Frequently Asked Questions - TX12F MARTIN

How do I connect the TX12F to an amplifier?

Use the Speakon connector on the speaker. Connect amplifier positive (+) to pin 1+ and negative (-) to pin 1-. Ensure correct polarity for optimal bass response.

What kind of speaker cable should I use?

Always use high-quality speaker cables. For 8 ohm loads, 2.5 mm² (13 AWG) cable works up to 30 m (100 ft). For longer runs, use thicker cable (e.g., 4.0 mm² for 60 m).

Can I fly the TX12F?

Yes, it has integrated flying points. Use genuine Mach M10 eyebolts (P/N 93940002) with a certified load of 4 tons. Rigging must be done by qualified personnel only.

What is the horn protection feature?

If the compression driver reaches maximum power, a protection circuit reduces signal to prevent damage. It automatically restores when current returns to safe levels.

How do I use the TX12F with a TXS18 subwoofer?

Connect the subwoofer’s high-pass output to the TX12F input. The sub has a built-in high-pass filter that protects the top-box woofer from over-excursion.

What is the impedance when linking multiple TX12F speakers?

Each additional speaker in parallel drops impedance. Two TX12F in parallel give 4 ohms. Ensure your amplifier can handle the total load.

What happens if I reverse polarity?

Reverse polarity causes a strong decrease in bass output and loss of mid/high frequency focus. Always match + to + and - to -.

How do I clean the TX12F?

Use a dry, soft cloth to wipe the cabinet. Do not use abrasive cleaners or water. The grille can be vacuumed gently to remove dust.

Can I replace the compression driver?

Yes, replacement parts are available from Martin. Refer to the service manual for proper installation. The crossover wiring diagram is provided in the user manual.

What is the recommended amplifier power for the TX12F?

For best performance, use an amplifier that delivers 250-500 watts RMS per channel into 8 ohms. Do not exceed the program power rating of 500 watts.

DESIGN CONCEPT

The TX line from Mach is a complete series of professional speakers that borrows may design features from the larger Mach speakers. The speakers in the TX line deliver clean, loud, and dynamic sound in a rugged, easy to handle package.

Features include a heavy 1.5 mm steel grill with maximum air-to-metal ratio, protective metal corners and integrated handles. The cabinets are made of high quality MDF that is highly resistant to humidity and include excellent inner damping for improved clarity.

The top-boxes are easily placed in arrays due to their 15^irc trapezoidal shape. They feature our customized 1^irc compression driver with a specially designed 90^irc × 40^irc horn, which utilizes the WaveShaper technology from the larger Mach models, ensuring excellent dispersion control and clarity. All TX models feature a professional Speakon terminal with link option.

For additional sub-bass output, the speakers in the TX line can be supported by the TXS18, a reflex loaded subwoofer with stackable corners and integrated high-pass filter. The high-pass filter enables you to operate two subs and top-boxes with one amplifier. When connecting the TX12F or 15F through the high-pass output, the top-box woofer is protected against overexcursion.

The TXS18 also features an integrated aluminium top-hat adapter that enables you to place the TX12F or TX15F above the subwoofer with a speaker pole (P/N 93943004).

CONNECTIONS

All models in the TX line are connected through the 1+/1-pins on the Speakon terminal. For correct polarity, connect the red (+) terminal on the amplifier to 1+ on the speaker. Likewise, connect the black (-) terminal on the amplifier to 1- on the speaker. If one speaker is operated with reverse signal polarity, the result is a strong decrease in bass output and lack of focus in the mid/high frequencies.

When using the high-pass output from the sub-woofer, simply link from the high-pass output on the sub to the input on the speaker. Pin configuration is stated on the label. Please refer to the recommended amplifier sizes in the specifications on the last page. Do not connect the subwoofer high-pass output to the amplifier output, as this will cause damage to the amplifier.

All models feature a Speakon speaker terminal with link option. This option allows two or more speakers to be operated in parallel from one amplifier.

When using the link output option, be aware that impedance drops with each additional speaker connected through the link terminal. The impedance is 4 ohm when two TX top-boxes are

Always use high quality speaker cables. Poor cables reduce sound quality and degrade speaker and amplifier reliability. Please refer to the following table for recommended cable lengths.

Cable size/load 8 ohm	4 ohm 2 ohm
1.5# (15 AWG)	15 m (50 ft.)	7.5 m (25 ft.)	4 m (13 ft.)
2.5# (13 AWG)	30 m (100 ft.)	15 m (50 ft.)	7.5 m (25 ft.)
4.0# (11 AWG)	60 m (200 ft.)	30 m (100 ft.)	15 m (50 ft.)

FLYING THE SPEAKERS

Warning! Rigging the speakers shall be done by qualified personnel only.

The top-boxes in the TX line feature an integrated flying system. Two flying points in the top plate and one in the rear panel make it easy and fast to fly the speaker and control the tilt. To fly the speaker, simply remove the M10 bolts in the top and rear and replace them with the genuine Mach M10 eyebolts (P/N 93940002), which have a certified load of 4 tons.

HORN PROTECTION

If this happens, the compression driver has reached its maximum power handling level. Do not increase the high frequency level on the EQ or the tone control on the mixer. This may damage the compression driver. If higher output is required, more or larger speakers are required.

When volume is decreased and current returns to a safe level, the protection circuit automatically restores full signal to the horn, and the audio output returns to normal.
