DESCRIPTION: MEYER SOUND MSL-4P AND 650P (1999) (S#: 99270910/99270885/99270040/99354143/99270042/99354148) SUPERB (8-9)

FEATURES: IN THIS SET THERE ARE : 4 X MSL-4P, 2 650P, 6 X MTG-4 TOP GRID AND 2 X MTGS SPREADERBAR.

MSL-4P IS CARPETED AND COMES WITH L-TRACK
650P IS CARPETED.

MTG-4 TOP GRID, MSL-4/DS-4P

THE MTG-4 IS USED FOR ARRAYING TYPE 4 (MSL-4 AND DS-4P) LOUDSPEAKERS FITTED WITH L-TRACK OR WITH THE RFK-1 RETROFIT FRAME KIT. THE FRAME’S RETRACTABLE ARMS ARE ADJUSTABLE, EVEN WHILE THE SYSTEM IS UNDER LOAD. LOUDSPEAKERS CAN BE ARRAYED AT HORIZONTAL ANGLES OF 15, 18.75, 22.5, 26.25 AND 30-DEGREE SPLAY ANGLES.

MTGSB-4B TOP GRID SPREADER BAR, MSL-4/DS-4P

USED TO SUSPEND TWO MTG-4 TOP GRIDS FROM A SINGLE MOTOR POINT. INCLUDES ALL NECESSARY SHACKLES AND CONNECTING LINKS. SIX PICK UP POINTS ARE PROVIDED AT EACH END OF THE BAR TO ALLOW THE ADJUSTMENT OF SPREAD BETWEEN VERTICAL COLUMNS. THIS PART REPLACES THE MTGSB-4 SPREADER BAR
-------------------------------------------------
THE MEYER SOUND MSL-4 IS A HIGH-Q, ARRAYABLE LOUDSPEAKER DESIGNED FOR A WIDE VARIETY OF MEDIUM- TO LONG-THROW APPLICATIONS. THE MSL-4’S TIGHTLY DEFINED COVERAGE PATTERN ALLOWS SEAMLESS INTEGRATION INTO ARRAY CLUSTERS, WHICH MAY BE TIGHT-PACKED FOR LONG THROW OR SPLAYED FOR BROADER COVERAGE.

THE MSL-4’S BUILT-IN POWER AMPLIFIER AND CONTROL ELECTRONICS ARE CONTAINED IN AN EASILY ACCESSIBLE, FIELD-REPLACEABLE MODULE. THE AMPLIFIER, A CLASS AB/H DESIGN WITH COMPLEMENTARY MOSFET OUTPUT STAGES, PRODUCES PEAK OUTPUT OF 1240 WATTS (620 WATTS PER CHANNEL). THE INTEGRATED CONTROL ELECTRONICS INCLUDES TRUPOWER LIMITING FOR DRIVER PROTECTION, AS WELL AS ACTIVE PHASE CORRECTION CIRCUITS TO MAINTAIN EXCEPTIONALLY COHERENT PHASE RESPONSE. SUPERIOR COMMON-MODE REJECTION FROM LASER-TRIMMED DIFFERENTIAL INPUTS ALLOWS VERY LONG SIGNAL RUNS. AN INTELLIGENT AC POWER SUPPLY AFFORDS AUTOMATIC VOLTAGE SELECTION, EMI FILTERING, SOFT CURRENT TURN-ON AND SURGE SUPPRESSION TO ENSURE SYSTEM STABILITY AND LONG-TERM RELIABILITY.

ALL COMPONENTS ARE HOUSED IN A RUGGED, MULTI-PLY HARDWOOD CABINET WITH A BLACK TEXTURED FINISH. THE MSL-4 COMES STANDARD WITH SIX AIRCRAFT PAN FITTINGS (RING AND STUD), WITH QUICKFLY RIGGING OPTIONAL.

THE MSL-4 IS COMPATIBLE WITH MEYER SOUND’S RMS REMOTE MONITORING SYSTEM.

------------------------------------------------
The Meyer Sound 650-P is a high-powered subwoofer for sound reinforcement applications. The 650-P provides extended low-frequency power bandwidth, handling high continuous operating levels and extreme transient information with minimal distortion and response extending to 28 Hz.

The 650-P houses two Meyer Sound long-excursion 18-inch drivers in a tuned, vented cabinet. An integral two-channel class AB/H amplifier with complementary power MOSFET output stages supplies total peak output of 1240 watts (620 watts/channel). TruPower limiting technology ensures maximum driver protection, minimizing power compression and permitting high constant output. An Intelligent AC power supply affords automatic voltage selection, EMI filtering, soft current turn-on and surge suppression. Phase-corrected, active signal processing circuits maintain excellent performance and reliability, and a laser-trimmed differential input with high common-mode rejection facilitates long line-level signal runs using shielded, twisted-pair cable.

The 650-P cabinet is constructed of multi-ply hardwood and coated with a textured, weather-resistant black finish. The 650-P is compatible with Meyer Sound’s RMS remote monitoring system, which provides comprehensive monitoring of system performance parameters over a Windows-based network.
