Where:

 

 

LS

=

Sound level in dB with slow time constant if the sound level is greater than the

 

threshold level and is -∞if the level is less than the threshold level.

L3

= Sound level in dB without slow time constant.

TC

= Criterion time in seconds or 28800 seconds.

RTIME

= Run time in seconds.

ER

= Exchange rate in dB.

CRIT

= Criterion level in dB.

HTL

=

High threshold level.

LTL

=

Low threshold level.

LHIST

= Level stored each minute for histogram.

LMIN

= Level of histogram printout.

#MIN

= Number of minutes used to compute histogram

% TIME

= The statistical distribution % Time number.

% DOSE

= The statistical distribution % Dose number.

STAT#

= The number of 1/16 second intervals at a level.

LSTAT

= The statistical distribution level.

TESTING AND CALIBRATION

Battery Test

Press any key. If the battery is low, LOB AT will be displayed in the upper left corner of the display. If the battery has at least 8 hours life, LOBAT will be off. If LOBAT is displayed after a day's use, but not at the start of the day, the readings are still good.

Battery Replacement

Loosen the 2 screws on the back of the unit and remove the back. Remove the battery from the cavity and carefully unclip the battery. Replace with a new battery. Take care to observe the polarity of battery and do not reverse the terminals. For best results use a 9 volt alkaline battery. Replace the battery in the compartment and check the display. If it displays 3 dashes replace the back cover. If not check the connections on the battery. The M-27 is now operating in the pause mode. Disconnecting the battery automatically erases stored data in memory. To save data during battery change, use the BX-9 Battery Change Adapter, see page 47.

As part of AudioQuest's commitment to providing unparalleled audio experiences, the M-27 blends advanced technologies with premium materials to deliver exceptional musical clarity and accuracy.

One of the key features of the M-27 is its innovative driver design, which utilizes a new-generation ceramic cone. This cone is engineered to minimize distortion while enhancing transient response. The result is a speaker that offers a clear, detailed sound across a wide frequency range. The drivers are also matched with an advanced neodymium magnet system, ensuring efficient energy transfer and improved bass response.

The M-27 is equipped with a sophisticated crossover network that has been meticulously designed to maintain the integrity of the audio signal. By employing high-quality components, including precision resistors and capacitors, the crossover effectively divides the audio signal into specific frequency bands, allowing each driver to perform at its best. This attention to detail not only enhances sound quality but also helps to create a more cohesive listening experience.

Another notable characteristic of the M-27 is its sturdy and well-constructed cabinet. Built from high-density MDF, the cabinet is engineered to minimize resonance and vibration, which can color sound. Moreover, AudioQuest has incorporated internal bracing to further enhance structural integrity. The elegantly finished exterior not only adds to the speaker's aesthetic appeal but also serves to complement various home decors.

Connectivity is made simple with the M-27, thanks to its standard speaker terminals that accommodate a wide range of wire gauges. This flexibility allows audiophiles to use their preferred cables for optimal performance. Additionally, the speaker is designed to work seamlessly with a variety of amplifier configurations, making it an adaptable choice for different audio setups.

Incorporating these advanced technologies and design principles, the AudioQuest M-27 is not just a speaker; it's a gateway to an immersive listening experience. With its ability to reproduce sound with remarkable accuracy, it will appeal to discerning listeners looking to elevate their audio playback and enjoy their favorite music in a whole new light.
