OPERATION

AC Power Connection

Because your MartinLogan Theater uses an internal power supply to energize its electrostatic cells with high-voltage DC, it must be connected to an AC power source. For this reason it is provided with the proper IEC standard power cord. This cords should be firmly inserted into the AC power receptacles on the rear connection panel of the speaker, then to any convenient AC wall outlet. The Theater integrates a signal sensing power supply which will switch off after a few minutes of no music signal, and requires less than two seconds to recharge the panels when a music signal is present.

Your Theater speaker is wired for the power service supplied in the country of original consumer sale. The AC power rating applicable to a particular unit is specified both on the packing carton and on the serial number plate attached to the speaker.

If you remove your Theater speaker from the country of original sale, be certain that AC power supplied in any subsequent location is suitable before connecting and operating the speakers. Substantially impaired performance or severe damage may occur to the Theater speaker if oper- ation is attempted from an incorrect AC power source.

WARNING! The power cord should not be installed, removed, or left detached from the speaker while the other end is connected to an AC power source.

Signal Connection

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 diminishing returns setting in around #8 to #12.

A variety of speaker cables are now available whose manufacturers claim better performance over 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 different gauge. The effects of cables may be masked if the equipment is not of the highest quality.

We also recommend, if possible, that short runs of speaker cable connect the power amplifier and speaker and that high quality long interconnect cables be used to connect the preamplifier and power amplifier. This results in the power amplifiers being close to the speakers, which may be practically or cosmetically difficult, but if the length of the speaker cables can be reduced to a few meters, sonic advantages may be obtained.

Connections are done at the Signal Input section on the rear electronics panel of the Theater (see figure 1). Use spade connectors for optimum contact. Make certain that all of your connections are tight.

Be consistent when connecting speaker leads to the terminals on the back of the Theater: take great care to assign the same color to the (+) terminal on both the speaker and the amplifier.

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

Break-In

When you first begin to play your Theater speaker, it will sound a bit bass shy. This is due to the high-quality, long-life components used in our woofer. Our custom made, butyl surround woofer requires at least 30 hours of break-in at 90 dB (moderate listening levels) before any critical listening. The break-in requirements of the crossover components (and, to a lesser degree, the electrostatic transducer) are equal.

Center Channel speaker specifications

The MartinLogan Center Channel speaker is a sophisticated audio component designed to deliver a superior listening experience, particularly in home theater setups. Known for its exceptional clarity, dynamic range, and immersive soundstage, this speaker exemplifies high-end audio engineering.

One of the key features of the MartinLogan Center Channel speaker is its use of electrostatic technology. This innovative design employs a thin, lightweight diaphragm suspended between two conductive panels. This allows for superior transient response and reduced distortion, delivering audio that is both clear and detailed. The electrostatic driver provides a unique sound reproduction that immerses the listener in a rich auditory experience, making dialogues crisp and precise.

In addition to its electrostatic driver, the MartinLogan Center Channel speaker typically includes advanced woofers that complement the high-frequency performance. These woofers are engineered to handle lower frequencies effectively, ensuring a balanced sound profile. The integration of these technologies results in a seamless blend of highs and lows, allowing for a full-spectrum audio experience.

The speaker also features a precision-engineered cabinet designed to minimize resonance and reduce colorations. This construction ensures that the sound produced is true to the original recording, preserving the nuances of music and film soundtracks. The cabinet is usually finished to high standards, making it a visually appealing addition to any home theater setup.

Another important characteristic of the MartinLogan Center Channel speaker is its adjustable crossover settings. This allows users to tailor the speaker's performance to fit their specific room acoustics and personal preferences. By fine-tuning the crossover frequency, enthusiasts can achieve an optimal balance across their entire audio system.

Moreover, the speaker is designed with versatility in mind. Its sleek and aesthetically pleasing design allows it to blend seamlessly with modern home decor, while its robust build quality ensures longevity. Whether used in a dedicated home theater, a living room, or a music listening space, the MartinLogan Center Channel speaker delivers an exceptional audio experience that truly elevates the enjoyment of film and music. With its commitment to innovation, craftsmanship, and performance, the MartinLogan Center Channel speaker stands as a premier choice for serious audiophiles and home theater enthusiasts alike.
