TP112 2-WAY SPEAKERS
Congratulations on your purchase of an excellent, high performance loudspeaker system from MTX! We
are confident that your purchase will bring you years of listening pleasure.
MTX’s TP112 consists of a single 12” woofer matched with our X-radial designed horn loaded high
frequency tweeter designed to provide uniform sound dispersion, and coverage area, with excellent sound
quality. Your TP112 speaker is designed to perform equally well in many different applications, including low
to mid level live sound reproduction, public address, karaoke applications, or mobile entertainment. The long
excursion woofer and horn-loaded tweeter with high frequency protection circuitry make your TP112 suitable
for voice or music.
Your speakers carrying handles, mounted to a strong, lightweight cabinet make it easily portable to use
anywhere you need it. The rugged corner braces allow for upright positioning and interlock for secure stacking
of multiple cabinets. The versatile 5-way binding posts and 1/4" phone jack inputs make it easy to connect to
any amplifier. You can use a single speaker for mono or connect a pair to a stereo amplifier for a stereo pair.
WARNING: To avoid injury, DO NOT SUSPEND the enclosure.
AMPLIFIER CONSIDERATIONS
Your speaker system specifications list RMS power and Peak power ratings. Power amplifiers are also
typically rated using RMS power, which is an indication of the power level an amplifier is able to continuously
deliver to a loudspeaker without damage or distortion to the amplifier. Consult your amplifier owners manual
to confirm power output at the rated impedance at which your amplifier will be operating with the speakers
connected. These ratings should be considered when selecting the best amplifier to power your system.
For general use, amplifier output should match or exceed the RMS rated power of the speaker system.
WARNING: Overpowering could cause serious damage to the loudspeaker.
HOOK UP
Your TP112 comes equipped with 5-way binding posts and 1/4” phone jacks for easy connection depend-
ing on your needs. CAUTION: Be sure your amplifier is turned off before you make any wire connections.
5-Way Binding Posts
Use color coded, two conductor or stranded, twisted pair wire to connect your speaker to an amplifier
using the 5-way binding posts. Each has two individual conductors covered with insulation, and are often
marked to help you make the proper connections. Insulation on one side of the wire might have a ridge or
colored stripe. Or, the two conductors may have different color insulation (red and black, for example). Be sure
to connect (+) on the speaker to (+) on the amp, and (-) on the speaker to (-) on the amp.
1.) Separate the conductors at each end for about two inches.
2.) Strip away 1/2” of insulation from the end of each conductor.
3.) Unscrew the positive (+) terminal and insert the (+) stripped end of a con-
ductor wire into the hole on the side of the terminal post.
4.) Hand tighten the terminal to secure the wire in place.
5.) Connect the conductor wires other stripped end to the amplifiers (+)
terminal.
6) Repeat steps 3-5 to connect the speaker to the amplifier’s negative (-)
terminals.
1/4” Phone Jack
Instead of using the speaker’s terminal posts, you can use the 1/4” phone jack to make the connection.
If your amplifier has an 8 ohm phone jack, you can use speaker cable that has a phone plug on each end to
connect the speaker’s 1/4" jack to the amps phone jack. Or, if your amplifier does not have an 8 ohm phone
jack, you can use speaker wire that has a phone plug on one end to connect your speakers 1/4" jack, and
stripped ends to connect to your amplifiers output terminals.
Connecting two speakers to a STEREO amplifier
You can connect two TP112's to a stereo amplifier for stereo sound. Connect one speaker’s positive
(+) and negative (-) terminals to the amplifier’s corresponding positive and negative left speaker terminals.
Connect the other speaker’s terminals to the corresponding right speaker terminals. NOTE: For best bass
response, it is extremely important to connect (+) on the speaker to (+) on the amp, and (-) on the speaker
to (-) on the amp.

High Frequency Protection Circuit
Your TP112 is equipped with high frequency protection circuitry, which is designed to protect your
speaker’s tweeter from accidental overpowering. The protection circuit is designed to “turn on” when the
signal (music) being sent to the speaker is reaching levels that could cause serious damage. There will be a
noticeable reduction in your speaker’s high frequency output, which lets you know that the protection circuitry
is working. When the music level is reduced to a safe level, the speaker will automatically return to normal
operation.
