and prints only that data. As an example, if HIST 5 has been pressed, pressing PRINT will print out a heading, a summary, a 5-minute histogram, and a statistical distribution. If HTL is annunciated, pressing HIST 10 will print a 10-minute histogram for the high threshold level only.

It is possible to change the printout while it is printing by pressing PAUSE, other keys, and PAUSE again. Or it can be changed by just pressing another key.

Memory Map

DUMP prints a memory dump of the M-27's random access memory or RAM. Consult the Quest factory if you need a complete description of each memory location.

Editing Printout

 

A complete printout of all the data stored in the M-27 may be more than 25 feet long and may be more than is needed.

If only the data for hearing conservation is required, press CODE/ HL3 until the LTL annunciator is displayed. Pressing PRINT will reduce the data by one-half to two-thirds.

If a 40-column printer is used, turning off TEXT or GRAPH will reduce length of histograms or statistical distribution.

Printing a 3-, 5-, or 10-minute histogram also reduces the printout.

**********************************************************************

Remember data is not erased in the M-27 by any printout. The only way data can be lost is by RESET, removing the battery, or having a dead battery. If a printout is not as desired, another printout may be made. (See page 47 for preserving data during battery change by using a BX-9 accessory.)

*******************************************************************

Other keys change the way data is printed. The keys can be pressed while the printer is printing, not printing, or in pause. As an example, if HIST 5 is pressed part way through the histogram, the rest of the histogram will be a 5-minute histogram.

PAUSE causes the printer to pause while other keys are pressed to redefine the printout. Pressing PAUSE a second time will continue the printout. PAUSE must always be pressed twice, once to stop the

ON/OFF will stop the printout.

If the printer continues to print after pressing PAUSE or ON/OFF, the printer has received an amount of data from the M-27 and stored it in a buffer. In most printers, the buffer can be turned off if desired. See printer manual for details.

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.
