Welcome and Thank You for Selecting ADA
The ADA PTM-3245 power amplier is a major breakthrough in power amplier technology. Hand
crafted in the United States to the strict quality and performance standards established by Audio
Design Associates, the PTM-3245 is the rst thirty-two-channel power amplier ever designed for
multichannel applications.
At ADA, we have been designing and building high-performance audio components for use in custom
installation applications for over twenty-ve years. We’re proud to offer this exceptional audio component
that will provide many years of enjoyment and dependability.
The PTM-3245 can be congured in many different ways and can also be programmed for automated
operation. We strongly encourage you to read this entire manual to learn all of its advanced features
and capabilities and how to properly connect it to your specic system.
Keeping Records for Future Reference
Record the serial number located on the back of your amplier in the section below. Also note your
dealer’s name, phone number, and date of purchase. We recommend that you keep your purchase receipt
with this manual you may need to refer to this information in the future.
Serial #: ______________________________ ADA Dealer: ___________________________
Phone Number________________________
Date of Purchase: ________________________
Unpacking and Inspecting the PTM-3245
Unpack your PTM-3245 from the shipping carton and remove the enclosed AC power cord. While
you are unpacking the amplier, inspect it thoroughly for possible shipping damage. If you see any,
contact ADA for further instructions. If possible, save and store both the carton and the packing inserts
for possible future transport.
Placement Guidelines for Your PTM-3245
Power ampliers are usually heavier and generate more heat than other components. To avoid damage
to the PTM-3245 or other equipment and to reduce risk of re, follow these guidelines:
• Do not obstruct the cooling fan or any of the vent openings.
• Do not block the front of the PTM-3245 behind closed cabinet doors during use.
• If you have ordered the Select version of the PTM-3245 for shelf mounting, place the
PTM-3245 on a separate shelf that will adequately support its weight.

Rack Mounting Your ADA PTM-3245
When mounted in a in a standard 19" equipment rack, the PTM-3245 chassis and front panel height
occupies three rack spaces (5 1/4" or 176 mm). A single standard rack space allows 1-3/4" vertical inches
in a 19-inch wide equipment rack. This measurement standard was developed by the EIA (Electronic
Industries Association) so manufacturers of electronic components and equipment racks could build
products in standardized heights that would t in a uniform space.
We strongly recommend that you have someone hold the PTM-3245 in place while you screw it into
the rack. You should use nylon shoulder washers in front and behind the faceplate this will help the
unit from scratching and also prevent ground loops.
Please call ADA if you need additional advice about the placement or mounting of the PTM-3245.
Input Connections to the PTM-3245
The input connections on the rear panel of the PTM-3245 are labeled to correspond to sixteen pairs.
This makes it easy to identify each two-channel stereo zone. Zones 1-8 are located along the top row
and zones 9-16 are located along the bottom row. If you plan to split any stereo pairs for mono operation,
we recommend you keep the mono channels grouped for easy identication.
Required Input Cables:
You will need one shielded interconnect cable terminated with RCA plugs on each for each channel of
the PTM-3245 you plan to use or a shielded interconnect cable for each two-channel stereo zone.
IMPORTANT NOTE: Do not use “directional cables” when connecting the PTM3245 to a controller or
preamplier. These cables often leave the shield disconnected at one end, which can cause ground loops
and subsequent 60 Hz hum. Directional cables are usually labeled with arrows along the insulation to
identify which end to connect to the source.
Recommendations Before Connecting Inputs
• Leave the AC cord on the PTM-3245 disconnected until you have made all the other
connections
• Make sure that all your cables are long enough so they are not strained or stretched once they
are connected.
• Label the interconnect cable to correspond to the channel of the multiroom controller or preamplier.
This procedure will save time in case troubleshooting is necessary.

Terminating the Detachable Speaker Connectors
The PTM-3245 includes a detachable high-current speaker connector for each channel. These connectors
will accept wire down to AWG 12. To terminate the speaker connectors, follow these steps:
1. Strip just enough insulation from the speaker wire to expose 1/4" of bare wire to t into the
connector.
2. Loosen each of the four set screws on each connector with a small (1/8" wide) at blade screwdriver
enough to insert the stripped bare speaker wire.
3. Before inserting the wire into the connector, twist all its strands tightly to prevent strays that could
cause a short circuit. You may want to “tin” the stripped wire with solder to prevent it from fraying
and oxidizing.
4. Insert the stripped bare wire into the connector. Refer to the drawing below for correct speaker
polarity and channel designation.
5. Label the speaker cables to identify them with their corresponding zone. This procedure will save
time in case troubleshooting is necessary.
6. Tighten the set screws rmly, but not over tighten.
Correct Speaker Polarity is Important
Polarity refers to the positive (+) and negative (–) speaker connections. Speaker wires are coded with
printing or a ridge on the insulation on one of the leads so you know which lead was connected to the
+ and – terminals at the other end. This coding will help you keep the + and - polarity consistent for all
channels of the PTM-3245. The detachable speaker connectors used for the PTM-3245 are numbered
to correspond to the following code for all channels:
Positive (+) Left Channel Terminal:
1
Negative (-) Left Channel Terminal: 2
Negative (-) Right Channel Terminal: 3
Positive (+) Right Channel Terminal: 4
Plugging the Speaker Connectors into the PTM-3245
Once you have terminated the speaker wire to the detachable female connectors, plug them into the
corresponding male rear panel connectors on the rear panel of the PTM-3245. The connectors are
keyed so they can only be inserted one way. Never try to force the connectors into place.

