PA 64
Installation & Operation Manual
The PA for ALL applications!

IMPORTANT!
Please read all these key points to ensure the proper
connection and designed use of your PA 64. If you
have ANY questions, please call 1 888 724-5351
before proceeding!
•Basically, the PA 64 is an amplifier that is connected between the
stereo’s output and the vehicles speakers!
•DO NOT connect the vehicles speaker wires to the stereo’s
output as well as the PA 64. Remember point one… the PA 64
goes between the stereo and the speakers!
•The PA 64 is an amplifier and is NOT designed to be used with
ANY other amplifiers (e.g. being connected between the stereo
and amplifier). If done, the PA 64 will not function and it may
damage the PA 64 and / or the additional amplifiers. If you need
more amplification than the PA 64 offers, we have other PA
options to suit. Please just give us a call.
•The PA 64 is intended to be installed by a professional installer,
service mechanic, vehicle dealer or manufacturer. Do not
attempt to install this unit without confirming compatibility to
your vehicle with the manufacturer or dealer. Failure to do so
may cause damage to the PA 64, your vehicles electrical system
or void your vehicle warranty.
•Always make sure your power wires are fused at the source of
the power to protect the wires from shorts!
•Only use with Ready2Talk microphones… use of any others may
cause damage.

Now with the important warnings out of the way…
The PA 64 is designed to be the best unit for all applications, offering
a real amplifier with 4x50Watts (peak), solid state mic / stereo
switching and variable muting for both the rear RCA input and the
front 3.5mm AUX input.
It also allows the use of two microphones, hand or headset, wired or
wireless; and is the perfect PA system for Sightseeing, Shuttle,
Transit, School Bus, Church Busses, Retirement Homes, People
Movers, Boats, Trolleys, Snow Cats and Horse Carriages. Did we
forget anything? Oh yes… also an easy replacement for older PA
systems in Highway Coaches.
Use the PA 64 as a standalone PA system or in conjunction with your
factory (OEM) stereo or any aftermarket stereo / DVD player or
automated tour system by using the internal High / Low impedance
selector. Don’t forget you can connect your MP3 player though the
front AUX input.
The PA 64 can be mounted on any flat surface vertical or horizontal
and includes an optional front decal so the printing will always be the
right way around. We try to think of everything.
Want to hide it away? There is an optional RMK (Remote Mounting
Kit) and a RME (Rear Mic Extension) for a second mic when using a
step on guide.
Easy to connect, easy to use and is better sounding than any other PA
you’ve heard before. Finally, you too can sound like a radio DJ.
*sound effects and annoying side kick not included.

Note: Never increase the value of the fuse as damage may occur.
Note: The 4 x 50 Watt amplifier inside the PA 64 is designed to
accommodate a 4 –8 Ohm floating speaker load.
Note: DO NOT EXCEED a 4 –8 Ohm speaker load! If speaker load
is outside intended range, the PA 64 will blow the 10A power fuse
after a short time.
Note: The PA 64 amplifier uses a floating output. Please ensure
your speakers are not common grounded or connected to the vehicle
ground as damage will occur to the PA 64 and repairs / replacement
will not be covered by warranty.
Note: All “Speaker Connection Options” are based on the use of 4
Ohm speakers and these diagrams will offer a load range from 4 –8
Ohm to the PA 64 amplifier. If in doubt… please call 1 888 724-5351

Testing your PA 64
1. Connect your microphone to the “Mic 1” on the front of the PA
64 and / or “Mic 2” on the back.
2. Turn on the vehicle, then the PA 64 power switch (the power
light will come on), turn on the microphone and talk in to the
mic. Adjust the mic volume with the “Volume” control on the
front of the PA 64 to your desired volume.
3. Turn off the mic and turn on the stereo, adjust the radio volume
as normal to desired level.
4. Turn the “Audio Mute” control on the front of the PA 64 to half
way / 50%. (nothing will happen yet)
5. Turn back on the mic and the radio volume will mute to 50% of
what you just set. Turn the mic off and the radio will come back
up to full volume automatically.
6. You can adjust the amount of muting by turning the “Audio
Mute” control on the front of the PA 64. Full left = no muting,
full right = 100% muting.
7. When playing music from your MP3 player through the front
“AUX input”, the muting will function the same as listed above in
point #5.
Note: With the mic switch in the OFF position the front controls on
the PA 64 will not function. This is normal.
Note: When connecting your MP3 player into the front “AUX input”
the sound will blend together with the stereo. It’s recommended to
turn off the stereo when using the “AUX input” so they don’t compete.
