GENERAL SYSTEM DESCRIPTION

The JBL M9500 monitor loudspeaker system represents a refinement of the principles that have guided JBL’s high-level monitor system design over the last thirty years.

In keeping with contemporary monitoring practice, the system is essentially of two-way design. A horn-compression driver section covers the frequency range from 650Hz to20kHz. Located above and below the high-frequency section are mirror-imaged low-frequency transducers in ported enclosures. The stereo pair of loudspeakers exhibits both vertical and horizontal symmetry for effective “point source” radiation and for accurate stereophonic imaging. All transducers make use of shielded neodymium magnets, and the systems can be used in proximity to video monitors with no interference.

The M9500 system uses stand-alone dividing networks that facilitate various electronic options, including bi-wiring, tri- wiring, and biamplification. The networks are designed around the finest components available and make use of dc bias on the capacitors for greater linearity.

A single M9500 system is capable of producing sine wave out- put levels of 110 dB Lp at one meter with extremely low distortion. In terms of wide band program, this translates into levels of 120 dB Lp for the stereo pair at normal listening distances of 2 and 3 meters.

The enclosures are made of thick sections of medium- density fiberboard, liberally braced, and have an attractive, scuff-resistant finish.

Unpacking and Inspection

The complete M9500 system is shipped in eight containers, as detailed below:

2 — Lower low-frequency enclosures

2 — High-frequency/horn enclosures

2 — Upper low-frequency enclosures

1 — Dividing networks (2 networks in one package, including 6 hook-up cables and 4 9-volt batteries)

1 — Low-frequency grilles (4 in one package)

Make sure that you have all containers. Unpack them carefully and inform your JBL dealer of any sign of damage. It is recommended that you save the packaging for future use.
