Description of the C-range speakers

The range can be divided into 3 different groups of products:

• CN Near-field top boxes and full-range speakers for medium SPL applications where ultimate sound quality is required at low-to-medium SPL with low-to-medium projection and wide dispersion.
• CM Medium-throw top boxes and full-range speakers for high SPL applications where ultimate sound quality is required at medium-to-high SPL with medium projection and more focused dispersion.
• CW Dedicated installation subwoofer to complement CN and CM top boxes.

To illustrate the difference between a CN box and a CM box consider two typical installations:

• A small club with a large bar and entertainment area plus a small dance floor with a low ceiling.
• A medium-to-large dance club with a large dance floor and surrounding seating areas, a high ceiling, and a live DJ.

In the small club, the ideal solution has good, tightly controlled distribution, high-quality warm sound at low-to-medium SPL, small cabinet size but still an output high enough for an intense dance experience. The system will typically run at varied output levels between 30 and 80 % of maximum output. In the larger dance club high SPL, clean, solid sound with minimum distortion and extreme endurance is an absolute must. Good sound quality at low to medium SPL is less of an issue as the system will always run at close to 100 % output. In many venues, the ideal solution will be a mixture of CN and CM boxes for different sections of the venue thus the new C-range enables the building of a complete solution customized for the specific requirements of most customers.

Your new Mach C-range speaker is one of the most versatile products on the market and every possible effort has been made to make it quick and easy to install your product. The many different installation options available will be described below.

Mounting points on the cabinet
The mounting points on the CN and CM cabinets are shown in the illustration below.

In total the cabinet has 18 mounting points four of which are vertically adjustable (A). In addition, the spider bracket has a mounting point that can be used for an eyebolt (B).

Spider bracket
All CN12 and CM12 speakers are supplied with the revolutionary spider bracket shown below.

The bracket can be mounted vertically and horizontally depending on the direction the speaker should be flown and enables easy mounting with a minimum of time and effort.

How to install your C-range speaker on the optional Multibracket
The C-range is available with an optional Multibracket that represents the optimum solution for many types of wall and ceiling installations.

Adjusting the angle

Loosen the vertical adjustment locking bolt, remove the locking pin, and adjust the bracket to the required vertical position. Replace the locking pin and tighten the locking bolt. Adjust the bracket horizontally and tighten the locking bolt underneath the arm.

Note! The Multibracket may not be used with CM15 and CM18

To mount a CN or CM cabinet on a wall please use the following procedure

1. Find the correct position on the wall and mark where the base of the bracket should be positioned
2. Take the bracket and hold the base flat to the wall at the marked position
3. Mark each hole with a marking tool or a pencil
4. Remove the bracket
5. Drill a hole of the diameter and depth appropriate for the raw plug you plan to insert
6. Insert a raw plug into each hole
7. Position the bracket so that the mounting holes align with the holes in the wall
8. Screw the bracket lightly to the wall in the corners
9. Align the bracket horizontally
10. Insert the last two screws and tighten all 6 screws appropriately. The bracket has been designed to carry a speaker no larger than the CM 12 weighing no more than 40 kg (88 lbs)

Note! Proper backing or wall structure is required

The Multibracket is extremely versatile as illustrated and enables very flexible adjustment of speaker orientation.

How to install your C-range speaker with the U-bracket
All the smaller models in the C-range are supplied with a U-bracket as standard. For many installation purposes, this bracket will be the optimum solution as it is very versatile and easy to use. Illustrated below are several ways to use the U-Bracket.

Note! The illustration shows the U-bracket for CN12 and CM12

How to mount speaker with eyebolts

• For some installations, especially of the larger speakers in the C-range, the ideal way to mount the speaker is by hanging the cabinet in a wire or chain attached to the speaker with an eyebolt.
• All mounting points use standard 10mm metric thread for maximum flexibility. To screw an eyebolt into the cabinet, first, select where to position the bolt and unscrew the blind bolt already in place. The eyebolt should be tightened with no more than 5 NM (3.7 ft-lbs).
• The certified maximum load for the standard Mach eyebolt is 4000 kilograms (8800 lbs).

Warning! Make sure that you comply with all local health and safety regulations when you fly a product.

Rotatable horn
The CM12, CM15, and CM18 feature a rotatable horn that allows the speaker to be flown vertically or horizontally and still maintain the required dispersion. The default positioning of the horn is for horizontal installation. If vertical installation is required remove the grille and unscrew the horn base-plate (On the CM12 unscrew the actual horn). The horn can now be rotated 90 degrees to achieve the required dispersion.

Horn protection
The horn features a thermal protection circuit that increases the impedance when the current exceeds a safe level. The increased impedance reduces current to the horn, thus protecting it against damage. The audible result is lower output from the horn. When this happens, do not increase the high-frequency level on the EQ or tone control, as this may cause damage to the protection circuit and possibly also the diaphragm.

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

The thermal protection is very efficient as it combines good protection with excellent sound quality. The components in the protection circuit are all linear and thus do not influence the sound when not engaged.

Connection
The C-range has a flexible and user-friendly connection module with double connectors, which gives the user the choice of using NL-4 connectors or screw terminals.

How to connect the speaker cable to barrier strip terminals
The barrier strip terminals are a quick and easy way to connect the speaker to an amplifier without using a connector. When using the barrier strip terminals you can either connect a stripped wire or fit a U-type cable shoe on the end of the wire as illustrated.

How to attach safety wire
The safety wire is attached to the speaker at one end and to the wall at the other. To mount the safety wire to the speaker please follow the procedure sketched below.

Connecting to amplifiers and system configurations
The way you connect your C-range speakers to your amplifier depends on the type of installation that you are making and the type of amplifier used.