Providing Power to the PTM-3540
AC Power Connections
Before connecting the AC cord to the PTM-3245, remove power to all the components in your audio
system. Plug the female end of the AC cord to the AC receptacle on the rear of the amplier. Plug the
male end of the AC cord to an AC outlet or power strip.
Plug the PTM-3245 into the same AC wall outlet or power strip that powers your other audio
components, especially the system controller or preamplier. Having all the audio components on the
same power circuit helps prevent hum caused by possible ground loops.
The PTM-3245 can be powered on manually from the front panel power switch. Additionally, each
channel pair or zone can automatically triggered on with a 12 Vdc trigger from the ADA Suite 16 or
other trigger source. There are two rear mounted DB-9 connectors on the rear panel for this purpose.
Manually Powering the PTM-3245
To set up the PTM-3250 for manual power control, set the trigger bypass switch to the upper Bypass
Trigger position. In this mode, the amplier can only be turned on and off from the front panel power
switch. The PTM-3245 can also be turned on from an external AC source such as the ADA ACC-48
Quad AC Controller.
Automated Zone Power Control of the PTM-3245
To set up the PTM-3250 for automated power control for each zone, set the trigger bypass switch to
the lower Zone Triggers switch. In this mode, each channel pair or zone can be turned on independently
of the other channels with a 9-12 Vdc trigger source applied between ground and the corresponding
pins on the DB-9 connectors on the rear panel.
If you are controlling the PTM-3245 with the ADA Suite-16 (which other ADA system), you only
need to connect a ribbon connector between the Zone trigger output of the P-16 and the trigger inputs
of the PTM-3245. If you are using a different type of triggering source, you can apply 9-12 Vdc to the
corresponding pin of each zone you want to activate.

AC Voltage Selection Switch
The PTM-3245 can operate on either 110-120 Vac or 220-240 Vac operation. When you purchased
the amplier, the rear panel voltage selector switches were preset for the proper voltage in your area.
Nevertheless, it’s wise to double-check it before plugging into an AC outlet. If you move to a location
with a different line voltage, you can easily convert the PTM-3245.
For 110-120 Vac Operation: Slide both voltage selector switches in their uppermost position until
the indent on the switch lines up with the 115 V label on the rear panel. In this position, the 115 V
label on the selector switch will also be visible.
For 220-240 Vac Operation: Slide both voltage selector switches in their lowermost position until
the indent on the switch lines up with the 230 V label on the rear panel. In this position, the 230 V
label on the selector switch will also be visible.
Maintaining Your ADA Amplier
Your ADA PTM-3245 power amplier requires no periodic maintenance and has no user-serviceable
parts inside. To avoid the risk of electric shock, do not remove its top cover. The amplier’s exterior can
easily be cleaned with a soft cloth pre-moistened only with a few drops of water or glass cleaner.
Power Fuse
There are two fuse posts on the rear panel of the PTM-3245 labeled Standby and Main. In the event of
a power surge, voltage spike, or internal failure, one or both of these fuses may blow. If the PTM-3245
stops operating, check both of these fuses. Always replace the fuses with the original value. Replacing fuses
with higher than rated values may cause serious damage that will not be covered under warranty.

Warranty and Returning the PTM-3245 for Factory repair
ADA power ampliers are under warranty for here (3) years effective upon the dealer’s receipt of the
product. If ADA determines that you should send your amplier to ADA for factory repair, you will be
given a Return Authorization (RA) number. This RA number must be clearly marked on the outer carton.
IMPORTANT: Enclose a copy of your original purchase receipt to validate warranty coverage.
It is the dealer’s responsibility to pay for shipping to ADA. Be sure to ship the unit with adequate
insurance. After repair under warranty, the unit will be returned to you via prepaid within the continental
United States.
Important Notice - Shipping the Amplier to ADA
Before shipping the unit, you MUST re-pack the unit into its tted molded foam insert and its original
carton. If you do not have the original packing cartons and foam inserts, call us for new packing materials
that we can provide to you for a nominal charge. Use of any other carton and packing materials will
probably result in shipping damage, and refusal of the unit. Common carriers such as UPS seldom
pay claims for damage incurred during shipment when a product is surrounded only with Styrofoam
“peanuts” or otherwise improperly packed.
We cannot stress enough the importance of properly packing your amplier. Shipping damage resulting
from inadequate packing can cost you a lot of money and signicantly increase the time required for
repair. Ship the unit with adequate insurance. After repair under warranty, the unit will be returned to
you via prepaid UPS within the continental United States.
