NTRODUCTION

DE S I G N A P P L I C A T I O N S

The in-fill speakers for the Mach installation series have been designed for commercial

venues such as cafés, clubs, department stores, conference rooms, and hotels, that require

high-fidelity in-fill sound.

The goal of the in-fill speaker design is to provide true hi-fi performance with high speech

intelligibility in a compact package. As background noise in these venues is typically

located in the mid-frequency area, the in-fill speakers are acoustically optimized for clarity

and openness in the mid-range.

The M42i and M62i are top-boxes that can be supported by the M208i sub-woofer or the

bass output of the venue’s main PA system.

The M208i is a stereo subwoofer with an integrated high-pass filter that enables the sub

and two top-boxes to be powered by one amplifier. It has been made as compact as

possible using the bandpass principle, which maximizes the output-to-size ratio.

The M68i is a full-range speaker with usable bass-output down to 60 Hz; it can be used as

a stand-alone box without subwoofer support.

All Mach in-fill top-boxes have wide, even dispersion that ensures good coverage in low-

ceiling applications.

FE A T U R E S

• Thermal protection circuit on all tweeters

NSTALLATION

HANGING BRACKETS

Custom brackets with horizontal and vertical tilt are available for all top-boxes.

• Black hanging bracket for M42i/M62i............................................................P/N 93943001

• White hanging bracket for M42i/M62i............................................................P/N 93943002

• Special multi bracket for M68i........................................................................P/N 93943006

The MIW62 comes with a mounting bracket for ceilings as illustrated below.

CONNECTIONS

Always use high quality speaker cable for the best sound quality and system performance.

All in-fill models are easily connected using push terminals. For correct polarity, connect the

red (+) terminal on the amplifier to the red terminal on the speaker. Likewise, connect the black

(-) terminal on the amplifier to the black terminal on the speaker. If one speaker is connected

with reverse polarity, the result is a strong decrease in bass output and lack of focus in the

mid/high frequencies.

If supporting the in-fill top-boxes with the M208i subwoofer, connect the high-pass output on

the M208i to the top-box input. Connect only one pair of top-boxes to the subwoofer output.

Important! Do not connect the subwoofer high-pass output to the amplifier

output: this will cause damage to the amplifier.

MIW62 INSTALLATION

As a rule of thumb, correct coverage is obtained by spacing MIW62’s at a distance similar to the

height of the room.

With the 100V module included, the output of the speaker can be controlled individually by

connecting it to the - (minus) terminal and to one of the output options shown below:

The cut-out dimensions for MIW62 are 278 x 190 mm (11" x 7½").

The minimum depth required is 80 mm (3.15") without the 100V module and 100 mm (4") with

100V module.

PERATION

TWEETER PROTECTION

The tweeters are protected by a thermal protection circuit that increases impedance when the

current exceeds a safe level. The increased impedance reduces current to the tweeter, thus

protecting it against damage. The audible result is a decrease in high-frequency output. If this

happens, do not increase the high-frequency level on the EQ or tone control on the mixer: the

tweeter has reached its maximum power handling capacity. If higher output is required, more or

larger speakers are needed.

When volume is decreased and current returns to a safe level, the protection circuit

automatically restores full signal to the tweeter and the audio output returns to normal.
