Page 3 - SAFETY SUMMARY

3 E NGLISH • To reduce the risk of electric shock, disconnect the unit from the AC mains before installing audio cable. Reconnect the power cord only after making all signal connections. • Connect the unit to a two-pole, three wire grounding mains receptacle. The receptacle must be connected to a fu...

Page 4 - AC POWER

The Meyer MTS-4A self-powered loudspeaker is a compact, self-contained, full-range system suited for clubs and small theatres (throw distances less than 100 ft). Its trapezoidal shape facilitates array design that maximizes coverage and SPL for the size of the array. Since all frequencies are produc...

Page 6 - AUDIO INPUT

The MTS-4A presents a 10 k Ω balanced input impedance to a three-pin XLR connector wired with the following convention: Pin 1 220 k Ω to chassis and earth ground (ESD clamped) Pin 2 Signal Pin 3 Signal Case Earth (AC) ground and chassis Shorting an input connector pin to the case can form a ground l...

Page 7 - RIGGING

7 RIGGING compressed air to clear dust from the grill, filter, fans, and heatsinks. Make sure that the air ducts are clear and that there is at least six inches clearance for exhaust behind the cabinet. Two variable-speed primary fans run continuously with an inaudible operating noise of 22 dBA at 1...

Page 8 - MEASUREMENT AND SYSTEM INTEGRATION TOOLS

8 It is essential that even the most carefully assembled sound systems be analyzed with precise measurement tools. We recommend using the Meyer Sound SIM® System II Sound Analyzer 1 and CP-10 Parametric Equalizer 2 to • assist the process of choosing and configuring speakers;• measure propagation de...

LD-1A WITH F LOWN MTS-4A AND CQ; 650-P ON THE F LOOR This example shows the LD-1A integrating a complete system of self-powered speakers for a large venue. Although channels 1, 3, and 5 constitute half of the system, channels 2, 4, and 6 can be used with identical connections to create the other hal...

Page 10 - ARRAY DESIGN

We do not recommend using phase poppers to analyze driver polarity. The phase response for all drivers varies, to some degree, over the frequency range in which it operates. Since the phase popper, a popular but inaccurate tool, does not discern variations in phase response with respect to frequency...

Page 11 - SPL

A RRAY D ESIGN FOR L OW F REQUENCIES Since the MTS-4A contains sub and low frequency drivers, in addition to mid and high drivers, array design for the MTS-4A must incorporate the different array response of high and low frequencies. The beam width for a single speaker widens as the frequency decrea...
