McIntosh XLS320, XLS360, XLS340 Important Information, Introduction, 1LD/HP Pat. No. 5,151,943

Important Information

Caution: The XLS360 Loudspeaker weight is 107 pounds (48.5kg) net. It requires two or more persons to handle safely.

1.Loudspeaker Cables of adequate size are important to ensure that there will be no significant power loss or heating. Cable size is specified in Gauge numbers or AWG (American Wire Gauge). The smaller the Gauge number, the larger the wire size:

If the Loudspeaker Cables are 25 feet (7.62m) or less, use at least 16 Gauge (AWG) wire size or larger.

If the Loudspeaker Cables are 50 feet (15.24m) or less, use at least 14 Gauge (AWG) wire size or larger.

If the Loudspeaker Cables are 100 feet (30.48m) or less, use at least 12 Gauge (AWG) wire size or larger.

The Loudspeaker Connection Terminals can accept up to 12 Gauge (AWG) wire.

2.For additional connection information, refer to the owner’s manual(s) for any component(s) connected to the XLS320, XLS340, XLS360 or XCS350 Loudspeaker.

3.The XLS and XCS Loudspeaker Systems have built-in automatic resetting solid-state devices in the crossover networks for protection. The protection allows a certain amount of overdrive, however extended periods of overdrive will trigger protection. If an obvious lack of high, mid or low frequencies is noticed, the Protection Device may have activated. These devices will automatically reset when the volume level is reduced significantly and kept low until the output of the affected Loudspeaker Element returns to normal.

4.When the XLS340, XLS360 or XCS350 Loudspeaker Systems are driven by more than one amplifier, the output levels of the different amplifiers connected to the Loudspeaker System must be adjusted to achieve a proper balance between the low, midrange/high frequencies reproduced. This adjustment is best achieved through the use of audio test equipment operated by a qualified installer.

Introduction

The McIntosh XLS320, XLS340, XLS360 and XCS350 Loudspeaker Systems are designed for Home Theater and Music Reproduction. Many of today’s Loudspeakers are designed only for Home Theater applications, not so with these Loudspeaker Systems. They are also designed for the accurate reproduction of music.

Motion picture sound effects, explosions, screams, and vehicle crashes require a wide dynamic range and high sound levels. These sounds are such that a speaker system having moderate distortion would reproduce them with little audible difference. This is not true with the reproduc- tion of music. Music is by nature and definition harmoni- ous. To reproduce it accurately, all forms of distortion, both harmonic and intermodulation, must be kept to a minimum. This has been the result of the design of the new McIntosh XLS320, XLS340, XLS360 and XCS350 Loudspeaker Systems. Each loudspeaker element and crossover compo- nent has been carefully designed for low distortion, dura- bility and efficiency. The McIntosh XLS320, XLS340, XLS360 and XCS350 Loudspeaker System will reproduce music accurately and function as an excellent Home The- ater Loudspeaker.

The XLS320 is a two-way system with a 6-1/2 inch LD/ HP1 woofer/midrange driver and five 1 inch dome tweeters in a Bessel Function Array. The XLS340 is a three-way system consisting of two 8 inch LD/HP woofers, one 6-1/2 inch LD/HP midrange driver and five 1 inch dome tweeters in a Bessel Function Array. The XLS360 is also a three- way system with two 10 inch LD/HP woofers, one 6-1/2 inch LD/HP midrange driver and five 1 inch dome tweeters in a Bessel Function Array. The XCS350 Center Channel Loudspeaker utilizes two 8 inch LD/HP woofers, one 6-1/2 inch LD/HP midrange driver and five 1 inch dome tweeters in a Bessel Function Array.

The XLS320, XLS340, XLS360 and XCS350 Loud- speaker performance is designed to complement the capa- bilities of McIntosh’s legendary line of Preamplifiers/Con- trol Centers, Signal Sources Devices and Power Amplifi- ers, without imparting distortion or coloration.
