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.

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.

O
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.
