Position 3 On = Print Graphs						Off == No Graphs
Position 4 On = Print Text						Off = No Text
If 3 and 4 are both off, Graphs will print.

The M-27 has over 15 million unique setup options. The setup is determined by the position of the three 8-position switches located inside the battery compartment. Externally the setting of these switches can be determined by pressing the CODE key on the front panel and decoding the display by using Figure 17.

If a 4-digit code and either HTL, LTL, or 3 dB is displayed . . .

The first digit is a 1 for a 12 hour clock and a 2 if it is set to 24 hours.

The second determines the weighting, range, upper limit, and the time constant.

The third determines the criterion and exchange rate. The last digit determines the two thresholds. As an example, if the display reads 10EE,

Find the 1 code in the first digit column in Table 2. The clock is 12 hours.

The 0 means the time constant of weighting is "A", the range is 50-146, the upper limit is 115 dB, and the time constant is Slow.

The first E means the criterion is 90 dB and the exchange rate is 5 dB.

80 dB. The second E means the high threshold level (HTL) is 90 dB and the low threshold level (LTL) is If a 3-digit code is displayed with HTL, LTL, and 3 dB ...

The first digit is the unit identification number.

The second digit determines serial or parallel printers and if text, graph, or both will be printed. The last digit determines the printer line feed and carriage return characters and the baud rate. If the code is 53E,

	5 is the unit identification number for this unit. It can be set to any number from 0 to 7. The
number is for user use only and does not affect the operation of the M-27.
baud.	The 3 means it is set for serial printers with both text and graphs. The E means it is set for 600

To convert from decimal to hex or binary refer to Table 1.

To select different options, set the switches by filling in Tables 2 and 3.

As an example, if "A" weighting, 30 to 126 dB range, and a 90 dB upper limit is desired then set the left switch positions 1, 2, and 3 to down, up, and down.

M-27 specifications

AudioQuest M-27 is a standout speaker designed for audiophiles who demand high performance and exquisite sound quality. 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.