Cables

To get the best possible performance from your C-range speaker, use a high- quality cable. Cables with high capacitance, high inductance, and high impedance have a strong negative influence on sound quality as well as amplifier reliability.

Mach Speakers A/S recommend 2×4 mm (11 AWG) or 4×4 mm (11 AWG) Mach speaker cable. This is a professional rubber cable that is waterproof and has low impedance, low inductance, and low capacitance. It also has a low sulfur content that ensures minimum cable oxidation. The cable is very soft and easy to wind. For recommended cable lengths, please see the table.

Recommended cable lengths (damping factor = 50)

Simple connection CN12
The most basic type of connection is a direct connection from one channel on the amplifier to one speaker. In this case, connect the [+] terminal on the amplifier to the [+] terminal on the speaker and the [-] terminal on the amplifier to the [-] terminal on the speaker.

Note! All configurations are illustrated with one channel.

Parallel system CN12
If you require more speakers for better sound distribution and you only have a limited number of output channels on your amplifier, you can connect more than one speaker to each channel. This can be done by linking the speakers for each channel in parallel as illustrated. However, always remember to check the minimum loading impedance specified for the amplifier. The maximum number of identical C-range speakers that can be connected to each amplifier channel is the impedance of the speaker divided by the minimum specified speaker impedance rating of the amplifier (often 4 ohms).

System configuration
For maximum flexibility, all Mach CM speakers can run either passive, using the built-in crossover, or active/bi-amped with the direct drive of each transducer. The speakers are all set up as passive from the factory, but can easily be switched over to active mode at a later stage.

Passive mode setup
Input Speakon pin 1+1-
While operating in passive mode the connectors on the terminal plate will work as shown below:

Active mode setup
Input LF 1+1- Input HF 2+2-
While operating in active mode the connectors on the terminal plate will work as shown below:

Switching between Passive and Active mode
For the CM series Mach has developed a completely new, extremely safe, and user-friendly way to switch between Passive and Active mode. The procedure is very quick and simple:

1. Unscrew the lid on the terminal plate with the two screws
2. Remove the Molex connector from the passive socket
3. Insert the Molex connector into the active socket
4. Turn the lid 180 degrees
5. Reposition the lid on the terminal plate
6. The graphics on the plate will now clearly indicate the selected operation mode

Passive mode

Parallel system in passive mode CM12, CM15 and CM18
If you require more speakers for better sound distribution and you only have a limited number of output channels on your amplifier, you can connect more than one speaker to each channel. This can be done by linking the speakers for each channel in parallel as illustrated. However, always remember to check the minimum loading impedance specified for the amplifier. The maximum number of identical C-range speakers that can be connected to each amplifier channel is the impedance of the speaker divided by the minimum specified speaker impedance rating of the amplifier (often 4 ohms).

Configuring your Mach CM system for active mode operation
The Mach CM products were designed with maximum flexibility in mind, not only in terms of mounting and adjustments but also in terms of connection and configuration. In the following, some of the most common ways of configuring your system for active mode operation will be illustrated. Please note that this manual does not go into detail about the use of the Mach 20.06 controller, but all speaker presets for the Mach CM series are preloaded in new or available for download for older controllers, making the configuration of the system quick and effortless.

Bi-amp 3-way with Subwoofer
In a bi-amp 3-way system the internal crossover is used for mid/high frequencies and the M20.06 controller is used to filter out the subwoofer signal to a separate amplifier running the subwoofer.

Bi-amp 2-way
In bi-amp 2-way configurations each transducer is driven by a separate amplifier and the system is crossed over directly by the M20.06 for 2-way full-range output.

Triple-amp 3-way
In a triple-amp 3-way system each transducer is run by a separate amplifier and all signal modulation is done by the M20.06.

Painting the speaker

The C-range cabinets are made of MDF coated with Mach Safecoat and can easily be painted to match the color scheme of your venue.

To paint your speaker please follow the procedure below:

1. Remove the front grille

2. Degrease the cabinet on all surfaces with denatured alcohol/methylated spirit
   Warning: Use of other types of cleaning chemicals can damage the cabinet and should be avoided

3. Mask all areas that should remain unpainted (tweeter, woofer, switch, terminals, reflex port, etc)

4. Paint the speaker with Etching primer 2K, P565-713, chromate-free, or a similar product

5. Let the primer dry

6. Apply paint in thin layers using a paint-spraying device

7. When spraying the grille be very careful not to fill any holes, as this will have a serious impact on sound quality

8. Let the paint dry

9. Remove masking

10. Put the grille back in place

Maintenance of speakers

• Although speaker systems normally only require very limited maintenance there are several things you can do to ensure that your Mach system sounds as good 3 years after installation as on the day you bought it:
• Never overload your system – stay within the specified limits for power handling.
• Always keep the speaker clean and dry.
• As with any electrical product, currents will accelerate the corrosion of metal surfaces. Therefore, it is recommended to check the terminals for corrosion at regular intervals, especially if the speaker is mounted in a hostile environment.

How to remove the grille
Remove the screws in the grille and pull the grille out. When replacing the grille do not over-tighten the screws.

How to change drivers/woofers
Remove the grille, then remove the screws in the drivers/woofers and pull them out. Carefully disconnect the wires and connect them to the new transducers, tighten the screws, and refit the grille.

How to remove spider bracket
Unscrew the four bolts and remove the spider and the washer, then replace the bolts in the nuts and tighten.

How to remove the terminal module
Loosen the six screws and pull the terminal out. Note the positions of the wires, then carefully disconnect the wires from the transducers.

How to change crossover
Remove the terminal, note the position of the wires then carefully disconnect the wires from the transducers. Loosen the two screws on each Speakon socket, undo the four screws from the crossover, and remove the crossover from the terminal.
