Connection

WARNING! Turn your amplifier off before making or breaking any signal connections!

Use the best speaker cables you can. The length and type of speaker cable used in your system will have an audible effect. Under no circumstance should a wire of gauge higher (thinner) than #16 be used. In general, the longer the length used, the greater the necessity of a lower gauge, and the lower the gauge, the better the sound, with dimin- ishing returns setting in around #8 to #12.

A variety of cables are available whose manufactur- ers claim better performance than standard heavy gauge wire. We have verified this in many cases, and the improvements available are often more noticeable than the differences between wires of dif- ferent gauge. The effects of cables may be masked if equipment is not of the highest quality.

Connections are done at the signal input section on the rear electronics panel of the speaker. Use spade connectors for optimum contact and ease of installation. Hand tighten the binding posts, but do not overtighten—do not use a tool to tighten the binding posts.

Be consistent when connecting the speaker cables to the signal input terminals. Take care to assign the same color cable lead to the (+) terminal on both the left and right channel speakers. If bass is nonexistent and you cannot discern a tight, coher- ent image, you may need to reverse the (+) and

(–)leads on one speaker to bring the system into proper polarity.

JUMPER CLIPS

In some countries federal law prohibits MartinLogan from supplying jumper clips. If none are found installed under your speakers binding posts, please refer to ‘Bi-Wire Connection’ for con- nection instructions.
