Attach your speaker cables to the signal input section on the rear panel. Be consistent when connecting speaker leads to the terminals on the back of the Fresco. Take great care to assign the same color to the (+) terminal on both the speaker and the amplifier.
Fresco's acoustic equalization to either installation option. Simply set this switch to On Wall if the Fresco is mounted to a wall or ceiling. Set the switch to Off Wall if the Fresco is more than four inches from a wall (see figure 1).
Figure 2. The parts of the Fresco bracket assembly. NOTE: MartinLogan recommends using 5 wall anchors to secure each Fresco to a wall. During the installation, if any of the screw/wall anchor positions are over a stud, it is recommended to screw directly into the stud.
Fresco’s cabinet bracket (installed on the cabinet) should slide down, onto the wall bracket (installed on the wall). Each Fresco should be installed so that it can rotate to point towards your listening position (see figure 3). Hold each Fresco near it's desired location and try pivoting it to assure that each speaker is correctly configured.
2.5mm Allen tool 1 Prepare a flat surface with padding and sheets to pro- tect the speaker as you work on it. Remove the Fresco's grill cloth and carefully place the Fresco face down on the work surface, using books or pieces of cardboard to keep the speaker from rocking.
Determine where the center point of the wall bracket should be marked (see figures 16 and 17). Will the Fresco remain flat against the wall? If so, it can be installed flush against an object such as a plasma screen (see figure18).

ATF (A DVANCED ATF Operation The MartinLogan ATF transducer consists of a micro-thin, low-mass Kaladex diaphragm with an ultra-light, etched conductive aluminum surface suspended between two high field strength neodymium super magnet arrays (see figure 27). When an electrical current (music signal) passes through the...

By positioning neodymium magnet arrays in a push-pull con- figuration, MartinLogan ATF transducer technology maintains uniform diaphragm control, regardless of position as it traverses the entire audio signal. The push-pull concept is a major contributor to the linearity and sonic superiority of ATF transducers.
2 Ohms. Could you suggest a list of suitable electronics and cables that would be ideal for MartinLogan speakers? The area of electronics and cable choice is probably the most common type of question that we receive. It is also the most subjective.

Inductance. The property of an electrical circuit by which a varying current in it produces a varying magnetic field that introduces voltages in the same circuit or in a nearby circuit. It is measured in henrys. Inductor. A device designed primarily to introduce inductance into an electrical circuit.
