a usable
television signal. This board will
eliminate any set-up problems
that you may have been experi-
encing with the HS-13 product.
To order this board, please con-
tact your Dynamo distributor.
