Page 7: Introduction
NTRODUCTION The M3D Line Array is a part of the Meyer Sound M Series, which is a fully integrated line of loudspeakers that brings singular advantages to real-world applications. The M3D Line Array, shown in Figure 1, draws upon classic linear array principles and is a hybrid system using advanced engineering to optimize line array performance for consistent, reliable coverage. -
Page 8: Ac Power
AC voltage stays within either of two operating windows: 85-134 V or 165-264 V, at 50 or 60 Hz. Refer to Table 2 on page 20 for the M3D or Table 3 on page 23 for the M3D-Sub for detailed AC voltage requirements. -
Page 9: Current Requirements
If the M3D or M3D-Sub shuts down due to either low or high voltage, the power supply automatically turns on after three seconds if the voltage has returned to either normal operating range. - Page 10 REFER SERVICING TO QUALIFIED PERSONNEL. Y - LINE (BROWN) Figure 7. For M3D or M3D-Sub loudspeakers fitted with the VEAM multipin connector please refer to the Meyer Sound document, VEAM Cable Wiring Reference, part number 06.033.113, for the wiring conventions and pinouts for the AC, audio, and RMS connections.

Page 12: Audio Input
M3D rear panel audio input connectors The input impedance for a single M3D or M3D-Sub is 10k ohms; if n represents the number of M3D or M3D-Sub loudspeakers in an array, paralleling the inputs of n M3Ds or M3D-Subs will produce a balanced input load of 10k ohms divided by n. -

TPL activity is indicated by the LEDs on Left Front MS-418 N the user panel. The M3D and M3D Sub perform within their acoustical specifications and operate at a normal temperature if the limit LEDs are lit for no longer than two seconds, and off for at least one second. -
Page 14: M3D Peak Limiter
This circuit works for all frequencies, not just very low frequencies where the drivers are more vulnerable overexcursion. The M3D-Sub operates safely if the Exc. Clamp LED is on for no longer than two seconds, and off for one second. ANS AND The M3D uses a forced-air cooling system with four fans to prevent the amplifier modules from overheating. -
Page 15: Using And Replacing The Rain Hood
SING AND EPLACING THE The rain hood installed on the M3D user panel is provided to protect the loudspeaker’s electronics from direct exposure to rainfall. Before using the M3D, open the rain hood as described in the following procedure. -
Page 16: Removing The M3D/M3D-Sub Amplifier
Removing the M3D/M3D-Sub Amplifier If you need to remove the M3D amplifier, you must first remove the rain hood, as follows: 1. Using a #2 Phillips screwdriver, remove all eight screws from the rain hood. This will free both the rain hood and the HP-4 electronics module from the M3D cabinet. -
Page 17: Hybrid Line Arrays
For high frequencies, the M3D takes advantage of the control that wave guide horns provide. In the horizontal pattern of the array, these horns work just as any wave guide does to produce a consistent beamwidth of coverage. - Page 18 2. Overall low-frequency headroom decreases. 3. The length of the line array column is effectively shortened. The following is a sample M3D system block diagram showing one method of driving an array, along with additional fill loudspeakers and subwoofers. Digital...

M3D-Sub direction subwoofers can be used to augment the M3D line arrays. There is no polarity switch on either the M3D Line Array or the M3D-Sub directional subwoofer. Both are wired pin 2 “hot” (positive acoustic pressure when a positive pulse is applied to pin 2). - Page 21 DS-2 output. With the switch out, a full-range signal is sent to both the DS-2 and Sub outputs. Since this filter affects the DS-2 out and the SUB out the M3D-Subs need to be connected to the Mid-Hi output receiving a full range signal.
