2. INTRODUCTION
Congratulations on the purchase of your new EAW Commercial 70 Volt/100 Volt
transformer panel. These panels allow you to congure the VR Series Loudspeakers and the
CLA37 Column Loudspeaker for use in 70 Volt or 100 Volt distributed systems.
• The AC-TX64 transformer panel can be used in the VR61, VR62 or CLA37
Loudspeakers, in place of the input terminal plate.
• The AC-TX128 transformer panel can be used in the VR21 or VR51 Loudspeakers.
3. INSTALLATION
Unpacking and Inspection
Visually inspect the outside of the shipping carton and check for any shipping damage.
After unpacking, if you nd concealed damage, save the packing materials for the carrier’s
inspection, notify the carrier immediately, and le a shipping damage claim. Although EAW
Commercial will help in any way possible, it is always the responsibility of the receiving
party to le any shipping damage claim. The carrier will help prepare and le this claim.
Installation Procedure
1. Remove any external speaker wires
from your Loudspeaker’s input
terminals, and remove the six screws
securing the input panel.
2. Remove the internal wires from the
back of the input panel, and put the
input panel in a safe place for future
use.
3. Connect the Positive (white) wire
from the Loudspeaker to the white
wire from the transformer.
4. Connect the Negative (black) wire
from the Loudspeaker to the black
wire from the transformer.
5. Fit the transformer panel to the
Loudspeaker, with the transformer
inside, and secure using the six
screws from step 1. Make sure
the two wires are not accidentally
pinched.
NOTE: For the CLA37, the
transformer panel must be installed
upside down, so the transformer is
at the top, and does not interfere
with the CLA37 drivers.

4. CONNECTIONS
WARNING: To prevent the risk
of electric shock, do not connect
the loudspeaker with the amplier
switched on. Never touch the bare
wires coming from the output
terminals of the amplier when it is
switched on. When the connections
have been made, add the protective
insulated cover over the screw
terminals of each transformer
panel in your system, and over the
amplier output terminals.
• The connectors on the transformer
plate are screw terminals.
• Strip the loudspeaker wiring back
about 1/2", loosen the screw enough
to loop the wire around the shaft of
the screw (clockwise), and tighten
down the screw with a screwdriver.
• In a constant-voltage distribution
system, all the loudspeakers are
connected in parallel. This makes it
easy to add or remove loudspeakers
from the system without having to
recalculate the impedance of the
load on the amplier.
• Add up the power ratings of the taps
you are using, and make sure the
total power adds up to no more than
90% of the rated output power of
the amplier being used.
AC-TX64
• The AC-TX64
can be used with
the VR61, VR62
and the CLA37
Loudspeakers.
When using with
a 70 V distribution
system, read the
bottom row of
markings. Connect
either the 16 W, 32 W, or 64 W
terminal to the positive "+" side of
the 70 V system, and connect the
COM terminal to the negative "–"
side of the 70 V system.
• When using with a 100 V distribution
system, read the top row of
markings. Connect either the 32 W
or 64 W terminal to the "+" side of
the 100 V system, and connect the
COM terminal to the "–" side of the
100 V system.
DO NOT use the terminal labeled
“NA” in a 100 V system.
AC-TX128
• The AC-TX128 can
be used with the
VR21 and VR51
Loudspeakers.
When using with
a 70 V distribution
system, read the
bottom row of
markings. Connect
either the 32 W, 64 W, or 128 W
terminal to the positive "+" side of
the 70 V system, and connect the
COM terminal to the negative "–"
side of the 70 V system.
• When using with a 100 V distribution
system, read the top row of
markings. Connect either the 64 W
or 128 W terminal to the "+" side of
the 100 V system, and connect the
COM terminal to the "–" side of the
100 V system.
DO NOT use the terminal labeled
“NA” in a 100 V system.

5. EXAMPLES
The diagrams below show the EAW Commercial CXA 240 Paging Amplier.
This amplier has an output power of 240 W, so the sum of all the loudspeaker power
taps being used should not exceed 90% of this, i.e., 216 W.
70 V System: Use the amplier output terminals COM and 70 V, and use Class I wiring:
100 V system: Use the amplier output terminals COM and 100 V, and use Class I wiring:
