Page 6 - Dividing Networks

The job of the dividing network is to distribute the various frequencies to their respective transducers. The network is also designed to complement component location on the baffle. Slopes are chosen to match the exact response of each driver in its respective frequency range, as well as to ensure ...

Page 7 - Battery Replacement; Figure 1 Battery Installation

The battery should be replaced approximately every 2 years. This is accomplished as follows: • Unscrew the two screws that hold the battery access cover in place. It is located on the upper portion of the dividing network, on the rear of the speaker enclosure (Figure 1). • Write today’s date, includ...

Page 8 - Placement; Figure 2 Placement

Ideally the systems should be placed at least three feet from any walls. The height, at the bottom of the Lens assembly, should be at ear level. The two speakers should be equidistant from your primary listening position; the distance should be determined by the distance between the speakers. We rec...

Page 9 - Speaker Connections

The 4344MkII loudspeakers can be connected by one of several meth- ods. The binding posts on the rear panel of the 4344MkII will accept most types of audio cable and connectors, including banana plugs and bare wire (Figure 3). Follow the hookup method that best describes your system. 1. For each cha...

Figures 5 through 8 show two bi-wiring options, single-stereo amplifier and dual-stereo amplifier modes. For passive and bi-wire connections, set the switch to the Normal/Bi-Wire position (Figure 5a). 1. The external “strapping bars” that normally connect the 4344MkII low-frequency and high-frequenc...

The optimal method of powering the 4344MkII system is with two amplifiers, one for low frequencies and one for the mid/high frequencies. It is necessary to use a high-quality active crossover module. Since each amplifier only drives a limited frequency range, this method allows the user to select am...

Page 13 - Maintenance and Service

The 4344MkII loudspeaker systems have an oiled finish. Cleaning should be done with an untreated dust cloth. Do not use conventional furniture waxes and polishes, which are not designed for oiled finishes. If touch-up is necessary or the finish appears to be drying out, the surface may be re-oiled w...
